1. I have the actual care and custody of minor child. This is an article that outlines how to fill out the forms but let's just do it together.My son's father lied on an affidavit about me to get temporary custody of our son. If I can prove it in court, will the case get thrown out? An affidavit of marriage is a legal document and a sworn statement submitted to the court or another institution, to verify that two people are married. If the probate registrar determines the application is complete, the registrar will issue a statement of probate and appoint a personal representative. This is probably a scam.
