Lawyers give people and companies advice and tell them what they can and can't do under the law. Sometimes, they hire lawyers to take their side in court against other people or companies, or against the government. Lawyers spend a lot of time doing research. To be a good lawyer, a person must be good at finding facts in books, on computers, and in other places. Lawyers also interview people to get information. After doing research, lawyers make arguments to show that the people they work for should win in court.
