Is it constitutional for a testator to direct that grandchildren are disinherited if they marry outside a designated religion? "Because a testator or the settlor of a trust is not a state actor, there are no constitutional dimensions to his choice of beneficiaries. Equal protection does not require that all children be treated equally; due process does not require notice of conditions precedent to potential beneficiaries; and the free exercise clause does not require a grandparent to treat grandchildren who reject his religious beliefs and customs in the same manner as he treats those who conform to his traditions."
