This helps eliminate many legal problems that arise in an intestate's estate. A Testator is also able to nominate guardians in the will to care for minor children. The will may also bring about the benefit of tax advantages both for the devisees and the estate taxes. In order for a will to be legal, you must have two witnesses along with the notary public and the testator in the same room at the time the will is to be signed. In Louisiana, Maine, Massachusetts, New Hampshire, South Carolina, and Vermont you need three witnesses present.
Beneficiaries are unable to be witnesses.
If a beneficiary is a witness to the will, the will is void. If is very simple. A will is revocable up until the testator's death. The testator can simply destroy the will by means of burning or tearing it up. That will begin the probate process.
