What occurs if a subpoena is not served within the required time frame?

If a subpoena is not served within the required time frame, it becomes invalid. This is because subpoenas are time-sensitive legal documents that require prompt compliance to ensure the intended parties are properly notified and can respond accordingly. When the time frame specified for service passes, any attempts to enforce the subpoena would be legally untenable, as the underlying purpose — which is to compel attendance or the production of documents at a specified time — cannot be fulfilled.

Thus, serving a subpoena outside the stipulated timeframe renders it ineffective, meaning that the recipient is not legally bound to comply with it. This highlights the importance of adhering to deadlines in legal processes, ensuring that all parties involved have a fair opportunity to respond and prepare.
