If you get in a legal dispute, the hardest thing to do is wait. You want the situation resolved immediately, and it is understandable why. Litigation is very stressful. That being said, the best thing for your case is often the elapse of time. It takes time for the truth to work itself out.
For example, let's say you file a lawsuit. The defendant answers your complaint with a version of events inapposite with yours. This is standard, but it stresses you out. Through discovery requests, depositions and nonlegal factors like the defendant's economic situation, the truth will come out. It just takes time.
Where a lawsuit involves preliminary injunctive relief, or in a business dispute with multiple and varied economic considerations, a "rocket docket"may be preferable. Otherwise, time is usually your friend.
