In a support matter, the incomes of the parties will be used to calculate an appropriate award based on the support guidelines applicable throughout the Commonwealth. At the initial appearance for a support matter, both parties are asked to bring in proof of their income in the form of W-2s, tax returns, pay stubs, or other documentation of income received. If a party is unemployed or underemployed, the courts may consider their earning capacity. Pennsylvania Rule of Civil Procedure 1910.16-2(d)(4) discusses earning capacity. First, the rule indicates there should be a determination that a party willfully failed to obtain or maintain appropriate employment. Involuntary reductions income (e.g. lay-offs or unemployment due to illness or disability) generally do not trigger an earning capacity analysis.
