An affidavit proof of residence is a legal document that is used to certify that an individual is currently living at a given address. It must be signed and notarized by both the individual who is providing the proof of residence and the person witnessing the signature. This document can be used as part of a court case or other legal proceeding, or it may be required by an organization or governmental agency. The affiant—the person certifying the residence—must have personal knowledge that the individual lives at the given address and must provide their name, address, contact information, and signature in order for the affidavit to be valid.
