What is the term for the voluntary transfer of land to the government?

The term for the voluntary transfer of land to the government is "dedication." This term specifically refers to the act of property owners setting aside land for public use, often to establish parks, streets, or other community facilities. Dedication is typically formalized through a written document and accepted by the governmental body.

In contrast, terms like "donation" or "gift" do not specifically imply a transfer intended for public use or governmental purposes. While a donation or gift can refer to the act of giving something without expecting anything in return, these terms lack the formal context and purpose associated with "dedication." "Donation by deed" also implies a written transfer but does not emphasize the specific intention of making land available for public use, which is central to the concept of dedication.
