Establishing paternity has many benefits outside child support, but proof of paternity is required to receive those benefits. Many of the benefits only come into play in the event of the father’s death, therefore you shouldn’t delay establishing legal fatherhood.
Social Security Benefits
Paternity must be established for a child to receive a Social Security benefit if a father dies before the child has attained age 18. Children are generally eligible for Social Security benefits if they are under 18 or under 19 and are enrolled in elementary, intermediate, or secondary school full time.
