Interpleader is civil procedure that allows a plaintiff or a defendant to initiate a lawsuit in order to compel two or more other parties to litigate a dispute. An interpleader action originates when the plaintiff holds property on behalf of another, but does not know to whom the property should be transferred. It is often used to resolve disputes arising under insurance contracts.
In an interpleader action, the party initiating the litigation, normally the plaintiff, is termed the stakeholder. The money or other property in controversy is called the res. All defendants having a possible interest in the subject matter of the case are called claimants. In some jurisdictions, the plaintiff is referred to as the plaintiff-in-interpleader and each claimant a claimant-in-interpleader.
An interpleader proceeding has two stages. The first stage determines if the stakeholder is entitled to an interpleader and if he should be discharged from liability. The second stage is like an action at law to determine which of the claimants is entitled to the res.
For example, suppose a person dies with a life insurance policy. However, the insurance company knows there will be a dispute over who should receive the proceeds. The insurance company can file an interpleader action. The insurance company is the stakeholder, the claimants are the persons who might be beneficiaries under the policy, and the cash value of the policy benefit is the res. Under the proceeding as originally developed, the stakeholder would deposit the res with the court, and then the defendants would have their claims adjudicated by the court. Statutory modifications to the procedure, which vary by jurisdiction, sometimes allow the stakeholder to retain the res pending final disposition of the case. Typically, once the stakeholder deposits the res into the court (for example, the face value of the insurance policy), the stakeholder is released from the action and the claimants proceed against each other to determine which of them is legally entitled to the res. A disinterested stakeholder is entitled to costs including attorney's fees. Except for the denominations of the parties, the action proceeds for the most part as other civil lawsuits in the same jurisdiction.
