Land Into Trust and Section 20: When Tribes Can Game on New Land

One of the most common misconceptions about tribal gaming is that a tribe can buy a convenient parcel near a highway and open a casino on it. In reality, two distinct legal hurdles stand in the way: the land usually must be held in trust by the United States for the tribe, and — if the tribe acquired it after a key 1988 cutoff — it must qualify under a narrow set of exceptions before any gaming can occur. Understanding these two steps, the fee-to-trust process and Section 20 of the Indian Gaming Regulatory Act, explains why some proposed casinos sail through while others stall for a decade or never open at all.

Step one: getting land into trust

Most tribal gaming takes place on "Indian lands," a defined term that generally means a reservation or land held in trust by the federal government for a tribe or individual Indian. Land a tribe simply owns in fee — like any other private property — does not automatically carry the jurisdictional status that gaming requires. To change that status, a tribe applies to have the land taken "into trust," a process administered by the Bureau of Indian Affairs under the regulations at 25 CFR Part 151.

The fee-to-trust process weighs factors such as the tribe's need for the land, the purpose of the acquisition, the impact on state and local governments, and jurisdictional concerns. It can be straightforward for land on or near an existing reservation and contentious for parcels far from a tribe's historic territory. Crucially, taking land into trust and making it eligible for gaming are two separate questions: trust status is necessary but not sufficient. That second question is where Section 20 comes in. Our legal guide covers the surrounding compact framework, and the distinction between gaming classes is laid out in our Class II versus Class III explainer.

Step two: the Section 20 cutoff

Section 20 of IGRA, codified at 25 U.S.C. 2719, sets a general rule: gaming is prohibited on lands acquired in trust after October 17, 1988, the date IGRA became law. The provision was Congress's answer to a worry that tribes might "reservation shop," acquiring parcels in lucrative urban or suburban markets with little historical connection to the tribe. The default, then, is no — newly acquired lands are presumptively ineligible for gaming.

But the statute carves out exceptions, and most off-reservation casino debates turn on whether a parcel fits one of them. Among the recognized pathways are lands taken into trust as part of the settlement of a land claim, lands that form a tribe's initial reservation following federal acknowledgment, and lands restored to a tribe that was restored to federal recognition. Each exception has its own contours, and disputes frequently center on precise definitions — what counts as "restored" land, for instance, or whether a parcel truly represents an "initial reservation."

The "Indian lands" determination is often the first and most decisive battle in a casino proposal. Regulators and courts parse the history of a parcel closely, and a single eligibility opinion can make or break a project.

The reasoning behind these exceptions matters as much as the list itself. Congress did not want to freeze tribes that were landless in 1988, newly acknowledged after that date, or in the middle of resolving historic claims out of the gaming economy entirely. The exceptions are therefore tied to a tribe's legitimate, often court-recognized connection to particular land rather than to mere commercial convenience. That is why eligibility fights so often become historical and anthropological arguments about a parcel's place in a tribe's past, not just legal ones about the present.

One especially debated route is the two-part determination. Under it, the Secretary of the Interior may permit gaming on after-acquired land if the Secretary finds that a gaming establishment would be in the best interest of the tribe and its members and would not be detrimental to the surrounding community — and, critically, the governor of the state must concur. That gubernatorial concurrence requirement gives states a powerful veto and is one reason two-part determinations are comparatively rare.

Why it matters

These rules shape the geography of tribal gaming. They explain why casinos tend to cluster on or near historic reservations, why some tribes spend years pursuing a single off-reservation site, and why eligibility opinions from federal regulators draw intense scrutiny from competitors, local governments and other tribes. A recent example of how granular these determinations get can be seen in our coverage of the Grand Traverse Band Indian lands opinion, where the status of specific acreage was the entire question.

For anyone following a proposed casino, the practical takeaway is to separate the headlines from the legal reality. A tribe announcing a land purchase is at the very beginning of a long road, not the end of it. The parcel must clear the fee-to-trust process and then satisfy Section 20, and only then can compacting and construction proceed.
