Good pastoral support from forum members who perhaps are a little more expert in that field than myself.
From a technical insolvency point of view, you could argue that the previous remortgage has eroded your partner's share of the equity, and that she no longer has a share of the property. This would be acceptable in law, and then your partner could either declare herself bankrupt, or enter into an ongoing payment arrangement with her creditors. You may well feel that this is a better route than risking even more of your personal assets, and a formal insolvency would stop her being able to obtain credit in the future thus allowing a period of readjusment which could not be supported by ongoing borrowings.
A perhaps harsh view, but you also have to think of yourself.
