This service is useful for a person who wants to obtain an official answer to a question, collect evidence for use in court or other proceedings, or move a dispute or misunderstanding with an authority into the formal domain (for example, when an official refuses your rights verbally for obviously contrived reasons).
A well-drafted request can often fully resolve the client's problem, as the relevant official or authority will reconsider the prospects of a legal dispute and typically does everything possible to ensure full realization of the person's rights.
