You should never settle a New York personal injury case until you have let enough time go by so that you are fully aware of all your injuries, and the full extent of them. It is not uncommon for New York personal injury lawyers to wait a year or more before even making a settlement demand; they want to see where the injury “ends up” before they settle. Once you settle, you generally can’t go back for more money, so you have to be absolutely sure you know the full extent of your injuries before settling.
But let’s say you were not so prudent. Let’s say you got into a car accident and suffer an insignificant neck injury. Instead of hiring a lawyer, you settled your case on your own with the insurance carrier for the at-fault driver for a small amount of money. As part of the settlement, you signed a “release” that said you were releasing the at-fault driver, and his insurance carrier, from any and all liability for all injuries “known and unknown” that were caused by the car accident. After you sign, and after you get the settlement money, you start noticing pain in your lower back. The back pain gets worse and worse, and your doctor tells you it was probably caused by the car accident. The doctor is recommending surgery on your back.
You want to undo the settlement, because now you feel the small amount of settlement money is not nearly enough to compensate you for a severely injured back. You re-read the release you signed. It clearly says you release the at-fault driver and his insurance carrier from liability for ALL injuries KNOWN AND UNKNOWN that stem from the car accident.
