How to sue
Free consultation. Most lawyers will talk to you over the phone to analyze the situation and tell you if you actually have a case or not. If you have a case they will tell you for absolutely no charge to you and they have no reason to lie because it's free money for them.
Small claims vs. Large claims. A small claim is when you are sueing someone for an amount not exceeding $5,000 USD. However, A large claim is when the amount is exceeding $5,000 dollars and no larger than $30,000 dollars.
Get medical records if applicable. If you have a personal injury case, you may want to go ahead and get your medical records related to the incident. You will also need to take pictures of your car if you've had an accident or any items related to the incident. This step isn't required but your attorney will likely ask you to do this if you want to speed up the process.
Get witnesses. Any time you sue someone over a financial dispute, the defense and plaintiff usually have witnesses that were present during the altercation or incident. Your witness can be a relative, friend or family member as long as they were present during the incident.
Hire specific attorneys. A lot of people will hire the wrong attorney by hiring a personal injury attorney for something that's not even related. The problem is, most attorneys won't turn down business even if they aren't the best man for the job. If you want your lawsuit to be successful, it's important that you research the specific attorneys related to your case.
Be aware of fake attorneys. You may not believe this, but their are attorneys that are able to practice law without a license because of the lenient background checks done by the courts. This is why it's important to check with the American Bar Association to find out if an attorney has even passed the bar. In larger cities, this isn't a problem but it can be a huge problem in small towns and many attorneys get away with this for years while charging clients the same price.
