Some people who file a lawsuit dont have any clue and ideas what it takes to win their case. They just rely on their lawyer to do the job not knowing how to reduce the legal cost of the case. The common mistakes people make is that they hire a lawyer and hope for the best.
Some lawyers do not care of their clients interest. They tend to take care of their sole interest only. Too often people hire lawyers who are afraid to stand up to arrogant judges, too timid to press opponents for evidence, unwilling to fight tooth-and-nail for rights the lawyer promised to protect, or simply bailing out at the last moment, leaving their clients to fight their legal battles alone.
