Can I use this form?

To use this form, the following must be true:

  • You signed a VAP because of fraud, duress, or material mistake of fact and you want to undo it,
  • The VAP was filed with the Illinois Department of Healthcare and Family Services OR, if the VAP was filed in another state, the other parent who signed the VAP lives in Illinois, and
  • The deadline for you to cancel the VAP outside of court has passed. You usually have 60 days from the VAP effective date to rescind it, but the deadline may be shorter. If you are within the timeframe to rescind the VAP, you should rescind the VAP outside of court instead of bringing a court case. 

Learn more about the voluntary acknowledge of parentage (VAP) form.

  • The date the VAP and Denial of Parentage (if applicable) were filed with the Illinois Department of Healthcare and Family Services, and
