A person who has signed an Affidavit of Parentage claiming to be the parent of a child may rescind (cancel) the Affidavit by completing a Rescission Form for Affidavit of Parentage and signing and dating it in the presence of a notary public within 60 days of the date the Affidavit was signed by both parties. If more than 60 days have passed from the date the Affidavit was signed, the Rescission Form will NOT rescind the Affidavit. If the Parents signed on different dates, count from the date that the last parent signed.
After the expiration of the 60 day period, the Affidavit can only be nullified by a court order, upon a finding of fraud, duress or material mistake of fact.
You may obtain a Rescission Form by calling the Maryland Department of Health/Division of Vital Records at 410-764-3038.
