Bona fide lawyer – this term details a law practitioner, who is self-employed and licensed member of the National Bar of Lawyers. He can act in a courtroom for protecting clients. With their activities, independent lawyers perform protection of the legal rights of their clients. Either in court or before any third parties and organizations. There are certain legal actions, where a lawyer should participate (even if not obligatory). For example, for serving convictions to the accused or questioning them, for performing lawsuits, etc.
Synonyms are “barrister” and “attorney”.
*Note that bona fide lawyers do not practice law for free. They perform paid advocacy. So when asking a bona fide lawyer for their acceptance of service on a concrete legal issue, or to represent you in court hall, you should pay them for their opinion and legal advice/representation. It is the same as when you visit a doctor and pay for their competent diagnose and accurate medical treatment.
