How can I redirect social security payments?

Hi! I recently obtained temporary legal custody of my god son (8 yo). He receives ss payments and I was told by cps that I need to have his payments redirected to myself and my husband. I’ve never had to deal with anything social security before so I was wondering if anyone knows the process for redirecting payments??

I would assume you go to the as office and bring his social, birth certificate and papers showing you have custody.
