Hi pat
This is an explanation I got elsewhere
"The bank can opt out of the bankruptcy process: i.e. it can still hold the mortgage. However, the borrower would have no more liability to the bank UNLESS he agreed to take on the liability post-bankruptcy.
EG, Market value of house €100,000. Mortgage €300,000.
The borrower might wish to keep the house , and negotiates with the bank that he will keep the house with a reduced mortgage of €200,000. i.e. the bank writes off €100,000."
So, in your case, you will have no more liability.
The bank can rely on their security and repossess the house, or if you and your wife continue to make payments, then they will probably not take any action.
When you emerge from bankruptcy after three years, you are free to walk away. Or you could ask the lender for a mortgage to buy the house from the Official Assignee.
