In certain countries, a certificate of no impediment to marriage is required for a marriage abroad. The certificate of no impediment to marriage certifies that there are no impediments to marriage under German law. This is issued by the registry office of the main or secondary residence of one of the two engaged couples. If there is neither a residence nor a domicile in Germany, the registry office of the last place of residence is responsible for issuing the certificate of no impediment to marriage.
