An Affidavit of Non Re-Marriage Certificate is a sworn legal document in which a person formally declares that they have not remarried following the death of their spouse. This affidavit serves as official proof that the individual remains a widow or widower and has not entered into another marriage. Since it is a sworn statement, it must be signed in the presence of a notary public or another authorized official. Providing false information in an affidavit is a serious offense and may lead to legal consequences, so the declaration must be accurate and truthful.
