Personal Guarantees on Equipment Loans and Leases: What Business Owners Sign
Key takeaways
A loan personal guarantee is a signed promise that the owner, not only the business, will repay the debt if the business can’t, and it is separate from the equipment that secures the loan.
- The lien covers the machine. The guarantee covers you.
- A repossessed machine that sells for less than the balance can leave a gap, and a guarantor can be asked to fill it.
- Limited, unlimited, or continuing: one word in the document changes what you owe.
- An LLC doesn’t protect you from a guarantee you signed yourself.
A loan personal guarantee gets a line of its own in the paperwork. Your name, beside the company’s. It’s easy to skim past when the machine has your attention.

What a Loan Personal Guarantee Covers
A personal guarantee, also called a guaranty, is a contract in which an individual, the guarantor, promises the lender to pay a business’s debt if the business doesn’t. A second source of repayment. The business is the borrower. The owner who signs becomes liable for the same debt, separately from the company.
That’s why forming an LLC or a corporation doesn’t settle it. The SBA’s guide to business structures says LLCs protect owners from personal liability in most instances, but a promise you sign in your own name is a debt of yours. A sole proprietor has no shield to lose. The same SBA page says a sole proprietor can be held personally liable for the business’s debts and obligations, guarantee or not.

Guarantee vs Equipment Lien, Side by Side
Under UCC §9-203(b), a security interest is enforceable only when value has been given, the debtor has rights in the collateral, and the debtor has authenticated a security agreement that describes it. The UCC-1 filing comes after, as public notice, and under §9-515 it stays effective five years from the filing date. The guarantee pledges nothing.
| Equipment lien | Personal guarantee | |
|---|---|---|
| What it is | A claim on the machine | The owner’s own promise to pay |
| Who signs | The business | The owner, by name |
| How long it runs | UCC-1: five years unless continued | As the document says |
| After a repossession sale | Proceeds go to the debt | A shortfall can be pursued |
Read the collateral description. A serial number ties the lien to one machine. Under §9-108(c), “all the debtor’s assets” doesn’t reasonably identify collateral in a security agreement, though under §9-504(2) a financing statement may say it covers all assets. Blanket liens get their own treatment in our piece on collateral on working capital loans.
When the Machine Doesn’t Cover the Debt
If the business stops paying, the lender can repossess the machine and sell it. UCC §9-610(b) requires every aspect of the sale, including the method, manner, time, place, and other terms, to be commercially reasonable. Proceeds go against the balance.
Short of the balance? Under §9-615(d), “the obligor is liable for any deficiency.” Section 9-102(a)(59) defines an obligor to include a person “otherwise accountable in whole or in part for payment or other performance of the obligation,” language that can reach a guarantor. Your guaranty’s wording and your state’s law decide whether it does.
Look for the word “waive.” A guaranty may ask the guarantor to give up notice of default or objections to how the collateral is sold. Whether a waiver holds is an attorney’s question.
A Personal Guarantee on a Lease
In a true lease the lessor owns the machine during the term. The guarantee backs the lease payments and whatever else the lease makes the business owe.
Then check the label. Under UCC §1-203(b), a lease the lessee can’t terminate creates a security interest if it also meets any one of four tests, and one of them is that the lessee may become the owner for no additional or nominal additional consideration. A $1 buyout lease is the familiar example. The label decides which part of the UCC governs a default, and your guarantee sits under it.
The terms to read alongside it are in our guide to the equipment lease agreement.
Clauses to Read Before Signing
A guaranty can run several pages. A reading list, nothing more. It’s general information, not a review of any document.
- Limited or unlimited? A limited guarantee names a ceiling, in dollars or as a share of the debt. An unlimited one doesn’t, and wording like “all obligations” is the tell.
- If two owners sign, can the lender collect the whole amount from either one? That’s joint and several liability. Ask which one you have.
- The word “continuing.” It can carry the guarantee past this loan or lease to others you sign with the same lender.
- Waivers, covered above, plus any clause that lets the lender change the deal without asking you.
- Does the guarantor also owe the lender’s collection costs and legal fees?
- What ends it, in writing. Don’t assume that selling the business releases you.
Try this rule on each clause: what does it add on top of the machine? Your savings? Your next lease? That’s the clause to put in front of an attorney.
Spouses, Co-Owners, and SBA Loans
Regulation B, which covers business credit as well as consumer credit, limits when a creditor can require a spouse’s signature. Under 12 CFR 1002.7(d), a creditor generally can’t require an applicant’s spouse to sign a credit instrument when the applicant meets its creditworthiness standards alone, and 12 CFR 1002.2(e) counts guarantors as applicants for that rule. If anyone is asked to sign, ask in what capacity. Ask why, too.
Co-owners are a separate matter. Under 13 CFR 120.160(a), holders of at least a 20 percent ownership interest generally must guarantee an SBA-backed loan, and SBA Form 148 is the unconditional guarantee lenders may use for it. Outside SBA programs the lender sets who signs, so the document, not a headline rule, tells you. Equipment financing that sits beside an SBA loan is its own topic, covered in equipment financing with an SBA loan.
Questions Owners Ask About Guarantees
If the machine is the collateral, why does a lender want my signature too?
Because a repossessed machine doesn’t always sell for what’s owed. The guarantee is the backup. Whether a given lender asks for one is that lender’s call.
Does an LLC keep a guarantee from reaching me?
No. The SBA’s guide says LLCs protect owners from personal liability in most instances, and signing a guarantee is the exception you make yourself. It’s your name on a separate contract.
Once the lender repossesses, is the guarantor done?
Not automatically. UCC §9-615(d) says the obligor is liable for any deficiency after the sale, and a guarantor can be an obligor. The guaranty’s wording and your state’s law do the rest.
Can a lender make my spouse sign too?
Regulation B restricts it. Under 12 CFR 1002.7(d)(1), a creditor generally can’t require an applicant’s spouse to sign a credit instrument when the applicant meets its creditworthiness standards alone. A spouse who’s asked to sign should find out in what capacity and take the document to an attorney first.
What actually ends a personal guarantee?
Two things, usually. The debt it backs is paid in full, or the lender releases the guarantor in writing. A continuing guaranty may reach beyond one loan, so read what yours covers. Selling the business doesn’t release you on its own.
Does a sole proprietor have to sign a guarantee at all?
A sole proprietor is already personally liable. The SBA notes that a sole proprietorship isn’t a separate entity and that the owner can be held personally liable for its debts. A lender may still ask for a guaranty, and its wording may go further than the law does. Read it.
