Every action shall be prosecuted in the name of the real party in interest, except that an executor, administrator, personal representative, guardian, bailee, trustee of an express trust, person with whom or in whose name a contract has been made for the benefit of another, receiver, trustee of a bankrupt, assignee for the benefit of creditors, or a person authorized by statute or rule may bring an action without joining the persons for whom the action is brought. When a statute so provides, an action for the use or benefit of another shall be brought in the name of the State of Maryland. No action shall be dismissed on the ground that it is not prosecuted in the name of the real party in interest until a reasonable time has been allowed after objection for joinder or substitution of the real party in interest. The joinder or substitution shall have the same effect as if the action had been commenced in the name of the real party in interest.

Plain-English Summary
A District Court case belongs to the person who owns the right being enforced. Rule 3-201 makes that the default: the plaintiff named on the complaint has to be the real party in interest, not a stand-in with no stake in the outcome. That protects a defendant from a second suit over the same claim brought later by someone with a genuine interest in it, and it keeps the judgment binding on the person who controls the right.
The rule then lists who may sue without joining the person they represent: an executor, administrator, or personal representative of an estate; a guardian; a bailee; a trustee of an express trust; someone who contracted for another's benefit; a receiver; a bankruptcy trustee; an assignee for the benefit of creditors; or anyone else a statute or rule authorizes to sue in that capacity. When a statute directs that a claim be pursued for the use or benefit of another, the case is filed in the name of the State of Maryland.
Filing in the wrong name doesn't end the case. A court cannot dismiss an action for failing to name the real party in interest until it has allowed a reasonable time, after objection, for the real party to be joined or substituted. Once that happens, the case proceeds as if it had been filed correctly from the start.
Frequently Asked Questions
What does "real party in interest" mean in District Court?
It means the person or entity that holds the legal right the case is trying to enforce. Rule 3-201 requires that person's name on the complaint, subject to the fiduciary exceptions the rule lists.
Can a District Court case be dismissed just because it was filed in the wrong person's name?
Not right away. The court must first allow a reasonable time, after the defect is raised by objection, for the real party in interest to be joined or substituted into the case.
Who can sue without joining the person they represent?
Executors, administrators, personal representatives, guardians, bailees, trustees of express trusts, people who contracted for another's benefit, receivers, bankruptcy trustees, assignees for the benefit of creditors, and anyone else a statute or rule authorizes to sue in a representative capacity.
What happens if the real party in interest is joined or substituted in later?
The joinder or substitution has the same effect as if the case had been filed in the real party's name from the beginning.
Why would a District Court case be filed in the name of the State of Maryland?
When a statute directs that a claim be pursued for the use or benefit of another person, Rule 3-201 requires the action to be brought in the State's name.
