Hi Anthony - many thanks. You can check the register to confirm the details, which are in fact a charging order that has been protected on the register by the creditor in the form of a form K restriction -
Practice guide 76: charging orders - GOV.UK
You can search online to confirm the register information but please check for an email from me first
You need to discuss the issue/charge with your legal rep/conveyancer to understand what happens re the debt/order following the death of your late wife and/or how to then apply to cancel the restriction/sell as appropriate
