I found a great answer to this question over at the Texas Injury Law Blog. Here it is:
If you have been injured in an accident, you may benefit greatly from the services of a personal injury lawyer. First and foremost, a personal injury lawyer can determine whether or not you have a case. Your attorney will be able to determine who was at fault for your accident and inform you of whether you have a strong basis for a personal injury lawsuit.
A personal injury attorney can help ensure that you do not lose your right to bring your claim by making sure you file your personal injury lawsuit before the statute of limitations has run. Your lawyer will be an expert on Texas’s personal injury law and can make certain that you do not lose your legal right to compensation because of a procedural error.
By hiring a personal injury attorney, you are also taking the first step towards receiving fair compensation for your injuries. If your accident was caused by someone else’s negligence, then you may be entitled to compensation for both your physical and emotional injuries.
You’re also ensuring that the person responsible for your accident is held accountable for their actions, which reduces the chances that someone else will be a victim of their negligence in the future.
