Final answer:
Eminent domain is the right exercised by a governmental body to take private property for necessary public use. The government must follow a legal process and provide just compensation to the property owners.
Step-by-step explanation:
When a governmental body takes private real property for necessary public use, the legal process that must be followed is an exercise of the right of eminent domain. Eminent domain is the power of the government to take private property for public use, with the presumption that the property is to serve "the public good." The government must pay property owners a fair price for the land in exchange for the taking.
