You'll need this document to prove your cohabitation status to various institutions, government agencies, and legal entities that require verification of your shared living arrangement.

When do you need this document?

You'll typically need an Affidavit Of Cohabitation when applying for domestic partner benefits through your employer, seeking immigration benefits for your partner, or establishing legal rights in states that recognize common law marriage.
