The situation that you are describing is called a "step parent" adoption. How easy or complex it is going to be will depend on a number of factors. One of them, however, is whether the children's biologic father is willing to consent to the process. Regardless, your spouse will have to file a petition to adopt the children. You will have to join in that petition. The biological father will have to be served. There will likely have to be a post placement study and report done. If the home study comes back good, and if the bio-father consents, and if all of the notices and forms are properly done, then, a decree of adoption can be entered. Because all of this can get rather complex, particularly if the biological father either doesn't consent or can't be found, my advice would be to hire an adoption attorney.
