Signing a personal guarantee: read this first

Corporate & Commercial31 March 20265 min read

You set up a company partly so that the business, not you, carries the risk. Then a landlord, a bank, or a supplier slides a personal guarantee across the table, and in a single signature that wall comes down. A personal guarantee is one of the most consequential documents a business owner signs and one of the least understood, because it does not feel like taking on debt, until the day it is called. This briefing explains what you are really promising, and how to sign one with your eyes open rather than closed.

What you are actually promising

A personal guarantee is your promise to pay another party’s debt, usually your own company’s, from your personal assets if the company does not. It reaches past the corporate shield to your savings, and often to your home. Two features make it sharper than people expect. Many guarantees are “all monies” guarantees, covering not just today’s debt but whatever the company may owe in future. And many let the creditor pursue you directly, without first exhausting the company, the moment there is a default.

Where guarantees hide

Guarantees are rarely announced. They sit inside commercial leases, bank facilities, equipment finance, and trade-credit applications, sometimes as a clause deep in a longer document, sometimes on a short form signed in a hurry to open a supplier account. It is entirely possible to have given several personal guarantees over the years and to have lost track of what they cover and whether they still bind you. If you have signed one, a lease is a common place it lives.

How to limit the risk

A guarantee is negotiable like any other term, and several levers can shrink your exposure. Cap the amount, so your liability is limited to a fixed sum rather than open-ended. Limit it to a specific debt rather than “all monies”. Seek a time limit or a release once certain conditions are met. Push back on giving your home as security, and be wary of guaranteeing jointly and severally with others, which can leave you liable for the whole amount if the others cannot pay. Even where a creditor will not move far, understanding the exposure lets you price and plan for it.

Before you put pen to paper

Before signing, get advice, and take special care where the guarantee involves your family home or a spouse who is not part of the business, an area the law treats with particular caution. Ask what the guarantee covers, whether it is capped, how it ends, and what would trigger it. A personal guarantee is often the single line that decides whether a business failure stays with the business, and this is exactly the kind of commitment where early legal advice is cheapest and most valuable.
