If you rent from a foreigner,his/her passport number should be in the contract. No blue house book info is needed in the contract. If the owner/landlord is a Thai,then you need info from the ID.Still,no blue house book needs to be mentioned in the contract. But you need a signed copy of the Thai ID and the blue house book.
