What is a Mortgage and a Deed of Trust?

Mortgages and Deeds of Trust are legal instruments used in real estate transactions to secure a loan with property as collateral. They establish the borrower’s obligation to repay the loan and grant the lender certain rights over the property in case of default. While they serve similar purposes, the two documents function differently depending on state laws and lending practices.

What is a Mortgage?

A mortgage is a legal agreement between a borrower (mortgagor) and a lender (mortgagee) in which the borrower pledges their property as security for a loan. The borrower retains ownership of the property while making payments, and the lender has the right to foreclose if the borrower defaults on the loan.

Key Features of a Mortgage

  • Two Parties Involved: The borrower and the lender.
  • Who holds title: The borrower keeps ownership and stays in possession. Whether the mortgage is treated as a lien against the property or as a conveyance of legal title depends on whether the state follows lien theory or title theory, which is a separate question from which instrument the state uses.
  • Foreclosure Process: Set by state law. Where the mortgage carries no power of sale, the lender forecloses through the courts.

What is a Deed of Trust?

A Deed of Trust is a three-party agreement involving the borrower (trustor), the lender (beneficiary), and a neutral third party called the trustee. The borrower transfers temporary title of the property to the trustee, who holds it as security for the loan until it is repaid.

Key Features of a Deed of Trust

  • Three Parties Involved: Borrower, lender, and trustee.
  • Who holds title: The trustee holds title as security only, and in many states that is bare legal title and nothing more. The borrower keeps possession and every other ownership right.
  • Foreclosure Process: The power of sale clause a deed of trust normally carries allows non-judicial foreclosure where state law permits it, which is typically faster and less costly than going through the courts.

A mix-up worth avoiding

Lien theory and title theory describe what the security instrument does to legal title. Mortgage and deed of trust describe which instrument a state uses. These are two separate questions and they do not line up neatly, so the name on the document does not tell you which theory the state follows.

California is the clearest example. It is the largest deed of trust state in the country and it is a lien theory state. Massachusetts runs the other way: it follows title theory and uses mortgages. Check the state rather than inferring the rule from the instrument.

How Mortgages and Deeds of Trust Differ

Feature Mortgage Deed of Trust
Parties Involved Borrower, Lender Borrower, Lender, Trustee
Who holds legal title Depends on whether the state follows lien or title theory The trustee, as security only
Foreclosure Process Judicial, unless the mortgage carries a power of sale Usually non-judicial, where state law allows it
Lien or title theory Set by state law, not by the instrument Set by state law, not by the instrument

Both mortgages and deeds of trust must include an accurate legal description of the property being used as collateral. The legal description defines the property’s boundaries, ensuring there is no ambiguity about what is being secured.

An inaccurate or incomplete legal description can lead to serious issues, including challenges to the lender’s claim or difficulties in foreclosure proceedings.

  • Metes and Bounds: Describes the property using measurements and landmarks.
  • Rectangular Survey System: Uses a grid-based system of townships and sections.
  • Lot and Block: References recorded plat maps for properties in subdivisions.
