The Short Answer

The government must pay 'just compensation'—typically the fair market value of the property—for any private property taken for public use under the Fifth Amendment.

What the Law Says

The Fifth Amendment to the U.S. Constitution is the foundational source for the government’s obligation to pay compensation when it takes private property. While 40 U.S.C. § 3111 governs internal federal acquisition procedures—including title review—it does not define or set the amount of compensation. That duty flows from the Constitution, not this statute.

The U.S. Constitution’s Takings Clause states: 'nor shall private property be taken for public use, without just compensation.' This applies to all levels of government but is enforced against federal action directly through the Fifth Amendment.

40 U.S.C. § 3111 deals only with internal federal real estate acquisition logistics. It requires federal agencies to obtain approval of title sufficiency before acquiring property—but says nothing about valuation, compensation standards, or claimant rights.

In practice, just compensation is almost always determined as the property’s fair market value at the time of the taking—what a willing buyer would pay a willing seller, with neither under compulsion to buy or sell.

Statutory Text

The head of an executive agency may acquire real property for the agency by purchase, condemnation, or other appropriate means.

What to Do

1

Confirm whether the taking is formal (via condemnation lawsuit) or informal (e.g., physical occupation or regulatory action).

2

Obtain an independent appraisal of the property’s fair market value as of the date of taking.

3

File a claim in the U.S. Court of Federal Claims within 6 years of the taking (28 U.S.C. § 2501).

4

Request a jury trial on compensation if filing under the Tucker Act (28 U.S.C. § 1491).

5

Consult an attorney experienced in eminent domain or takings law.
