A will is the testament of the testator. It is a posthumous disposition of the estate of the testator directing the distribution of his estate upon his death. It is not a transfer inter vivos. The two essential characteristics of a will are that it is intended to come into effect only after the death of the testator and is revocable at any time during the lifetime of the testator. It is said that so long as the testator is alive, a will is not worth the paper on which it is written, as the testator can at any time revoke it. If the testator, who is not married, marries after making the will, by operation of law, the will stands revoked. Registration of a will does not make it any more effective. Shiv Kumar v. Union of India, (2019) 10 SCC 229.
