Selling second hand bike in different province.

[mrjohn]

I have just sold an old motorbike. However it was registered in Songkhla and the guy I sold it to lives in Korat. 
He said all he needed was my signature and copy of passport to transfer the ownership. 
Yesterday, he called to say that I will need to go with him in person to the provincial head office (200km) round trip. 
An incredible waste of time for a second hand bike.
Has anybody encountered this and is there any way round it?

There is absolutely no reason  for you to go in person..however he will likely need a "power of attorney" form  "transfer form" and possibly

(some provinces require it) a  certificate of residence  from you.
