My personal choice for a trust is a "Common-law, Irrevocable, Non-Statutory, Pure Trust". none other.
If anyone suggests a notary signature or "filing" for such a trust - forget about it, and look ELSEWHERE. Just as I KNOW FOR SURE the person who goes by the name of "Paul" in Texas does. Which means he is sadly MISTAKEN. The fact is.... notarizing a document instantly gives the trust jurisdiction, RENDERING it STATUTORY.
