​RESIDUE (through the French, from the Lat. residuum, a remainder, from residere, to remain), in law, that which remains of a testator's estate after all debts and legacies are discharged, and funeral, administration and other expenses paid. The person to whom this residue or surplus is left is termed the residuary legatee; should none be mentioned in the will the residue goes to the next of kin (see Executors and Administrators; Legacy; Will).
