What Happens If A Guarantor Can’t Pay In The UK?

Offering goods or services on credit can be great for winning customers - but it also increases your risk if invoices go unpaid.

That’s why many UK SMEs ask for a personal or corporate guarantee alongside their contracts or credit applications. A well-drafted guarantee can be a powerful safety net.

But what if the guarantor can’t pay when you call on the guarantee? Do you lose your leverage - or do you have other enforcement options? And what can you do in future to prevent this scenario altogether?

In this guide, we break down what happens under UK law when a guarantor can’t pay, your options as the business owed the money, and the legal documents and processes that will help you stay protected from day one.

What Is A Guarantor In Business Contracts (And Why It Matters)?

A guarantor is a person or company that promises to pay a debtor’s obligations if the debtor doesn’t pay. You’ll commonly see guarantees supporting:

• Trade credit and supply agreements
• Commercial leases and equipment hire
• Loan or finance arrangements
• Franchise and distribution agreements

In practice, small businesses often ask a director to personally guarantee a company’s debts, or request a parent company guarantee for a subsidiary. The guarantee may be coupled with an indemnity (which is slightly different - more on that below).

For a guarantee to be enforceable, it’s usually documented as a deed (rather than a simple contract). This avoids issues about whether the guarantor received “consideration” and helps withstand challenges. Make sure you understand the formalities for executing deeds - mistakes here can make enforcement much harder later.

To reduce risk at the outset, many businesses use a tailored Deed of Guarantee and Indemnity and align it with their Terms of Trade. Taking both steps together gives you clear primary obligations (your customer must pay) and a reliable backstop if they don’t.

When A Guarantor Cannot Pay – What Actually Happens?

If your customer defaults and you serve a valid demand on the guarantor, you’ll typically be able to pursue the guarantor for the unpaid amount (plus interest and enforcement costs if your documents allow it). But if the guarantor can’t pay, a few legal realities kick in:

1) Your Rights Depend On The Wording

Guarantees vary. Many include “joint and several liability,” which lets you recover from the debtor, the guarantor, or both - in any order. If there’s also an indemnity, you may have a separate, primary right to compensation for losses caused by the default, even if the underlying debt is disputed or varied.

Well-drafted guarantees will usually state that your rights aren’t affected by granting time to the debtor, releasing security, or other variations. If your guarantee is silent (or drafted poorly), certain changes to the underlying deal could discharge the guarantor.

2) If They Can’t Pay Now, You Can Still Enforce

“Can’t pay” today doesn’t mean “never liable.” You can bring a County Court claim (or High Court for higher value/complex matters) and obtain judgment, then use court enforcement methods to collect over time, such as:

• Charging orders over property
• Third party debt orders (e.g., freezing funds in bank accounts)
• Attachment of earnings orders (for individual guarantors)
• Writs or warrants of control (bailiff enforcement)

If the guarantor is insolvent (or close to it), you may also explore statutory demands and, where appropriate, bankruptcy (individuals) or winding up (companies). These are serious steps - get advice early.

3) Practical Outcomes Often Involve Negotiation

Even with strong legal rights, many businesses choose commercial solutions: payment plans, partial settlements, or swapping in a new guarantor or security. You can document changes using a Deed of Variation or, if you’re replacing parties, a Deed of Novation. Just be careful that any amendment doesn’t inadvertently release your existing rights.

4) Limitation Periods Still Apply

Under the Limitation Act 1980, claims for debt are generally subject to a six-year limitation period (from the date the cause of action accrued). Don’t wait too long to act if a guarantor stops responding.

Your Enforcement Options If A Guarantor Doesn’t Have Funds

When a guarantor doesn’t have cash on hand, think beyond “one demand, one payment.” You have a toolkit - choose the right tools for your situation and risk appetite.

1) Start With The Paper Trail

• Check your Deed of Guarantee and any indemnity wording carefully.
• Confirm you’ve served a valid written demand in the form required.
• Calculate the amount correctly (principal, interest, costs).
• Keep records of all communications and defaults.

