Smiley, I agree with Lexie that it would be worth at least finding out what you'd be giving up, as property settlements are sometimes more complex than we imagine. Just a scenario, not saying it applies to you, but if you were a stay at home Mum, and he was out developing his career and earning power, then future earning power would be taken into account.
I was going to settle for much less than I was entitled to until I saw a lawyer (compulsory in Australia so you understand what you are agreeing to); it turned out I was entitled to more. My ex had moved on to another woman, so I didn't have as much motivation to be generous to her.
