Hi, and thank you.
I know you are finding references to a need to have witnesses and notary, but I am not finding that under the law. In fact, a writing isn't even always necessary, if manifestation of the settlor's intent is clear:
Here is another attorney, Attorney Gruber, who seems to reiterate my thoughts on this and understanding of the probate
code on trusts:"Witnesses are not needed for a living trust, which is usually notarized. Notarization is not required for a trust, but it is a good idea because it provides proof that the trustor signed the trust.
Now, on the other hand, if you have reason to believe your father did not sign that trust, that would be a basis on which to fight its validity as his trust document, and you would want, possibly, a handwriting expert to testify that that signature is not your father's, based on undisputed copies of his signature on prior documents.
I hope this helps clarify for you.
