It is somewhat of a cliché to say "Every case is different," but it is true. The cost of a divorce varies depending on a number of complicating factors, including the number of issues involved, the degree of civility or hostility between the parties, the quality of each side's respective attorney, and whether experts are needed. Divorce attorneys are prohibited from being paid on a contingency basis, which means the attorney cannot be compensated based on the outcome of the case. As a result, most divorce attorneys bill for their time, regardless of the outcome. 

The cost of a divorce can be significantly increased if one side is unreasonable. This means that you can be very reasonable and set realistic expectations, but if your spouse is unreasonable or vindictive, the case may take longer and cost more to bring to resolution. A quality divorce attorney can move the case forward, but a quality attorney is going to charge more for their time than an ordinary or inexperienced attorney.
