What this practically means
#Executive summary
#Key legal issues
#Proof of duress in contract
The plea of duress failed for want of evidence and the commitment letter of 18th April 2025 was upheld as a valid acknowledgment of debt
The Respondent alleged he signed the commitment letter under duress but led no evidence of steps taken after the fact to avoid the agreement. Relying on Ruto v Cherono on what constitutes proof of duress, the court found the plea unsubstantiated and treated the letter as binding on the Respondent.
Evidentiary sufficiency of bank statements for the bank charges claim
The Claimant failed to prove the claim for bank charges
The bank statements produced only showed repeated card purchases at Tosha Petroleum Bombolulu and other merchants and Bank to Card transfers for unidentified purposes. The statements did not demonstrate that the Respondent was liable to settle the bank charges, nor did the commitment letter show such liability.
Quantum of the outstanding loan balance
The court accounted for Kshs. 199,523/- as paid via MPESA, leaving a balance of Kshs. 414,992/-
The Respondent's MPESA transaction screenshots for the period 4th September 2025 to 25th February 2026 evidenced partial repayment. Of the Kshs. 614,515/- principal, the court was able to account for Kshs. 199,523/- as paid, leaving a balance of Kshs. 414,992/- which the Claimant proved on a balance of probabilities.
Legal principles established
