The Orphans’ Court approved the modification of a testamentary trust for the benefit of the settlor’s son in order to allow distributions of principal for the medical expenses and support of the settlor’s son, the court finding that the settlor could not have anticipated that his son would live to age 99, or the advances in medical care and the resulting costs of that care that would occur in the 55 years after the settlor’s death, or that the trust created by the settlor’s wife would be exhausted by distributions for the support of their son.
