The assigned judge, on terms that are just, may shorten or extend the time within which any act is permitted or required to be done by a party. Unless otherwise ordered, any motion or application for an extension of time to perform an act required by these rules must be served and submitted in accordance with rule 3.501(17).
A stipulation for an extension of time for the filing and service of documents required by the rules in this chapter requires approval of the assigned judge.
Nothing in this rule extends the time within which a party must bring an action to trial under Code of Civil Procedure section 583.310.
