Guarantees and indemnities in Uganda
In brief
A contract of guarantee is a promise to perform or discharge the liability of a third person (the principal debtor) if they default (Contracts Act, Cap. 284, s.67). The guarantee provisions run ss.67-86 of the Act, not just the handful of sections often quoted. A guarantor's liability is co-extensive with the principal debtor's (s.70), but the Act gives a guarantor real protections: discharge by an unconsented variance (s.73), by release of the principal debtor (s.74), by a compromise or time-given agreement with the debtor (s.75), by loss of a security the creditor held (s.81), and a guarantee procured by the creditor's misrepresentation is void outright (s.82). Note: s.9(6) requires a guarantee to be in writing, while s.67's own definition says it 'may be oral or written' — an unresolved tension in the text itself; see the grey-areas section.
1. At a glance
What this note covers
A guarantee is a promise to answer for someone else's default. This note covers the full Contracts Act framework for guarantees and indemnities — ss.67 to 86, not the narrower range some summaries quote — the guarantor's co-extensive liability, the many ways a guarantor can be discharged, the practical link to third-party mortgages, and a genuine, unresolved tension in the statute's own text about whether a guarantee must be in writing.
It is written for a creditor taking a guarantee as security (typically a bank or a trade supplier), for a person asked to stand as guarantor, and for the advocates advising either side. It does not cover insurance-type indemnities, performance bonds issued by banks under international guarantee rules, or consumer credit-specific guarantee regulation, which need separate advice.
Statutory references are to the Contracts Act, Cap. 284 (2010 Act 7), consolidated to 31 December 2023 — the section numbers in this Part have not moved between the as-enacted and 2023 consolidated text. Older material that cites only ss.67, 69, 70, 73-75 is not wrong on those numbers, but it is incomplete: eleven further sections in the same Part (ss.71, 76-86) carry genuinely important practitioner-facing rules and are covered in full below.
2. What a guarantee is, and why it matters
Section 67 of the Contracts Act defines a 'contract of guarantee' as a contract to perform a promise or discharge the liability of a third person in case of that person's default. Three roles sit inside every guarantee: the creditor (to whom the guarantee is given), the principal debtor (whose default triggers the guarantee), and the guarantor or surety (who gives the guarantee). A 'continuing guarantee' is one that extends to a series of transactions rather than a single, one-off debt — a running overdraft facility guaranteed for a business, for example, rather than a single loan advance.
A guarantee sits beside, but is legally distinct from, an indemnity. Section 67 defines a 'contract of indemnity' as a contract by which one party promises to save the other from loss caused by the conduct of the promisor or of any other person, and 'indemnity' itself as an undertaking to reimburse another on the occurrence of an anticipated loss. The practical difference is the nature of the liability: a guarantor's liability is secondary and conditional on the principal debtor's default, while an indemnifier's liability is primary and independent — an indemnifier can be liable to make good a loss even if no third party has 'defaulted' in the guarantee sense at all. Getting this distinction right matters at the drafting stage, because the discharge rules that protect a guarantor (ss.73-82, discussed below) do not automatically protect an indemnifier in the same way.
Label the document deliberately
A creditor drafting a security document should decide deliberately whether it wants a guarantee or an indemnity, and say so in the document's own language — not leave the label to be inferred later, when a guarantor is trying to invoke one of the Act's discharge provisions and the creditor is trying to argue the document was really an indemnity all along.
3. The statutory framework: ss.67-86 in full
Part VIII of the Contracts Act, headed 'Indemnity and guarantee', runs from s.67 to s.86 — twenty sections, not the six or seven that a shorthand citation sometimes implies. The framework divides naturally into three groups: formation and basic liability (ss.67-70), discharge of the guarantor (ss.71, 73-83), and the guarantor's own rights once liability crystallises (ss.80-81, 84-86).
