Do not marry - no children...True for the feminist region - laws are clearly against you as a man.
Is a foreign wife really better if you decide to move to her country? Maybe yes, but this does not say, the law of her own country is helpful to you as a foreign man if the Thai girl turns out to be crap and is cheating you.
Recently, Thailand is doing everything to please the world ....with 'Women Rights' and new laws. Be careful. Some foreign men were trusting too much and lost everything, no difference to the Western world.
How is this possible? Love makes you blind, but seriously said, yes, legally seen it's much better in Thailand than in the Western feminist region, why to marry anyway?
Let us check about the present Thai legal situation:
There is no law in Thailand, which requires a foreign man to marry...and there is no law in Thailand, which might be useful to you if you are married to a Thai national.
Basically the same, why to marry a Thai woman, for what reason?
As a foreign man, you are able to buy your own condominium in Thailand if you bring enough money from abroad. You might sign up for a retirement visa, if you bring enough money from abroad...You might do this and that...but only IF you bring enough money from abroad...IF you bring money from abroad. And again, IF you bring enough money from abroad.....same is true in any developing nation. What counts, is the money you bring with you and not a marriage with a Thai girl.
However, to be together with a local Thai girl is OK while staying in Thailand in your own home. Nothing wrong with that. If she wants to stay with you, it's fine, and if she wants to leave, let her go...To marry? For what?
And what might happen, if you marry? And if the girl wants a divorce?
You are still on be better side:
The Thai law says clearly, what was yours before marriage regarding real estate (in case of foreigner a condominium, as foreigners cannot own land), will belong to you after divorce. Should you really be into marriage in Thailand, make sure, that your condominium is registered legally in your name BEFORE marriage.
About money, do not bring your assets into Thailand, keep your savings overseas and never give any money to the Thai girl and her relatives to register any property or business in her name.
You should be safe...It's not easy for a girl, and not even for a wife, to send you to the cleaners in Thailand in case of separation and divorce.
