How many states in the US are 'No-fault' states?

Twelve states and Puerto Rico have no-fault auto insurance laws. Florida, Michigan, New Jersey, New York and Pennsylvania have verbal thresholds. The other seven states Hawaii, Kansas, Kentucky, Massachusetts, Minnesota, North Dakota and Utah use a monetary threshold. Three states have a "choice" no-fault law. In New Jersey, Pennsylvania and Kentucky, motorists may reject the lawsuit threshold and retain the right to sue for any auto-related injury. Colorado's law reverted back to the tort liability system in July 2003.

New York State also introduced the no-fault law for divorce cases in 2010 which allowed couples to part ways without assigning blame for the collapse of their marriage. A huge ease to the financial burden that can be associated with a divorce.
