Tribal Law and Indian Country Jurisdiction: Sovereignty, Criminal Authority, and ICWA

Summary. Who has authority over what, where, and against whom — and how the child welfare statute works.

Part I: A third sovereign

American law recognizes three kinds of sovereign: the federal government, the states, and Indian tribes. Tribes are not creatures of federal law and are not subdivisions of states. They are pre-constitutional political communities whose sovereignty predates the United States and, as the Supreme Court has repeatedly put it, is inherent rather than delegated — diminished in specific ways by treaty, by statute, and by implication from their dependent status, but not otherwise.

The foundational statement is Worcester v. Georgia, which held that the Cherokee Nation was a distinct community occupying its own territory in which the laws of Georgia had no force. The modern law has qualified that considerably, but its premise survives: tribal authority is inherent, and state authority in Indian country is the exception rather than the rule.

Three facts must be established before any jurisdictional question can be answered:

Where did it happen? Inside or outside Indian country.
Who are the parties? Indian or non-Indian — for both the defendant and, in criminal cases, the victim.
What kind of case is it? Criminal or civil, and if criminal, what offense.

Change any one of the three and the answer changes. This is not a doctrine that can be summarized in a sentence, and lawyers who try to guess it are wrong at a high rate.

Part II: Indian country

18 U.S.C. § 1151 defines Indian country as: all land within the limits of any Indian reservation under federal jurisdiction, notwithstanding the issuance of any patent and including rights-of-way running through the reservation; all dependent Indian communities; and all Indian allotments to which title has not been extinguished.

The first clause did enormous work in McGirt v. Oklahoma, which held that the Muscogee (Creek) reservation established by treaty had never been disestablished by Congress, and therefore remained Indian country for purposes of the Major Crimes Act — notwithstanding a century of contrary practice and the fact that most residents are not tribal members. The Court's reasoning was textual: only Congress can disestablish a reservation, and it must do so clearly.

The consequence was jurisdictional reallocation on a large scale, and the subsequent litigation has been extensive.

Note what Indian country is not. It is not defined by ownership. Land owned in fee by a non-Indian within reservation boundaries is still Indian country under the statute, which is why the "checkerboard" pattern created by allotment produces such difficult problems.

Part III: Criminal jurisdiction — the grid

Three statutes and one case create the framework.

18 U.S.C. § 1152 — the General Crimes Act. Federal enclave law extends to Indian country, except offenses committed by one Indian against another Indian, offenses by an Indian already punished by the tribe, and cases where a treaty gives the tribe exclusive jurisdiction.

18 U.S.C. § 1153 — the Major Crimes Act. Federal jurisdiction over enumerated serious offenses — murder, manslaughter, kidnapping, sexual offenses, assault with a dangerous weapon, arson, burglary, robbery, and others — committed by an Indian in Indian country, regardless of the victim's status.

18 U.S.C. § 1162 — Public Law 280. In listed states, and in others that later assumed jurisdiction, state criminal jurisdiction was extended over offenses by or against Indians in Indian country, with federal jurisdiction correspondingly withdrawn. Whether a state is a Public Law 280 state changes every answer, and the coverage is partial and state-specific.

Oliphant v. Suquamish Indian Tribe held that tribes lack inherent criminal jurisdiction over non-Indians — a decision that created the enforcement gap that has defined the field ever since.

The gap has been partially closed by statute. Congress restored a limited special criminal jurisdiction permitting participating tribes to prosecute non-Indians for domestic violence, dating violence, protection order violations, and — as later expanded — certain related offenses including sexual violence, stalking, child violence, obstruction, and assaults on tribal justice personnel. It comes with required procedural protections for defendants, including a right to counsel and a jury drawn from a fair cross-section.

And Oklahoma v. Castro-Huerta changed the grid again, holding that states have concurrent jurisdiction to prosecute crimes committed by non-Indians against Indians in Indian country — a significant departure from the prior understanding that such cases were exclusively federal.

