The government's power to take private property for public use, which the Constitution allows only with just compensation, and the owner's rights when it does.

Eminent domain is the power of the federal, state and local governments, and of some utilities and other entities they authorize, to take private property for public use. The Fifth Amendment limits it: private property may not be taken for public use without just compensation, and the same limit applies to the states. The formal process is condemnation, in which the government makes an offer, and if the owner does not accept, files a court case in which the main question is usually what compensation is owed.
"Public use" is read broadly. The Supreme Court held that a city could take homes for a private economic development plan expected to benefit the public (Kelo v. City of New London, 545 U.S. 469 (2005)). Many states responded by restricting takings for economic development under their own constitutions and statutes, so state law often gives owners more protection than the federal minimum. Just compensation is generally the property's fair market value (United States v. 564.54 Acres of Land, 441 U.S. 506 (1979)). When only part of a property is taken, damage to the value of the remainder can be compensable, and the federal Uniform Relocation Assistance Act provides relocation payments and services to people displaced by federally funded projects (42 U.S.C. § 4601 et seq.).
A taking can also happen without condemnation. If the government physically occupies property, or a regulation goes so far that it amounts to a taking, the owner can bring an inverse condemnation claim. A regulation that deprives land of all economically beneficial use is a taking (Lucas v. South Carolina Coastal Council, 505 U.S. 1003 (1992)), other regulations are judged by their economic impact and character (Penn Central Transportation Co. v. New York City, 438 U.S. 104 (1978)), a regulation granting a right of physical access to private property is a per se taking (Cedar Point Nursery v. Hassid, 594 U.S. 139 (2021)), and an owner may bring a federal takings claim in federal court without first suing in state court (Knick v. Township of Scott, 588 U.S. 180 (2019)).
Do not accept or reject the first offer before getting your own appraisal and advice: the government's appraisal may leave out damage to the remaining property, business losses where state law allows them, or relocation benefits. Some states require the government to pay part of the owner's appraisal or legal costs, and many eminent domain lawyers are paid from the increase they obtain over the offer. Deadlines to challenge the taking itself can be short, so act when you first receive notice.
Worried about the cost? A lawyer can be hired for one part of a case only (limited-scope representation), may be paid from what a claim recovers (contingency fee), or may be free through a pro bono program or legal aid; a court can also waive its own filing fees.
