Rule 1910.16-1 Support Obligation. Support Guidelines

Chapter 1910: Actions for Support

(a) Applicability of the Support Guidelines.

(1) Except as provided in subdivision (a)(3), the support guidelines determine a spouse’s or parent’s support obligation based on the parties’ combined monthly net income, as defined in Pa.R.Civ.P. 1910.16-2, and the number of persons being supported.

(2) If a person caring for or having custody of a minor child, who does not have a duty of support to the minor child, initiates a child support action as provided in Pa.R.Civ.P. 1910.3:

(i) the complaint shall name the parents as defendants;

(ii) in determining the basic child support obligation, the monthly net income for the individual initiating the action shall not be considered in the support calculation by the trier-of-fact;

(iii) the parents’ monthly net incomes shall be combined to determine the basic child support obligation, which shall be apportioned based on the parents’ respective monthly net incomes consistent with Pa.R.Civ.P. 1910.16-4. The parents shall pay the obligee their proportionate share of the basic child support obligation as a separate obligor; and

(iv) as with other support actions, the trier-of-fact may adjust or deviate the basic child support, spousal support, or alimony pendente lite obligation consistent with the support guidelines based on the evidence presented by the parties.

(3) In an action in which the plaintiff is a public body or private agency pursuant to Pa.R.Civ.P. 1910.3, the basic child support obligation shall be calculated under the guidelines based upon the parent’s monthly net income with the public or private entity’s monthly net income as zero. In such cases, each parent shall be treated as a separate obligor, and the parent’s obligation will be based upon the parent’s monthly net income without regard to the other parent’s monthly net income.

(i) The basic child support obligation owed to a child not in placement shall be deducted from each parent’s monthly net income before calculating support for the child in placement, including the direct support the support guidelines assume the custodial parent will provide.

(ii) If the parents reside in the same household, each parent’s respective basic child support obligation to a child that remains in the household and is not in placement shall be calculated according to the guidelines, with the parent having the higher income as the obligor, and the calculated basic child support obligation shall be deducted from the parents’ monthly net incomes for purposes of calculating support for a child in placement.

(iii) If the basic child support obligation exceeds the placement’s cost, the trier-of-fact shall:

(A) deviate the basic child support obligation downward; and

(B) apply the parent’s percentage of the combined monthly net income to the reduced basic child support obligation.

(4) The support of a spouse or child is a priority obligation so that a party is expected to meet this obligation by adjusting the party’s other expenditures.

(b) Support Obligation. The support obligation (child support, spousal support, or alimony pendente lite) awarded pursuant to the Pa.R.Civ.P. 1910.11 and 1910.12 procedures shall be determined in accordance with the support guidelines, which consist of the guidelines expressed as the basic child support schedule in Pa.R.Civ.P. 1910.16-3, the Pa.R.Civ.P. 1910.16-4 formulas, and the operation of the support guidelines as set forth in these rules.

(c) Spousal Support and Alimony Pendente Lite.

(1) Spousal support and alimony pendente lite orders shall not be in effect simultaneously.

(2) In determining a spousal support or alimony pendente lite obligation’s duration, the trier-of-fact shall consider the marriage’s duration, i.e., the date of marriage to the date of final separation.

(d) Rebuttable Presumption. If the trier-of-fact determines that a party has a duty to pay support, there is a rebuttable presumption that the guideline-calculated support obligation is the correct support obligation.

(1) The presumption is rebutted if the trier-of-fact concludes in a written finding or states on the record that the guideline support obligation is unjust or inappropriate.

(2) The trier-of-fact shall consider the child’s and parties’ special needs and obligations, and apply the Pa.R.Civ.P. 1910.16-5 deviation factors, as appropriate.

(e) Support Guidelines Review. The support guidelines shall be reviewed at least every four years to ensure that their application determines the appropriate support obligation.