The result, in rough summary and subject to Public Law 280 and treaty variations:

Defendant	Victim	Jurisdiction
Indian	Indian	Tribal; federal for Major Crimes Act offenses
Indian	Non-Indian	Tribal; federal (Major Crimes Act or General Crimes Act)
Non-Indian	Indian	Federal; state, concurrently, after Castro-Huerta
Non-Indian	Non-Indian	State
Non-Indian	Domestic violence against Indian	Tribal, under the restored special jurisdiction, plus federal and state

Tribal sentencing authority is capped by statute, with a higher cap available to tribes providing enhanced procedural protections including licensed defense counsel and a law-trained judge.

Part IV: Civil jurisdiction

The framework is Montana v. United States, which established a general rule with two exceptions: absent express congressional delegation, a tribe's inherent sovereign powers do not extend to the activities of nonmembers, except that a tribe may regulate —

Consensual relationships with the tribe or its members, through commercial dealing, contracts, leases, or other arrangements; and
Conduct that threatens or has some direct effect on the political integrity, economic security, or health or welfare of the tribe.

These exceptions are narrower in practice than they read, particularly on non-Indian fee land within a reservation, and the case law is unforgiving.

But note the other side. Williams v. Lee held that a state court lacked jurisdiction over a suit by a non-Indian merchant against Navajo defendants arising on the reservation, because it would infringe on the right of reservation Indians to make their own laws and be ruled by them. The infringement test remains good law and it is frequently the answer where a non-Indian sues an Indian defendant over on-reservation conduct.

Exhaustion of tribal remedies. Where tribal court jurisdiction is colorable, federal courts generally require that the tribal court be allowed to determine its own jurisdiction first, with the federal question available afterward. This is a rule practitioners forget and courts enforce.

Part V: Sovereign immunity

Tribes possess sovereign immunity from suit, absent a clear waiver by the tribe or unequivocal abrogation by Congress.

Michigan v. Bay Mills Indian Community reaffirmed the doctrine and applied it to off-reservation commercial conduct, declining an invitation to narrow it and pointing to Congress as the body to change it.

The practical consequences are large:

A contract with a tribe or a tribal enterprise must contain an express waiver of immunity, identifying the forum and the scope, or there may be no remedy at all.
Immunity extends to arms of the tribe — enterprises and agencies — under multi-factor tests that vary by circuit.
Officials may sometimes be sued for prospective relief notwithstanding tribal immunity.
Insurance may effect a limited waiver, depending on the policy and tribal law.

For anyone doing business with a tribe, the waiver clause is the most important clause in the agreement. See Contract Lifecycle Toolkit.

Part VI: The Indian Civil Rights Act

Because the Bill of Rights constrains federal and state governments, not tribes, Congress imposed a statutory analogue. 25 U.S.C. § 1302 applies most — but not all — of the Bill of Rights to tribal governments, with modifications: there is no establishment clause provision, no requirement of appointed counsel in every case (though enhanced sentencing requires it), and no grand jury requirement.

The enforcement limitation is the crucial point. Santa Clara Pueblo v. Martinez held that the Act does not create a federal cause of action against a tribe or its officers except by habeas corpus. Other claims must be brought in tribal court under tribal law.

So the remedy for a rights violation by a tribal government is generally tribal, which makes the quality and independence of tribal courts a matter of real consequence — and which is why tribal appellate systems have developed substantially over recent decades.

Part VII: Tribal courts

There are hundreds of tribal courts, and they vary enormously: some are large systems with law-trained judges, published codes, appellate courts, and reported decisions; others are small courts applying custom and tradition, with lay judges and oral procedure. Some tribes operate under Courts of Indian Offenses administered federally.

Recognition of tribal judgments. Federal statutes require full faith and credit for tribal protection orders and for certain child support and ICWA-related orders. Beyond those, recognition generally proceeds under comity — state by state, with some states adopting reciprocal statutes or court rules. Do not assume a tribal judgment will be enforced in state court without checking the state's rule.

