Actually, I think your advice is extremely poor and you are vulnerable to some substantial losses.
First, the car will be her's as it is paid off and in her name.
The house must of had a down payment I assume by you and with 11 years of payments and appreciation, how much equity is in it? Seperate property even purchased after marriage could in fact be argued by her attorney that the house is hers. The fact the mortgage is in her name is a huge mistake as, she is the mortgage holder and therefore can claim it is soley hers.
Additonally, there is alimony in Thailand if she desires to ask for it.
On the house, even if the court decides it is communal property at least half of the equity will go to her.
Hope you stay married, but if not it seems you have dug a hole for yourself if you divorce and your advice I think is terrible that I would recommend no one take.
