Not until consulting with a lawyer first! Most of the time, an insurance company won’t pay you without obtaining your signature on a release. But a signed release allows the insurance company to be free from the obligation to pay anything more on your claim. It also prevents you from bringing up a lawsuit in the future.
A solid legal team like the attorneys at Lachman & Gorton should be able to review a release and advise you whether you risk losing any rights by signing it.
