How to change Representative Payee of benifits to myself

Hi, I would like to change my Representative Payee which is my father and change it to myself. When i was awarded disability 8 years ago i had a history of drug use and i chose to assign a rep payee because i didn't think it would be wise to assign the check to myself at that time. At this time i am free from drugs for 2 years and am capable of handling money as the circumstances have changed.

How do i go about changing my Rep Payee of my father to myself?
Do i have to go before a judge? I there a form? Is it an easy process?

Can someone here explain this to me?

I have documentation from my mental health provider showing my remission of drugs.

Thanks Again
Chris
