Kansas Statutes Chapter 59. Probate Code § 59-2205. Persons under disability

The petition of a person under legal disability shall be by his or her guardian, conservator or next friend. When it is by his or her next friend the court may substitute the guardian, conservator, or any person, for the next friend. The court may appoint a guardian ad litem in any probate proceeding to represent and defend a party thereto under legal disability. All possible unborn or unascertained beneficiaries may be represented by living competent members of the class to which they do or would belong, or by guardian ad litem, as the court deems best.
