How Long Do Depositions Last?

I am in a car wreck lawsuit.  Depositions are happening next week.  How long do depositions last?

It depends on many factors.  There is no time limit on depositions in state court in Tennessee.  

The length of a deposition depends on the complexity of the case, the complexity of the injuries, the medical history of the plaintiff, the personality of the examining lawyer and many other factors. 

For example, in a car wreck case involving two cars, broken bones, a plaintiff with a relatively clean medical and work history and a reasonable insurance company lawyer the deposition of the plaintiff will last 3 or 4 hours.

If the medical history of the plaintiff is complicated another hour or two can be readily added to the deposition.
