In Arizona there is no such formal terminology. At our office, however, we use this term to mean a divorce in which there are no issues in dispute at all stages of the case. If you have such a case, we charge a very low, flat rate. You will know exactly how much your case will cost, because we know there will be no negotiations or arguments in court or out of court. Thus, we can offer a relatively low flat fee. Most divorce attorneys in Arizona do not offer flat fees for contested cases, because it is hard to know in advance how much time and effort each issue will take to resolve.
