1. The multiplicity of wills is not deemed a revocation of the previous will unless the testator expressly declares his/her revocation thereof, and any interested party may prove its revocation. 2. If there are multiple wills, without specifying the bequeathed property and the insufficiency of the one-third, then the deficiency is proportionally imposed on all the devisees in accordance with his/her share. If the bequeathed property is specified, it shall be divided equally among all the devisees, unless variance is stipulated by the testator.