Practicing in tribal court requires attention to details lawyers take for granted elsewhere: bar admission is separate and often requires a tribal bar exam or sponsorship; the applicable law may include tribal custom and tradition as a source; procedure may be governed by a tribal code rather than familiar rules; and the substantive law may differ in ways that matter, particularly in family and property matters.

Part VIII: The Indian Child Welfare Act

Congress enacted the Act in response to the removal of Indian children from their families and tribes at rates that threatened the continued existence of tribal communities. It is the provision of federal Indian law that state court practitioners encounter most often, and it is the one most often mishandled.

Scope. It applies to child custody proceedings — foster care placement, termination of parental rights, preadoptive placement, and adoptive placement — involving an Indian child, meaning an unmarried person under eighteen who is either a member of a tribe or eligible for membership and the biological child of a member. It does not apply to custody disputes between parents in a divorce.

Jurisdiction. Under 25 U.S.C. § 1911, a tribe has exclusive jurisdiction over a child residing or domiciled on the reservation, and concurrent jurisdiction otherwise, with a right to intervene and a presumption in favor of transfer to tribal court absent good cause or a parent's objection.

Procedure. 25 U.S.C. § 1912 requires notice to the parent, the custodian, and the tribe by registered mail with return receipt; appointment of counsel for an indigent parent; access to the reports on which the proceeding rests; active efforts to provide remedial services and rehabilitative programs designed to prevent the breakup of the Indian family; and, for foster placement, clear and convincing evidence including the testimony of a qualified expert witness that continued custody is likely to result in serious emotional or physical damage — rising to beyond a reasonable doubt for termination of parental rights.

"Active efforts" is a higher standard than the "reasonable efforts" required in ordinary dependency cases, and it is the requirement most frequently litigated.

Placement preferences. 25 U.S.C. § 1915 establishes an order of preference — for adoption: extended family, other members of the child's tribe, then other Indian families; for foster or preadoptive placement: extended family, a tribally licensed or approved home, an Indian-licensed foster home, or an institution approved by the tribe. A tribe may alter the order by resolution, and a departure requires good cause, which must be established on the record.

And the constitutional challenge failed. Haaland v. Brackeen rejected challenges under the Commerce Clause, the anticommandeering doctrine, and — for want of standing — equal protection, leaving the statute in force. Assume it applies and comply with it.

The single most common failure in practice is notice. Ask the inquiry question at the first hearing — "Does any party have reason to know this is an Indian child?" — document the answer, send notice by registered mail with return receipt to every tribe with a possible connection and to the Bureau of Indian Affairs, and wait the statutory period before proceeding. Defective notice is the leading ground on which adoptions and terminations are invalidated years later, which is catastrophic for everyone involved, most of all the child.

Part IX: Gaming, land, and economic development

Gaming. 25 U.S.C. § 2701 opens the Indian Gaming Regulatory Act, which creates three classes: Class I traditional and social games, exclusively tribal; Class II bingo and certain card games, tribally regulated with federal oversight; and Class III casino-style gaming, permitted only under a tribal-state compact and only where the state permits such gaming for any purpose.

Land into trust. The Secretary of the Interior may acquire land in trust for tribes, which changes its jurisdictional status and generally removes it from state taxation and regulation. The process is contested, slow, and frequently litigated by neighboring jurisdictions.

Taxation. State taxation of on-reservation activity is subject to preemption analysis and to the infringement test, with the outcome depending heavily on the incidence of the tax, the federal regulatory scheme, and whether the burden falls on the tribe or on non-Indians.

Employment. Tribal employment preference is expressly permitted in defined contexts, and the general employment discrimination statutes exclude tribes from the definition of "employer" — but a tribal enterprise operating off-reservation, or a non-tribal employer on a reservation, faces a different analysis.

Part X: Five problems

The car accident on the reservation highway

A non-Indian driver and a tribal member collide on a state highway running through a reservation. The tribal member sues the non-Indian in tribal court.

Start with the three facts. Location: within reservation boundaries, and a right-of-way through a reservation is expressly Indian country under 18 U.S.C. § 1151. Parties: non-Indian defendant, Indian plaintiff. Case type: civil.

