In order for a Will to be valid, it must be signed by the person making it (ie testator) in the presence of at least two Witnesses and the Witnesses must sign in the presence of the Testator. It is not necessary that the Witness should know the content of the Will since they are only testifying to the signature of the testator. A legatee under a Will cannot be a Witness. If a legatee is also a Witness, he will not be entitled to that asset under the Will. In addition, for a Christian or a Parsee, an Executor also cannot be a Witness.
