20+ year marriage, separated for last 5 years and living in separate spaces that I mostly support. She moved out and I am in the marital house. The kids go back and forth between houses. All agreeable, no significant issues. It’s time to move forward with the paperwork of divorce and assets.

When considering the division of assets for the house, should I be contemplating a 50:50 split of equity at current market value? Even though I’ve been the sole supporter of the house for 5 yrs and it has raised in value considerable over that time?

Same question for retirement considering the long term separation and market valuations over the last 5 years. Thanks!
