Assignment

Also known as: assignment of mortgage, AOM, assignment of deed of trust, mortgage assignment

An assignment of mortgage is a recorded legal document that transfers a mortgage lien from one holder to another, establishing the new owner's legal standing to enforce the lien, pursue foreclosure, and receive payoff proceeds.

An assignment of mortgage (AOM) is a legal document that transfers a mortgage or deed of trust from one lender (the assignor) to another (the assignee). The assignment is recorded in the county public records where the property is located, making the transfer visible to title companies, courts, borrowers, and other lien holders. In mortgage note investing, ensuring that every assignment in the chain is properly executed and recorded is a foundational requirement for enforcing the lien and protecting your investment.

How the Assignment Fits Into the Loan Transfer

Every secured mortgage loan has two components that must be transferred when the loan changes hands:

ComponentTransfer DocumentPublicly Recorded?Key Requirement
Promissory note (the debt)Allonge / endorsementNoMust match the assignment chain
Mortgage / deed of trust (the lien)Assignment of mortgageYesMust reference the original recorded instrument

The allonge transfers the note — the borrower's promise to pay. The assignment transfers the security instrument — the lien on the property. These two chains must mirror each other. If Company A originated the loan, sold it to Company B, and Company B sold it to you, there should be an allonge from A to B and from B to you, and corresponding assignments following the same path.

What a Recorded Assignment Contains

A properly executed and recorded assignment of mortgage typically includes:

  • Assignor and assignee identified by full legal entity name
  • Reference to the original recorded mortgage by book and page number, recording date, and county
  • Property address and legal description matching the original security instrument
  • Original loan amount as stated in the mortgage
  • Assignor's signature — the assignee does not sign because they are the receiving party
  • Notary block with the notary's seal and signature
  • County recorder's stamp confirming the document has been entered into the public record, including a book and page number and recording date

When reviewing collateral files from a seller, look for the recorder's stamp to confirm each assignment has actually been recorded. Documents in a seller's package may be unrecorded originals. Only documents bearing the county stamp have been entered into the public record.

Why Recording the Assignment Matters

Recording the assignment accomplishes three critical functions:

  1. Establishes legal standing. The public record is the authoritative source for determining who holds a lien on a property. Without a recorded assignment, your ownership of the lien is invisible to courts, title companies, and other parties.

  2. Protects your lien position. If the property is sold, refinanced, or enters foreclosure, county records determine who gets paid and in what order. An unrecorded assignment creates risk that your interest could be overlooked.

  3. Enables future transactions. Whether you are negotiating a loan modification, pursuing a discounted payoff, or selling the note to another investor, a clean chain of title with all assignments properly recorded is a prerequisite.

Failing to record also means you will not receive legal notices — code violations, tax sale proceedings, HOA actions, or payoff requests from title companies all go to the lien holder of record. If that is not you, critical information and payments can pass you by entirely.

The Chain of Assignments

The chain of assignments is the sequential record of every transfer of the mortgage from the original lender to the current holder. Each link in the chain must be unbroken: the assignee on one assignment must match the assignor on the next.

A broken chain of title — where a gap or mismatch exists between assignments — creates serious problems. Courts may question your standing to foreclose. Title companies may refuse to issue policies. Future buyers may decline to purchase the loan. During due diligence, verifying that the assignment chain is complete and recorded is one of the most important checks in the collateral file audit.

Successor-by-Merger Language

Sometimes the chain appears to have a gap that is actually explained by a bank merger or acquisition. If National City Bank originated a loan and was later acquired by PNC Bank, then PNC can assign the loan by referencing the merger: "PNC Bank, successor by merger to National City Bank." This SBM language bridges what would otherwise look like a broken chain and is legitimate provided the merger actually occurred.

How to Record an Assignment

There are two recording methods:

E-recording uses specialized vendors (such as CSC or Simplifile) to submit documents electronically. Assignments are typically recorded within 24 to 48 hours. Not all counties accept e-recording, so confirm availability before submitting.

Mail-in recording works with every county. You mail the original assignment, a check for the recording fee, and a self-addressed stamped envelope to the county recorder's office. Turnaround is typically 30 to 60 days, though the county will process the document into the public record well before mailing the original back.

Before submitting, call the county recorder's office to confirm formatting requirements — font size, margin widths, paper size, and fee amounts vary by county. A brief phone call can prevent a rejection that adds weeks of delay.

Corrective Assignments

A corrective assignment is filed when a previously recorded assignment contains an error — an incorrect entity name, a wrong legal description, or other inaccurate information. It adds another document to the chain to fix the record. If an assignment has not yet been recorded (for example, it was rejected and returned), you simply correct the original document and resubmit rather than filing a corrective assignment.

Recording as a Post-Closing Priority

Recording the assignment of mortgage from the seller to your entity should be one of the first actions after closing on a loan purchase. Until the assignment is recorded, the public record does not reflect you as the current lien holder — and your legal rights are correspondingly weaker. Experienced note investors treat assignment recording as a non-negotiable post-closing step, not an administrative afterthought.
