affecting property previously disposed of by will

A conveyance, settlement or other act of a testator by which an estate in his property, previously disposed of by will, is altered but not wholly divested does not revoke such disposition, but the estate in the property that remains in the testator passes to the beneficiaries pursuant to the disposition. However, any such conveyance, settlement or other act of the testator which is wholly inconsistent with such previous testamentary disposition revokes it.
