Legal Question in Personal Injury in Wisconsin

In Wisconsin, for an adult, there is a three year statute of limitations to either settle an injury claim or commence a lawsuit against the responsible party and/or his/her insurance company. If your friend had auto insurance, you can see if he/she had medical expense coverage under the policy that might still be used to pay the bills, otherwise, if your friend was negligent in causing the accident, then your friend's liability coverage of his/her auto insurance policy would be responsible to pay for your medical expenses, lost wages and pain and suffering. I cannot tell from your post how the accident happened and if there was another vehicle involved, so there may be other insurance available on another vehicle. If your friend did not have auto insurance and if there was no other vehicle or other auto insurance available, you may also be able to make a claim for uninsured motorist coverage and medical expense coverage on vehicles that you owned or which others owned in your household. Lastly, you can certainly sue your friend in Small Claims Court for the maximum of $5000.00, without an attorney, or you can sue your friend in Large Claims Court for more than the $5000 maximum, if you claim is worth more, however, you will need an attorney to represent you. I would suggest that you consult with an attorney to discuss the issues in your case in more detail, to be able to give you a more complete answer than I can provide, given the limited information which you have provided.
