Will is either revoked by destroying the will by Testator or Creating a new Will or making changes in existing Will by a Codicil. A will is liable to be revoked or altered by the maker of it at any time when he is competent to dispose of his property by will. A will is a revocable instrument as distinguished from a Deed.

A will of a living person does not come into operation as when it is executed but only upon his death. It is always revocable so long as the testator is living. Even if the will is expressly to be irrevocable, it can be revoked by the maker of it if the instrument is of a testamentary nature.
