Is there any one who knows how I am able adopt my fiancés 5 year old son. His father is not in the picture at all and his name is not on the birth certificate at all. We are planning on getting married soon but we wanted to find out if there is a way to get the adoption process rolling ahead of time.

Most states require that you be married for a period. You will also need to get the bio father to relinquish his rights. For all of this you really should get an attorney. You can start shopping for one now. In doing so you should learn the requirements and when you can file.
