If it is a genuine offer and you could live with it, the (relatively) quick clean ending is possibly worth it. You only live once and the thought of wasting a year or two fighting out a divorce sounds unwise, when you could be getting on with your life.

Getting a lawyer to fight for every cent might cost more in fees and inflict months or years of stress and worry.

I'd get a lawyer to look over the settlement first to make sure there aren't any sneaky loopholes like shared debts and stuff, and to make sure it is honoured afterwards, but if it is something you could live with, maybe you should take it.
