More often than would think, insurance companies seek to add terms to a Full and Final Release which they would not otherwise be able to get in Court.
A Full and Final Release is a legal document which gets signed when a case gets settled outside of Court.
This is standard. Anyone who settles their case outside of Court in a personal injury or long term disability action will be asked by a Defendant to sign such a Release.
Generally, the Release will contain provisions detailing the amount of the settlement, terms that the settlement is final and binding on both parties, that the Defendant is prepared to pay the settlement amount, but does not admit liability, that the Plaintiff cannot sue again over this specific cause of action and that should s/he do so, that the Release will be relied upon to dismiss the case with costs; and that the terms of the settlement are confidential, but can be disclosed to lawyers, accountants and financial planners.
These terms are expected to be contained in a Release by plaintiff side personal injury lawyers. But sometimes (more often than you would expect) sophisticated insurers and their insureds try to get terms into the Release which fall well outside of the scope of the litigation. The Defendant is trying to get through the backdoor, what they cannot get through the front door.
