In New York, adoptive parents generally cannot unilaterally annul an adoption after the adoptee reaches legal age; reversal is only possible in very limited circumstances, and it requires a court process with strong legal grounds.
Under New York law, a finalized adoption is a permanent legal parent–child relationship. Once the adoptee turns 18, the adoptive parents do not have the right to simply cancel the adoption. The only way to reverse it is through a court petition in the same court that granted the original adoption. A finalized adoption, is considered a permanent legal judgment.
In New York, adoptive parents cannot unilaterally annul an adoption after the adoptee turns 18. The adoptee must petition the court, and success depends on proving a legal ground for reversal. Without such grounds, the adoption remains in effect indefinitely.
