If you are the victim, a settlement agreement is all about the settlement amount. The reason a victim signs a release is for payment for the harm that was done to them. You want clarity on who you are releasing and the type of claims you are releasing if you want the opportunity to bring more claims in the future. The most common claim left open is property damage. Certainly, more detail in a settlement release in a car accident is better than less detail for the defendant. But, usually, the victims care little about whether the release is vague as to which accident we are talking about or the specific identity of all of the parties being released because you go into it assuming you are giving up all of your rights to further pursue a claim against the at-fault driver (and, maybe, anyone else related to the facts of that accident). (There are exceptions. What if the at-fault driver is your ex-husband. But in most cases, the victim has no interest in pursuing another claim against the defendant.)
