Every action shall be prosecuted in the name of the real party in interest, but a personal representative, guardian, curator, committee of a person of unsound mind, trustee of an express trust, a person with whom or in whose name a contract is made for the benefit of another, a county, municipal corporation, public board or other such body, a receiver appointed by a court, the assignee or trustee of a bankrupt, an assignee for the benefit of creditors, or a person expressly authorized by statute to do so, may bring an action without joining the party or parties for whose benefit it is prosecuted. Nothing herein, however, shall abrogate or take away an individual's right to sue.
