Hi. Adoptions are typically final. This is especially true in the case of true relinquishment as opposed to a contested termination of parental rights. However, the rights of a parent to their child are quite strong in the United States and so it is possible that your daughter could pursue an Order to set aside the prior proceedings for technical/procedural reasons. These message boards can be helpful but nothing will replace an in-person meeting to review your situation in particular. Please feel free to contact our office and schedule a no-cost interview/assessment to discuss your matter in greater detail.
