Definition

Meaning

The procedural mechanism in law to bring a third party into an existing lawsuit, making them potentially liable to the defendant.

In legal contexts, it refers specifically to the action of a defendant who brings in a new party (the third-party defendant) who may be wholly or partially liable for the plaintiff's claim against the original defendant.

Linguistics

Watch out

Common Pitfalls

Translation Traps (for Russian speakers)

  • Not simply 'привлечение' (general attraction/involvement).
  • Specifically 'привлечение третьего лица (к делу) в качестве ответчика по встречному иску' or 'право на привлечение третьего лица'.

Common Mistakes

  • Using 'impleader' to mean a person (it's the action/mechanism). The person is the 'third-party defendant'.
  • Confusing it with 'interpleader' (a different procedure where a stakeholder forces multiple claimants to litigate among themselves).
  • Attempting to use it in non-legal contexts.
