Kerri - You have to be commercial and now prioritise for your family. If you have to find a six-month rental deposit, and the only way of doing this is not to pay your mortgage, then so be it.
Once you have missed more than three mortgage payments on the property, the mortgage company have the right to proceed with possession proceedings.
Have you thought about exploring mortgage opportunities for when you are both discharged from bankruptcy? It may be possible to do a deal with the OR to buy out your own equity after the first year, on the basis that the costs of possession would outweigh any benefit. I am sure that you would be able to get a 90% loan to value mortgage after bankruptcy - Welshboy can confirm this if he is around - and this would avoid you having to move. You would, of course, have to fund higher mortgage payments, and thus compare this to the amount you would be paying to rent.