Formation and basic liability (ss.67, 69-70)
Section 69 provides that anything done, or any promise made, for the benefit of the principal debtor may be sufficient consideration to the guarantor for giving the guarantee — recognising that a guarantor typically receives no direct benefit themselves; the benefit flows to the principal debtor, and that is enough. Section 70 then fixes the guarantor's exposure: the guarantor's liability is, unless the contract otherwise provides, co-extensive with the principal debtor's liability, and it takes effect only upon the principal debtor's default. A guarantor who has not read the underlying credit agreement is, in effect, agreeing to be bound by terms they may never have seen — which is precisely why the practical-guidance section below insists on reading the principal contract before signing.
Discharge of the guarantor (ss.71, 73-83)
A continuing guarantee may be revoked by the guarantor as to future transactions by notice to the creditor, and the guarantor's death revokes a continuing guarantee as to future transactions, absent an agreement to the contrary (s.71). This is a live, practical protection for anyone who has stood surety for a revolving facility and wants to step out of ongoing exposure without needing the creditor's agreement.
The Act's core discharge provisions then follow a recognisable logic: a guarantor consents to guarantee a specific bargain, and if the creditor and the principal debtor change that bargain, release the debtor, or deal with the debtor in a way that prejudices the guarantor, the guarantor is let out. Section 73 discharges the guarantor from any transaction subsequent to a variance made in the underlying contract without the guarantor's consent. Section 74 discharges the guarantor where the principal debtor is released, or where an act or omission of the creditor discharges the principal debtor. Section 75 discharges the guarantor where the creditor makes a compromise with the principal debtor, or promises to give the debtor time or not to sue, unless the guarantor assents.
Forbearance is not the same as a time-given agreement
Section 76 and section 77 sharpen s.75 with two genuinely useful nuances that are easy to miss. Section 76: a time-extension agreement the creditor makes with a THIRD PERSON (not the principal debtor) does not discharge the guarantor — the protection in s.75 is about the creditor's dealings with the principal debtor specifically. Section 77: mere forbearance to sue the principal debtor — simply not suing yet, without any binding agreement to that effect — does NOT discharge the guarantor. Only an actual, binding time-extension agreement under s.75 discharges; passive delay does not. A guarantor arguing discharge on 'the creditor sat on this for two years' needs to show a real agreement to forbear, not just inaction.
Section 78 provides that releasing one co-guarantor does not discharge the others from their liability, though the released guarantor's own duty to contribute to co-guarantors survives the release. Section 79 discharges the guarantor where an act or omission of the creditor impairs the guarantor's eventual remedy against the principal debtor — a broader, catch-all protection against the creditor doing something inconsistent with the guarantor's position, or failing in a duty the creditor owed the guarantor. Section 81 entitles the guarantor to the benefit of every security the creditor holds against the principal debtor at the time the guarantee was given (whether or not the guarantor knew of it), and discharges the guarantor pro tanto — to the value of the lost security, not entirely — if the creditor loses or parts with that security without the guarantor's consent.
A guarantee procured by misrepresentation is void
Section 82: a guarantee obtained by a misrepresentation made by the creditor, or with the creditor's knowledge and assent, concerning a material part of the transaction, is VOID — not merely voidable, and not merely a discharge as to future transactions. This is the guarantor's strongest weapon where the creditor concealed or misstated something material to induce the guarantee in the first place. Note the gap: the Act addresses misrepresentation only, not a separate concealment ground — do not assert a distinct statutory concealment doctrine exists inside Part VIII; if concealment is the real complaint, it needs to be pleaded as (or alongside) a misrepresentation.
Section 83 addresses conditional joinder: where a guarantee is given on the basis that a co-guarantor will also join, and that person never does, the guarantee is invalid. This protects a guarantor who agreed to share the risk with someone else and never actually got that shared exposure.
The guarantor's own rights (ss.80-81, 84-86)
Once a guarantor actually pays or performs under the guarantee, the Act gives them real rights of recovery. Section 80 subrogates a paying guarantor to all the rights the creditor had against the principal debtor — the guarantor effectively steps into the creditor's shoes. Section 84 goes further and implies, into every guarantee, a promise by the principal debtor to indemnify the guarantor for sums rightfully paid under it — so a guarantor who pays has both a subrogation claim and an independent indemnity claim against the debtor. Sections 85 and 86 deal with co-guarantors: where more than one person guarantees the same debt, they contribute equally among themselves (subject to any different limits they each agreed to be bound by), so a guarantor who pays the whole debt is not left carrying the co-guarantors' share.
