Legal Question in Family Law in Louisiana

There needs to be more basis than rehab to terminate a parent's rights.

Maybe, but I doubt it. Look at the Louisiana Children's Code Article 1015 for grounds for termination. In an intrafamily adoption, if the parent has not paid support or visited with his child for a period in excess of 6 months, then their permission to the adoption may not be required. There is NO grounds for termination based on entering rehabilitation.
