It usually starts with a favour. A sibling needs a business facility. A colleague needs a car loan. A spouse's company needs working capital. The bank asks for a guarantor, the papers look routine, and the conversation is framed as temporary support - just until the loan is cleared.
Months or years later, the borrower defaults. Your phone starts ringing. A demand letter arrives. Suddenly the bank is not speaking to the borrower - it is speaking to you.
If that situation feels familiar, you are not alone. Guarantor disputes are among the most stressful banking problems we see, because they mix family loyalty with personal financial risk. This note explains, in practical terms, what a loan guarantee does under Kenyan practice, what you should check before signing, and what to do when the bank is already after you.
What you actually agreed to
A guarantee is not a character reference. In most bank documents, it is a binding promise that if the borrower does not pay, you will. Depending on the wording, the bank may treat you as jointly and severally liable - meaning it can pursue you for the full outstanding amount, not just a share, and often without first exhausting every remedy against the borrower or the borrower's security.
Many guarantees are also framed as on demand. That language matters. It can allow the bank to call on you once it issues a compliant demand, rather than waiting for a long court process against the principal debtor. The exact position always turns on your specific documents - but the working assumption should be: if you signed, your assets may be on the line.
What to check before you guarantee a loan
Before you sign - or before you renew or expand an existing facility - ask for the full pack, not just the signature page. At minimum, press for clarity on the following.
1. Cap and exposure. Is your liability limited to a fixed amount, or is it open-ended (principal, interest, fees, costs, and all monies)? Open-ended language can grow far beyond the figure you thought you were supporting.
2. Continuing vs one-off. A continuing guarantee can cover future borrowings and top-ups unless it is properly terminated. Ask whether today's signature also covers tomorrow's facilities.
3. Joint and several liability. If there are co-guarantors, can the bank pick the person with the most reachable assets - including you - for 100% of the debt?
4. Security already in place. What collateral does the bank hold over the borrower (land, vehicles, receivables, debentures)? A guarantee should be a backstop, not a substitute for proper security - yet banks still rely on guarantors heavily.
5. Your own security and family property. Are you being asked to charge land, shares, or deposits? If matrimonial or family property is involved, spouse consent and proper advice are not optional formalities.
6. Information rights. Will the bank tell you if the borrower falls into arrears? Many guarantors only learn of trouble when demand is already high. Ask for notice clauses and a practical reporting arrangement.
7. Variation and restructuring. Can the bank extend, restructure, or increase the facility without your fresh consent? Standard forms often try to preserve your liability even when the deal changes.
8. Independent legal advice. If the borrower benefits and you do not, treat that as a red flag for pressure. Get advice from a lawyer who is not acting for the bank or the borrower.
9. The borrower's ability to repay. Ask for the basics: purpose of the loan, repayment plan, existing debts, and what happens if the business fails. Loyalty is not a credit assessment.
If the bank is already after you
Do not ignore demand letters, auction notices, or court papers. Silence rarely helps. At the same time, do not rush into admissions, payment plans, or further security until you understand the paperwork.
Practical first steps:
Get the documents. Ask the bank (in writing) for copies of the facility letter, guarantee, any security documents, statements of account, and the demand itself. You cannot assess exposure without the numbers and the contract.
Check the arithmetic. Confirm principal, interest, penalties, fees, and how the balance was calculated. Errors and opaque charges are common pressure points.
Test the demand. Was demand properly issued under the contract? Was it served on the right person? Timing and form can matter.
Look for discharge or reduction arguments. Depending on the facts and the wording, issues can include material variation of the facility without consent, release of security that prejudiced you, payment already made, limitation, or defects in how the guarantee was taken. Bank standard forms try to close many of these doors - which is why the documents must be read carefully, not assumed.
Consider co-guarantors and the borrower. If you pay, you may have rights of recourse against the borrower and contribution claims against co-guarantors. Those rights are valuable, but they are not automatic cash in hand - they need strategy.
Negotiate from a position of information. Banks sometimes prefer a structured settlement, refinance, or timed payment plan to a messy enforcement fight - especially where security realisation will be slow. Negotiation works better when you know your contractual weak points and theirs.
Myths that get guarantors into deeper trouble
The bank must sell the borrower's land first. Not necessarily. Many guarantees allow parallel pursuit of the guarantor.
I only guaranteed a small part. Joint and several wording can still expose you to the whole debt.
They are family - they will sort it. The bank's contract is with you. Family assurances do not bind the lender.
If I pay something, the problem pauses. Partial payments without a clear written standstill or settlement can still leave the rest running - with interest.
When to get counsel quickly
Seek advice promptly if you have received a formal demand, statutory notice, auction notice, or summons; if you are being asked to sign a fresh guarantee, restructuring, or additional security under pressure; or if land, a family home, or business assets are at risk. Early review is usually cheaper than crisis litigation.
At ZMS Legal, we advise guarantors and borrowers on facility documents, demand responses, negotiated exits, and enforcement disputes. If you are already facing bank pressure, bring the demand letter and whatever documents you have - even incomplete packs are a starting point.
