Notice is also an important requirement in ending legal relationships. For example, a notice given either by the tenant to the landlord, or vice versa, indicating that either the tenant intends to surrender possession of the premises on a certain day or that the landlord intends to regain possession of the premises on a certain day. Many kinds of contractsrequire that similar notice be given to either renew or end the contractual relationship. before a lawsuit is started, a notice of claim must be filed within a reasonable time, usually one three to six months after the injury occurs. The notice must contain the date of injury, how it occurred, and other facts that establish that the prospective plaintiff has a viable Cause ofAction against the government.Failure to file a notice of claim within the prescribed time period prevents a plaintiff from filing a lawsuit unless exceptions to this requirement are provided by statute or ordinance.
