Your lawyer cannot and will not make that decision for you. If a case is settled by agreement early on in the process you may never see the inside of the courthouse, however, there are still certain legal procedures that have to be followed to turn your agreement into a judgment and end your marriage. If you and your spouse cannot settle your case, it will go to trial. At trial you each tell your story to the judge. It is told through your testimony, the testimony of other witnesses, and documents called exhibits.
Trial is likely to be expensive and unpleasant.
However, it can be the only alternative to never-ending unreasonable settlement demands. Still, trials are risky. No lawyer can predict the outcome of a trial because every case is different. Sometimes, a trial does not end the case. Each party may, within a limited period of time, appeal to a higher court.
