If you are part of a District of Columbia Domestic Partnership, upon marrying your Domestic Partnership automatically dissolves and you are simply married. If you are part of a Domestic Partnership or Civil Union from another state, the other state’s law may require you to dissolve it prior to marrying in the District of Columbia. Check the other state’s law about your responsibilities and obligations relating to dissolving that legal relationship prior to getting married.
If you are part of a couple who have been legally married in another state or country, or have been registered as domestic partners in jurisdictions that have been certified as substantially similar, there is no need for you to register your marriage or domestic partnership with the city of Washington, DC.
