Thank you for your question

The house is part of the total assets for division regardless of the original agreement.
The Divorce Court has the power to distribute the equity in any way it considers fair should you not be able to negotiate an agreement between you
I hope that this is of assistance - please ask if you need further details
To an extent yes.
If there are assets that predate the marriage and which have always been kept separate AND there are sufficient other assets to meet the reasonable needs of the other spouse then they may be excluded.
You are most welcome I hope all goes well
