A guarantee dispute starts with the signed promise, not the loan balance
A Kenyan creditor may have a clear debt against a borrower yet fail against a guarantor because the guarantee was not proved, the claim exceeded its scope, a required demand was not made, or later dealings changed the risk. Conversely, a guarantor cannot escape a signed obligation merely by saying that the borrower should be pursued first when the document permits direct recourse.
The guarantee must be analysed as a separate contract. Identify the creditor, principal debtor, guarantor, guaranteed obligations, maximum liability, duration, conditions, notices and governing transaction. Then reconstruct what happened after signature: advances, variations, indulgence, payments, security releases, settlements and demands.
This guide addresses contractual guarantees and surety disputes connected with Kenyan civil debt recovery. It does not cover statutory bail bonds, insurance bonds, performance bonds with materially different wording, or enforcement of a registered charge. Start with the loan-repayment guide where the primary dispute is the borrower’s account rather than the surety’s separate liability.
First prove a guarantee that Kenyan law can enforce
Section 3(1) of the Law of Contract Act provides that no suit may be brought on a promise to answer for the debt, default or miscarriage of another unless the agreement, or a memorandum or note of it, is in writing and signed by the party to be charged or a lawfully authorised person. Locate the executed instrument, not only an unsigned template or later account statement.
Check signature and capacity. If an individual signed, compare the signature page, identity details and witnessing or delivery evidence. If a company guaranteed, obtain board or delegated authority records and verify who signed for it. A director who signs only for the borrowing company does not necessarily assume personal liability; the signature block and entire document must show the capacity intended.
Preserve the complete execution trail: original or reliable copy, covering email, board resolution, witness details, version history and delivery record. Where electronic material is relied on, sections 106A and 106B of the Evidence Act govern admissibility of electronic records and the statutory conditions should be addressed. Do not present a cropped signature image without the document to which it was attached.
Decide whether the promise is a guarantee, an indemnity or both
A guarantee ordinarily answers for another person’s obligation; an indemnity may create a primary promise to protect the creditor against specified loss. Commercial documents often contain both concepts, but the label is not conclusive. Read the operative clauses to determine what triggers payment and whether liability depends on enforceability of the borrower’s debt.
Map defined terms carefully. “Obligations,” “secured liabilities,” “facility,” “borrower” and “finance documents” may expand or narrow the promise. Check whether future advances, renewed facilities, interest, default charges, legal costs and enforcement expenses are included. If there is a monetary cap, identify whether interest and costs sit inside or outside it.
A continuing guarantee can cover a running account or successive transactions, but its duration still comes from the wording. Look for termination rights, a notice period, a final-account clause and treatment of liabilities incurred before termination. A resignation as director or shareholder does not by itself cancel a separate continuing guarantee.
Reconstruct the guaranteed account independently
Prepare a transaction-level account from the original advance or supply. Separate principal, contractual interest, default interest, fees, recoveries, security proceeds and credits. Identify every facility document and variation. The creditor should be able to reproduce the amount claimed without relying on one unexplained certificate or demand figure.
Compare each component with the guarantee. A surety may cover one facility but not a later overdraft; a capped guarantee may exclude sums above the cap; recovery costs may require express wording. Payments and asset-sale proceeds must be credited once. A claim against borrower and guarantor may proceed in parallel where legally permitted, but it cannot yield double recovery.
Under sections 107 to 109 of the Evidence Act, the party asserting facts generally bears the relevant burden of proof. The creditor therefore needs the signed guarantee, underlying agreement, account and trigger evidence. A guarantor alleging payment, forgery, agreed release or another particular defence should preserve the documents and witnesses supporting it.
Read the trigger and demand clauses literally
Some guarantees make liability arise on the borrower’s default; others require a written demand in a particular form; some combine default, notice and expiry of a payment period. Identify the exact trigger before sending a generic demand. If notice must go to a stated address, by a specified method or with an account, comply and keep proof.
A sound demand identifies the instrument, borrower, default, guaranteed amount, calculation date, contractual basis, payment deadline and delivery method. It should not demand the borrower’s entire balance if the guarantee is capped or narrower. The demand-letter guide explains how to construct an open claim and preserve service evidence.
Where the document permits direct demand, the creditor may not need to exhaust remedies against the borrower first. Where wording or another agreement imposes a sequence, that condition matters. Neither side should rely on a general assumption about “first suing the company”; the signed terms and any controlling law decide.
Test later variations, indulgence and security dealings
List every material change after the guarantee: increased limit, new facility, extended maturity, altered interest, replacement borrower, additional advance, settlement or restructuring. Then check whether the guarantor consented in writing and whether the guarantee anticipated the change. A boilerplate consent to indulgence should be read in context rather than treated as unlimited authority to rewrite the commercial risk.
