Thank you for your patience.
So an unrecorded deed that is valid still has legal effect as to the parties that have actual or constructive notice. The purpose of the recording requirement is to protect good faith purchasers when relying upon recorded documents in the chain of title. So failing to record the deed does not void the deed as between the contracting parties.
A deed can be voided/rescinded if certain facts exist. The grounds for voiding a deed are as follows:
1. undue influence - a party unduly influences (ie manipulates) another, inducing that party to transfer the deed
2. breach of fiduciary duty- the parties have a certain relationship whereby one party owes the other a fiduciary duty -ie power of attorney, husband and wife, etc.
3. mistake - this requires either a mutual mistake of fact, or fraud - Cummings's Case, 52 Mass. App. Ct, 444 (2001)
If the idea is to return it to a particular estate and the transferee indicates that will occur, then they use their position as trustee of that estate to transfer the property out, the deed can be rescinded based on fraud. Additionally, if the transaction goes through and the trustee transfers property from the estate to their own estate, that is considered a breach of fiduciary duty, breach of trust, and possibly undue influence. A trustee is prohibited from self dealing.
