Describe the procedure for a civil law trial. What are the possibilities for the outcome of a case?

Answer:

A civil trial starts with the pleadings, where the plaintiff files their complaint with the court. The defendant can then answer the claim. This brings the trial to discovery, where each side gathers evidence for their argument before the judge. Once discovery is over, the sides will meet with the judge for the pre-trial conference, where the matter to be decided is discussed. The trial itself will follow, and then the judge will decide on the outcome. At any time, the judge may offer a summary judgment, which resolves the case by proclaiming no conflict of facts and deciding on the merits of the law, a default judgment if the defendant fails to respond to the summons, or a civil settlement, if both litigants decide to agree on a fair resolution.

Why would a good lawyer not tell a client how their case will come out at the initial consultation?

Answer:

A good lawyer knows that every case is different and without doing research. A good lawyer will not guarantee the outcome of any case. Someone who guarantees the outcome of a case at the outset is either mistaken or a liar.
