Courts are responsible for various legal processes and decisions, as required by laws.
Some legal processes such as changing a name, are relatively straight forward and can be done without a lawyer. Other court procedures are complicated and require a lawyer.
Courts make decisions about crimes and disputes and what is done. They decide if a crime is committed and the punishment. They decide private disputes when people can’t resolve themselves.
Court cases end up in different types of courts depending on situations and laws. There are many types of courts.
The judicial branch (courts) operates separately from legislative and executive branches.
