Why Recording Matters
Arizona's deed of trust system relies on public recording to protect everyone involved. Once a deed of trust, trustee substitution, notice of sale, or similar document is recorded with the county recorder, every future buyer, lender, and interested party is treated as if they know what that document says. There is no requirement that anyone actually reads it. Recording alone creates the legal presumption of notice.
A trust deed, substitution of trustee, notice of resignation of trustee, assignment of a beneficial interest under a trust deed, notice of sale, cancellation of notice of sale, trustee's deed, deed of release, and any instrument by which a trust deed is subordinated or waived as to priority, if acknowledged as provided by law, shall from the time of being recorded impart notice of the content to all persons, including subsequent purchasers and encumbrancers for value.
A.R.S. § 33-818This rule is straightforward for most deed of trust instruments. But there is one important exception: assignments of the beneficial interest.
The Assignment Exception
Lenders regularly sell or transfer mortgage loans. When that happens, the beneficial interest under the deed of trust changes hands. Arizona law says that recording such an assignment does not automatically notify the borrower. If the borrower continues making payments to the original lender without knowing about the transfer, those payments still count.
The recording of an assignment of the beneficial interest in a trust deed shall not be deemed notice of such assignment to the trustor, his heirs or personal representatives, so as to invalidate any payment made by them, or any of them, to the person previously holding the note, bond, or other instrument evidencing the contract or contracts secured by the trust deed.
A.R.S. § 33-818This protection matters during estate settlement. If a deceased person's heirs or personal representative continue paying the original lender, those payments are legally valid even if the loan was assigned to a new holder before the borrower passed away.
