An example of a Pro Hac Vice situation is when a lawyer is representing someone on a Federal judgment won in California, and there is a need to register and enforce that judgment in Florida where the judgment debtor absconded to. The lawyer is admitted to the California Bar, however not the Florida Bar. If one was representing themselves on a judgment they own, they could do this (if they know how), and move a Federal or most any other judgment, to another state and enforce it, because they are representing themselves. An attorney representing someone else, must work with a local Florida lawyer and get Pro Hac Vice access to co-represent their client in Florida.
Why spend for two lawyers? The reason to have your current lawyer stay involved in a court action in another state, is that your current lawyer might have extensive knowledge of your case. It would probably take too long, and cost too much to have a new lawyer in another state get fully up to speed on your case. In such a situation, it can be cost effective to have your attorney work with a local attorney. Your current lawyer may not even have to travel. They can coordinate their Pro Hac Vice access to the court with the local attorney.
