The bottom line

#

A Kenyan court said a person with dementia must first use the Mental Health Act process to appoint a supporter before asking a court for a next friend.

What this practically means

#

Executive summary

#
By notice of motion dated 9th December 2025, the plaintiff/applicant sought leave to amend his originating summons to bring in a next friend, James Oundo Okumu, to represent him on the ground that he suffers from dementia and other health challenges and can no longer prosecute his case. He relied on a medical letter from Mediva Wellness Center dated 12th February 2024 and supporting affidavits of his advocate and the intended next friend. The respondent opposed, contending the medical letter was outdated, that no recent psychiatric assessment or formal adjudication under the Mental Health Act existed, that the applicant had continued to instruct advocates and swear affidavits demonstrating capacity, and that the application was a late, prejudicial attempt to amend pleadings on the eve of hearing. The court identified a sole issue: whether the applicant had made out a case for the orders sought. On the next friend, the court accepted the medical evidence of dementia but held that the Mental Health Act provides a mechanism for appointment of a supporter (section 3I) which should be exhausted before recourse to court; it therefore declined to admit the next friend but left the applicant free to return once a supporter was appointed. On the amendment, the court found the respondent had not shown the amendments would introduce a new cause of action or incurable prejudice, and allowed the amendment as per the draft. The application partially succeeded; costs were put in the cause. Ruling delivered at Nyahururu on 6th July 2026 by L. N. Waithaka, Judge.

Key legal issues

01

Whether a next friend may be appointed for a litigant alleging mental incapacity

Holding

The court declined to appoint a next friend, holding that the Mental Health Act provides a mechanism for appointment of a supporter which should first be utilised; the applicant may return to court once a supporter is appointed.

Reasoning

The court accepted the medical report showing dementia but noted the Mental Health Act defines and provides rights for persons with mental illness, including the right to appoint a supporter under section 3I, exercisable by the person or his representative. Since that statutory mechanism adequately addresses the issue, the court held it should be exhausted before recourse to court. It declined to appoint a next friend but allowed the applicant to move the court afresh upon appointment of a supporter.

02

Whether leave to amend the originating summons should be granted

Holding

Leave to amend was granted; the respondent did not demonstrate that the amendments introduce a new cause of action or incurable prejudice.

Reasoning

The court considered the intended amendments and the grounds of opposition. It found the respondent had not shown the amendments would introduce a new cause of action or cause prejudice incapable of remedy by costs. Amendments are generally allowable in good faith and without prejudice; the court therefore allowed the amendments in the manner indicated in the draft amended originating summons.
