An intestate heir who does not join in an appeal from the probate of a will has no standing to challenge a settlement agreement between the beneficiary under the will and the other intestate heirs which left the probate of the will intact and required the beneficiary to make payments to the intestate heirs who had appealed from probate. Estate of Anne W. Ballinger, No. 545 AP of 2013 (Philadelphia O.C. 11/9/2016), on appeal, 2620 EDA 2016 (Pa. Super.).
