In Wisconsin, nursing homes are regulated by the State and Federal governments and are usually required to be notified if there is a death or serious injury. Complaints can also be filed by individuals, which will prompt an investigation. Depending upon whether the nursing home is affiliated with a health care facility or not, may determine the amount of damges which can potentially be recovered. Also, whether the deceased person is married or has minor children can be a factor in the amount of damages which can potentially be recovered. This sounds like the type of situation where it would be best to consult with an experienced attorney in order to discuss the facts in more detail. Be aware that in Wisconsin, there is normally a three year statute of limitations which requires that a settlement occur or a lawsuit be filed within three years from the date of the incident.
