Thanks for the reply - this all makes sense, though I might considering changing the way you message it a bit. If you pitch it as a tool to check whether what you've already agreed upon is fair, then you potentially cause conflict if your assessment says the agreement isn't fair. Rather, it might be better as a starting point - if you don't know how to divide your assets, this tool will tell you what the law would default to, and then you can adjust from there.

Just two cents from a random guy on the internet!
