I think through the Regional Centers there are attorneys that deal specifically with these issues. I pray it works out for the child & family...

In Califoria there is. Court Appointed Special Adovocate Program. I'll. Check it out and share findings.

Every situation is unique and there are individuals who specializes depending on what kind of disability the child has. Sounds like you need a Law Guardian - at least that what they are called here in NY, that has special needs cases background. I found a site that might be helpful: http://www.education-a-must.com/advocates.html#CO

Or they under the CA section can at least point you in the right direction, the worst they can say is "Sorry I don't know." Others may even give you a name and contact info.

A guardian ad litem should be appointed to tell the best interest of the child to the court. They may or may not have experience with special needs.
Other than that reports from other professionals, an documentation of the positive situation need to be brought to court. There are educational advocates for special needs some specific to autism, but I have never heard of anything similar for custody/court issues. An understanding guardian ad litem is what is needed.

Thanks guys!! I will pass everything on to the family and they really are greatful.
