What is the name of your state (only U.S. law)? Massachusetts I recently got approved for SSI Disability payments and for payments for my minor soon as well based on my past work history. When I became disable (2 years ago) my son who is now 16 went to live with his dad on a fully time basis since I could not care of him and he prefered to go to school in the town where his dad lives. Prior to this, I had full custody of my son and he saw his dad every other weekend. I get my benefit and a benefit for my son. My son now lives during the summer with me half of the time and half of the time with his dad. By law, do I have to give his dad any of my son's benefit?? I have it put aside for my son for college and for whatever else he needs. If I have to pay some sort of child support, I understand, but what is the child support payment based on? If I were to give his dad the entire benefit that my son receives, it would be spent on my ex husband supporting his mother as well. I dont believe my son's benefit should have to pay for my former mother in law in any way....please help....Frustrated in Boston. Thank youWhat is the name of your state (only U.S. law)?