Then apply Montana. Tribal civil authority over nonmembers is the exception. Does either exception apply? A consensual relationship — the driver holds no tribal license and has no commercial dealing with the tribe, so probably not on these facts alone. Direct effect on health or welfare — a traffic collision injuring a tribal member on a road through the reservation is an argument, and courts have divided on how far it reaches.

But the practical answer for the defendant is not to file in federal court immediately. Where tribal jurisdiction is colorable, exhaustion of tribal remedies is generally required first: the tribal court gets to decide its own jurisdiction, and the federal question comes afterward. Removing or racing to federal court before exhaustion is the classic and expensive error.

And the reverse case matters too. If the non-Indian sued the tribal member in state court over the same collision, Williams v. Lee's infringement test asks whether state adjudication would undermine the tribe's authority to govern itself — and on-reservation conduct with an Indian defendant is where that test bites hardest.

The contract with a tribal enterprise

A construction company contracts with a tribal housing authority. The project goes badly and the company wants to sue.

The first question is not the breach. It is immunity. Under Bay Mills, tribal sovereign immunity is broad, applies to commercial conduct, and applies off-reservation. Without an express waiver there may be no remedy at all.

What the contract should have said:

An express, unequivocal waiver of sovereign immunity for claims arising under the agreement.
The forum — tribal court, state court, federal court, or arbitration — and, if arbitration, the seat, the rules, and consent to confirmation of the award in a named court.
The scope: which claims, up to what amount, and whether limited to specified assets or revenues.
Whether the waiver binds arms of the tribe and named entities.
The governing law.
Who has authority to waive under tribal law, with evidence — a resolution of the governing body, not a manager's signature.

Without those, the company's realistic options are to look for a limited waiver in an insurance policy, to consider claims against officials for prospective relief, to pursue whatever tribal administrative remedy exists, and to negotiate. The lesson is entirely preventive, and it belongs in every checklist for contracting with a tribe or a tribal entity.

The domestic violence case at the boundary

A non-Indian assaults his tribal-member partner at their home on the reservation.

Historically this was the enforcement gap — Oliphant barred tribal prosecution of non-Indians, federal resources were distant, and states lacked jurisdiction. Cases went unprosecuted.

Three things have changed. Congress restored a special criminal jurisdiction permitting participating tribes to prosecute non-Indians for domestic and dating violence, protection order violations, and — as expanded — related offenses, with required protections for defendants including licensed defense counsel, a law-trained judge, and a jury from a fair cross-section. Federal jurisdiction remains under 18 U.S.C. § 1152. And Castro-Huerta added concurrent state jurisdiction over crimes by non-Indians against Indians in Indian country.

For the victim, the practical points are:

Tribal protection orders are entitled to full faith and credit across jurisdictions by federal statute — a rare and valuable rule.
More than one prosecuting authority may have jurisdiction; ask each.
Tribal victim services, and federally funded advocacy programs, exist and are frequently better resourced than the equivalent county service.

See Domestic Violence and Protective Orders.

The dependency case with an unasked question

A county child welfare agency files a dependency petition. Nobody asks whether the child may be an Indian child. Eighteen months later, after a termination of parental rights and a completed adoption, the tribe learns of the case.

This is the most consequential recurring failure in state court practice, and it is entirely preventable.

What should have happened at the first hearing: the court asks each party whether they have reason to know the child is an Indian child, on the record; the agency conducts further inquiry with extended family; notice goes by registered mail with return receipt to every tribe with a possible connection and to the Bureau of Indian Affairs; and the proceeding waits the statutory period.

What happens now: a challenge to the judgment, potentially years later, with a child who has been in a placement for most of their life. Everyone loses, and the loss is greatest for the child.

The fix costs one question and one letter. Ask it at the first hearing, every time, and document the answer in the minute order.

The reservation that was never disestablished

After McGirt, a large area long treated as ordinary state territory is confirmed to remain a reservation, and therefore Indian country.

What changes: criminal jurisdiction over offenses by Indians shifts to federal and tribal authorities under the Major Crimes Act at 18 U.S.C. § 1153; tribal civil authority over members is confirmed; and the Montana analysis governs nonmembers.

