Civil law is about cases where an individual, a company or even government does something wrong that causes you loss or injury for which you as a citizen can seek compensation. Sometimes a citizen may seek compensation on behalf of the community or public where they have a common interest. Examples of civil law include the law governing formation and putting into practice of contracts, the law of marriages and the law of succession, Land laws.
The purpose of the civil administration of justice is to determine the rights of those in a dispute who suffer from the wrong by providing compensation in form of damages, or having the action that is causing the wrong stopped (injunction), declaring for instance that land claimed by another person belongs to him or her. In some cases, it may be that a contract was not completed and needs to be completed.
