Personal Guarantee Template: How to Write a Guaranty

A personal guarantee is the document that turns a business debt into a personal one. When a company is young, thinly capitalized, or has no credit history of its own, lenders and landlords rarely take it at its word. They want a real person on the hook, someone whose house, savings, and paycheck are reachable if the business stops paying. The personal guarantee is how they get that.

If you own a business, you have probably signed one without reading it closely. If you are drafting one as a lender or vendor, the wording decides whether you can actually collect. This guide covers what a personal guarantee is, the different forms it takes, the clauses that matter, and how to write one that holds up.

What is a personal guarantee?

A personal guarantee is a written promise by an individual to repay a debt or perform an obligation if the primary party, usually a business, fails to do so. The person making the promise is the guarantor. The party they are promising to pay is the creditor or beneficiary.

The key feature is that the guarantee reaches past the business and into the guarantor's personal assets. A limited liability company or corporation normally shields its owners from company debts. A personal guarantee deliberately removes that shield for a specific obligation. That is why lenders ask for one and why owners should think hard before signing.

You will see guarantees attached to:

• Small business loans and lines of credit
• Commercial leases, where a landlord wants the owner behind the company
• Equipment financing and vehicle loans
• Vendor and supplier credit accounts
• SBA loans, which require a guarantee from anyone owning 20% or more

A personal guarantee is a contract in its own right, separate from the underlying loan or lease. It can be a standalone document or a clause buried inside a larger agreement. Either way, it is enforceable against the individual who signs it.

Types of personal guarantees

Not all guarantees carry the same risk. The differences below decide how much a guarantor can lose, so they belong at the top of any negotiation.

Unlimited guarantee

An unlimited guarantee puts the guarantor on the hook for the full debt: principal, interest, late charges, and the creditor's legal and collection costs. There is no cap. If the business borrows more under the same facility, the guarantee usually stretches to cover that too. This is the version lenders prefer and the one guarantors should resist.

Limited guarantee

A limited guarantee sets a ceiling. The cap might be a fixed dollar amount, a percentage of the outstanding balance, or a limit tied to a window of time. When several owners guarantee the same loan, a limited guarantee can also split liability so each person covers only their ownership share.

Several vs. joint and several

This distinction matters whenever more than one guarantor signs:

• Several liability means each guarantor is responsible only for their stated portion. If you guarantee 30%, the creditor can pursue you for 30% and no more.
• Joint and several liability means the creditor can collect the entire debt from any one guarantor. If your co-owner disappears, you can be left paying 100% and then chasing the others yourself.

Creditors push for joint and several because it gives them the most flexibility. Guarantors should ask for several liability or at least a clear cap.

Continuing guarantee

A continuing guarantee covers a revolving or ongoing relationship, such as a line of credit or a supplier account that goes up and down over time, rather than a single fixed loan. It stays in force until the guarantor formally revokes it in writing. Pay attention to the revocation terms, because a continuing guarantee can quietly outlast the deal you thought you were signing for.

Key clauses in a personal guarantee

A guarantee that is missing the right clauses either fails to protect the creditor or exposes the guarantor to more than they bargained for. These are the provisions that do the work.

Identification of the parties and the obligation. Name the guarantor, the creditor, and the exact debt being guaranteed, whether that is a loan number, a lease, or a credit account. A guarantee that points to "all present and future obligations" is far broader than one tied to a single note.

Scope and amount. State whether the guarantee is limited or unlimited and, if limited, the precise cap. Spell out whether it covers only principal or also interest, fees, and collection costs.

Type of guarantee. Say plainly whether it is a guarantee of payment or a guarantee of collection. A guarantee of payment lets the creditor come straight to the guarantor the moment the business defaults. A guarantee of collection requires the creditor to exhaust remedies against the business first. Creditors want payment guarantees; they are far easier to enforce.

Waiver of defenses. Most creditor-drafted guarantees ask the guarantor to waive certain defenses, such as the right to demand that the creditor sue the business first, or to be notified before enforcement. Guarantors should read these waivers closely, because they strip away protections the law would otherwise provide.

Term and revocation. For a continuing guarantee, define how and when the guarantor can revoke it and whether revocation applies to future advances only or to the existing balance as well.

Release conditions. If you negotiated an exit, such as release after a revenue milestone or a stretch of on-time payments, write the trigger into the document. A handshake promise to release a guarantee later is worth nothing.

