If you are the noncustodial parent and payer of child support who also receives SSDI, your children are also likely receiving a benefit from the Social Security Administration (SSA) based on your disability.  If so, you will receive a credit towards your child support obligation.

For example, if you are court ordered to pay $310.00 a month in child support, but the children already receive a benefit of $320.00 per month from the SSA, you will not likely be obligated to pay any child support.

On the other hand, if you are court ordered to pay $310.00 a month in child support and the children only receive $250.00 per month from the SSA, you will still be obligated to pay the difference between the court ordered obligation and the SSDI award.
