Security Instruments: Everything You Need To Know

Two people shaking hands after signing documents

When someone buys property, like a car or a house, they usually sign a loan agreement or promissory note. This agreement states that they will pay a certain amount of money within a specific time frame.

To ensure they get paid, the lender might ask for a security instrument, which can be a mortgage, deed of trust, or installment land contract. These instruments are legally binding, so both the lender and borrower need to understand what they are, how they work, and the legal implications.

What Is a Security Instrument?

A security instrument is a legally binding agreement between the lender and borrower or buyer and seller of a property. It provides a vehicle for the lender to enforce terms if the borrower fails to adhere to the loan agreement or promissory note terms. The security instrument also provides a way for the lender to recover some or all of the property value should the borrower default or the promissory note become invalid.

Unlike a loan agreement or promissory note, a security instrument is not concerned with the repayment terms. Instead, it focuses on enforcing the promissory note by transferring property ownership to the lender in the event of default.

Example

If you take out a home loan, you will likely sign a promissory note to pay monthly installments on your mortgage for 15-30 years. The bank handling your loan may also have you sign a security instrument in the form of a mortgage agreement, which allows the bank to take ownership of the property should you fail to repay your loan per the agreement terms.

Once the borrower satisfies the loan term, they receive a promissory note release and take full ownership of the property without further obligation to the lender.

Types of Security Instruments

Different types of security instruments apply depending on the circumstances of your purchase agreement.

MortgageDeed of TrustInstallment Land Contract

Legal enforcement may vary by state.
Redemption RightsSome states allow for redemption periods after foreclosure.Redemption rights may vary by state, typically limited.Enforcement of forfeiture clauses and recovery of property value may vary by state, potentially requiring more expensive legal action.
Default RiskDefaulting on mortgage payments may lead to foreclosure.Defaulting on payments may result in non-judicial foreclosure by the trustee.Defaulting on payments may lead to forfeiture of the contract and loss of property.

How Security Instruments Are Used in Real Estate

Although a promissory note establishes the payment terms for a real estate transaction, it does not necessarily establish consequences for non-payment. That is where the security instrument comes in.

The Role of Security Instruments

When you purchase a home or other real property, the lender may secure the promissory note through a security instrument. The instrument provides the lender collateral to recover the value of the loan if you default. In the case of a real estate transaction, the collateral is usually the property itself.

Common Security Instruments

In real estate, there are two common types of security instruments: mortgages and deeds of trust.

  • Mortgages: Lender holds the mortgage while the loan is outstanding, allowing them to take possession and sell the property if necessary.
  • Deeds of Trust: Similar to mortgages, but title is transferred to a neutral third party (trustee) who holds it for the lender’s benefit.

Importance of Security Instruments

  • Enables lenders to recoup their investment by selling the property if the borrower defaults.
  • Protects lenders from significant losses in case the borrower lacks assets to cover the loan.

Loan Documents

  • Standard home purchases involve both a mortgage and a promissory note.
  • Together, these documents cover loan amount, interest rate, payment terms, and the borrower’s repayment obligation.

Key Elements of Security Instruments

Understanding the different aspects of security instruments can help buyers, sellers, and lenders establish agreements that benefit everyone:

Involved Parties

Clarify who is involved in the transaction. This may include the buyer, seller, borrower, lender, or trustee. If any party represents an organization, such as a bank, include the name of the representative, their title, and the organization’s details.

Property Description

Describe the property in detail. This may include an address, lot number, or other location description for real estate transactions. If your security instrument is for a motor vehicle or other property, include the VIN, serial number, or additional identifying information.

This section should describe any damage or other existing conditions at the time of sale.

Loan Terms

While the promissory note or purchase agreement provides loan and repayment details, you should also include the following loan information in your security instrument:

  • Loan amount
  • Interest percentage and capitalization
  • Repayment amount
  • Installment schedule
  • Specific conditions relating to the loan and repayment

Default and Foreclosure

Explain the consequences of default. This section should clarify the specific time frames for default and what remedies are available to the lender or seller should the buyer violate the payment terms.

Describe forfeiture, foreclosure, penalties, and potential legal action here. Be detailed about the forfeiture, selling, or foreclosure process and the options available to both parties. Include any information about arbitration or other forms of alternative dispute resolution.

Legal remedies for default and foreclosure may differ by state, so check your state laws before signing a security instrument for a real estate or other property transfer.

Signature

The borrower and lender may sign the security instrument, depending on the details of your transaction. Review state laws to understand the signature requirements for legal documents like promissory notes and loan agreements.

What’s the difference between a security instrument and a security interest?

A security interest is the lender’s right to the buyer’s assets. It is established by a document that confirms the lender’s security interest.
