Marriage certificate is must

@olu what do u mean u don’t have their marriage certificate? did they marry? if they are together and never married u can organize a legal marriage for them so that they get marriage certificate cause u need it to prove they married

they got married traditionally over 40 years ago and there marriage was never registered

@olu then let’s them try marry again like legal marriage, it’s easy depending on which country u from. city clerks do that

do they have to be married to quality? or is just proof that they are your unmarried biological parents enough? I.e. from birth certificate
