Under certain circumstances, some other family members may be eligible. A stepchild, grandchild, step-grandchild, or adopted child could be eligible for the benefits.
How can I return the monthly benefits received after the death of a family member?
It depends on the benefits the deceased was receiving. If he was getting the funds by direct deposit you should contact the bank or other financial institute. And if the benefits are received by check, you must return the check to Social Security as soon as possible.
