A paying parent who receives Supplemental Security Income (SSI) cannot be ordered to pay child support out of their SSI income. But a paying parent who receives Social Security Disability (SSDI) can be ordered to pay child support out of their SSDI income.

If a paying parent gets SSDI, the child may be eligible for a Social Security dependent benefit on the paying parent's Social Security record. This dependent benefit will usually count toward the paying parent's child support payment.
