Code of Civil Procedure Article 51

Any person who intends to conduct litigation against another person, but who is without the capacity to litigate and who does not have a statutory agent or whose statutory agent cannot exercise authority, may file a motion with the presiding judge to appoint a special representative for him/her when there exists a danger that delay will result in prejudice.When a person needs to initiate an action but is without the capacity to litigate and does not have a statutory agent, or where the statutory agent cannot exercise authority, the relatives of such person or anyone who has a legal interest in such action may move for the presiding judge to appoint a special representative.A ruling appointing a special representative shall be served upon the appointed special representative.Except for such acts of litigation as abandoning a claim, admitting a claim, voluntarily dismissing an action, or settling a case, a special representative is authorized to conduct all acts of litigation for the party represented until the party's statutory agent or the party himself/herself assumes the action. The expenses necessary for appointing a special representative and for the special representative to conduct acts of litigation may be ordered to be advanced by the movant.
