Whoa. Slow down. Litigation is a forcible action, and it's much too early to go there.
First, call the Red Cross. They will help you get stuff to make it for the time being. Next, contact the contractor company's office and ask if they are planning to send out an adjuster or if you should just submit a list of your property you lost and a claim for damages.
Also, get the apartment manager to commit to which apartment you will have, and when that apartment will be ready to move into.
You'll make a lot more progress by working with these other people to solve the problem than you will by trying to sue them from the get-go.
By the way, buy a renter's policy next time. It's not expensive, and would solve all of your problems right now instead of the days of stuff you have to do on your own.
Criminal law relates to violations of criminal statutes--i.e., crimes. It relates to those statutes dealing with crimes against the public and members of the public, with penalties and all the procedures connected with charging, trying, sentencing and imprisoning defendants convicted of crimes.
Civil law is that part of the law that encompasses business, contracts, estates, domestic (family) relations, accidents, negligence and everything related to legal issues, statutes and lawsuits, that is not criminal law. In a few areas civil and criminal law may overlap or coincide. For example, a person may be liable under a civil lawsuit for negligently killing a pedestrian with his auto by running over the person and be charged with the crime of vehicular homicide due to his/her reckless driving. Assault may bring about arrest by the police under criminal law and a lawsuit by the party attacked under civil law. 2) referring to one's basic rights guaranteed under the Constitution (and the interpretations and statutes intended to implement the enforcement of those rights) such as voting, equitable taxation, freedom of speech, press, religion and assembly. Generally these are referred to as "civil rights," which have required constant diligence and struggle to ensure and expand, as in the Civil Rights movement between 1950 and 1980. Violation of one's civil rights may be a crime under federal and/or state statutes. Civil rights include civil liberties. Civil liberties emphasize protection from infringement upon basic freedoms, while statutory rights are based on laws passed by Congress or state legislatures.
