A "secured debt" is an obligation you owe that's backed by collateral a creditor can recover if you default. ("Default" means failing to follow the contract terms, such as making the required payments.)

Secured debts are created with liens. Liens can be voluntary or involuntary. Home mortgages and car loans are examples of secured debts that you incur voluntarily. Real property tax liens, by contrast, are involuntary liens.

What Is a Voluntary Lien?

Usually, you voluntarily agree to give a creditor a security interest in your property. For instance, as a condition for making a home loan, a lender typically requires you to sign a mortgage (or, in some states, a deed of trust). A mortgage or deed of trust is an agreement that grants a lender a security interest, or lien, against real property. The lien allows for a foreclosure auction if the homeowner falls behind on the monthly payment.

You can also grant a lender a lien against personal property, which is anything you own or have an interest in that isn't real estate (real property). Personal property includes vehicles, equipment, furniture, tools, inventory, shares of stock, other types of investment interests, and even cash.

Typically, you grant a lien against personal property through a security agreement. Before extending a new car loan, for example, a lender will require you to sign a security agreement granting a lien against the vehicle you are buying. It's the voluntarily lien that allows the lender to repossess your car if you don't pay as agreed.

What Is an Involuntary Lien?

Involuntary liens are security interests imposed against your property by a state or federal statute or court order. No agreement is involved. Involuntary liens include:

How a Creditor "Perfects" a Lien

One of the steps that a secured creditor must take to protect its right to collect is to perfect its lien. "Perfection" is a legal term that refers to the action required to give other creditors and interested parties notice of a lien or security interest. The action to perfect a lien depends on the property type and applicable state law. For example:

Real Property

In most states, the lender perfects its lien by recording (filing) mortgages and deeds of trusts in the county where the property is located.


Lenders usually can perfect liens against cars, motorcycles, and trucks by a filing with the state motor vehicle department and a notation on the certificate of title.

Tangible Personal Property

Security interests in most tangible personal property—like equipment, furniture, tools, goods, and materials—are perfected by filing financing statements. A financing statement is a document that identifies the borrower, lender, and collateral for a secured debt.

Unlike security agreements, financing statements don't have to be signed to be effective. A creditor can file a financing statement as long as you have signed the security agreement for the collateral that it is supposed to cover. In most states, financing statements are filed with the secretary of state.

Perfecting a lien is a critical step for any creditor. Sometimes, borrowers grant liens against the same property, like your home, to multiple creditors. Take, for example, a home equity line of credit, which is usually junior to the mortgage you took out to buy your house. A junior lien, like a home equity line of credit, can, in effect, move up in priority if the holder of the first mortgage fails to perfect its interest.

In bankruptcy, the consequences of a lender's failure to perfect a lien can be even more serious. If you file bankruptcy, the court has the power to set aside a lien that has not been properly perfected. A lien that is set aside is treated as if it never existed in the first place—meaning that the lender becomes an unsecured creditor.

How a Creditor Can Collect a Secured Debt

One of the big differences between an unsecured debt and a secured debt is how the creditor can enforce its rights if you fail to make payments. For most unsecured debts, creditors must first sue you in court before they can take any of your property. However, A secured creditor can move to enforce rights if you default on your loan obligations and have not filed bankruptcy. Remedies to enforce secured debts include:


Secured creditors may not trespass on private property or breach the peace, but they usually don't have to go to court before repossessing cars or other motor vehicles.


A lender may enforce a home loan by foreclosing its mortgage or deed of trust. In some states, foreclosure doesn't require any court action and may be completed within a matter of a few months. In other states, where court approval is needed, foreclosure typically takes much longer.

Court Action

A secured creditor has the additional option of filing a court action to obtain a judgment against you. Depending on applicable state law, a creditor may seek a judgment for the entire obligation that you owe or the balance left after deducting the value of any collateral that it recovers.
