Security Agreement Template: How to Write One

A security agreement is the document that turns a loan into a secured loan. Without one, a lender who isn't repaid is just another unsecured creditor standing in line. With one, that lender holds a legal claim on specific property and can take it back if the borrower defaults.

This guide walks through what a security agreement does, the clauses it has to contain, the difference between attachment and perfection, and the steps to write one that actually holds up.

What Is a Security Agreement?

A security agreement is a contract in which a borrower (the debtor) grants a lender (the secured party) a security interest in property (the collateral) to back a debt or obligation. If the debtor doesn't pay, the secured party can seize the collateral and sell it to recover what it's owed.

These agreements are governed by Article 9 of the Uniform Commercial Code (UCC), a body of law adopted in some form by every state. Because the UCC standardizes how security interests work, the same basic rules apply whether you're financing a $5,000 piece of equipment or a multimillion-dollar inventory line. The broader framework of how the UCC governs commercial transactions is worth understanding before you draft, since Article 9 borrows definitions from the rest of the code.

A security agreement rarely travels alone. It usually sits alongside a loan agreement or a promissory note that spells out the repayment terms, while the security agreement handles the collateral side of the deal.

Security Agreement vs. Promissory Note vs. UCC-1

These three documents get mixed up constantly, so it helps to separate them:

• Promissory note: the borrower's written promise to repay a specific sum on specific terms. It creates the debt.
• Security agreement: grants the lender an interest in collateral to secure that debt. It creates the security interest.
• UCC-1 financing statement: a short public filing that gives notice of the security interest to the world. It perfects the interest.

You can have a promissory note with no collateral (an unsecured loan). You can have a security agreement that references several obligations at once. And the UCC-1 doesn't create any rights on its own; it only protects rights the security agreement already created. Getting all three right is what separates a lender who recovers from one who writes off the loss.

Key Parts of a Security Agreement

A workable security agreement needs the following clauses. Skipping any of them tends to create the exact gap a defaulting borrower's lawyer will exploit.

1. Identification of the Parties

Name the debtor and the secured party using exact legal names. For a registered business, use the name on its formation documents, not a trade name or DBA. Article 9 is unforgiving here: a UCC-1 filed under the wrong version of the debtor's name can be treated as ineffective, which leaves the lender unperfected even though everyone knew who the borrower was.

2. The Granting Clause

This is the heart of the document. The granting clause is the operative sentence where the debtor actually conveys the security interest, something like: "Debtor hereby grants to Secured Party a security interest in the Collateral described below to secure the Obligations." Without a clear grant, you have a description of collateral but no security interest in it.

3. Description of the Collateral

The collateral has to be described well enough to reasonably identify it. You don't need a serial number for every item, but the description can't be so vague that nobody can tell what's covered. A description by category ("all equipment now owned or hereafter acquired") is generally fine in the security agreement itself. Common approaches:

• Specific collateral: a named asset, e.g., "one 2024 Bobcat T76 compact track loader, serial #..."
• Categories: "all inventory," "all accounts receivable," "all equipment"
• Blanket lien: "all assets of the Debtor, whether now owned or hereafter acquired"

Note that "all the debtor's assets" is acceptable in the security agreement but is not a sufficient collateral description on the UCC-1 in many cases, where you may need to say "all assets" carefully or list categories. The two documents have slightly different standards.

4. The Secured Obligations

Spell out what the collateral is securing. Is it a single loan? A revolving line of credit? All present and future obligations the debtor owes the secured party? A broad "future advances" or "dragnet" clause lets the same collateral secure later loans without signing a new agreement, which is convenient for lenders but something borrowers should read closely.

5. Debtor Covenants and Representations

These are the borrower's ongoing promises that protect the collateral's value. Typical covenants require the debtor to:

• Keep the collateral insured and in good repair
• Not sell or transfer the collateral without consent (outside ordinary-course inventory sales)
• Pay taxes and keep the collateral free of competing liens
• Notify the secured party before changing its name, structure, or location

6. Events of Default

List exactly what counts as default. The obvious trigger is missing a payment, but most agreements add others: breaching a covenant, going bankrupt, letting insurance lapse, or another creditor seizing the collateral. The more precisely default is defined, the faster the lender can act when something goes wrong.

