The area of finance revolves around money. The term covers a wide variety of sub-themes including personal finance, corporate finance, money matters relating to non-profits, personal and corporate taxation, and many others. Because money is always involved, disputes can come up between parties.
Courts can become involved. These disputes can be nerve-wracking and, in some cases, highly damaging to one or more of the parties. Sometimes a third-party professional is needed. This is where a good expert witness finance may be useful.
