I know you are in Scotland post-repossession, but was the property concerned also in Scotland?(posted 7491 days ago)I am not an expert on the differences in Scottish law but I do know that if the property concerned was in the England part of the UK as opposed to Scottish, then the debt will be governed by English law, not Scottish.
My advice would be to remain as you are - don't respond to anything and certainly after the date I gave earlier, you will be in the clear. In the meantime, do not worry about something that might not happen - see if it happens, if it does, deal with it then, not now!
Old saying "If you have nowt, they can't take owt" So even if they do catch up with you, if you have no other income apart from DSS/DWP benefits and don't own your own house in other words you are the proverbial "man of straw" then they will quickly realise you are not worth pursuing. It's when you have property or a decent income that they consider clobbering you!!!!
