In Washington, there are two types of Motions for Leave to File Third Party Complaint that can be filed: 1. Imp leader Motion: This type of motion is typically filed by a defendant who believes that a third party shares responsibility or liability for the plaintiff's claims. The defendant seeks permission from the court to bring in the third party under the theory that they should be responsible for some or all of the damages claimed by the plaintiff. The imp leader motion allows the defendant to shift part of the liability to the third party. 2. Contribution/Indemnity Motion: In certain situations, a defendant may believe that while they may be partially responsible for the plaintiff's claims, another party should share in the obligation to compensate the plaintiff. This type of motion is often filed when the third party has a legal obligation or duty to indemnify the defendant for any damages awarded to the plaintiff. The defendant seeks permission from the court to include the third party to ensure that they contribute their fair share towards the plaintiff's claims. Both types of motions for leave to file a third-party complaint require the defendant to show good cause for bringing in the third party. The defendant must present a compelling argument demonstrating why the addition of another party is necessary for the fair resolution of the lawsuit and to prevent injustice. The court will review the motion and consider factors such as the timeliness of the request, whether the third party's involvement is relevant, and how the addition of the third party may affect the existing case. Once the motion for leave to file a third-party complaint is granted by the court, the defendant can proceed with serving the third-party defendant, who will then have the opportunity to respond to the claims made against them. The third-party defendant becomes actively involved in the lawsuit and has the right to present their defense and assert any counterclaims. In conclusion, a Washington Motion for Leave to File Third Party Complaint is a crucial legal tool for defendants in a lawsuit to add a third party who they believe shares responsibility or liability for the plaintiff's claims. By seeking permission from the court, the defendant can ensure that all parties involved in the dispute are properly included, allowing for a fair resolution of the case.
