Which action does NOT extend the time for a party to respond to legal proceedings?

In legal proceedings, certain actions can impact the timeline for a party to respond, while others do not. Accepting service, waiving service, and making a voluntary appearance are all actions that signify acknowledgment of the legal proceedings and can often lead to extensions or implications on the timeline for response.

Failing to appear in court, however, does not extend the time for a party to respond; rather, it can lead to negative consequences for that party, such as a default judgment against them. If a party does not show up, the court may proceed without them, resulting in an automatic judgment based on the information provided by the appearing party. This action can be detrimental, as it does not afford additional time for the absent party to address the legal matter.

Thus, failing to appear in court clearly does not provide any extension for response and can actively harm the party's position in the proceedings.
