Asset protection requires expertise in many different areas of law.  One key area is litigation, since the ultimate test of any asset protection plan is how well it will hold up in court.  Asset protection attorneys must also have expertise in business entities (particularly limited liability companies); trusts; and estate planning (since asset protection planning should generally be integrated with your estate plan). 

Asset protection strategies can also have very significant tax consequences.  For example, moving assets in and out of business entities (or even between individuals) can potentially have both gift and income tax consequences.  Changing an S corporation into an LLC may result in a liquidation of the company for tax purposes.  Holding funds in offshore accounts will likely mean that you will need to file FBAR and FATCA reports.  And those are only a few of the many tax-related considerations that might have to be addressed with an asset protection plan.  So the law firm doing your asset protection planning should have expertise not only in litigation, business law, trusts and estates, but in tax matters as well.
