Chasing an Unpaid Invoice in Kenya: Demand Letter to Small Claims, Explained

February 2026 · Debt Recovery & Small Claims · 7-minute read

They got the work. They signed the delivery note. They promised to pay Friday. It is now three months later, your calls go to voicemail, and they have not replied to a single WhatsApp message. You are owed money. They know it. And they are betting you won’t do anything about it.

The bet pays off more often than it should. Most Kenyan SMEs — and most individuals — never formally pursue unpaid debts. They assume the process will be slow, expensive, and ultimately futile. They write off the money as a loss and move on.

That assumption is wrong. And in a business environment where cash flow is the difference between surviving a quarter and not, it is an assumption that can be fatal.

Kenya has a legal system specifically designed for this problem. The Small Claims Court, established under the Small Claims Court Act No. 2 of 2016, handles disputes up to KES 1,000,000. The Adjudicator must deliver a decision within 60 days of filing. Filing costs KES 1,000. And the judgment, when you win, is enforceable with the full power of the court behind it.

"Most debtors are not counting on your patience. They are counting on your inaction. A demand letter tells them the inaction is over."

Why the Demand Letter Comes First — and Why It Actually Works

Before any court action, before any filing, there is the demand letter. It is not a formality. It is often the most effective tool in the recovery process — and it costs you almost nothing to send.

A properly drafted demand letter from an advocate does three things at once. First, it tells the debtor that you are serious — that this is no longer an informal request between two people who know each other, but a formal legal demand with a named consequence. Second, it establishes a paper trail of your attempts to resolve the matter before litigation — courts look favourably on creditors who demonstrate reasonable effort before filing. Third, and most importantly, it gives the debtor a deadline — 7 to 14 days is standard — after which your next communication is a court filing.

What the Demand Letter Must Say

• ›The precise amount owed, broken down by invoice or obligation — not a round number, but the exact figure you will claim in court.
• ›The legal basis for the claim — goods supplied, services rendered, loan, rent arrears, deposit not returned — citing the relevant contractual document, delivery note, M-Pesa receipt, or bank transfer.
• ›A clear, hard deadline — ‘on or before [specific date], being 14 days from the date of this letter’ — not ‘as soon as possible.’
• ›The specific legal consequence of non-compliance — that you will file proceedings in the appropriate court and seek judgment for the debt, plus interest and costs.
• ›An invitation to respond in writing — this creates an opportunity for the debtor to admit the debt, propose a payment plan, or raise a specific defence.

If the Letter Fails: The Small Claims Court Process

If 14 days pass without payment or a serious response, you file. The Small Claims Court requires a Statement of Claim, your supporting evidence — contracts, invoices, delivery notes, M-Pesa or bank transfer records, WhatsApp messages that acknowledge the debt — and the KES 1,000 filing fee.

After the Judgment: Enforcement — The Part Nobody Warns You About

You have a judgment in your favour. The Adjudicator has confirmed the debt. The debtor owes you the money, and the court has said so in writing. Then nothing happens.

This is normal. And it is why enforcement strategy matters as much as the claim itself. A judgment without an enforcement plan is a document — an important document, legally significant, but not yet money in your account.

• ›GARNISHEE ORDER — If you know where the debtor banks, or who owes the debtor money, a garnishee order intercepts those funds and redirects them to you. A garnishee order against a bank account is one of the fastest ways to turn a judgment into actual payment.
• ›ATTACHMENT OF MOVABLE PROPERTY — A warrant issued by the court authorises a court bailiff to seize and sell the debtor’s assets — stock, equipment, vehicles — in satisfaction of the judgment.

The Six-Year Deadline You Cannot Afford to Miss

Under the Limitation of Actions Act (Cap. 22), a contractual debt claim must be brought within six years of the date the debt became due. Wait longer than six years, and you may lose your legal right to enforce it — permanently.

Six years sounds generous. But it goes quickly, particularly where debts are disputed informally for months or years before a creditor decides to act. If you are owed money and you have been waiting — stop waiting. The clock has been running since the day they should have paid.
