A civil marriage is a marriage that is performed, recorded, and recognized by a government official. It can be performed by a religious body and recognized by the state, or it can be entirely secular. The ceremony is nonreligious and is officiated by a legal official, and the marriage is recognized as a legal union. Civil marriages require a certificate and, at times, a license that testify that the couple is fit for marriage. The requirements for a civil wedding ceremony typically include a photo ID, birth certificate, and proof of citizenship or passport
