Article 14 Persons under a disability
In this rule, “person under a disability” means a minor or a patient for whom no receiver has been appointed.
A person under a disability shall not make an application in proceedings relating to another person except by his next friend and shall not resist an application in any such proceedings except by his guardian ad litem.
Where a person is to be appointed next friend or guardian ad litem of a person under a disability in substitution for the person previously acting as next friend or guardian ad litem, the appointment shall be made by the court but, except for this, an order of the court appointing a next friend or guardian ad litem of a person under a disability shall not be necessary.
Before the name of any person is used in any proceedings as next friend or guardian ad litem of a person under a disability there shall be filed—
a written consent of the first-mentioned person to act as next friend or (as the case may be) guardian ad litem of the person under a disability in the proceedings, and
a certificate by the solicitor acting for the person under a disability certifying—
that he knows or believes that the person to whom the certificate relates is a minor or patient giving (in the case of a patient) the grounds of his knowledge or belief, and
except where the person named in the certificate is the Official Solicitor, that the person so named has no interest in the proceedings adverse to that of the person under a disability.