What does not change: land ownership, which is unaffected; most day-to-day regulation of non-Indians on fee land; and — after Castro-Huerta — state jurisdiction over crimes by non-Indians against Indians.

What it produces in practice: enormous volumes of post-conviction litigation, cross-deputization agreements between tribal, state, and federal law enforcement, and negotiated arrangements on taxation and regulation. The durable lesson is textual: reservation boundaries persist until Congress clearly disestablishes them, and a century of contrary administrative practice does not do it.

Part XI: The trust relationship and federal programs

Underlying everything above is a relationship the Supreme Court has described as resembling that of a guardian to a ward — a trust relationship between the United States and tribes, arising from treaties, statutes, and course of dealing.

What it produces concretely:

Trust land. Most reservation land is held by the United States in trust for a tribe or for individual Indians. This has real consequences: trust land generally cannot be alienated or encumbered without federal approval, is generally exempt from state and local taxation, and is subject to federal leasing and rights-of-way requirements. Financing a project on trust land is therefore a specialized exercise, because the usual mortgage security does not work in the usual way, and leasehold mortgage structures with federal approval are the norm.

Fractionation. Allotment divided land among individual owners, and successive generations of intestate inheritance produced parcels with hundreds of undivided fractional owners — a problem that makes consolidation, leasing, and development enormously difficult and that federal programs have attempted to address through purchase and consolidation.

Probate. Trust interests pass under a federal probate system administered by the Department of the Interior, distinct from state probate, with its own rules governing who may inherit and how interests may be devised. A will disposing of trust land must satisfy that system, and a state-law will alone does not do it. See Probate and Estate Administration.

Federal services. Health, education, housing, law enforcement, and social services are delivered through federal agencies and through tribally operated programs under self-determination contracts and compacts — an arrangement that transfers administration to tribes while retaining federal funding obligations.

Trust mismanagement claims. Where the United States has assumed control over tribal resources, breaches of the trust obligation have supported damages claims, and several have produced very large settlements.

And an interpretive canon. Ambiguities in treaties, statutes, and executive orders are construed liberally in favor of the Indians, with treaties interpreted as the Indians would have understood them at the time. This canon appears throughout the case law and is a real tool, not a rhetorical one.

Part XII: The urban and off-reservation reality

A majority of Native people do not live on reservations, and the doctrine above — organized around territory — addresses their situation poorly.

Off-reservation, general law applies. State criminal and civil jurisdiction is ordinary. Tribal jurisdiction is generally absent. The distinctive rules of Indian country simply do not operate.

But four things follow a person rather than a place:

ICWA follows the child. The statute applies wherever the state proceeding is, including in cities far from any reservation. The inquiry and notice obligations are identical. This is the single most important point for urban practice.

Tribal membership follows the person, with its attendant rights to services, participation in tribal government, and — in some contexts — hunting, fishing, and gathering rights secured by treaty.

Federal programs and services are available in many cases through urban Indian health organizations and other providers, independent of residence.

Treaty rights to hunt, fish, and gather at usual and accustomed places, secured by treaty, may be exercised off-reservation and are enforceable — a body of law with its own extensive litigation, particularly regarding fisheries and habitat.

And a practice note. For a lawyer in a city, the realistic touchpoints with this field are: a child welfare case triggering ICWA; a client whose criminal conduct occurred in Indian country; a contract with a tribal entity; a probate involving trust interests; and an employment or benefits question turning on tribal employment. Knowing to ask the question is most of the work.

Part XIII: Working in this field

Establish the three facts first: location, status of the parties, and type of case. Do not analyze before you have them.
Check whether the state is a Public Law 280 state, and whether the particular tribe or the particular subject matter is covered — the coverage is partial.
Read the tribal code. Many are published. It is the governing law, and assuming it mirrors state law is the classic error.
Assume sovereign immunity applies unless there is an express waiver, and read the waiver's scope and forum with care.
Exhaust tribal remedies where tribal jurisdiction is colorable.
Ask the ICWA question at the first hearing, in every child custody proceeding, and document the answer.
Consult the tribe. Tribal attorneys general, ICWA directors, and tribal courts are accessible and are the best source on their own law.

