Angie, could you please be more specific? Did you only give a retainer to your attorney? If you went to court, I am most certain the retainer is possibly expended due to preparation time, telephone calls, service of process, etc.
Well, this depends on your lawyer's payment plan, but you don't always have to pay the entire amount if your wife doesn't get served. However, you might incur a number if court costs, like filing fees.