How the framework fits together
Read together, ss.67-86 form a coherent, if dense, framework: formation and co-extensive liability (67-70), a long list of ways a guarantor can be let out when the creditor changes the deal or the security behind it (71, 73-83), and a set of recovery rights once the guarantor actually pays (80-81, 84-86). Treat the Part as one integrated scheme when advising either a creditor or a guarantor — a discharge argument under s.73 or s.75 is rarely the whole story once s.79 (impairment of remedy) or s.81 (loss of security) is also in play on the same facts.
4. The writing requirement, and a genuine unresolved tension
Section 9(6) of the Contracts Act provides that 'a contract of guarantee or indemnity shall be in writing', and s.9(7) directs that 'guarantee' and 'indemnity' in that provision take the meaning assigned to them in Part VIII. On its face, this is a clean, mandatory formality rule: no writing, no enforceable guarantee.
s.9(6) versus s.67: an unresolved textual tension
But s.67's own definition of a 'contract of guarantee' describes it as a contract to perform a promise or discharge a third person's liability on default, 'WHICH MAY BE ORAL OR WRITTEN'. Read side by side, s.9(6) says a guarantee shall be in writing; s.67 says a guarantee may be oral. No provision in the Act resolves this tension expressly. As a matter of ordinary statutory construction, a specific formality rule like s.9(6) would typically be read to control over a general definitional clause — but that is this note's own reasoning about how a court would likely resolve the conflict, not a stated judicial resolution, and no case confirming that reading was found in this research. Treat this as a genuinely open textual question and advise accordingly.
The safe practical answer for any advocate is unaffected by which side of that tension eventually prevails: put every guarantee in writing, signed by the guarantor, regardless of the debate about whether an oral guarantee could in principle be enforced. No creditor should rely on an oral guarantee given the live uncertainty, and no advocate should advise a client that an oral guarantee is definitely safe.
5. Guarantees alongside mortgages: the third-party security option
Ugandan bank lending practice frequently combines a personal guarantee with a mortgage over the guarantor's own property, rather than relying on a bare personal promise to pay. The Mortgage Act, Cap. 239 defines a 'surety' as a person who offers security in the form of money or money's worth to ensure payment of monies secured by a mortgage, and expressly includes a guarantor within that definition; it also defines a 'third party mortgage' as a mortgage securing another person's debt (s.2).
In practice this means a guarantor is often asked to do more than sign a guarantee document: the creditor may also want the guarantor's own land mortgaged as a third-party mortgage, giving the creditor a direct proprietary remedy against specific property rather than only a personal claim against the guarantor. This is a materially different — and materially larger — exposure for the guarantor than a pure personal guarantee, because a mortgagee's remedies against mortgaged property (including a power of sale) can move faster and more directly than an ordinary suit on a personal guarantee.
A mortgage alongside a guarantee is a bigger step
A guarantor asked to also execute a mortgage over their own property should treat that as a materially bigger commitment than the guarantee alone, and take independent advice specifically on the mortgage terms — particularly any power-of-sale clause — before signing. See Katende v Barclays Bank below for how contested a power-of-sale clause given alongside a guarantee can become.
One further point should be flagged, not asserted: secondary sources report that s.33 of the Mortgage Act (relief from extortionate mortgage terms) allows a court to order repayment of sums paid 'by the mortgagor or any surety' where mortgage terms are found extortionate. This could not be independently verified against the full primary text in the research for this note. Do not treat s.33 as a general cap on guarantor liability — at most it may be a court remedy embedded in the extortionate-terms jurisdiction, and that is a grey area pending direct verification (see grey areas below).
6. How the courts approach guarantee security
Verified Ugandan case law squarely deciding a commercial guarantee-discharge dispute is thinner than might be expected for such a common commercial instrument. This note reports what was independently confirmed, rather than dressing up a thin record.
