What Is a Personal Guarantee? The Sentence That Puts Your House on the Line

You formed an LLC so the business and your house would be different things. A personal guarantee is the sentence that quietly rejoins them.

A personal guarantee is a contract clause where a business owner promises that if the business doesn't pay, the owner will pay personally. It's the most common reason small-business owners think they have liability protection and find out, two years later, that they don't.

The clause shows up in vendor contracts, commercial leases, equipment financing, business credit cards, SBA loans, and even some software agreements. It's almost never highlighted at signing. It's almost always enforceable.

TL;DR

• A personal guarantee makes you personally responsible for a business debt, regardless of whether you have an LLC or corporation.
• The clause comes in many flavors: unlimited, capped, conditional, joint and several. Each behaves very differently when something goes wrong.
• Severity tiers: High risk is unlimited and personal. Medium risk is capped or limited in time. Low risk is conditional on specific bad-actor behavior.
• Most personal guarantees are negotiable. The other side expects you to ask. Most small-business owners don't.

What a personal guarantee actually says

A typical clause in a commercial lease:

The undersigned, individually and personally, hereby unconditionally
and irrevocably guarantees the full and timely payment and performance
of all obligations of Tenant under this Lease, including without
limitation all rent, additional rent, late fees, attorneys' fees, and
damages. This guaranty is a continuing guaranty and shall remain in
full force and effect until all such obligations have been satisfied
in full.

In plain English: if your business stops paying rent, the landlord can come after your savings, your house, your car, and your wages, the same way a bank could if you'd taken out the lease in your own name. The LLC didn't change that. You agreed to it on the line above your signature.

"Continuing guaranty" means the obligation doesn't expire when the lease term ends. If the business renews or holds over, you're still on the hook. "Unconditional and irrevocable" means you can't take it back later because the business is doing badly.

The four flavors, ranked by how much they hurt

High risk Unlimited personal guarantee. The clause above. You're personally liable for everything the business owes, with no cap and no end date. This is the default in most commercial leases and most SBA loan documents.

Medium risk Limited (capped) guarantee. The clause names a specific dollar limit. "Guarantor's liability under this Guaranty shall not exceed $50,000." If the business defaults on a $400,000 obligation, you owe $50,000, not the full amount. This is what you should be negotiating toward.

Medium risk Limited-in-time guarantee. The guarantee burns off after a defined period or condition. "This Guaranty shall expire and be of no further force or effect upon Tenant's payment of twelve consecutive months of rent without default." Once you've paid for a year, the clause goes away. New deals especially favor this structure.

Low risk Bad-boy or carve-out guarantee. The guarantee only kicks in if the business does something specifically bad: fraud, environmental violations, voluntary bankruptcy, unauthorized transfer of collateral. Common in commercial real estate. As long as you run the business cleanly, the personal guarantee never activates.

The five flavors side by side:

Flavor	Severity	Cap	Burn-off	Triggered by	Typical context
Unlimited continuing	High risk	None	None	Any business default	Commercial leases, SBA 7(a) loans
Capped	Medium risk	Named dollar amount	None	Any business default	Negotiated leases, vendor credit lines
Limited in time (sunset)	Medium risk	Often unlimited until expiry	Yes, on payment milestone	Default before the burn-off date	Negotiated commercial leases
Good-guy	Low risk	Liability ends on vacate	Auto on key handover	Holdover after written notice	NYC and major-metro commercial leases
Bad-boy / carve-out	Low risk	Often unlimited, rarely triggers	None	Fraud, environmental violations, voluntary bankruptcy, unauthorized transfer	Commercial real estate above ~$1M

Joint and several is the trap that surprises co-founders

High risk

In a multi-founder business loan:

Each Guarantor shall be jointly and severally liable for all
obligations under this Guaranty. Lender may proceed against any
Guarantor for the full amount of the indebtedness without first
seeking recovery from any other Guarantor or from Borrower.

What it means: You and your two co-founders signed. The bank doesn't have to chase all three of you. They can chase whichever one has the most assets and collect the entire balance. The two of you who paid less can sue each other for contribution after the fact, but the bank is already paid.

This is the structure that ends co-founder relationships. Push back: ask for "several" liability instead, where each founder is only responsible for a defined share (often pro rata to ownership). Or ask for a "marshalling" provision requiring the lender to pursue the business first, then split the rest pro rata across guarantors.

Where personal guarantees usually hide

You'll see them most often in five places:

1. Commercial leases. The landlord wants someone other than the LLC to chase if the business fails. This is the most-negotiated personal guarantee in small business.
2. SBA loans. Federal regulations require a personal guarantee from any owner of 20% or more. This one isn't really negotiable. But the cap and the carve-outs sometimes are.
3. Vendor credit applications. A two-page credit application for a $5,000 line at a supplier often hides a personal guarantee in the fine print of the signature block. People sign these without reading. The supplier files them and waits.
4. Equipment financing and business credit cards. Almost always require a personal guarantee. Sometimes capped at the line amount, sometimes unlimited.
5. Software and SaaS contracts. Less common, but enterprise SaaS deals signed by a small-LLC customer occasionally include a guarantee buried in the order form. Always read the signature page.

The shape of the clause is the same across all five. The word to search for in any contract is "personally" or "individually." If you find either word in the signature block or guaranty section, you have a personal guarantee.

How to negotiate it down without killing the deal

Most counterparties expect a guarantee negotiation. Five moves that often work, in roughly increasing order of difficulty:

1. Ask for a cap. "Guarantor's liability shall not exceed [3 months of payments / $50,000 / first-year rent]." Caps are the easiest concession because they preserve the lender's protection while limiting the personal blast radius.
2. Ask for a burn-off. "This Guaranty shall expire after Tenant has paid twenty-four consecutive months of rent without default." Burn-offs cost the other side less than caps. They often agree.
3. Ask for several, not joint and several. Especially with co-founders. Pro rata to ownership is the common compromise.
4. Ask for a carve-out structure. Move from full guarantee to a bad-boy guarantee that only triggers on fraud or willful misconduct. Common in commercial real estate above a certain deal size.
5. Ask for a security deposit instead. "Tenant will post a $25,000 security deposit in lieu of a personal guarantee." Money in escrow is sometimes preferable to chasing the owner personally.

If the other side won't move at all, that itself is information about the deal. A personal guarantee is the most aggressive version of the shifted risk shape from the contract red flags playbook. The lender's exposure becomes your exposure, and the language doing the shifting is usually four lines long. Worth knowing the other four shapes, since they tend to show up in the same set of documents.

What happens when one gets called

The procedure is usually:

1. The business defaults (a missed payment, a bankruptcy filing, a lease termination).
2. The counterparty sends a demand letter to the guarantor citing the clause.
3. If the guarantor doesn't pay, the counterparty sues the guarantor in their personal name, attaches a copy of the signed guarantee, and asks for a judgment.
4. The judgment can attach to bank accounts, real estate, wages, and tax refunds, depending on state law and homestead exemptions.

Some states (Texas and Florida, notably) have strong homestead exemptions that protect a primary residence from most judgments. Most states do not. The personal guarantee is the document that turns a business problem into a household problem. Read it before you sign. Negotiate it before you read again. Sign last.

For the broader pattern of payment terms that interact badly with personal guarantees, the payment terms in contracts guide walks through the late-fee and acceleration language that often makes a default worse than it looks.
