Tennessee law requires that a personal injury lawsuit be filed within one year of the date causing an accident. Failure to file a lawsuit on time against the person or company responsible for your injuries will result in a loss of your rights.
There are certain exceptions to the one year deadline for filing personal injury lawsuits, but you should not assume that any exception applies to you unless a competent lawyer familiar with all of the facts advises you that you have more than one year to file a lawsuit.
Do not wait until the last few days before the one-year deadline to file a lawsuit expires to hire a lawyer. Delay in seeking a lawyer means that valuable evidence may be lost and it is likely that mistakes have been made that effect the value of the case.
