I didn't get the title quite right but we are looking to buy a house and around 12+ years ago my DH has a bank acc and credit card with a large well known bank. He at the time was homeless and didn't consider paying it back and the accounts were maxed out. He was about 18/19 at the time and it probably came to £1500 in total before charges. My question is if he was to attempt to open a help to buy isa with this bank would they pursue him for this money? I would fully accept the consequences in this but need to know to prepare for it as there is likely to be lots of charges added to that total
