There is no exact answer to this question unfortunately.  Once you file a lawsuit for a car accident or slip and fall case, there is a process that must be taken to get to the finish line.  There are complaints to be filed, discovery process, depositions, mediations and then a potential trial.  I like to tell people that the court process takes a while and to expect anywhere from one to two years on average to get through the process.  However, like anything that is an average and it could end up shorter or longer.
