Your best bet is to contact a personal injury attorney. There are a lot of moving parts here. Venue should be explored on the driver and the companies contacts in the United States. Worst case scenario you have to go to Canada. Either way these cases are heavily defended, you are way behind already.
Typically, auto insurance should cover this type of damage. Whether its the car owner that caused the damage or the auto insurance of the owner of the car that was damaged. As a practical matter you should contact your insurance carrier and make them aware of the situation and get their advice.
You can hire an attorney and file suit against them immediately or let you auto insurance take care of the claim thru your collision or Uninsured Motorist coverage. The insurance company for the guy who hit you might be looking for way to not allow coverage because they are not cooperating.
Your carrier can pay your claim then they can decide to go after his insurance for reimbursement, but at that point you will be out of the process other than to cooperate with your own insurance...
Yes you can, however, your insurance company may look to the other drivers insurance company for payment. This is not unusual. However, if the other company is at fault you should consider going after the property damage and the injuries from the other driver who was at fault. Also, if you decide to claim the property damage on your insurance you may want to talk to your agent and try to determine if it is going to affect your coverage in the long term by filing a claim. As always you can...
Yes you are entitled to damages for loss of earning if you can prove them. You will most likely have to show how many jobs you lost or a history of earnings so that they can calculated forward to get an idea of how you can claim. As usual if you have any questions you should consult with an attorney
If you have reached an agreement and you have an attorney then you have that attorney negotiate the debt on behalf of you. They usually will want some amount of payment. If you do not have an attorney then you should consult with one prior to signing any releases or settlement documents.
You can contact the court and ask them for the options that they may have. For example, a Driver's Safety Course, a trial, etc.
Or you can contact a traffic defense attorney who can appear in the court and defend you against the accusation.
You may have a falling product case. However, pursuing a claim against Walmart is very difficult and can be very expensive. There are law-firms who specialize in suing just Wal-mart. I suggest you contact a personal attorney with experience going after Walmart. And you should do so sooner rather than later.
It may or may not speed up the process, every insurance company has their own way of handling claims, as does every adjuster with these insurance companies. I suggest you contact an attorney who can review your claim and provide advice on how to proceed. Remember insurance companies are out to make money not to be your friend.