A well-drafted deed often requires the guarantor to pay “on demand” and to indemnify you against “all losses, costs and expenses” arising from the default. That clarity helps at every enforcement step.

2) Issue A Letter Before Action

Before you file a claim, send a compliant pre-action letter giving the guarantor a final chance to pay or propose terms. This shows the court you’ve acted reasonably and can prompt swift resolutions. If you need a structure for this, build from a simple letter before action approach tailored to your facts.

3) Court Proceedings And Judgments

If there’s still no payment, you can issue a County Court claim for the guaranteed amount. If the guarantor doesn’t defend, you may obtain default judgment. If they defend, the court will assess the contract, any defences, and your evidence.

Once you have judgment, consider:

• Charging orders: Secure the debt against the guarantor’s property. You can also apply for an order for sale in some cases.
• Third party debt orders: Recover from funds owed to the guarantor by a third party (often a bank).
• Attachment of earnings: Deduct instalments from wages (individuals only).
• Bailiff enforcement: Seize goods to sell towards the debt (practical when assets are available).

4) Insolvency Routes

In appropriate cases, a statutory demand can be a fast way to focus minds. For individuals, non-payment within the timeframe can be a step towards bankruptcy proceedings. For companies, non-payment of a statutory demand may lead to winding up action.

These are high-stakes processes for everyone involved, and you should weigh commercial outcomes, costs, and reputational factors before you proceed.

5) Use (Or Take) Security Where Possible

Where the guarantee is backed by specific security (for example, a legal charge over property, or a debenture), you may enforce that security according to its terms. If you don’t yet have security but are renegotiating, consider requesting a General Security Agreement or a specific charge to improve recovery prospects.

6) Consider Debt Sale Or Agency

If direct enforcement is not economical, you might sell the debt or appoint a collector. If you’re weighing this path, think about the commercial and reputational impacts and whether your contract permits assignment. Our overview on selling debt to a collection agency covers the key legal points to keep in mind.

Common Pitfalls That Can Undermine Your Guarantee

Guarantees are only as strong as their wording and execution. Here are traps that commonly make enforcement harder - and what to do about them.

1) Missing Or Flawed Execution

Guarantees are often executed as deeds. If the deed wasn’t signed correctly (for example, not in accordance with Companies Act 2006 formalities for a company signatory, or without a witness where required), the guarantor may argue it’s invalid. Get your template checked against current deed execution rules and make signing frictionless but compliant.

2) Limited Or Ambiguous Scope

Does the guarantee cover a single invoice, or “all monies” owed now and in future? Is interest included? Are “costs and expenses” recoverable on an indemnity basis? Clarity here can be the difference between full recovery and a fraction.

3) Variations Without Guarantor Consent

Material changes to the underlying contract can sometimes discharge a guarantor if the deed doesn’t say otherwise. If you’re making changes, either ensure your deed permits them without releasing the guarantor or obtain written consent (often via a short variation deed).

4) Overreliance On A Weak Guarantor

If the guarantor has no assets or income, your recovery options narrow. Do diligence before you accept a guarantee: ask for financial statements, property ownership details, and bank references where appropriate. Consider multiple guarantors or caps/thresholds to balance risk and commerciality.

5) Unfair Or Unenforceable Terms

While most guarantees in B2B contexts are judged under general contract principles, terms still need to be reasonable and clear. The Unfair Contract Terms Act 1977 and general law on penalty clauses and reasonableness may bite if obligations are drafted punitively rather than protectively. Keep terms proportionate to the risk you’re covering.

6) Letting Limitation Periods Expire

If you sit on your rights, claims may time out. Diarise the limitation date and use pre-action correspondence to manage timelines sensibly.

How To Reduce Risk Upfront When You Ask For A Guarantee

The best time to protect your business is before problems arise. Here’s how to build a guarantee framework that stands up when tested.

