We ended up with an agency situation but I started out working on an independent adoption and did quite a bit of research. Your first step is to find a good adoption attorney. You can look on the American Academy of Adoption Attorneys website for one in your area. They will be able to tell you what your next steps should be. You will also need to pay for the expectant mother/parents to have their own attorney.

HTH. Good luck.
