This is awful. Was the wrong bim number part of the fraud or a mistake and is there a reason the original owner would personally point it out?
It could be either Ian, I think this happens more frequently than anybody realises & often isn't picked-up until the property is put up for sale or, because there are also other problems (as in my case) looked at far more closely, it took me 6 years to find out they had switched the numbers of the apartment around. The apartment I chose, was given the keys for, furnished etc etc, I eventually learned wasn't 'on the deeds' that one at all!. That also 'masked' the fact that Debts had also been taken out against mine

The only saving grace for me was Not signing for the Tapu, as I would have inadvertently also accepted the extra debt as well - Lucky escape eh!!!!!!
Even the MP they applied for was fraudulent! The ex-landowner had already transferred 'my' Tapu into another's name when he signed the paper-work applying for my MP, declaring he was still the Legal Owner (one of my ex-lawyers - didn't notice this!)....... I have the original paper-work to prove this, just couldn't find any Honest Legal body to help me prove it

You really do need eyes in the back of your head if you're unfortunate enough to deal with one of the many rogues about! My advice Re: POA's - Don't give yours to anyone (lawyers, agents etc. etc) that you wouldn't trust with all your bank account details including your pin number

The only lawyer I've haven't heard (or experienced) anything bad about is: Sule Beder.