Livingstone Katende v Barclays Bank of Uganda
An interlocutory application for a temporary injunction restraining the bank from selling mortgaged property by public auction under a power-of-sale clause that the applicant argued purported to let the bank sell 'without resort to court' — a natural-justice concern about being condemned unheard. The High Court found a prima facie case with a probability of success, held the balance of convenience favoured the applicant given the property's value plausibly exceeding the outstanding loan, and granted the temporary injunction restraining the sale pending trial. This is an interlocutory ruling only — it does not finally decide whether the power-of-sale clause was valid, and costs were reserved to the cause. The applicant had given both a personal guarantee and a legal mortgage for the principal debtor's facility — exactly the third-party-mortgage-plus-guarantee security package described above.
No confirmed Supreme Court outcome to cite
Do not cite a Supreme Court outcome for Katende v Barclays Bank. A secondary source reports an appeal (Barclays Bank of Uganda v Livingstone Katende, reportedly [1994] UGSC 38) said to have 'upheld' the bank's power-of-sale clause — a claim inconsistent with the High Court's own reasoning and which could not be independently confirmed in this research. Cite only the verified interlocutory High Court ruling above, or mention the appeal's existence with its outcome flagged as unconfirmed.
Beyond Katende, one further Supreme Court decision — Banco Arabe Espanol v Bank of Uganda, [1999] UGSC 1 — involves a bank guarantee, but as security for costs in litigation under the Civil Procedure Rules, not as security in a commercial lending relationship. It is not a guarantor-discharge authority and should not be cited for one; at most it illustrates that Ugandan courts accept bank guarantees as valid security-for-costs instruments, which is a different point entirely.
7. Worked example: discharge by variance versus mere forbearance
A guarantor stands surety for a UGX 40 million supplier credit facility extended to a trading company. Eighteen months in, the supplier and the company agree, in writing, to increase the credit limit to UGX 70 million and extend the repayment period — without telling the guarantor. Six months after that, the company misses two payments; the supplier does not sue immediately, waiting another four months while trying to negotiate directly with the company, before finally suing both the company and the guarantor.
Two arguments, only one clearly succeeds
Two separate arguments are available to the guarantor here, and they should not be conflated. First: the written increase in the credit limit and extension of the repayment period is a variance in the underlying contract made without the guarantor's consent — this discharges the guarantor as to transactions subsequent to that variance under s.73 (the original UGX 40 million exposure may remain, but the increased exposure likely does not). Second: the supplier's four months of not suing while negotiating is, on these facts, mere forbearance — not a binding time-extension agreement — and under s.77 that forbearance alone does NOT discharge the guarantor. The variance argument is strong; the forbearance argument, standing alone, is not.
8. Consequences of getting it wrong
For a creditor, the cost of getting guarantee practice wrong is discovering — often years into a facility and after the principal debtor has already defaulted or disappeared — that the guarantee has been discharged by an unconsented variance, a compromise with the debtor, or the release of a security the guarantor was relying on. By the time the discharge is raised as a defence, the creditor has usually lost the practical ability to go back and cure it: the variance already happened, the security is already gone.
For a guarantor, the cost of not understanding s.70's co-extensive-liability rule is agreeing to stand behind a debt whose true terms were never read, and later discovering the exposure is larger, or on worse terms, than assumed. Failing to invoke an available discharge — for example not realising a security was released without consent, engaging s.81 — can mean paying in full when a partial discharge was available.
There is a professional-conduct dimension for the advocate too: drafting a guarantee without addressing which document (guarantee or indemnity) is actually intended, or advising a guarantor client to sign without reviewing the principal contract, risks a negligence claim once the guarantor discovers the scope of what was actually signed.
9. Practical guidance and drafting tips
Writing is always the safe course
Always put the guarantee in writing and have the guarantor sign it personally, whatever view is taken of the s.9(6)/s.67 tension — this is the one piece of advice that is safe regardless of how that unresolved question is eventually settled.
