What if we share custody? Can I still receive child support?

It depends.  Pennsylvania's support guidelines are based on the Income Shares Model, and supports the concept that children of separated parents should receive the same amount of support they would if their parents were together.  The numbers are calculated based on the parties' respective net incomes, taking into consideration any deviations allowed under the guidelines. Consideration of how much time each parent has with the children, specifically overnight time, will also be factored into the guideline calculation.