1) Use A Deed Of Guarantee And Indemnity

A combined deed does two important things. The guarantee makes the guarantor liable if the debtor doesn’t pay. The indemnity creates a separate, primary obligation to compensate you for losses arising from the default - which can be easier to enforce if the underlying contract is varied or challenged. A tailored Deed of Guarantee and Indemnity is the gold standard for B2B credit risk management.

2) Align With Your Terms Of Trade

Your guarantee works best when your credit terms, interest provisions, late fees, and enforcement costs are clearly set out in your core Terms of Trade. This reduces scope for disputes about what’s owed and when.

3) Take Security Where Sensible

Guarantees are stronger when supported by security. For company customers, consider a General Security Agreement (a floating charge over assets) or specific charges over key items. For individuals, consider legal charges over property where proportionate and appropriate.

4) Set Caps, Triggers And Reporting

Think commercially about:

• Caps (e.g., maximum liability equal to a set multiple of monthly supply)
• Triggers (e.g., guarantee only required above a credit limit)
• Information covenants (e.g., guarantor to notify you of address changes or adverse events)

Practical guardrails help you protect cashflow without scaring off good customers.

5) Sign Correctly And Keep Copies

Follow the rules for deeds and keep a clean, dated copy. Where you expect to rely on “on-demand” language, make sure the wording is precise. If you use electronic signatures, ensure the witnessing process is handled properly for deeds.

6) Build A Sensible Collections Workflow

Have a standard path: friendly reminder, formal reminder, final notice, letter before action, claim issue, enforcement options. Consistency saves time and costs - and it shows a court you’ve behaved reasonably.

Practical Next Steps If Your Guarantor Can’t Pay Today

If you’re facing a non-paying guarantor right now, here’s a practical, step-by-step path you can adapt.

Step 1: Verify The Debt And The Deed

Confirm the outstanding amount, interest entitlement, and your right to demand payment under the deed. Check execution formalities and any notice requirements (e.g., where to send a demand).

Step 2: Serve A Clear Written Demand

Send a written demand in the form required by the deed, with a clear deadline. Keep proof of service.

Step 3: Assess The Guarantor’s Situation

Quickly gauge whether the guarantor has assets or income. If they’re asset-rich but cash-poor, a payment plan or a charging order strategy may be sensible. If they appear insolvent, consider whether a statutory demand is proportionate.

Step 4: Offer A Short Window To Resolve

Where appropriate, offer a structured payment plan or partial settlement. If you make changes to the underlying agreement or guarantee, document them via a Deed of Variation to preserve enforcement rights.

Step 5: Escalate With A Letter Before Action

If no agreement is reached, issue a formal pre-action letter and set a final deadline. Diarise your limitation period.

Step 6: File A Claim Or Consider Insolvency Options

Issue a County Court claim if needed, then use enforcement methods suited to the guarantor’s profile (property, bank accounts, wages, or bailiff action). In limited cases, weigh bankruptcy or winding up as a strategic option.

Step 7: Consider Commercial Alternatives

If enforcement will be uneconomic, consider whether appointing an agent or selling the debt is a better outcome for your business.

At any point, if the relationship remains important, you might agree to replace the guarantor or take new security - just ensure paperwork and execution are watertight so you don’t waive rights accidentally.

Key Takeaways

• If a guarantor cannot pay on demand, you still have strong options: court claims, judgments, and targeted enforcement methods can recover funds over time.
• Your rights turn on the wording and execution of your documents. A combined Deed of Guarantee and Indemnity aligned with robust Terms of Trade is the best foundation.
• Think commercially: early negotiation, payment plans, or taking/replacing security can deliver faster, lower-cost outcomes than litigation.
• Avoid common pitfalls by executing deeds correctly, keeping the scope clear, obtaining consent for material variations, and monitoring limitation periods.
• Build a collections workflow that escalates from reminders to a compliant letter before action, then claims and enforcement where needed.
• For higher-value or repeat credit, consider security such as a General Security Agreement and ensure any amendments are captured in a Deed of Variation.
