It is impossible to reverse a legally complete adoption. However, the laws of most states allow the birth mother a chance at reclamation for a definite period following the baby's birth. The mother can reject the adoption even after signing the formal paperwork for giving away parental rights to her kid.n2. The birth mother has 48 hours (for reclamation) after signing the legal adoption paperwork in some states, while it's 30 days in others. In a few places, the birth mother doesn't have the option to change her decision. Rest assured that the attorney will inform both the birth mother and adoptive parent about the time frames for such modifications.n3. For an adoptive family, this can be a difficult moment. After placing a child for adoption and going through the adoption procedure, the concept that a birth mother can withdraw consent to the adoption may feel unfair. Adoption regulations are in place to safeguard everyone involved, even if they vary significantly from state to state. n4. The biological parent of the child has the freedom to reclaim them. But it's not always that they do it. The adoption agencies screen such parents before letting the kid be adopted. However, there are some situations where this does happen, and you may have to give your kid back to their biological parents. Though this would be sad for you if it happens, you have no choice but to accept it and let go of your child.
