Surety Agreement Nigeria: How a Guarantor Can Lose Their Property (2026)

What a surety agreement actually creates

A surety agreement binds three parties: the creditor, the principal debtor, and the surety (guarantor). The surety's promise is accessory — it tracks the principal obligation — but that does not make it minor.

Under Nigerian common law (inherited from English equity), a surety is bound from the moment the creditor acts in reliance on the guarantee. The guarantee is enforceable even if the surety did not personally benefit from the transaction. Courts in Nigeria have consistently held that benefit to the principal debtor is sufficient consideration for the surety's promise.

The distinction that matters most is whether the guarantee is secondary or joint-and-several.

Secondary liability vs joint-and-several — the gap that catches sureties off-guard

A secondary guarantee means the creditor must exhaust remedies against the principal debtor first. The surety is a fallback. This is the arrangement most people assume they are signing.

A joint-and-several guarantee means the creditor can proceed directly against the surety, ignoring the principal debtor entirely, the moment default occurs. No demand on the principal, no suit, no waiting. Many commercial bank guarantees in Nigeria are drafted this way — the operative phrase to look for is "as principal debtor and not merely as surety."

When a guarantor signs a joint-and-several instrument, the creditor's lawyers do not need to chase the borrower first. They can file in the High Court against the guarantor, obtain summary judgment, and proceed to enforcement — all before the principal debtor's assets have been touched.

How creditors enforce against a guarantor's property in Nigeria

Enforcement follows the standard civil procedure route. After obtaining judgment in the relevant State High Court or the Federal High Court (where the creditor is a financial institution regulated federally), the creditor applies for a writ of execution.

Nigerian courts can order:

• Attachment of land — the Land Use Act 1978 does not prevent enforcement; a charge or court order can give the creditor a path to the Commissioner of Lands for a vesting order or forced sale.
• Garnishee proceedings — bank accounts held in the guarantor's name are frozen and transferred to the creditor.
• Writ of fifa — movable property (vehicles, equipment, stock) is seized by the Sheriff and auctioned.

Where the guarantee is secured by a registered debenture or legal mortgage, the creditor can appoint a receiver under the security agreement without returning to court at all. That receiver then operates or disposes of the charged assets.

Land is often the most painful loss because its value frequently exceeds the debt — yet the process is the same. A guarantor who charged a family compound as security for a business loan can lose that property to satisfy the debt in full, including interest and the creditor's legal costs.

The subrogation right most guarantors never use

After a guarantor pays the creditor, Nigerian equity gives the guarantor the right of subrogation: stepping into the creditor's shoes to recover from the principal debtor. The guarantor inherits every security interest the creditor held — mortgages, charges, collateral — and can enforce them.

This right is not automatic in the sense that a guarantor must act promptly. If the creditor released the principal debtor's security before the guarantor paid, the guarantor's subrogation claim may be diminished or lost entirely.

Subrogation is worth knowing about before signing, not after. A guarantor who understands this right should insist that the creditor preserve all securities against the principal debtor throughout the loan term. Courts in Nigeria have recognised that a creditor's negligent or deliberate release of co-security discharges the surety to the extent of the prejudice caused.

Discharge clauses — when a surety is released from liability

A guarantee can be extinguished in full or in part by several events. Nigerian courts apply English equitable principles here, which the Nigerian court system absorbed through the received English law framework.

Material variation of the underlying contract. If the creditor and principal debtor change the loan terms — extending the repayment date, increasing the interest rate, or altering the scope of the obligation — without the surety's written consent, the surety is discharged. The rationale: the surety agreed to a specific risk, not to whatever risk the parties later create.

Giving time to the principal debtor. Where the creditor formally agrees to give the principal debtor extra time to pay and does so without the surety's consent, the surety is discharged under the rule in Holme v Brunskill (which Nigerian courts apply). Many modern bank guarantees attempt to negate this by including a "time given" clause — so check whether yours does.

Release of co-sureties. If two people guarantee the same debt and the creditor releases one, the other is discharged pro tanto (to the extent that the discharged co-surety would have contributed under the right of contribution between co-sureties).

Creditor's failure to register the guarantee. Where applicable legislation requires registration (for example, in a company lending context under the Companies and Allied Matters Act 2020, a charge must be registered within 90 days of creation), failure to register can affect the creditor's priority — but it does not automatically discharge the personal guarantee.

The practical point: discharge clauses are defences, and defences must be raised. A guarantor who does not file a defence or engage competent counsel will likely lose by default judgment.

What a well-drafted surety agreement must contain

A surety agreement for Nigeria should include — at minimum — the following:

• Exact definition of the principal obligation: the loan amount, interest rate, and repayment schedule the surety is covering.
• Cap on liability: "guaranteed up to ₦X, inclusive of interest and costs" limits exposure to a known ceiling. An uncapped guarantee is open-ended.
• Notice requirements: the surety should receive written notice of default within a specified number of days before the creditor can call on the guarantee.
• Consent to variation clause — or its deliberate exclusion with a separate initialled acknowledgment.
• Security description: if the guarantor charges a property, the registered title number and full description must appear.
• Duration: perpetual guarantees are enforceable but a defined term limits how long the exposure runs.

Absent a cap clause, a guarantor who signed for a ₦10 million loan can be held for ₦10 million in principal plus accrued interest at the contractual rate, penalty charges, and litigation costs — a figure that can easily exceed double the original advance.

Common scenarios where sureties lose

Scenario 1: The silent SME loan. A company director signs a personal guarantee for a corporate loan. The company restructures, the bank agrees to a revised repayment plan (without notifying the director/guarantor), the company later fails entirely. The bank then sues the director personally. Whether the restructuring constitutes a material variation sufficient to discharge the guarantee will depend on the specific language of the "consent to variation" clause in the guarantee document.

Scenario 2: Co-signatory on a tenancy bond. A parent signs as surety on a son's commercial lease. The son abandons the premises mid-term. The landlord's losses — unpaid rent plus refurbishment — are claimed against the parent under the surety clause in the lease. Nigerian courts treat these clauses the same way as loan guarantees.

Scenario 3: The bail bond surety. In criminal matters, a person who stands surety for an accused's bail undertakes to pay the court-ordered sum if the accused absconds. Courts have ordered forfeiture of cash deposits and property bonds where accused persons fail to appear. This is a statutory process under the Administration of Criminal Justice Act 2015.

Steps to take before signing

1. Ask for the full loan facility letter, not just the guarantee document. Understand what you are guaranteeing.
2. Identify whether the instrument is joint-and-several. If it is, you have the same exposure as the principal debtor.
3. Negotiate a monetary cap. Most commercial creditors will accept one.
4. Insert a notice-of-default clause giving you the right to cure the default before enforcement proceeds.
5. Have a solicitor review the discharge and variation clauses specifically — these are where sureties lose defences they never knew they had.

Being asked to sign as a guarantor is not a formality. It is a personal financial commitment that, in a worst case, ends with a court ordering enforcement against assets you have spent years building.
