In a decision that resonates with how Kenya actually conducts business, the High Court just made it clear on an often overlooked principle: a contract is about agreement, not paperwork, even if that agreement is made through WhatsApp messages, phone calls, or SMS.

At the center of Fredrick Ochiel v. Kennedy Okoth (Small Claims Appeal E002 of 2025, decided 19 January 2026) was a dispute over the leasing of an ultrasound machine informally done via mobile communication.

The parties never signed a formal written contract. Instead, they discussed terms over phone calls and WhatsApp, agreed on a daily leasing charge, and acted on those discussions: the machine was collected, used, and partially paid for.

When the lessor demanded full payment of the amount still owed and the return of the equipment, the defense argued that “there’s no contract; nothing was put in writing or signed.”

The High Court, however, saw it differently. Rather than focusing on the lack of a formal written contract, the court zeroed in on what actually happened, establishing that there was a clear offer, a clear acceptance, and both sides knew what they were getting into. Hence an agreement.

It also found that consideration had taken place, since money changed hands, and their actions showed they were on the same page. 

In this context, WhatsApp chats, texts, and phone calls all counted as solid proof of this agreement. Just because nothing was written down didn’t let anyone off the hook if all the other evidence showed they’d worked things out and followed through.

Beyond the immediate dispute, the ruling speaks to a bigger shift happening in how people in Kenya do business and connect with each other. It’s a sign of how life and business work in Kenya now.

People rely on WhatsApp and texts for everything: negotiating, confirming prices, and sorting out delivery. Forget the old days of meeting face-to-face or scribbling notes. Most deals live in chat histories.

With mobile money and digital records becoming the norm, platforms like M-Pesa, especially when people use them alongside digital chats, leave behind a detailed record of every transaction.

These digital footprints, with payment alerts, exact times, and message logs, actually give a clearer, more reliable picture of business deals than old-school paperwork ever did. This is what modern business looks like now.

Still, it’s not all formal. Most deals happen with a quick “sawa?”, “wacha nitakutumia,” or “ok, tukutane kesho.” These throwaway lines can be binding.

The court made it clear: if you act like you’ve got a deal, and the digital records back you up, the law will treat it as real, even if it happened on your phone.

That means that Kenyans who casually agree on terms over WhatsApp or text messages need to realize they can end up as evidence in court.

While written contracts will remain the gold standard for clarity and certainty, the case demonstrates that the absence of paper does not mean the absence of a binding agreement. Judges will increasingly prioritize substance over form, focusing on what actually got agreed to and how the involved parties acted.

The ruling also highlights potential risks. Quick messages, vague promises, and assumptions can bind you into commitments you didn’t mean to make. So, if you’re tapping out a deal on your phone, be clear. Choose your words carefully. Make sure everyone’s on the same page.

This case illustrates how technology and law are tangled together like never before and the courts are catching up. Chat histories, screenshots, and call logs can all be used as new evidence.

While the recognition of oral and implied contracts is not new, common law has long accepted agreements where offer, acceptance, and consideration can be proven.

What is new is the central role of digital communication in establishing these elements. Courts now see electronic messages as solid, sometimes decisive, evidence that a contract exists.

For anyone doing business in Kenya, or just making promises over the phone, think twice before you hit “send.” As this case proved, your phone is a record of what you’ve actually agreed to.
