You signed a contract with an LLC. The work got done. Now the invoice is 60 days late, the owner stopped answering, and when you finally got a lawyer to look at the company, it has no assets, no bank balance, and no other employees. The LLC is a shell. Your only real defense against this is something you put in the contract before the job started: a personal guarantee clause that puts the owner on the hook for the debt, not just the company.
What a Personal Guarantee Clause Actually Does
A personal guarantee is a sentence (or short paragraph) in your contract where an individual agrees to pay your invoice if the business does not. If the LLC defaults, the guarantor's personal assets are on the table: bank accounts, wages, sometimes property.
Without it, suing an LLC that has nothing in the bank is a paper victory. With it, you can pursue the owner directly. That difference is what makes a payment-focused contract actually collectible.
This is standard practice in commercial lending. Banks require personal guarantees from small-business owners as a matter of course. Contractors can ask for the same protection. Most owners say yes, because the alternative is you walking away from the job.
When to Ask for One
Not every job needs a personal guarantee. Use it when the risk is high enough to justify a harder negotiation up front:
- The client is a brand-new LLC with no operating history
- The contract value is more than one to two weeks of your labor
- The client is a single-member LLC or a holding company with no obvious assets
- You are a sub working for a general contractor you have never worked with before
- The owner asked for net-30 or net-60 terms instead of paying on completion
Established companies with a real footprint (five years of history, a real office, public reviews) usually do not need one. Reserve the ask for situations where the entity could evaporate by the time you send the invoice.
Exact Language That Holds Up
The clause has to be explicit. Vague language ("the owner stands behind this work") will not survive a challenge in court. A guarantee has to identify the guarantor by name, state it is personal and unconditional, and be signed separately from the business signature line.
Personal Guarantee. The undersigned individual, [Full Legal Name], personally, absolutely, and unconditionally guarantees the full and timely payment of all amounts owed by [Client Company, LLC] under this Agreement, including the principal invoice amount, any late fees, interest, court costs, and reasonable attorneys' fees incurred in collection. This guarantee is a guarantee of payment and not of collection, and is binding on the guarantor's heirs and assigns. The guarantor waives notice of default and consents to the jurisdiction of the courts of [State].
Guarantor signature: ______________________ Date: __________
Print name: ______________________
Two details matter. The signature line for the guarantee has to be separate from the line where the same person signs as a company officer. And the word "personally" has to be in the clause. Courts have thrown out guarantees where an owner signed only once with "CEO" next to their name, ruling they signed in a corporate capacity, not a personal one.
Getting It Signed Without Killing the Deal
Most contractors do not ask for a personal guarantee because they think it will scare the client off. It rarely does, if you frame it as standard. A few approaches that work:
- Put it in the contract by default, not as a separate document. The owner reviews one paperwork packet and signs once.
- When asked about it, say: "It is standard on jobs over $X with a new client. My bank requires the same thing from me on my line of credit."
- Offer to drop the guarantee in exchange for a larger deposit (40% to 50% up front instead of 20%). About half the time, the client picks the deposit. Either way you are protected.
- Keep the cap reasonable. A guarantee limited to the unpaid invoice amount is easier to accept than one with open-ended liability.
If a client flatly refuses both the guarantee and a larger deposit, that is information. It tells you the LLC is the only thing they want you to be able to pursue. Price the job accordingly or walk.
When a Guarantee Still Will Not Save You
A personal guarantee is not bulletproof. It can fail in a few specific situations:
- The guarantor has no personal assets either: judgment-proof debtors are judgment-proof guarantors
- The clause is buried in fine print without a separate signature, and the guarantor argues they did not see it
- You materially changed the scope or amount of work without getting the guarantor to reaffirm
- The contract was signed under duress, fraud, or by someone without authority
State laws also vary on what a guarantee can cover. Some states cap attorneys' fees, some require specific notice language, and a few require the guarantee to be on a separate page. If your contracts run statewide, have a local attorney review the clause once before you start using it.
What to Do When You Have to Enforce It
When the LLC defaults, your demand letter goes to both the company and the guarantor by name. Address one envelope to "[Owner Name], Personally" at their home address (you can usually find it on the LLC filing). The other goes to the business address. Both should be certified mail with return receipt.
If the demand goes ignored, the next step looks like any other unpaid-invoice escalation: a final notice, then a small claims filing or civil suit depending on the amount. The difference is you sue the owner and the company as co-defendants. A clean collections timeline with a personal guarantee in your file is one of the strongest positions a contractor can be in. If you need to draft the letter that activates the guarantee, PaperHammer generates the three-letter sequence addressed to both the LLC and the guarantor, with your state's small claims limit referenced in the final demand. The document drafting is the part that takes the longest; the system handles it in about five minutes.
