Hi cas and welcome to the forum. As ever we are glad to help with any type of query.
You will need to effect a Land Registry search to ascertain ownership of this portion of land. It is likely that it still forms part of the bankruptcy estate, unless it has been disclaimed by the Trustee.
If the Trustee has ceased to act, then the land may still be available for bankruptcy creditors, by being held as an "unrealised asset" by the Official Receiver. In which case you can make an offer to purchase it directly to said office.
Do you know the identify of the bankrupt, and what part of the country do you live in? I will try and find out which Official Receiver's office is likely to be dealing with this for you.
