What a guarantor is, in law

A guarantor on a Kenyan credit contract is a person who signs to promise the lender that they will pay the debt if the primary borrower does not. That promise creates a direct legal obligation between the guarantor and the lender, independent of the borrower's promises. The guarantor is not an intermediary, not a witness, not a character reference. They are, in a real sense, a co-liable party.

On a boda loan, the guarantor requirement is standard for the two dominant asset financiers, Watu Credit and Mogo Auto, and near-universal on SACCO-issued transport loans. The guarantor is typically another rider, a family member, or in some SACCO structures a fellow member with existing shares.

What Watu terms specifically say about the guarantor

Watu Credit's summarised customer terms include a provision that, if the primary borrower defaults and the bike is repossessed and sold at market value, any shortfall between the sale proceeds and the outstanding balance can be pursued against the borrower or the guarantor [Source 1]. This is not the same as "the borrower is pursued first, and the guarantor only if the borrower cannot be found." It is a joint-and-several style position: Watu can choose to pursue whichever party is easier to recover from.

In practice, that often means the guarantor. Guarantors are usually chosen because they are more traceable and more contactable than the primary borrower (family address, employer, SACCO membership). If the primary borrower has disappeared into another town or another line of work, Watu's recovery incentive is to pursue whoever is left standing.

The five common misconceptions

  1. "I only signed as a witness." The signature block on the Watu, Mogo or SACCO form is labelled. If it says "Guarantor" anywhere near your signature line, you are a guarantor. Witness sections are usually explicitly labelled "Witness" and are separate.
  2. "I signed but I never got a copy so it does not count." A signed contract binds even if you were not given a copy. If you signed and were not given a copy, you should request one now.
  3. "I can withdraw whenever I want." No. Guarantorship survives until the debt is fully settled or the lender explicitly releases you.
  4. "They cannot come after me if the bike is sold." They can, if the sale proceeds fall short of the outstanding balance [Source 1].
  5. "I will only be in trouble if I actually take out the loan myself." No. Default on a debt you guaranteed can put you on CRB for up to 5 years under the CBK Credit Reference Bureau Regulations, 2020 [Source 2], with all the borrowing consequences that flow from that listing.

What to ask before you sign as a guarantor

If you are being asked to guarantee someone's boda loan, ask the following in writing before you sign. If any of the answers are unavailable, do not sign.

  1. What is the total repayment I would be liable for if the borrower defaulted tomorrow? Not the weekly instalment, the full balance.
  2. What is the market-value shortfall estimate? If the bike is repossessed and sold at typical dealer wholesale (approximately 40 to 60 percent of dealer new price, illustrative), what is my worst-case exposure?
  3. Is there a co-guarantor? If there is, and the terms make you both jointly-and-severally liable, understand you may still be pursued for the full amount even if the other guarantor also signed.
  4. What is the primary borrower's current CRB status? Anyone already CRB-listed is a higher default risk. If they were denied elsewhere, that is why they need a guarantor.
  5. What is the borrower's realistic weekly earnings against the weekly instalment? See the arithmetic on daily earnings vs daily repayment. If the borrower cannot show a healthy margin, you are the underwriter of last resort.
  6. Do I have written confirmation that I will be notified if the account goes into arrears? Some lenders do not proactively notify guarantors of early-stage arrears; a written commitment protects you against being surprised at day 30 or day 60.

What to do if the borrower is now in default

You are hearing about it either from Watu (a collections call to the guarantor, typically starting once arrears have built) or from the borrower directly. Take these steps in order:

  1. Confirm in writing exactly where the account stands. Ask Watu for the current outstanding balance, current arrears, the date of the last payment, and whether the bike has been repossessed or is about to be. See our Watu default guide for the process.
  2. Establish what the primary borrower can pay. If they can catch up on arrears themselves, your role is to help them do that fast, not to pay it for them. Paying it yourself resets nothing about the underlying arrangement, and it teaches the borrower that you will absorb the shortfall.
  3. If repossession has happened, understand the seven-day redemption window. See the redemption guide. Redemption is arrears + KES 5,000 charge, not just the missed instalment.
  4. If the bike is being sold, expect to be pursued for the shortfall. See the shortfall guide. The shortfall can easily be tens of thousands of shillings, and you are on the hook alongside the borrower.
  5. Get everything in writing. Verbal assurances from a collections agent are not binding. A settlement figure quoted verbally at the branch is not enforceable. Insist on written statements and keep copies.
  6. Verify the lender. If the collector is claiming to be acting for Watu, verify against Watu customer care. Watu itself is CBK-licensed as a non-deposit-taking credit business; check any adjacent claimant at our CBK licence checker [Source 3].

CRB consequences for guarantors

A guarantor who is pursued for the shortfall and does not settle can be listed on the Credit Reference Bureaus in their own right. Under the CBK CRB Regulations, 2020 [Source 2], a negative listing typically stays on file for 5 years from the date of the default event. That listing affects the guarantor's ability to borrow from any CBK-reporting lender for years, potentially blocking the guarantor from mortgage, asset finance, credit card, and digital lender access. See how to get off CRB in Kenya for clearance mechanics.

Regulatory framing

Watu Credit Ltd is CBK-licensed as a non-deposit-taking credit business (licensed 5 June 2025, per the April 2026 CBK register [Source 3]) following the Business Laws (Amendment) Act No. 20 of 2024 in force 27 December 2024, which brought asset finance under CBK supervision. Section 33S carries penalties of up to 3 years imprisonment or KES 5 million for unlicensed operation. A CBK-licensed lender is bound by consumer-protection expectations, but a guarantor's underlying contractual liability under the guarantee remains enforceable, regardless of whether the lender's recovery tactics are up to standard.

FAQ

What am I actually liable for as a boda loan guarantor?

For the full outstanding balance if the primary borrower defaults. On Watu specifically, if the bike is repossessed and sold at market value and the sale falls short of the balance, Watu's summarised customer terms allow Watu to pursue the guarantor for the shortfall.

Am I liable if I only signed as a witness?

It depends on what you signed. A witness signs to confirm identities were verified; a guarantor signs to accept liability. The distinction sits in the contract text, not in the informal description at the branch. If you signed a section headed "Guarantor" or you signed alongside "guarantor undertakings," you are a guarantor, not a witness.

Can I withdraw as a guarantor if the borrower is up to date?

Not unilaterally. Guarantorship survives until the debt is fully settled or the lender explicitly releases you. Even if the borrower has paid faithfully for a year, you remain exposed until the final payment clears.

What happens to my CRB record if the person I guaranteed defaults?

Watu and other CBK-licensed lenders can list guarantors on the Credit Reference Bureaus for the guaranteed debt. A default on a debt you guaranteed can put you on CRB for up to 5 years under the CBK Credit Reference Bureau Regulations, 2020.

Can I be pursued if the primary borrower dies?

Yes. Guarantorship typically survives the borrower. The lender can pursue the guarantor for the balance regardless of what happens to the primary borrower.
