Medical malpractice lawsuits, and all personal injury claims in Kentucky, need to be filed within one year of the accident or error in question. This deadline is known as the statute of limitations. If you did not learn of your injuries until a later date, the clock will start from the date of your diagnosis. Keep in mind that Kentucky has a five-year statute of repose, which requires that any medical malpractice claim be filed within five years of the error occurring.
