An Affidavit of Domestic Partnership is a written document that serves as proof of the existence of a domestic partnership between two individuals. This document, which is sometimes referred to as a Declaration of Domestic Partnership or a Domestic Partnership Agreement, is used to establish a joint financial relationship between two people who are not married but who have a committed relationship. This document also provides a proof of the relationship for legal purposes. There are two types of Affidavit of Domestic Partnership: a short-term affidavit and a long-term affidavit. A short-term affidavit is usually used for couples who are living together for a short period of time, and it does not establish long-term rights and obligations between the partners. A long-term affidavit, on the other hand, establishes long-term rights and responsibilities between the partners and usually requires more information than a short-term affidavit. Generally, an Affidavit of Domestic Partnership should include the names and addresses of both partners, the date the relationship began, a statement of mutual commitment, and details of the financial relationship between the partners. It should also be notarized by a public notary or a lawyer.
