So the banks still have all the power because they have the secured debt!!
So if I have this right you have to stop paying the mortgage and offer voluntary surrender and then wait and hope the banks issue a judgement against you- and THEN go to UK- not simple is it??!!
Actually is is very simple. You just have to go to the UK and let the UK insolvency system/administrator deal with the bank.
But taking the step of going to the UK is a very difficult decision for a lot of people.
