Statute of limitations refers to the need to file a lawsuit within a time limit. In Texas, many causes of action have a two-year statute of limitation, but not all. Some lawsuits, such as lawsuits against the government require a notice within a short time. The time begins to run when a cause of action accrues. A good example is someone negligently running into your car. The statute of limitation begins on the day of the accident. This issue can become more complicated. Sometimes, you have no way of knowing that you have a cause of action for years, such as discovering ill effects from taking a medication or being exposed to chemicals. It is important to seek the advice of an attorney and doctor if you suspect that you are having problems but don’t know for sure if it relates to the negligence of another or an unreasonably dangerous product.
