Personal Guarantees: When to Sign and When to Push Back

One of the foundational reasons entrepreneurs form LLCs and corporations is to separate personal assets from business liabilities. But a personal guarantee can erase that separation in a single signature.

Personal guarantees are common in business contracts — from commercial leases to equipment financing to vendor agreements. Knowing when they are a reasonable business reality, when they are negotiable, and when they cross a line is knowledge every founder needs before putting pen to paper.

What Is a Personal Guarantee?

A personal guarantee is a legal commitment by an individual — typically a founder, owner, or officer — to be personally responsible for a business obligation if the business fails to perform. When you sign a personal guarantee, you are telling the other party: if my company does not pay or perform, I will.

This means your personal bank accounts, home, investments, and other assets can be reached by the creditor if the business defaults. The liability protection your LLC or corporation provides does not apply to obligations you have personally guaranteed.

When Are Personal Guarantees Most Common?

Personal guarantees appear most frequently in situations where the counterparty perceives elevated risk — typically when the business is early-stage, lacks a long credit history, or is entering into a high-value obligation. Common contexts include:

• Commercial real estate leases, where landlords routinely require founder guarantees for new or small businesses
• Small Business Administration (SBA) loans, where personal guarantees are generally required for owners holding 20% or more of the business
• Equipment financing and capital leases
• Lines of credit or term loans from banks and alternative lenders
• Large vendor or supplier contracts with extended payment terms
• Franchise agreements

In each of these situations, the counterparty is extending credit, space, or resources based in part on confidence in you personally — not just in your business entity.

When a Personal Guarantee May Be Worth Signing

There are circumstances where a personal guarantee is a reasonable trade-off to access capital, space, or a critical business relationship. If you are an early-stage founder without significant business credit history, a lender or landlord may have no other basis for extending trust. In those situations, a well-negotiated personal guarantee — with defined limits — can be a practical path forward.

The key word is negotiated. Even when a personal guarantee is unavoidable, its scope is often not fixed. The terms — including how much you are guaranteeing, for how long, and under what conditions — are frequently open to negotiation.

When to Push Back — or Walk Away

Not every request for a personal guarantee is justified, and not every guarantee request should be accepted as presented. Push back — or seek contract review from a business attorney — in the following situations:

The guarantee is unlimited and open-ended

An unlimited personal guarantee exposes you to the full extent of the obligation with no ceiling. Negotiate for a capped guarantee — one limited to a specific dollar amount or a defined percentage of the obligation.

The guarantee survives well beyond the contract term

Some guarantee language extends your personal liability long after the underlying contract has expired or been fulfilled. Make sure the guarantee has a clear termination date tied to the contract itself.

Your business is established and creditworthy

If your company has a track record, revenue, and assets, a counterparty's insistence on a personal guarantee deserves scrutiny. At some stage, your business should be able to stand on its own credit. Push back and make the case.

You are about to sell the company

Outstanding personal guarantees are a common issue during M&A due diligence. If you have signed personal guarantees on commercial leases or other contracts, a buyer will want to know — and may require that those guarantees be released or assumed before closing. Cleaning up your guarantee obligations before going to market is part of good exit preparation.

The Bottom Line

Personal guarantees are a reality of business, but they should never be signed without understanding exactly what you are agreeing to. The terms matter as much as the decision itself. A guarantee that is capped, time-limited, and tied to specific obligations is meaningfully different from a broad, open-ended one — and the difference is usually negotiable.

Before you sign any contract that includes a personal guarantee, have it reviewed by a business attorney who can identify the risks, propose alternatives, and negotiate terms that protect you.
