Codicil

3 A supplement to a will, or an addition made by the testator, annexed to, and to be taken as part of, a testament: being for its explanation, or alteration, or to make some addition to, or else some subtraction from, the former disposition of the testator.* A clause added to a will after its execution; the purpose of which usually is to alter, enlarge, or restrain the provisions of the will, or to explain, confirm, and republish it.' Part of the will, to be construed with it, as one entire instrument... But the will is not altered by the codicil, except by express words or necessary implication. It is to be deemed altered by necessary implication where a subsequent provision is inconsistent with and repugnant to a prior provision. But where they can stand together, both shall have effect. ^ The effect of republication of the will by the addition of a codicil is to bring both instruments to the same date.'
