How can i become the executor of a mentally challenged son in order to place him in a safe environment?

Contact a lawyer about having him declared incompetent and then become his legal guardian. Many people believe that just because a child/adult is mentally disabled, he/she is automatically considered incompetent. Not true...he/she can vote, agree to medical procedures, attain credit cards, etc. This can be especially dangerous if someone else takes advantage of the person..ie. running up massive credit card debt in their name, etc. Many parents do not realize they must hire a lawyer and go through the courts to have their son/daughter declared incompetent. This is a good move and protects the person from making bad decisions for themself (unnecessary medial treatments, etc.) or having someone take advantage of them.

probably depends on your state. If you think he's not in a safe environment google the child abuse hotline and call that number. make your report.. that will check it out.. after that if you wanted to take a larger role in their lives you might be able to become their CASA worker (court appointed special advocate) but there are usually lots of people already lined up to do that... best thing you can do is make that phone call.

I missed the son part.. she's right below.

Do you mean become his guardian? You have to file the papers with the courts along with a certificate from his doctor stating that he is mentally not capable of making his own decision.

I truly don't know, but I would recommend counseling with an Attorney from the state in which you live regarding this for the best & most accurate legal advice.
