I have been charged with fraud for receiving unemployment benefits while working temporary. I paid back the amount. Defenses?

You should hire an attorney or get one appointed by the court if you cannot afford one. There may be substantive defenses to the crime, but that would require an attorney research the elements of the crime you are charged with and learn the specifics of your case. All that being said, your actions (i.e. paying back the money) should go a long ways towards getting you a very favorable plea bargain if you decide to go that route.

I am curious as to how and to whom did you pay the amount back two years ago? Was the pay back administered by the Arizona Attorney Generals Office? Do you have any proof that you paid the amount back?

You definitely should consult with a knowledgable Arizona-licensed attorney. Please let me know if I can assist you.
