What is required to file a motion for continuance?

There are unlimited reasons for filing a motion for continuance. Having to switch attorneys in the middle of a case is a good reason. As long as you can show the court that you are making every effort to find a new attorney as quickly as possible, they should grant the motion. The last thing the court wants is to force you to go to trial without counsel. Your attorney can file the motion in conjunction with a motion to withdraw, and probably get the other side to agree without having to appear before the court to argue the continuance.
