It varies widely from case to case. Some cases, usually those in which liability is straightforward, may settle in a few months. Complex cases with disputes about who is responsible and what the damages are may take a few years. Often, being represented by an experienced litigation attorney can help your case to settle sooner. The attorneys on the other side know that your attorney is willing to take your case to trial and has the skill to win, so they are more likely to make a fair settlement offer.
