Benefits payable to the children can affect the child support award. Pennsylvania Rule of Civil Procedure 1910.16-2(b) discusses the treatment of public assistance, SSI benefits, certain Social Security payments and foster care payments in regard to calculation of support. Per sub-section (1) public assistance and SSI payments cannot be considered. SSI is a federal means-tested benefit. It operates as more of a welfare benefit similar to public assistance. Examples of public assistance include cash assistance or food stamps. Sub-section (2) addresses social security derivative payments for children. Any social security benefit as a result of a parent's death, disability or retirement should be addressed in the child support calculation. It should be added to the income of the party receiving the benefit.