Part XIV: How the law got this way

The jurisdictional grid looks arbitrary because it is sedimentary — each layer deposited by a different policy era, and none of the earlier layers fully removed.

Treaty-making, to 1871. Tribes were treated as nations and dealt with by treaty. Worcester belongs to this period, and the treaties themselves remain enforceable federal law — which is why a nineteenth-century treaty can decide a twenty-first-century case.

Removal and reservation, mid-1800s. Tribes were relocated and confined to defined territories. The reservation boundaries created then are the boundaries litigated now, as McGirt demonstrated.

Allotment, from 1887. Communal land was divided into individual parcels, with the "surplus" opened to non-Indian settlement. Tribal landholdings fell dramatically, and the checkerboard pattern of tribal, individual trust, and non-Indian fee land within reservation boundaries — the source of most modern jurisdictional difficulty — dates entirely from this policy. So does fractionation.

Reorganization, from 1934. Allotment ended, tribal governments were reconstituted under federally approved constitutions, and land could again be taken into trust. Many tribal governments and codes trace their present structure to this era.

Termination, 1950s and 1960s. Congress terminated the federal relationship with more than a hundred tribes and enacted Public Law 280, transferring criminal and some civil jurisdiction to certain states. Termination was later repudiated and many tribes restored, but Public Law 280 remains, which is why the jurisdictional answer still depends on which state you are in.

Self-determination, from 1970 to the present. Federal policy reversed toward supporting tribal self-government, with tribes contracting and compacting to run their own health, education, law enforcement, and social service programs. The Indian Civil Rights Act, the Indian Child Welfare Act, and the Indian Gaming Regulatory Act all belong to this period.

Why the history matters practically. It explains why the answer to a jurisdictional question turns on a treaty from 1855, an allotment patent from 1904, a state's decision under Public Law 280 in 1957, and a tribal code adopted in 1988 — all at once. It also explains the interpretive canon: because these arrangements were imposed on parties with unequal bargaining power and often in languages the signatories did not read, ambiguities are resolved in favor of the tribes and treaties are read as the Indians would have understood them.

Part XV: What tribal courts are actually like

Practitioners who have never appeared in one imagine either a state court with different letterhead or something unrecognizable. Neither is right.

The range is enormous. Some tribal judiciaries are substantial systems — multiple trial divisions, a court of appeals, published opinions, law-trained judges, a written code, and a bar with an admission examination. Others are small courts serving a few hundred people, with a lay judge, a spokesperson tradition rather than an adversarial bar, and procedure set by custom. Some tribes have no court of their own and are served by a Court of Indian Offenses operating under federal regulation.

What is commonly different from state practice:

Sources of law. A tribal code, then tribal custom and tradition, then — often expressly — state or federal law as persuasive or as a gap-filler. Custom is a genuine source of decision in many jurisdictions, provable by elder testimony, and a lawyer who treats it as decoration will lose.

Peacemaking and restorative processes. Many systems maintain a mediation or peacemaking track alongside the adversarial one, sometimes mandatory for family and community disputes, and often the preferred route.

Procedure. Governed by the tribal code. Discovery may be narrower, deadlines different, motion practice lighter, and hearings less formal. Read the code before assuming any rule.

Admission. Separate from any state bar. Frequently requires an application, sometimes a tribal bar examination on tribal law, sometimes sponsorship by an admitted member, and often a fee. Do this weeks in advance, not the day before a hearing.

Lay advocates. Many tribal courts admit non-lawyer advocates, who may be experienced, effective, and better versed in the tribe's law than visiting counsel.

Appeals. Tribal appellate courts are real courts producing real bodies of law, and several inter-tribal appellate systems serve multiple tribes.

