The time period for a caveat petition varies depending on the specific circumstances and the court where it is filed. In general, a caveat petition typically remains in effect for a period of 90 days from the date of filing. During this time, if any related legal proceedings are initiated, the caveator (the party who filed the caveat) is given notice and an opportunity to present their case before any orders or judgments are passed. It is important to note that the exact time period and any subsequent extensions can be subject to the rules and discretion of the court.
