This is our plan, as well as any acquired assets communally during the marriage to be just that with the exception of the 401k vehicles. Just looking for what an equitable split might be before another property is acquired. Maybe percentage based?

This isn't the info that I asked for and I think that a real marriage means that you plan for all events while in love. Including the compromise of your marriage and assets when you aren't in love from the original intent of care that started your Union. Being smart about future contingencies is excellent personal finance.