7. Remedies on Default

State what the secured party can do once default occurs: accelerate the debt (demand the full balance at once), repossess the collateral, and sell or lease it. Article 9 requires that any disposition be commercially reasonable, so it's common to reference that standard directly. This clause is also where a personal guarantee often gets cross-referenced, since collateral alone may not cover the full debt.

Attachment vs. Perfection

This is the concept that trips up most first-time drafters, and it's the one that decides who gets paid in a bankruptcy.

Attachment makes the security interest enforceable against the debtor. Three things have to happen: the secured party gives value (the loan), the debtor has rights in the collateral (it owns it), and there's a signed security agreement describing the collateral. Once all three line up, the interest "attaches."

Perfection makes the interest enforceable against third parties, such as other lenders or a bankruptcy trustee. For most collateral, you perfect by filing a UCC-1 financing statement with the secretary of state where the debtor is located. For some collateral you perfect by taking possession (a pawned item) or control (a deposit account).

Why it matters: priority among competing creditors generally runs in order of perfection. A lender who attaches but never files a UCC-1 can be wiped out by a later lender who filed first. So the practical sequence is: sign the security agreement, fund the loan, then file the UCC-1 promptly, ideally the same day.

Types of Collateral

Article 9 sorts collateral into categories, and the category affects how you describe and perfect it. The common ones:

• Equipment: machinery, tools, and other goods used in a business
• Inventory: goods held for sale or lease
• Accounts: money owed to the business (receivables)
• Instruments and chattel paper: promissory notes and financing contracts
• Investment property: stocks, bonds, and securities accounts
• General intangibles: intellectual property, goodwill, and other non-physical assets

Most agreements also automatically reach proceeds, meaning whatever the collateral is converted into. If a borrower sells inventory, the security interest follows into the cash or receivable that results, as long as the agreement and filing are drafted to cover proceeds.

How to Write a Security Agreement: Step by Step

Step 1: Confirm the underlying debt. Make sure the loan, note, or obligation the security agreement secures is documented and clear. The security agreement points back to it.

Step 2: Identify the parties precisely. Pull the debtor's exact legal name from state records. Decide who the secured party is and confirm it has authority to lend.

Step 3: Describe the collateral. Choose between specific items, categories, or a blanket lien. Match the description to the deal: a single-equipment purchase calls for a specific description, while a working-capital line usually takes a broad one.

Step 4: Draft the granting clause. State plainly that the debtor grants a security interest in the described collateral to secure the obligations.

Step 5: Define the secured obligations. Decide whether the collateral backs one loan or all current and future debts, and write the dragnet language accordingly.

Step 6: Add covenants, default events, and remedies. Protect the collateral's value during the loan, define what default looks like, and lay out what the lender can do about it.

Step 7: Sign and perfect. Have the debtor sign (an authenticated electronic signature works). Then file a UCC-1 financing statement with the correct secretary of state to perfect the interest.

Common Mistakes to Avoid

Using the wrong debtor name. A misspelled or informal name on the UCC-1 can void perfection. Use the registered legal name, character for character.

Vague collateral descriptions. "Various business property" doesn't reasonably identify anything. Be specific enough that a stranger reading the document could tell what's covered.

Forgetting to perfect. A signed security agreement that never gets a UCC-1 filing leaves the lender exposed to anyone who files first. Attachment without perfection is a half-finished job.

Filing in the wrong state. You file where the debtor is located (for a registered business, its state of formation), not where the collateral or the lender sits.

Ignoring future advances. If the lender expects to extend more credit later, the agreement should say so. Otherwise each new advance may need fresh documentation.

Skipping the relationship to other documents. The security agreement should reference the loan agreement or note it secures, so there's no question about which debt the collateral backs.

When You Need a Security Agreement

Use a security agreement whenever a loan or obligation is backed by specific property rather than just a promise to pay:

• Equipment financing: the financed equipment serves as collateral
• Business loans and lines of credit: banks routinely take a security interest in business assets
• Seller financing: a seller who lets a buyer pay over time can secure the unpaid balance
• Inventory and receivables financing: lenders advance against current assets
• Investor or shareholder loans: even informal loans into a business can be secured

If a deal involves real estate rather than personal property, you'd use a mortgage or deed of trust instead; Article 9 covers personal property and fixtures, not land itself.
