My son wants to go to college and his dad was killed in accident and he receives death benefit . is there any help for him in college tuition?

Hi,

Not from Social Security. Social Security child benefits end at age 18 unless the child is disabled or still in high school.
If a child is still in high school when they reach age 18, their benefits can continue until the earlier of a) when they graduate from high school or b) reach age 19.

The only way that your son's benefits could continue to be paid while he's in college is if he's disabled and qualifies for disabled adult child's benefits. My expertise is limited to Social Security, so I don't know whether or not there are any other possible sources of tuition help for your son.

Best, Jerry
