Only if the creditors saw fit to get what in the UK is called a charging order and then see fit to enforce that by order for sale.
The question, though, is how much is the debt, and how much is 14 Branchland Court worth? Remember that securing any judgements on it will be at the bottom of the heap for priority.

Or, they could just send in the bailiffs to repossess the horde. But how much would they get, at auction, for heaps of strangely malodorous Lego sets, furniture embedded with the stench of rotting fish heads and old and crispy sick, and Pokémon cards with a thin film of nameless dried grime all over them? Even Chris's car can't be worth all that much because it's aged and probably hasn't been properly maintained if at all.
