On December 29, 2015, the Pennsylvania Supreme Court decided that a step-parent can be responsible for child support if that step-parent has taken aggressive legal steps to obtain the same custodial rights as a biological parent. A.S. v. I.S., No. 8 MAP 2015 (Pa. Dec. 9, 2015). The mere existence of a relationship between the step-parent and child and other reasonable acts to maintain a post-separation relationship with stepchildren remainsufficient to establish a duty to pay child support. Id. citing Commonwealth ex rel. McNutt v. McNutt, 344 Pa. Super. 321 (1985).
