Advocacy – it means speaking to protect the legal and financial interests of other people by the job and basically describes part of the lawyer’s work. For example, the lawyer’s oral plea in court.

*Note that lawyers do not practice for free; their personal advocacy is paid, so when asking a 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.
