Paternity Acknowledgment
Notice Written or Oral
After downloading this form, and before you complete it, you must read the entire form and/or receive oral notice of the above information. This notice may be obtained over the telephone by calling (888) 570-9906.
Denying Paternity
If the mother was married and the husband is not the natural father of the child, a completed Affidavit Denying Paternity is required. This document must be signed in front of a Notary Public.
The Affidavit Denying Paternity submission must also include an Affidavit Acknowledging Paternity from the natural father as both Affidavits are required to establish correct parentage.
Paternity Denial
I have already signed an Affidavit Acknowledging Paternity, but I am not the natural father.
If you have already signed an Affidavit Acknowledging Paternity indicating you are the natural father, you must now obtain a court order to deny paternity.
Who should not sign an affidavit acknowledging paternity
The Affidavit Acknowledging Paternity is used to legally establish who the father of a child is when the birth mother and biological father are not married to one another. This affidavit is a legal document. Signing this form is voluntary. A correctly completed affidavit has the same effect as a court order establishing paternity. If you do not understand the legal consequences of signing this form, you may want to consult an attorney.
For an adult child
If you are an adult child over the age of 18 and do not a have a father listed on your birth certificate, you may add your natural father by using the Affidavit Acknowledging Paternity – Part II below, as well as providing the Affidavit Acknowledging Paternity signed by both parents. If both forms are unable to be completed a court order is required.
