How much money should I ask for on a slip case?

If you have completed your medical treatment and have been released by the doctor or have been declared by the doctor to be permanent and stationary which means having reached a point in your medical treatment where no further improvement is anticipated, obtain your medical bills, medical reports and documentation of any wage loss.  Your personal injury claim filed with the store's insurance carrier should include these items.  Compensation for the medical bills is straight reimbursement.  Compensation for wage loss is straight reimbursement.  The medical reports will document the nature and extent of your injury and will be used to determine compensation for pain and suffering which is an amount in addition to the medical bills.  I would ask for quadruple the medical bills to compensate for pain and suffering, but not expecting to get  that.  That would be a starting point in negotiations.  If you are having residual complaints of pain or other problems from the injury, you might want to ask for more than quadruple the medical bills.  If the medical reports state that you will need future treatment, the estimated cost of that future treatment discounted to present value should be included.  If you ask for quadruple the medical bills to compensate for pain and suffering, the store's insurance carrier will respond with a much lower offer.  You can continue negotiations to try to get the insurance company to increase its settlement offer.  If the case is settled with the insurance company, NO lawsuit is filed.  If you are dissatisfied with settlement offers from the insurance company, reject the settlement offers and file your lawsuit for negligence against the store.  If the case is NOT settled with the store's insurance carrier, you will need to file your lawsuit for negligence against the store prior to the expiration of the applicable statute of limitations or you will lose your rights forever in the matter.
