I do have first hand experience of this - My Thai wife wanted to move jobs, from village to city, and she told me, after she had put in the request and spoke to other teachers from one of the most popular schools in the area, it would cost 'around 100,000 THB, maybe more'.
I, being the usual fine, upstanding morally-incorruptible (ha!) westerner, said 'Right, I want the guy's name, rank and school, and I will write to MOE and report him...'
Of course I did no such thing, just as well for my future here. She got a job at a less prestigious inner-city school, and paid nothing.

The points made previously about the whistle-blowers being more heavily fined than the wrong-doers is sad and worrying for the future of this country.

Sorry to reopen this -  after I had already thanked everyone - but I think there was an added stitch-up attempted here. The brother/owner was trying to get me to pay all taxes, which I almost agreed to, thinking it would only be the 2% transfer fee. There is, of course Specific Business Tax (SBT), stamp duty and Withholding Tax(WHT).
I am understanding WHT correctly? As far as I understand from other websites, if the seller is a company the WHT is 1% of the price, but if the seller is an individual, the WHT is based on their tax rate (he is a doctor, so could be on top tax rate).
Can this be correct, the WHT could be based on a 30% tax rate!!?? Surely I've misunderstood this?

It felt like we were being stitched-up, but no harm done, no money changed hands.
We're walking away from this one.
Thanks for your comments.

Thanks for the replies.
Mr Mario - I hadn't even heard of the immigration hot line! I don't want to annoy them, as Gudtymchuk said, most dealings with them are positive.
After I calmed down I checked on getting a UK marriage visa on the Hull Consulate web page - a very simple process compared with it's Thai equivalent.
No danger of reaching the 800K balance Thaiphoon - exchange rates have not been kind and I transferred the minimum to get me over 400K this time.
I have to see immigration again soon to get the 60 day 'supporting wife' extension - hopefully the answer will be 'no problem' this time.
