Most people get involved in at least one lawsuit over the course of their lifetimes, and we often don't think of the needs for having someone to assist us in these cases until that need arises. Getting proper litigation help is a crucial step of correctly tackling a lawsuit, and it can make all the difference between a successful case and a failure. Those who expect lawsuits or frequently get involved in them normally have a personal attorney, though if you don't, the court will usually offer you a public one to represent your case.
It's very important to realize the difference between attorneys who work on all types of cases in general, and those who specialize in civil litigation - even though the first kind can help you get through a lawsuit in some cases, you have a far better chance of success if you hired someone who's actually well-familiar with the idea of representing people in civil cases. There are even entire law firms dedicated to providing civil litigation, though the availability of those depends on the circumstances.
You should also be wise about choosing your attorney - keep in mind that they'll be charging you by the hour, and some litigation cases can go on for prolonged periods of time. Thus, make sure you have a good idea of how much you're willing to pay for their services, and be sure to ask them what the probability of getting you through your case is - if it's high enough, it may be worth hiring them.