Distinguish temporary forbearance from a binding alteration. A creditor may delay enforcement, but a formal settlement can compromise, suspend, replace or release rights. The debt-settlement guide explains why the agreement must state what happens to guarantees and security on performance and default.
Review collateral events. If the creditor released, impaired or sold security, record authority, valuation, proceeds and allocation. The effect on the guarantor depends on the instrument, the transaction and applicable surety principles. A guarantor challenging impairment needs evidence of the security, the creditor’s act and the resulting prejudice; a creditor needs a transparent realisation account.
Examine consent, misrepresentation and independent understanding
A guarantor may allege that the nature of the document was misrepresented, a signature was forged, material information was concealed, or influence made consent improper. These are fact-sensitive allegations. Preserve drafts, meeting notes, language assistance, advice records, identity checks and communications with the borrower and guarantor.
Do not assume that a family or business relationship proves invalidity, but do not ignore a transaction that appears inexplicable for the guarantor. Was the document presented as a witness form when it created personal liability? Did the creditor know the borrower was making a false explanation? Was the guarantor given the final version and opportunity to obtain advice? The evidence should answer those questions.
A creditor should avoid overstating the effect of an “independent advice” acknowledgment if no advice was actually given. A guarantor should not sign an acknowledgment without understanding it. Clear onboarding evidence reduces later disputes but cannot cure an instrument that fails the statutory writing and signature requirement.
Limitation depends on the promise and its trigger
Section 4(1) of the Limitation of Actions Act generally provides a six-year period for actions founded on contract. The accrual date in a guarantee case depends on the legal character and wording of the obligation, including whether demand is a condition. Record the borrower’s default, acceleration, demand, expiry of notice, payment and any acknowledgment rather than assuming time runs from the facility’s first missed instalment.
A creditor should calculate limitation before negotiation consumes the remaining period. A guarantor should obtain the complete chronology. Correspondence marked “without prejudice,” a request for time and a part payment can have different evidential or legal significance; do not assign an effect without reviewing the words, authority and statute.
Choose pleadings and remedies that match the dispute
The claim should plead the written guarantee, signature or authority, guaranteed transaction, borrower’s default, contractual trigger, demand where required, calculation and relief. Attach or identify the relevant documents under the applicable procedure. If the guarantor genuinely disputes execution or scope, summary treatment may be inappropriate until that issue is resolved.
Potential relief includes the guaranteed sum within the cap, contractually supported interest, recoverable costs, declarations about liability, or accounts of security proceeds. The guarantor may seek dismissal, a declaration of discharge or limitation, rectification where legally available, or credit for payments and realised security. Remedies depend on pleaded facts, not a standard checklist.
After judgment, enforcement follows the decree against the liable party’s property or debts. The judgment-enforcement roadmap explains asset disclosure, garnishee proceedings and attachment. Keep the borrower, each guarantor and each security account reconciled so that one recovery is credited across the connected liabilities.
Prepare a dispute file that exposes the real issue
Arrange the file in five sections: formation; guaranteed transaction; later changes; default and demand; recoveries and balance. Add a one-page chronology and clause map. This organisation quickly shows whether the dispute concerns signature, authority, scope, trigger, discharge, limitation or arithmetic.
For settlement, specify the admitted amount, disputed issues, payment source, treatment of other obligors and security, release condition and default effect. A release of the borrower may affect recourse against a guarantor; a payment by a guarantor may generate contribution or reimbursement questions. All affected rights should be addressed expressly.
Request a Kenyan guarantee-dispute review with the signed guarantee, facility or supply contract, account, variations, security records, demands, proof of service, payment history and authority documents. The review should identify the enforceable promise and test every amount and later transaction against it.
Frequently asked questions
Must a guarantee be in writing to be sued on in Kenya?
Yes. Section 3(1) of the Law of Contract Act requires the agreement, or a memorandum or note of the promise to answer for another person’s debt, default or miscarriage, to be in writing and signed by the party to be charged or a lawfully authorised person.
Must a Kenyan lender sue the borrower before demanding payment from a guarantor?
Not invariably. The answer depends on the guarantee’s trigger and any related agreement. Some instruments permit direct recourse after default and demand; others impose conditions or sequencing. The creditor must prove compliance with the actual signed terms.
Can changing the underlying loan affect a guarantor’s liability?
It can. The effect depends on the nature of the change, the guarantee wording, any advance consent and applicable surety principles. The parties should compare every increase, extension, restructuring or replacement facility with the risk the guarantor agreed to assume.
