In 2019, an important case was decided by the Pennsylvania Superior Court. That case was RL v. MA, 209 A.3d 391 (Pa. Super. 2019). The RL case pertained to a custody dispute between a same-sex couple. In Pennsylvania's Child Custody Act, there is only one presumption. That presumption is under Section 5327, which is titled: "Presumption in Cases Concerning Primary Physical Custody." Under subsection "b" of that Section titled: "Between a Parent and Third Party," it reads: "in any action regarding the custody of a child between a parent of the child and a nonparent, there shall be a presumption that custody shall be awarded to the parent. The presumption in favor of the parent may be rebutted by clear and convincing evidence." In the RL case, the nonbiological mother was seeking equal physical custody of the child.
