Lawsuits are tricky. They must be filed within a certain deadline, known as "statutes of limitation." If a person misses the statute of limitation without a very, very good reason, that person cannot file the lawsuit. Statutes of limitations are very important. A suit based on personal injury must be filed within two years of the act complained of. If a person is in a car wreck, that person must file a lawsuit within two years of the car wreck.
If the last day of the two year period falls on a weekend or a holiday, then the statute of limitations period is extended until the next business day. A lawsuit based on the state statute which prohibits discrimination must be filed within two years. This statute is known as the Texas Commission on Human Rights Act.
A suit based on defamation, libel or slander must be filed within one year of the act complained about. A suit based on breach of an oral contract must be filed within two years of the alleged breach. Suit on a written contract must be filed within four years of the alleged breach.
Of course, there are many exceptions to these statutes of limitation. If you have questions, you should speak with a qualified lawyer.
