If a trust agreement is created and you cannot find the original document is the trust valid with the signed but not notarized copies?

You have a problem if the original trustor is deceased and the trust was used to remove property from their estate, especially if the trust holds real estate or valuable personal property such as insurance policies, investment accounts and bank accounts. You may need to bring the matter to court and get a court order that validates the unacknowledged copy. This is a good reason to record trusts in the land records. You need to consult with an attorney who can review your situation and determine your options under your state laws.
