A personal guarantee is where your business's lease reaches past the company and into your own bank account.

One clause in a commercial lease can undo the liability protection you formed your business to get: the personal guarantee. By signing it, you personally promise to cover the lease if the business can’t — putting your own assets on the line for an obligation that can outlast the company. Landlords routinely require guarantees, especially from smaller or newer businesses, but they are negotiable. This guide explains how personal guarantees work, the real risks, and how to limit your exposure.

We help businesses get this right from the start. This is general information, not advice on a specific situation.

A personal guarantee reaches past the company and into your own bank account.

What a personal guarantee does

A personal guarantee is a promise by an individual — usually the business owner — to personally satisfy the lease obligations if the business fails to. The Legal Information Institute’s overview of a law.cornell.edu describes it as a promise to answer for another’s debt or default. In the lease context, it means that if the business can’t pay rent or breaches the lease, the landlord can pursue the guarantor’s personal assets — savings, home, other property. This effectively pierces the liability shield an entity provides, which is why a guarantee is one of the most consequential terms a business owner can sign.

The guarantee can outlast the business it was meant to support.

Why landlords require them and the risk

Landlords require personal guarantees to reduce their risk, especially with newer or smaller businesses that lack a long track record or substantial assets. From the tenant’s side, the risk is serious: a broad guarantee can make you personally liable for the entire remaining lease — potentially years of rent — if the business fails, and that liability can survive the business itself. Because a commercial lease is a large, multi-year obligation, an unlimited guarantee can expose an owner to devastating personal liability. As a law.cornell.edu term, it is enforceable as written, which is exactly why its scope must be negotiated.

Ways to limit a guarantee

A personal guarantee doesn’t have to be all-or-nothing. Several structures reduce exposure. A cap limits the guarantee to a fixed dollar amount. A time limit ends the guarantee after a set period or once conditions are met. A “good-guy guarantee” limits liability to amounts owed up to the point the tenant properly vacates and returns the space, rather than the full remaining term. A “burn-off” guarantee reduces or eliminates the obligation after the tenant maintains good standing for a defined period. Negotiating one of these structures can dramatically shrink personal risk while still giving the landlord meaningful assurance.

Negotiating before you sign

Because a guarantee is enforceable as written and the need to invoke it arises only when things go wrong, the time to address it is before signing — when you have leverage. Push to limit the amount, duration, or triggering conditions, or to eliminate the guarantee where your business’s strength allows. Understand exactly who is guaranteeing what, whether spouses are being asked to sign, and how the guarantee interacts with the lease term and any renewals. A guarantee you’ve negotiated to a bounded, understood risk is far safer than an open-ended one signed without scrutiny. This is a term worth real attention.
