Examples and Case Studies

Real-Life Example

Imagine a situation where a homeowner, Jane, sues a contractor, John, for damages resulting from a faulty renovation. John believes that the damage was actually caused by the sub-contractor, Mike, who installed the plumbing. John, as the original defendant, brings Mike into the lawsuit as a third-party defendant, claiming that Mike is responsible for the issues Jane experienced.

Case Study: Smith v. ABC Construction

In the case of Smith v. ABC Construction, Smith sued ABC Construction for defects in the construction of his house. ABC Construction, the original defendant, filed a third-party complaint against XYZ Plumbing, alleging that the plumbing defects were caused by XYZ's negligent installation. XYZ Plumbing became the third-party defendant in the case, responsible for addressing the claims made by ABC Construction.
