A layperson may be able to find answers to simple questions in a law library, but researching a complex issue, or the law on an entire case, is best left to the expertise of a professional. Small claims are a special matter. Most small-claims courts do not allow attorney representation, and therefore parties must present their own cases. Some lawyers may give small amounts of information without charge. Information is different from advice.
Advice is legal information given to a person with a recommended course of action.
When an attorney gives legal advice, the attorney may be liable for malpractice if the advice is erroneous. Attorneys are hesitant to give legal advice, and expose themselves to liability, without charging a fee.
