University City, MO (KSDK) - University City has become the first municipality in St. Louis County to establish a domestic partnership ordinance.

The city council voted Monday to establish a registry that would provide those in the partnership the same rights as spouses to all in city facilities and in city operations.

To register a domestic partnership, both people must share a common residence; affirm that they share responsibility for each other's common welfare; not be married to a third party; not be part of an existing domestic partnership registry with any third party; and must be 18 years or older.

St. Louis already has a same-sex domestic partner registry established, as well as Kansas City, Columbia, and Jackson County.

University City couples can start registering a domestic partnership beginning May 10.
