Pennsylvania Exceptions to Recommendation of Custody Master (PERCY) are an exception to the state’s general rule that a Custody Master’s recommendation is binding when it comes to determining the terms of custody and visitation. Under Pennsylvania law, a court may reject or modify the Custody Master’s recommendation under certain circumstances. The three types of Pennsylvania Exceptions to Recommendation of Custody Master are: 1) the Master's recommendation is not in the best interest of the child; 2) the parties did not receive proper notice of the proceedings; or 3) the Master's recommendation is not supported by the evidence. In order for the court to reject or modify the Master’s recommendation, it must make specific findings that the Master’s recommendation is not in the best interest of the child, or that the parties did not receive proper notice of the proceedings. The court must also consider the evidence presented at the Master’s hearing, and must review the Master’s findings before making a decision. The court may reject or modify the Master’s recommendation if the court determines that it is not in the best interest of the child or that the parties did not receive proper notice of the proceedings. The court may also modify the Master’s recommendation if it finds that the recommendation is not supported by the evidence.
