1) In terms of compesation, if he pays everything he took, you will be made whole. You should, to make things easier for you, try to get him to sign a settlement agreement in which you will give up any claims against him arising out of this incident if he pays you however much is left, within a defined time frame--the reason you want to do this is that while you can simply sue him for stealing from you (which is what he did), a suit for theft or professional malpractice is more complicated than a lawsuit for violating a settlement agreement, which would be a simple breach of contract case.1a) However, as stated, you have the right to sue him for theft and/or professional malpractice, so if you can't enter into an acceptable arrangment or he generally stops paying, you can file a lawsuit on that basis.2) What he did would be a crime, if done deliberately (rather than through some kind of careless/oversight/error)--you could report this to the police. That will not necessarily help you get your money back, but may provide a sense of justice.3) You could also report him to the accounting licensing board in your state.
