Can a mother change her mind after father signs away parental rights in NY?

In New York, once a father voluntarily signs away his parental rights, that decision is generally permanent and cannot be undone unilaterally. However, a mother may seek to change arrangements, such as custody or visitation, through the court if circumstances have changed. The court will consider the best interests of the child in any new proceedings. It's advisable to consult a family law attorney for specific guidance in such situations.
