Father Estopped from Denying Paternity—Best Interests of Child Prevail

In upholding Family Court’s determination the father was estopped from denying paternity, in spite of his executing the acknowledgment based upon a mistake of fact, the Second Department explained the relevant legal principles:

A party seeking to challenge an acknowledgment of paternity more than 60 days after its execution must prove that it was signed by reason of fraud, duress, or material mistake of fact (see Family Ct Act § 516-a[b][ii]). If the petitioner meets this burden, the court is required to conduct a further inquiry to determine whether the petitioner should be estopped, in accordance with the child’s best interests, from challenging paternity…. If the court concludes that estoppel is not warranted, the court is required to order genetic marker tests or DNA tests for the determination of paternity, and to vacate the acknowledgment of paternity in the event that the individual who executed the document is not the child’s father (see Family Ct Act § 516-a[b][ii];…). * * *

The purpose of equitable estoppel “is to prevent someone from enforcing rights that would work injustice on the person against whom enforcement is sought and who, while justifiably relying on the opposing party’s actions, has been misled into a detrimental change of position” …. Thus, “a man who has held himself out to be the father of a child, so that a parent-child relationship developed between the two, may be estopped from denying paternity,” in light of the child’s justifiable reliance upon such representations, and the resulting harm that his denial of paternity would engender…. “The doctrine in this way protects the status interests of a child in an already recognized and operative parent-child relationship” …. In all cases, “the doctrine of equitable estoppel will be applied only where its use furthers the best interests of the child” … . Matter of Angelo AR v Tenisha NW, 2013 NY Slip Op 05084, 2nd Dept 7-3-13
