My husband and I are wanting to try and get custody of his 5 year old son. We did not know about this child until he was 1 1/2 years old. We were married and living in Iowa, as we currently do and mom lives in Illinois. Paternity was established through the courts and child support set up but we never took it for visitation or custody rights at the time because mom was moving to California with her new husband. This was in 2006. She was not in CA for long when she moved back to Illinois and in with another man. Since then we have seen my stepson but not on a regular basis since we live so far away. I would say it's been at least every few months. Mom has had different boyfriends and moved several times in the past couple of years. We just recently began visiting my stepson once a month but still have nothing in the courts. We were just informed today that mom was arrested for driving under the influence of drugs last week and admitted herself into drug rehab and could be there for up to a year. How do we get custody of my stepson while she is in rehab? Will we have to have a lawyer to do so? Once we have temporary custody will he automatically go to mom after she is out of rehab? If we fought for full custody would we have a chance or would not seeing him regularly hurt us? Any advice on how to handle this would be good.
