Where real property, subject to a mortgage executed by any ancestor or testator, or subject to any other charge, including a lien for unpaid purchase money, descends to a distributee, or passes to a devisee, such distributee or devisee must satisfy and discharge the mortgage or other charge out of his own property, without resorting to the executor or administrator of his ancestor or testator, unless there be an express direction in the will of such testator, that such mortgage or other charge be otherwise paid.
