The Guarantee in the File: Auditing Director Security Before You Extend Credit

When a limited company asks for trade credit, the credit application often contains more than a request for terms. Buried among the company details, bank references and terms and conditions may be a personal guarantee signed by a director. Suppliers tend to focus on the customer's accounts and payment history. The guarantee is frequently treated as a formality until the day the company stops paying and the file is reopened in a hurry.

That is the wrong order of events. A personal guarantee can be a valuable second route to recovery, but it is not a magic remedy. Its value depends on how it is drafted, whether it has been properly executed, whether the guarantor has assets and whether the supplier follows the correct procedure when demand is made.

What a personal guarantee actually does

A personal guarantee is a separate promise by an individual, usually a director, to meet the liabilities of a company if the company fails to pay. It sits alongside the company's own obligation. It does not turn the supplier into a secured creditor, and it does not remove the need for ordinary credit control. It simply gives the supplier another defendant if the company does not pay.

The commercial effect depends heavily on the wording. A guarantee may be limited to a specific contract or capped at a fixed sum. It may be a continuing guarantee covering future invoices and liabilities. It may be given jointly and severally by more than one director, allowing the supplier to pursue any one of them. It may also be an indemnity, which is a distinct legal mechanism with different risk implications. Suppliers should read the clause before extending meaningful credit, not after the account is in arrears.

What makes one enforceable

In England and Wales, a guarantee generally must be in writing and signed by the guarantor to be enforceable. Where the document is executed as a deed, additional formalities apply, such as witnessing. Scotland and Northern Ireland have their own requirements, so cross-border cases need specific advice.

Enforceability is not only about signature. The guarantee should identify the parties and the obligations clearly. It should show that consideration has been given, or be executed as a deed. It should set out whether the guarantee is capped, whether it is continuing, how demand must be made and which law and jurisdiction apply. If the guarantee was obtained by misrepresentation or undue influence, or if the guarantor did not understand what was being signed, its enforceability may be challenged.

Independent legal advice is not a universal statutory requirement for a director's guarantee, but it is prudent. A supplier that encourages the guarantor to take advice, and records that encouragement, reduces the risk of a later complaint that the guarantee was signed without understanding. It also makes the document look more deliberate, which is useful if the supplier ever has to rely on it.

A pre-signature checklist

Before accepting a director's guarantee, a supplier should work through a short checklist and keep a record of the answers.

1. Identify the guarantor precisely: full legal name, address and capacity. Confirm that the individual is a director or otherwise authorised to give the guarantee.
2. Confirm the scope: does the guarantee cover all liabilities, a specific contract, or a capped amount? Does it include interest, costs and enforcement expenses?
3. Check duration and revocation: is it a continuing guarantee? Can the guarantor withdraw it, and if so, how much notice is required?
4. Read the demand mechanics: must demand be in writing? Is a notice period required? To which address must it be sent?
5. Check execution: is the document signed and dated? If it is a deed, has it been witnessed correctly? Are there counterpart signature pages?
6. Consider the guarantor's financial position: a guarantee is only as good as the assets behind it. Prior guarantees, insolvency risk and personal borrowing all matter.
7. Record legal advice: invite the guarantor to take independent advice and note that invitation on file.
8. Store the original and diary a review. Guarantees should not disappear into a scanned credit file with no owner.

A guarantee should also be proportionate. An unlimited, continuing guarantee may be appropriate for a large credit line, but it is a significant personal commitment. A supplier that understands the difference between a capped guarantee and an open-ended one is better placed to decide what level of credit it is prepared to offer.

When the company stops paying: a measured escalation

The first rule is that the guarantee must not become an excuse to relax credit control against the company. The supplier should continue to issue statements, chase the debt and preserve evidence of supply and non-payment. The guarantee is an additional route, not a replacement.

Once the company has failed to pay after formal demand, the supplier should check the guarantee's trigger conditions. Some guarantees require a written demand to the guarantor; others require notice to the company first. The supplier should follow the wording precisely and keep a copy of every letter.

A formal demand to the guarantor might read as follows:

Dear [Guarantor],

We refer to the personal guarantee dated [date] given by you in respect of [Company]. Despite written demand dated [date], the sum of £[amount] remains unpaid. Under clause [reference], you are liable to pay that sum on demand. We require payment by [date, allowing a reasonable period such as 14 days]. If payment is not received, we will consider legal proceedings without further notice. This letter is sent without prejudice to our rights under the guarantee and at law.

A few practical points follow from that script. The supplier should not accept a vague promise of payment without a clear date. It should not alter the guarantee informally or suggest that it is waiving rights unless it has taken advice. If the guarantor disputes the debt, the supplier should separate the dispute from the demand and seek legal advice before issuing proceedings or a statutory demand.

The guarantee is only useful if it is usable

A director's guarantee is not a substitute for sensible credit terms, deposits or stage payments. It is a secondary layer of protection. The time to test it is before credit is granted: read the clause, check the execution, confirm the cap and keep the original. When a limited company customer stops paying, that preparation can turn a buried clause into a practical route to recovery rather than a disappointing piece of paperwork.
