Your question is in the list pool, so, I am continuing on to answer it.
1) Are you and your wife on social security retirement income? If yes, your grandson may be qualify for social security from his relationship with you.
Your child can get benefits if they’re your biological child, adopted child, or dependent stepchild. (Sometimes, your child could also be eligible for benefits on their grandparents’ earnings.) Please look into this aspect. See this website link. https://www.ssa.gov/pubs/EN-05-10085.pdf
To get benefits, a child must have:
A parent who’s disabled or retired and
entitled to Social Security benefits; or
A parent who died after having worked
long enough in a job where they paid Social
None of the grandparents and the grandchild need to be disabled. As long as you are on normal social security retirement, you should look into this aspect.
2) Call the Department of Family and Children Services of your county and find a good social worker. There are many benefits for children and for your family. Find more resources.
3) For social security administration, it seems that your son-in-law does not qualify. If your son-in-law does not qualify, your grandson also does not qualify.
4) Because your grandson's benefit belonging to disability, call the SSA advocacy office for the disabled. They may be able to help.
a.) For the SSA to reopen the case, you should give this office a call. They probably can walk you through all the forms and appeal process. They should also find other possibilities for your grandson.
Still call the appeal and see whether they can reopen the case.
Non-medical reasons, you should contact your local Social Security Office to request the review. You also may call our toll-free number, 1-***-***-****, to request an appeal. People who are deaf or hard of hearing can call our toll-free TTY number, 1-***-***-****.
5) Find an attorney. Retain an attorney to represent you before the SSA and fight them for you. Many disability cases are handled by attorneys. Look for free clinics if you qualify. They can at least help you fight the back payment pay back issue.
Do not sign the bank form until you get an attorney help.
6) This is a fight you cannot and will not give up. This will cost your cash and your money. This is not just the loss of your grandson's benefit. This is asking you to pay cash to the SSA. Don't give up. Once they are successful to claim that you took money you should not have taken. There is no limitation on what is next. This matter is serious.
