In this work, some properties of supplement elements in lattices are investigated. Some relation between lying above and (weak) supplement elements also studied. Some properties of supplement submodules in modules which given in [8] are generalized to lattices. Let a be a supplement of b in a lattice L. If a/0 has at least one maximal (not equal a) element, then it is possible to define a bijective map between the maximal elements (not equal a) of a/0 and the maximal elements (not equal 1) of 1/b. Let a be a supplement element in a lattice L. If L is amply supplemented, then a/0 is also amply supplemented. If L is weakly supplemented, then a/0 is also weakly supplemented.
