What section of the Constitution grants marriage license?

The U.S. Constitution does not specifically grant marriage licenses or address marriage directly. Instead, the authority to regulate marriage is reserved to the states under the Tenth Amendment. Each state has its own laws governing the issuance of marriage licenses and the legal recognition of marriages. However, significant Supreme Court rulings, such as Obergefell v. Hodges (2015), have affirmed the right to marry as a constitutional right under the Fourteenth Amendment's Equal Protection and Due Process Clauses.
