Native American Graves Protection Act: What Families Need to Know

What NAGPRA Actually Protects

The Native American Graves Protection and Repatriation Act (NAGPRA), signed into law in 1990, does two things that matter to families right now: it protects burial sites on federal and tribal land from disturbance, and it requires museums and institutions that receive federal funding to return ancestral remains and funerary objects to lineal descendants and culturally affiliated tribes.

That second part is the one most families encounter. As of the most recent regulatory updates, institutions must give deference to traditional tribal knowledge during consultations about affiliation — a significant shift from earlier rules that privileged archaeological interpretation over oral tradition and community records.

NAGPRA applies to remains and objects found on federal or tribal land. It also covers items held by federally funded museums and universities. Private land and privately funded institutions fall outside its scope, which is an important distinction when families are trying to locate ancestral remains.

How Repatriation Actually Works

If your family believes an institution holds ancestral remains or funerary objects connected to your tribe, the process follows a specific path:

1. Contact your tribe's NAGPRA coordinator or tribal historic preservation office for guidance on documenting lineal descent or cultural affiliation with the remains
2. Ask the institution for its inventory and repatriation process — it must follow NAGPRA's consultation and repatriation requirements
3. Consult with the institution's NAGPRA officer on the inventory and any existing determinations of cultural affiliation
4. Coordinate transport with the institution, the tribe, and relevant authorities once repatriation is approved — cross-state or cross-reservation transport may require a burial-transit permit

The reality on the ground is less clean than the statute suggests. Tribal representatives at NAGPRA Review Committee meetings have repeatedly highlighted that many tribes lack the funding and staff to physically transport ancestors home. The burden technically falls on the holding institution, but families often end up coordinating logistics themselves.

Where NAGPRA Falls Short for Grieving Families

NAGPRA's protections are powerful but narrow. It does not cover:

• Private land — if remains are discovered on privately owned property, state law governs what happens next, and state laws vary wildly
• Remains already in tribal custody — once repatriated, tribal law and custom dictate burial and care
• Living family disputes — NAGPRA establishes priority of custody (lineal descendants first, then the tribe on whose land the remains were found, then the culturally affiliated tribe), but it does not resolve family disagreements about how repatriated remains should be reburied

The racial misclassification problem also complicates NAGPRA claims. A 2016 National Center for Health Statistics report found that 48.6% of people who self-identified as American Indian or Alaska Native on the census were classified under an incorrect race or ethnicity on their death certificates. If your ancestor was misclassified, establishing the necessary documentation chain gets harder.

Protecting Active Burial Sites

For families with relatives buried on federal or tribal land, NAGPRA provides meaningful protection against disturbance. Construction projects, land transfers, and archaeological surveys on federal or tribal land must account for the possible presence of burial sites. When remains are inadvertently discovered during such activities, the law requires work to stop, the appropriate tribe to be notified, and a consultation process to begin before anything else happens.

On Navajo Trust Land, additional local regulations apply. Chapter 0029-24, for example, restricts burials to authorized cemeteries with specific plot dimensions (4 feet wide by 9 feet long, at least 6 feet deep) and strictly prohibits cremation or the scattering of ashes.

What Families Should Do Right Now

If you are dealing with a repatriation situation — whether you have just learned that an institution holds your ancestor's remains, or you are trying to ensure a current burial site stays protected — start with these steps:

• Secure a Certificate of Indian Blood (CIB) or Certificate of Degree of Indian Blood (CDIB) from your tribal enrollment department to establish the documentation chain
• Contact the National NAGPRA Program at the National Park Service for guidance on which institutions hold inventoried remains affiliated with your tribe
• Work with your tribal historic preservation officer (THPO) if your tribe has one — they are often the most knowledgeable about active repatriation cases
• Document everything — keep copies of all correspondence with institutions, and note dates and names of people you speak with

For families planning a funeral right now, NAGPRA is less immediately relevant than the practical logistics of working with tribal offices, funeral directors, and burial assistance programs. Our Native American Funeral General Guide walks through the complete planning process from the first hours after a death through burial and memorial rites, including how to navigate BIA burial assistance, tribal burial programs, and the complex web of federal and state regulations that affect Indigenous families.

The Bigger Picture

NAGPRA represented a major acknowledgment that Indigenous peoples have the right to control what happens to their ancestors' remains. Before NAGPRA, an estimated 500,000 to 2 million Native American skeletal remains were held in museums, universities, and federal agencies across the country with little to no input from the communities they came from.

The law is not perfect, and enforcement remains uneven. But for families navigating the intersection of traditional burial practices and modern legal systems, it provides a foundation of rights that did not exist before 1990.
