Unfortunately, your daughter does not have any recourse after signing the release.  By signing the release, your daughter has released the other party from liability in return for the $1000 she received.  She will not be able to file a lawsuit because of the release.  The purpose of a release is to prevent one from suing again on the same claim.  The fact that the release was signed prior to filing a lawsuit will bar a future lawsuit in this matter.Auto accident injuries frequently appear a significant time after the accident.  If the release had not been signed, your daughter could have received additional medical treatment and when she completed her treatment and was released by the doctor, that would have been the appropriate time to pursue her personal injury claim against the other party's insurance carrier.  The claim would have included the medical bills, and medical reports which would have documented the nature and extent of the injury as a basis for compensation for pain and suffering.  In addition, any wage loss should have been included in the claim.  Compensation for the medical bills and wage loss would have been straight reimbursement.  Compensation for pain and suffering would have been an amount in addition to the medical bills.  At that point, if your daughter had been dissatisfied with settlement offers from the insurance carrier, she could have filed a lawsuit against the other driver.
