Why it Matters?

Identifying the correct plaintiff is a live issue more often than expected. Wrongful death and survival claims typically must be brought by an appointed personal representative rather than a family member, subrogated claims belong to the insurer as the real party in interest, and claims of minors require a guardian. A defect in the plaintiff's capacity is a threshold defense that operates independently of the merits.
