Time limits to sue
You should know that, in many cases, you cannot sue after a certain period of time has gone by (the limitation period). The time limit depends on the reason for suing.
For general debt problems, such as contracts, loans, damage deposits and rent you must sue within two years from the time the debt began. An exception to this rule exists: if it has been stated in writing that the person knows the money is still owed, or if the person has paid part of the debt, the two-year limit starts when the debt was last acknowledged.
If you are suing for injuries or damages caused to yourself or your property (for example, assault, car accident, etc.), you must sue within two years of the injury or damages. If you wish to sue your own insurance company for failure to pay you as a result of an accident, you must do so within one year.