How to appear well:

Read the code and the court's rules first. They are frequently online.
Get admitted early.
Call the clerk. Tribal court clerks are generally helpful and are the fastest route to how things are actually done.
Learn the protocol — forms of address, whether an opening prayer or statement is customary, whether elders are present, and whether the proceeding is conducted in a language other than English.
Do not condescend. A visiting lawyer who signals that this is not a real court is remembered by a judge who will see them again, and who is entirely capable of ruling accordingly.
Do not assume state law applies. It usually does not, and citing it as though it controls is the most common error.

And note the recognition question. A judgment obtained in tribal court is entitled to full faith and credit for protection orders and certain child support and ICWA orders by federal statute; beyond that, enforcement in state court proceeds under comity, which varies by state. Check the destination state's rule before you rely on a tribal judgment being enforceable there.

Part XVI: ICWA compliance in practice

The statute is short and the compliance failures are predictable. Here is what actually goes wrong, in order.

1. The question is never asked. 25 U.S.C. § 1912 obligations are triggered by reason to know the child is an Indian child. The inquiry should occur at the first hearing, on the record, of every party — and the agency should continue inquiring of extended family, not just the parents, since a parent may not know or may not say.

2. Notice goes to the wrong place, or by the wrong method. Notice must go by registered mail with return receipt to the parent or Indian custodian and to each tribe with a possible connection — and to the Bureau of Indian Affairs where the tribe cannot be determined. Certified mail is not registered mail in the statute's terms, and the return receipts belong in the file.

3. The proceeding moves before the waiting period expires. The statute forbids a foster placement or termination proceeding until at least ten days after receipt of notice, with an additional twenty days available on request. Proceeding early is a defect that travels with the case forever.

4. "Reasonable efforts" are documented instead of "active efforts." These are different standards. Active efforts are affirmative, thorough, and culturally appropriate — identifying services, assisting the parent in engaging with them rather than referring and waiting, involving the tribe, and using the tribe's own resources and extended family network. Document the effort, not the referral.

5. The expert witness is not qualified. The statute requires testimony of a qualified expert witness on whether continued custody is likely to result in serious emotional or physical damage. Qualification generally turns on knowledge of the tribe's social and cultural standards and childrearing practices — not merely a clinical credential. A caseworker who has never worked with the tribe is not that witness.

6. The standard of proof is wrong. Clear and convincing for foster placement; beyond a reasonable doubt for termination of parental rights. Both include the qualified expert testimony.

7. Placement preferences are departed from without a record. 25 U.S.C. § 1915 sets the order, the tribe may alter it by resolution, and a departure requires good cause established on the record — with reasons that do not reduce to convenience or the placement's socioeconomic status.

8. The tribe is treated as a party to be notified rather than a participant. The tribe has a right to intervene at any point and a presumptive right to transfer to tribal court under 25 U.S.C. § 1911, absent good cause or a parent's objection. Call the tribe's ICWA director early. They are the best source on the child's family, on available placements, and on the tribe's own preferences.

Why this matters beyond compliance. Haaland v. Brackeen left the statute standing, so it applies. But the deeper point is that defective compliance produces judgments that are vulnerable for years — and the person who bears the cost of an adoption unwound after four years is a child. Getting it right at the first hearing is not paperwork; it is the substance.

Frequently asked questions

Can a tribe prosecute a non-Indian? Generally no under Oliphant — but yes under the restored special criminal jurisdiction for domestic violence and related offenses, with required procedural protections.

Can a state prosecute a non-Indian who harms an Indian on a reservation? Yes, concurrently with the federal government, after Castro-Huerta.

Is land owned by a non-Indian inside a reservation still Indian country? Yes. The definition turns on reservation boundaries, not ownership.

Can I sue a tribe? Only with an express waiver of sovereign immunity or congressional abrogation. Put the waiver in the contract.

Does ICWA apply to a custody dispute in a divorce? No. It applies to foster placement, termination of parental rights, and preadoptive and adoptive placement.

What is "active efforts"? A higher standard than the "reasonable efforts" of ordinary dependency practice — affirmative, thorough, culturally appropriate efforts to prevent the breakup of the Indian family.
