Sec. 11.

(1) The mother or the man who signed the acknowledgment, the child who is the subject of the acknowledgment, or a prosecuting attorney may file a claim for revocation of an acknowledgment of parentage. If filed as an original action, the claim shall be filed in the circuit court of the county where either the mother or man resides. If neither of those parties lives in this state, the claim shall be filed in the county where the child resides. A claim for revocation may be filed as a motion in an existing action for child support, custody, or parenting time in the county where the action is and all provisions in this act apply as if it were an original action.

(2) A claim for revocation shall be supported by an affidavit signed by the claimant setting forth facts that constitute 1 of the following:

(a) Mistake of fact.

(b) Newly discovered evidence that by due diligence could not have been found before the acknowledgment was signed.

(c) Fraud.

(d) Misrepresentation or misconduct.

(e) Duress in signing the acknowledgment.

(3) If the court finds that the affidavit is sufficient, the court may order blood or genetic tests at the expense of the claimant, or may take other action the court considers appropriate. The party filing the claim for revocation has the burden of proving, by clear and convincing evidence, that the man is not the father and that, considering the equities of the case, revocation of the acknowledgment is proper.

(4) A copy of the order of revocation shall be forwarded by the clerk of the court to the state registrar. The state registrar shall vacate the acknowledgment and may amend the birth certificate as prescribed by the order of revocation.

(5) Whether the claim for revocation under this act arises as an original action or as a motion in another action, the prosecuting attorney, an attorney appointed by the county, or an attorney appointed by the court is not required to represent either party regarding the claim for revocation.
