State laws vary regarding notarization of trusts. New York require that two witnesses -- or a notary -- sign a trust. In Florida, not every type of trust must be in writing, but a revocable trust that transfers property outside of your estate after your death must be signed with the same formalities as a will -- two witnesses and a notary. In other states, two witnesses must sign, but one can also act as the notary public. Regardless of state requirements, it's a good idea to have a notary witness your signature on trust documents because her seal speaks to the authenticity of your signature after your death.
Why Sign a Trust
People create trusts for a variety of reasons, but primarily because a trust can save your heirs the cost and time required to probate your will and may reduce taxes on your estate. A trust also allows you to control how your assets are distributed after your death and provides protection against creditors and lawsuits. Trusts fall into two broad categories: revocable and irrevocable. Generally, you can make changes to a revocable trust, but not an irrevocable trust.
