Mortgages in the United States:

Types of Mortgage Instruments

Two types of mortgage instruments are used in the United States: the mortgage (sometimes called a mortgage deed) and the deed of trust.
The mortgage

In all but a few states, a mortgage creates a lien on the title to the mortgaged property. Foreclosure of that lien almost always requires a judicial proceeding declaring the debt to be due and in default and ordering a sale of the property to pay the debt.
The deed of trust

The deed of trust is a deed by the borrower to a trustee for the purposes of securing a debt. In most states, it also merely creates a lien on the title and not a title transfer, regardless of its terms. It differs from a mortgage in that, in many states, it can be foreclosed by a non-judicial sale held by the trustee. It is also possible to foreclose them through a judicial proceeding.

Most "mortgages" in California are actually deeds of trust. The effective difference is that the foreclosure process can be much faster for a deed of trust than for a mortgage, on the order of 3 months rather than a year. Because the foreclosure does not require actions by the court the transaction costs can be quite a bit less.

Deeds of trust to secure repayments of debts should not be confused with trust instruments that are sometimes called deeds of trust but that are used to create trusts for other purposes, such as estate planning. Though there are superficial similarities in the form, many states hold deeds of trust to secure repayment of debts do not create true trust arrangements.
