Once both sides settle, you likely will sign a written agreement. The document releases the defendant from all liability for the accident. When you sign the form, you accept the money as complete reimbursement for the wrongful death claim. You would be unable to sue the at-fault party for further damages of the same incident in the future. The document continues to apply even if you later discover your case is worth more. However, a couple of exceptions could apply to allow you to reopen your claim. The defendant and their insurance company must act in good faith. If you prove the other side behaved in a fraudulent or coercive way, you can continue your case. Another exception is if you discover multiple parties were responsible for a loved one’s death. Written agreements remove liability for one defendant. However, you could sue a different entity for compensation for the same accident. The exceptions rarely occur, but you should speak to your attorney if you feel one may apply to your settled claim.
