OVERPLUS. What is left beyond a certain amount; the residue, the remainder of a thing. The same as Surplus. (q. v.)

2. The overplus may be certain or uncertain. It is certain, for example, when an estate is worth three thousand dollars, and the owner asserts it to be so in his will, and devises of the proceeds one thousand dollars to A, one thousand dollars to B, and the overplus to C, and in consequence of the deterioration of the estate, or from some other cause, it sells for less than three thousand dollars, each of the legatees A, B and C shall take one third: the overplus is uncertain where, for example, a testator does not know the value of his estate, and gives various legacies and the overplus to another legatee; the latter will be entitled only to what may be left. 18 Ves. 466. See Residue; Surplus.
