No. The law does not require eyewitnesses (subscribing witnesses) to the signature of the testator in order for the Will to be valid. However, it is the custom to have two (2) subscribing witnesses present since at the time of probate, two (2) witnesses, subscribing or non-subscribing, must appear and identify under oath the signature of the decedent on the Will. Wills can be made self-proven if proper acknowledgements and affidavits are signed by the testator and witnesses at the time of execution. Self-proving Wills eliminate the need for the witnesses appearing at the Register’s office.
