Without seeing your paperwork and particularly what is on your receipt and assessing whether it is likely that it is bona-fide it is not possible to give any useful answer through AB. You should write to your local District Land Registry Office with your story, enclosing copies of all the paperwork upon which you intend to rely and asking whether it is sufficient for a formal application by you to be Registered as Sole Proprietor is likely to succeed. Be aware that the LR Registrar's are Senior Solicitors and can and do instigate criminal charges if they think that someone is trying it on.
