A Massachusetts Motion for Leave to File Third Party Complaint is a legal document that seeks permission from a court to add a third-party defendant to an existing lawsuit. This motion is typically filed by the original defendant in order to shift a portion of the liability onto another party who may be responsible for all or part of the plaintiff's claims. In Massachusetts, there are different types of Motions for Leave to File Third Party Complaint that can be asserted depending on the circumstances of the case. These include: 1. Imp leader Motion: This type of motion is commonly used when the defendant believes that a third party should be held accountable for all or part of the damages claimed by the plaintiff. The defendant seeks permission to bring the third party into the case as an additional defendant, enabling them to share in the liability. 2. Contribution/Indemnification Motion: In certain situations, the original defendant may believe that they are only partly responsible for the plaintiff's claims and that another party should share the responsibility. This motion requests the court's permission to add a third party who may be entirely liable or partially responsible for the damages. 3. Contractual Indemnity Motion: When a contract exists between the defendant and a third party, the defendant may file a motion seeking leave to bring that third party into the lawsuit based on a contractual indemnity provision. This motion asserts that the third party has an obligation, as outlined in the contract, to indemnify and defend the defendant against the claims made by the plaintiff. 4. Cross-Claim Motion: In some cases, a defendant may want to bring a claim against another defendant involved in the same lawsuit. This motion requests permission to assert a claim against the co-defendant based on their potential liability or if the co-defendant may be responsible for the plaintiff's damages. To file a Massachusetts Motion for Leave to File Third Party Complaint, the moving party must provide a detailed explanation of the relationship between the third party and the original defendant, the reasons for seeking the third party's involvement, and how their inclusion would impact the overall case. It is essential to include relevant keywords such as Massachusetts motion, leave to file, third party complaint, imp leader, contribution, indemnification, contractual indemnity, cross-claim, and court permission while drafting the motion.
