Hello. The plaintiff, who filed a civil suit against his neighbor is dead. The motive of the suit is to stop the plaintiff's neighbor from constructing/raising the height of his compund wall which would deprive the plaintiff's house of light and air. After the death of the plaintiff, his house is now settled to Mr. AAAAA, third son of the plaintiff. For the suit to proceed is it sufficient if Mr. AAAAA alone signs the legal document (I dont remember what that document is called) which makes him eligible to represent the estate (plaintiff's house) and fight the suit in court or is it necessary that all the sons and daughters of the plaintiff sign a legal document to represent the plaintiff for this suit to proceed in court?
Thanks for your guidance.