Governing law and jurisdiction. State which state's law applies and where disputes will be heard. Guarantor protections vary widely by state, so this clause has real consequences.

Signature and witnessing. The guarantor must sign in their personal capacity, not as an officer of the business. A signature that reads "John Smith, CEO" can undermine the entire point of the guarantee.

How to write a personal guarantee step by step

You can draft a guarantee from a blank page, but it is easier to follow a fixed order so nothing important is left out.

1. Identify the parties. Use full legal names and addresses for the guarantor and the creditor. If the guarantor is married and a spouse will also sign, name both.
2. Describe the underlying obligation. Reference the specific loan, lease, or credit agreement by date and number. Attach a copy if you can.
3. Choose the type and scope. Decide between a guarantee of payment or collection, and between unlimited and limited. If limited, state the cap in numbers and words.
4. Set the liability structure. If there are multiple guarantors, specify several or joint and several liability and each person's share.
5. Add the operative clauses. Include the waiver provisions, term, revocation rules, release conditions, and governing law.
6. Define default and demand. Explain what counts as a default and how the creditor must make a demand on the guarantor: in writing, to a stated address, within a set number of days.
7. Execute properly. Have the guarantor sign in their individual capacity, date it, and add a witness or notary. Give each party a signed copy.

A clear, well-ordered guarantee protects both sides. The creditor gets a document they can enforce; the guarantor gets terms they actually understood before signing.

Common mistakes that cost guarantors

The errors below show up again and again, and most of them favor the creditor.

• Signing an unlimited guarantee when a limited one was available. Owners often assume the cap is non-negotiable. It frequently is not, but only if you ask before signing.
• Missing the joint and several trap. Co-owners assume they are each liable for their share. Under joint and several liability, any one of them can be made to pay the whole thing.
• Ignoring the waiver of defenses. Those clauses can waive your right to make the creditor pursue the business first. That is a meaningful protection to give up without noticing.
• No release mechanism. The business grows, the loan seasons, and the owner stays personally liable for years because nobody wrote in an exit.
• Signing in the wrong capacity. Signing as an officer instead of an individual can create an argument that you never personally guaranteed anything. That helps the guarantor, but it is a fatal flaw if you are the creditor relying on the document.
• Letting a spouse sign without thinking it through. In community property states especially, a spouse's signature opens up marital assets. That decision deserves its own conversation.

If the obligation behind the guarantee is a loan, it pays to get the underlying paperwork right too. Our loan agreement template guide walks through the loan itself, and for shorter-term debts a promissory note often sits alongside the guarantee.

Is a personal guarantee enforceable?

Generally, yes, and that is the point. To hold up, a personal guarantee needs the basics of any contract: a clear written promise, an identifiable obligation, the guarantor's signature, and consideration. Consideration is usually the loan or credit the creditor extends in reliance on the guarantee, which is why guarantees are often signed at the same time as the underlying deal.

A few things can weaken or void a guarantee:

• It was never put in writing. Guarantees fall under the Statute of Frauds, so an oral promise to answer for someone else's debt is unenforceable in most states.
• The guarantor signed under fraud, duress, or a genuine mistake about what they were signing.
• The terms are so one-sided that a court treats them as unconscionable, which is rare but possible.
• The creditor materially changed the underlying deal without the guarantor's consent, which can discharge the guarantee.

Enforcement plays out much like collecting on any debt. The creditor makes a demand, and if the guarantor does not pay, they can sue and pursue a judgment against personal assets. The mechanics overlap heavily with debt instruments, and the same enforcement realities apply. Our guide on enforcing promissory notes covers the collection process in more depth.

When you need a personal guarantee

You will run into personal guarantees most often in these situations:

• Borrowing for a young business. Banks rarely lend to a company with no track record without an owner standing behind it.
• Signing a commercial lease. Landlords want a person on the hook for the rent if the business folds before the term ends.
• Opening vendor credit. Suppliers extending net-30 or net-60 terms to a new account often ask an owner to guarantee payment.
• Bringing on co-owners. When several people share a business, a guarantee paired with a clear ownership agreement sorts out who is responsible for what. Our shareholder agreement guide covers the ownership side of that relationship.

In each case, the guarantee is the creditor's insurance policy. Your job, whichever side you are on, is to make sure the document says exactly what both parties think it says.
