There is no requirement that a will be witnessed by anyone at the time of execution. However, after the death of the testator, two witnesses, either subscribing witnesses or non-subscribing witnesses, must verify the signature on the document as the signature of the testator. A will witnessed by subscribing witnesses at the time of execution can better survive a will contest because the testator's legal capacity to make a will can be verified more easily. Wills can be made self-proving if the testator and two subscribing witnesses sign proper acknowledgements at the time of execution. A self-proving will eliminates the necessity for witnesses to prove the execution of the will after the death of the decedent.
