When you agree to a settlement, whether you’re handling the claim on your own or working with an attorney, part of the process includes signing a release. This form basically says that you’re releasing the defendant from any future claims related to this accident.
The problem is that when you do this without a lawyer, you have no way of knowing if you really got all of the money you deserve. You had no one looking out for your best interests, so you don’t know if you’re likely to face future problems because of your injuries. You might not understand exactly what you’re giving up when you sign a release and cash your check, because you don’t have someone who understands the process to explain it to you.
