Home visit: Expect a home visit from a DFPS caseworker to review your personal history, lifestyle, experience caring for children and many other factors designed to determine whether you are an appropriate candidate for adoption. Each member of your household, including other children, will be interviewed, so that a complete picture of the prospective family unit can be developed.
Adoption attorneys or adoption law firms are best for prospective birth mothers who have already identified an adoptive family and who feel they don’t need much adoption counseling and support. It is important to carefully consider the resources and services you’d like to have available before choosing an adoption attorney as your adoption professional.
In MO, where I live the legal age of adulthood is 17. Some states it is 17, some 18. If I were you I would check into that. If legal age in your state is 17, I would just wait a few months and do an adult adoption. Then you would not need anyone's consent other than yours, your husband's and your (now adult) daughter. Then you could complete your adoption without stirring up a hornets nest, although if your daughter is interested in meeting her birthparents....this would be the perfect opportunity to make that happen.
