Mr. Sarno is licensed to practice law in NJ and NY. His response here is not legal advice and does not create an attorney/ client relationship. The response is in the form of legal education and is intended to provide general information about the matter in question. Many times the questioner may leave out details which would make the reply unsuitable. Mr. Sarno strongly advises the questioner to confer with an attorney in their own state to acquire more information about this issue.
In Florida, one may be adopted as an adult. An adult adotion is as effective as any other. Adult adopton is sometimes used for estate planning purposes. You cannot "un-do" the prior adoption. There is a one-year time limit for contesting an adoption.
Thank God for your relationship with your birth father.
Reversing an adoption is very difficult and I would recommend that you instead consider having your birth father adopt you now. Since you are an adult, this a relatively simple process that only requires your consent, and the consent of your birth father plus notice (not the consent of) to your birthmother and adopted father. This will result in an amendment to your original birth certificate to reflect your birth father as your father. Jeanne T. Tate
