How long do you have to file a medical malpractice case in Wisconsin?

There is a 3 three year statute of limitations in Wisconsin for suing for medical malpractice from the date of the occurrence. There is a "discovery" exception, which requires the lawsuit to be filed within one year from discovering that there was malpractice if beyond the 3 year limitation, but in no case can it be more than 5 years from the initial treatment. Keep in mind any attempt to file a lawsuit beyond the three year ordinary statute of limitations will be met with a motion to dismiss by the defense attorneys for the doctor and their malpractice carrier. Even assuming there is a case, it could turn out that the case gets dismissed. I am sorry for what happened to your husband. If you feel strongly that something went wrong, you should obtain a complete copy of his medical file including those records from the nursing home and have them reviewed by a medical malpractice attorney. If the attorney thinks there is something there, they will hire an outside medical consultant to determine if you have a viable claim.