Draft for future variations up front
When drafting for a creditor, build in an express guarantor-consent mechanism for future variations to the principal contract (a simple written-consent clause), rather than relying on the guarantee surviving by accident. This avoids handing the guarantor a s.73 discharge argument every time the underlying facility terms are adjusted.
Read the principal contract, not just the guarantee
When advising a guarantor, always ask for and read the principal contract before the guarantee is signed — s.70's co-extensive-liability rule means the guarantor is agreeing to the terms of a document they may never otherwise see.
10. Common pitfalls
- Citing only ss.67-75 for the guarantee framework and missing the later, practically important sections (s.77 forbearance, s.79 impairment of remedy, s.81 loss of security, s.82 misrepresentation).
- Assuming mere delay in suing the principal debtor discharges the guarantor — it does not, unless it hardens into an actual compromise or time-extension agreement (s.77 versus s.75).
- Letting a security lapse or be released without the guarantor's consent, not realising this discharges the guarantor pro tanto (s.81).
- Treating a mortgage given alongside a guarantee as an identical, interchangeable form of security — a third-party mortgage exposes specific property directly and should be advised on separately.
- Presenting the writing requirement as settled beyond doubt in either direction, when the Act's own text (s.9(6) versus s.67) leaves it genuinely unresolved.
11. Grey areas and points to confirm
The clearest grey area in this note is the tension between s.9(6) ('a contract of guarantee ... shall be in writing') and s.67's own definition of a contract of guarantee ('which may be oral or written'). No interpretive provision in the Act resolves this, and no case confirming a judicial resolution was found in this research. This note's suggestion that the more specific formality rule (s.9(6)) would likely be read to control is this note's own reasoning about ordinary statutory construction — it is not a settled judicial position, and should not be presented to a client as one.
Mortgage Act s.33 (relief from extortionate mortgage terms) is reported by secondary sources to extend to sums paid 'by the mortgagor or any surety', which would be directly relevant to a guarantor who has also given a third-party mortgage. This could not be independently verified against the full primary text in this research (the fetch was truncated before reaching s.33). Do not assert this as a general cap on guarantor liability until independently confirmed.
Ganafa (Kisawuzi) Peter v DFCU Bank Ltd, [2015] UGCommC 182, is a promising but incompletely verified lead: the pleaded facts engage both the discharge-by-variance pattern (s.73) and the compromise/time-given pattern (s.75) — a suit concerning loan sums advanced in excess of, and after, an original credit facility, without the surety's knowledge or consent. The judgment was only partially retrieved in this research and its precise holding on discharge was not confirmed; it is flagged here as a lead worth chasing, not as authority for any specific proposition.
No dedicated Ugandan bank-guarantee statute exists separate from the ordinary Contracts Act Part VIII framework — the Financial Institutions Act, 2004 uses 'guarantee' only inside prudential definitions (exposure, credit accommodation, off-balance-sheet items) rather than as a contract-law provision. Whether international customary instruments such as URDG 758 are generally treated as incorporated into Ugandan bank guarantee practice was not confirmed from any primary source in this research — treat any reference to URDG 758 as a practice point that depends on the guarantee's own terms, not as a default legal rule.
12. Practitioner checklist
- Confirm whether the document intended is a guarantee (secondary liability) or an indemnity (primary liability) and draft it to say so expressly.
- Put the guarantee or indemnity in writing and have it signed by the guarantor personally.
- For a guarantor client: obtain and read the principal contract before signing — liability is co-extensive with the debtor's (s.70).
- For a creditor client: build in an express guarantor-consent mechanism for future variations to the principal contract.
- Before relying on a guarantee in a dispute, check for discharge events: an unconsented variance (s.73), release of the principal debtor (s.74), a compromise or time-given agreement (s.75), loss of a security (s.81), or misrepresentation inducing the guarantee (s.82).
- Do not treat mere delay or forbearance to sue as a discharge event on its own (s.77).
- Where a third-party mortgage accompanies the guarantee, advise on the mortgage terms — especially any power-of-sale clause — separately from the guarantee itself.
