Most of us won't need a probate law specialist to settle our estates after we die, but you may if you own a great deal of property or have assets exceeding more than a few hundred thousand dollars. If this is the case, it's a good idea to confer with an attorney in order to make your will as simple and easy to execute as possible.
Even within a field as narrow as probate law, there are subspecialties that you should be aware of when searching for an attorney. If, for example, you're contesting a will, a probate attorney whose experience is in malfeasance claims against executors and administrators may not be your best choice.
