Legal Definitions - necessary party

A necessary party in a lawsuit is an individual or entity whose legal interests are directly impacted by the outcome of the case. While it is generally preferable for such a party to be included in the lawsuit to ensure a complete and fair resolution for everyone involved, their absence does not automatically prevent the case from moving forward. If a necessary party cannot be joined—for instance, due to issues like jurisdiction or venue that make their inclusion impractical or legally impossible in that specific court—the court may still allow the lawsuit to proceed among the existing parties, potentially addressing the absent party's interests in a separate legal action if needed.

Here are some examples illustrating the concept of a necessary party:

• Example 1: Property Co-Ownership Dispute

  Imagine two siblings, Sarah and Tom, jointly own a rental property. Sarah sues a tenant for unpaid rent and damages to the property. While Tom, as a co-owner, has a direct interest in the property's condition and any recovered funds, he might be considered a necessary party. If Tom lives in a different country and joining him would create complex international jurisdictional issues that would prevent the court from hearing the case, the court might allow Sarah's lawsuit against the tenant to proceed without Tom. Sarah could pursue her share of the damages, and Tom could pursue his own claim separately if he wished.

  This illustrates a necessary party because Tom's ownership interest is directly affected by the lawsuit's outcome, but the case can still move forward without him if his inclusion is problematic.

• Example 2: Contract with a Third-Party Beneficiary

  Consider a scenario where a company, "TechSolutions," contracts with a city to develop a new public safety app. The contract specifies that a portion of the app's revenue will go to a local charity, "Community Aid," as a third-party beneficiary. If the city later sues TechSolutions for breach of contract, alleging the app was never delivered, Community Aid would be a necessary party. Its financial interest in the contract's performance is directly affected.

  However, if Community Aid is a non-profit organization that operates nationally and joining them in the specific state court where the city is suing TechSolutions would create venue issues (meaning that court is not the proper place to sue Community Aid), the court might allow the city's case against TechSolutions to proceed. Community Aid could then pursue its own claim against TechSolutions in a more appropriate venue if the city wins and TechSolutions still fails to pay.

  Here, Community Aid's financial stake makes it a necessary party, but the lawsuit between the city and TechSolutions can continue even if Community Aid cannot be joined in that specific action.

• Example 3: Shared Debt or Loan Guarantee

  Suppose two business partners, Lisa and Mark, jointly guarantee a business loan from a bank. The business defaults, and the bank sues Lisa to recover the outstanding loan amount. Mark, as a co-guarantor, is a necessary party because his financial obligation and potential liability are directly affected by the outcome of the lawsuit against Lisa. A judgment against Lisa could impact his own future liability or credit.

  However, if Mark has recently filed for bankruptcy, an "automatic stay" might prevent the bank from suing him directly at that moment. In such a situation, the court would likely allow the bank to proceed with its lawsuit against Lisa alone. Once Mark's bankruptcy proceedings are resolved, the bank could then pursue a separate action against him if necessary.

  This example shows Mark as a necessary party due to his shared liability, but the lawsuit can proceed against Lisa even if Mark cannot be joined immediately due to legal protections like bankruptcy.
