What Is a Guaranty Clause?

Definition: Makes a third party personally responsible for the obligations or debts of one of the contracting parties.

Also called a personal guarantee, a guaranty of payment, or a continuing guaranty.

What this clause actually does

A guaranty adds a second party — a person, or another company — who must perform or pay if the primary party does not. When that second party is an individual, the guaranty typically reaches personal assets. That is the whole point of asking for it, and it is why this clause deserves more attention than almost anything else in a small commercial agreement.

It is worth being blunt about the structural effect: a person who set up a company to separate business risk from personal risk, and then signs a personal guaranty, has undone that separation for this obligation. The company still exists; the protection, for this debt, does not.

Four variables that set the exposure

• Payment or collection. A guaranty of payment generally lets the creditor come straight to the guarantor on default. A guaranty of collection generally requires them to pursue the primary obligor first. These are very different obligations wearing similar names.
• Limited or unlimited. Is there a capped amount and a defined list of obligations — or is it “all present and future obligations of every kind”?
• Joint and several, or proportionate. With joint and several liability among several guarantors, each can be pursued for the whole amount, not a share. Whether the others can pay is your problem, not the creditor's.
• Continuing or transaction-specific. A continuing guaranty covers future advances, renewals, increases and amendments — including ones agreed between the other two parties after you signed, and without your involvement.

Where it bites

• The business fails and the obligation does not. A personal guaranty on a lease, an equipment line or supplier credit survives the company that the debt belonged to.
• The exposure grows without you. “Continuing and unconditional” wording means the creditor and the primary obligor can increase the facility, extend it, or amend it, and you remain bound to the new version.
• Buried waivers. Guaranties commonly waive notice of default, the right to require the creditor to pursue the primary obligor or the collateral first, and defences the primary obligor itself would have had. Each of those is a separate concession, and they are usually in one dense paragraph.
• It widens the asset pool. A co-owner's or spouse's signature is sometimes requested precisely because it changes which assets can be reached.
• It survives the sale of the business. People sell a company and remain on the hook for years, because nobody obtained a written release at closing. The buyer assuming the obligation is not the same as the creditor releasing you.
• Costs ride along. Interest at the default rate, legal fees and collection costs are frequently guaranteed too.

What to negotiate

• A hard cap on the amount, and a defined, closed list of the obligations guaranteed.
• An end date, or a release trigger — sale of the business, a covenant test met, a stated period of clean payment history, a reduction of the balance below a threshold.
• Require them to demand from the primary party first, and to pursue the collateral first.
• Keep your defences rather than waiving them, and keep the right to notice of default.
• No growth without consent. Any amendment that increases the guaranteed amount, extends the term, or adds obligations requires your written agreement.
• Proportionate, not joint and several, where there are several guarantors — or at least a per-guarantor cap.
• A written release mechanism, and obtain the actual release document at closing if you sell.
• Ask what else would do. A larger deposit, a prepayment, a letter of credit, a shorter term, more collateral from the company, or a higher rate can sometimes replace a personal guaranty entirely. That question is often simply never asked.

What a reasonable version looks like

Capped in amount; limited to identified obligations; time-limited or releasable on defined milestones; notice of default required; the guarantor's own defences preserved; amendments that increase exposure requiring written consent; proportionate liability where there are several guarantors; and a stated, workable release mechanism.

What to push back on hardest

• An unlimited, continuing, unconditional guaranty of “all present and future obligations.”
• A blanket waiver of notice and of all defences.
• Joint and several liability, uncapped, alongside guarantors whose finances you cannot see or control.
• No release path on exit from the business.
• Confession-of-judgment or power-of-attorney wording attached to the guaranty.
• Obligations that can be increased by agreement between the other two parties.

Questions worth asking before you sign

• What exactly am I guaranteeing, and up to what maximum amount?
• Is there an end date, or any way out short of the debt being repaid?
• Must you pursue the company and the collateral before coming to me?
• Can the guaranteed amount grow without my signature?
• How do I get released, and what document will I receive?
• What happens if I sell the business?
• Are default interest, legal fees and collection costs included?
• Who else has signed, and am I liable for their share as well as mine?
• What alternative security would you accept instead of a personal guaranty?

Not legal advice. What's My Contract is not a law firm, and this page is general information about how a clause of this type is usually written — not advice about your contract, and not a statement of the law in any particular place. How a clause is read, and whether it can be relied on, depends on where you are, what the rest of the agreement says, and facts a general explainer cannot know. Before you sign, refuse, or act on any clause, have a lawyer licensed in your jurisdiction read your actual document.
