It would be advisable for your wife and daughter to be represented by a personal injury attorney.  They have separate personal injury claims.They can protect themselves if their injuries worsen by NOT attempting to settle their cases until they have completed their 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 their treatment where no further improvement is anticipated.  If they still have pain or other residual complaints after completing their medical treatment, that should be documented in the medical reports, and will result in compensation to include the estimated cost of future treatment.They should obtain their medical bills, medical reports and if applicable documentation of wage loss upon completion of medical treatment and release by the doctor or after being declared permanent and stationary.  Their claims filed with the at-fault party's insurance carrier should include those items.Compensation for the medical bills is straight reimbursement.  The medical reports will document the nature and extent of their injuries and will be used to determine compensation for pain and suffering which is an amount in addition to the medical bills.  Compensation for wage loss is straight reimbursement.  If their cases are settled with the at-fault party's insurance carrier, NO lawsuit is filed.If one or both are dissatisfied with settlement offers from the insurance company, reject the settlement offers and file a lawsuit for negligence against the at-fault party.  If your daughter is a minor, you or your wife will need to be appointed guardian ad litem to file a lawsuit on your daughter's behalf since a minor cannot file a lawsuit herself.If the cases are NOT settled with the at-fault party's insurance carrier, the lawsuit for negligence against the at-fault party must be filed prior to the expiration of the applicable statute of limitation or your wife and daughter will lose their rights forever in the matter.The property damage claim on your vehicle is separate from the personal injury claims.  You can probably settle the property damage claim yourself or you can have the attorney do it.
