*Note that lawyers do not practice law (i.e. accept pressure by the opposite parties) for free; their personal advocacy is paid, so when asking a lawyer for their legal opinion 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 like when you visit a doctor and pay for their competent diagnose and accurate medical treatment.
