Indian trust probate: what your family will need, and how to get it ready now
When a tribal member who owns trust land or an Individual Indian Money (IIM) account passes away, the Bureau of Indian Affairs (BIA) gathers documents into a probate file, and a judge at the Department of the Interior decides who inherits. The BIA says gathering those documents “can sometimes take months to complete.” Having the papers below ready, and telling your family where they are, gives them a real head start.
What does the BIA need to prepare a probate case?
Federal rules list what goes into an Indian trust probate file. The BIA needs proof of death, usually a certified death certificate (25 CFR 15.104). It also asks for (25 CFR 15.105):
- Originals or copies of every will, codicil and revocation, or other evidence that a will may exist.
- The person’s Social Security number.
- Where the person and each possible heir are enrolled, with their enrollment or census numbers.
- Current names and addresses of possible heirs.
- Sworn statements about the family, including statements of paternity or maternity.
- Public records, certified if possible: marriage licenses and certificates, divorce decrees, adoption and guardianship records, name changes, and child or spousal support orders.
- A list of known creditors, with copies of any court judgments.
The BIA then adds a family history form showing each heir’s enrollment or other identifying number, a certified inventory of the trust land, and the IIM account balance on the date of death (25 CFR 15.202). Under “Why is it taking so long?”, the BIA explains that collecting papers like death certificates, marriage licenses and adoption decrees depends on the family, and asks heirs to answer requests for information quickly (BIA).
What should be on your family’s checklist?
These 12 items are grouped the way a probate file comes together. Next to each one, write where the original is and who has a copy.
Who you are
- Tribal enrollment card and number. Each Tribal Nation sets its own enrollment rules and keeps its own records, so the Nation’s enrollment office is the place to ask for a copy (BIA).
- Certificate of Degree of Indian or Alaska Native Blood (CDIB). You request it from the BIA agency that serves you. The request uses certified birth certificates to link you to your parents and, if needed, grandparents (BIA CDIB form).
- Birth certificate, from the US or Mexico. A US birth certificate comes from the state vital records office. A Mexican acta de nacimiento can be ordered online at miregistrocivil.gob.mx with your CURP, or at a Mexican consulate (Consulate of Mexico). If a record is in Spanish, ask your BIA agency whether they need a translation.
Your family
- A family tree with each person’s enrollment. List children, spouses and parents, with each person’s Nation, enrollment number and current address. This matches the family history form the BIA prepares (25 CFR 15.202).
- All marriage licenses, including earlier marriages.
- All divorce decrees.
- Adoption papers, for anyone adopted in or out of the family. A CDIB for an adopted person is based on the birth parents’ records (BIA CDIB form).
- Death certificates of a spouse, parents or children who have passed. Who inherits depends on who survived, so these records help the judge confirm the family picture.
Your land and money
- Allotment and tract numbers. The BIA’s Land Titles and Records Offices issue Title Status Reports and Individual Tribal Interest Reports that show ownership (BIA).
- Your latest IIM account statement. Account holders receive a quarterly statement (Interior).
- Your BIA agency and Fiduciary Trust Officer. Write down the office name, phone and the person you work with (Interior).
Your will
- Where the signed original is. The probate file needs the will itself or evidence that one exists (25 CFR 15.105). See writing a will for trust land.
How do you get it ready, step by step?
- Gather what you already have at home: cards, certificates, decrees, statements.
- Request what is missing: enrollment copies from your Nation, a CDIB from your BIA agency, birth records from the state or from Mexico, land reports from the Land Titles and Records Office.
- Write the family tree, with enrollment numbers and current addresses.
- Note where each original is kept and who holds a copy.
- Tell at least two family members where everything is, and who to call at the BIA agency.
What happens after a death is reported?
A family member calls the BIA agency where the person was enrolled (or any BIA agency), or uses the eNativeTrust Family Portal. The BIA confirms the trust assets, builds the probate package and sends it to Interior’s Office of Hearings and Appeals, where a judge decides. Then the BIA updates land records and the Bureau of Trust Funds Administration distributes the money (BIA). The full process is in how Indian trust probate works.
A few property types follow different rules. The BIA notes that allotted restricted land of the tribes federal law calls the “Five Civilized Tribes” and Osage headright interests are generally not probated by Interior (BIA). Your BIA agency can tell you which rules apply to you.
How can your family find everything when the time comes?
The papers matter most when they can be found. Keep originals together in one safe place, keep a list of who holds copies, and write down the names and numbers your family will need to call. That way the people you love can answer the BIA’s questions in days instead of searching for months.

Frequently asked questions
What documents are needed for Indian trust probate?
A certified death certificate, any wills, the enrollment numbers of the person and each possible heir, heirs’ names and addresses, and public records such as marriage licenses, divorce decrees and adoption records. These are listed in 25 CFR 15.104 and 15.105.
Is there a deadline to report a death to the BIA?
No. 25 CFR 15.101 says there is no deadline, but the BIA says reporting as soon as possible leads to a more timely distribution.
Who decides who inherits trust land?
A judge or attorney decision maker at the Department of the Interior’s Office of Hearings and Appeals, Probate Hearings Division, after the BIA sends the probate file.
Can a death be reported online?
Yes. Since July 2026, Interior’s eNativeTrust Family Portal lets families report a death, upload documents, add family history and track the case.
Why do Indian probate cases take so long?
The BIA says gathering documents like death certificates, marriage licenses and adoption decrees can take months, and the judge sends a file back when papers are missing. In 2026, Interior officials also described a backlog of tens of thousands of cases.
