What are the consequences and costs of overstaying a visa in Thailand when wanting to marry a Thai citizen?

Swim to Malaysia. Claim passport was lost get new one.. No problems

Having can Thai girlfriend, no concern with entry visa , sound crazy

Friend went to airport to leave and get new visa with 90 days overstay, had to pay 20'000thb fine and get 1 year ban. If you go to local immigration you will still get the fine but may not get the ban.

I had a 29 day over stay 2 yr ago

I was seriously ill in hospital bed ridden for 5 weeks and totally forgot about my Visa

Although I had hospital bills totalling over 250.000 baht with dates covering my overstay, I was told not good enough and should of handed my passport to hospital staff and they would provide a letter stamped everyday As I was in a coma on life support for 11 days and completely on another planet for the next week or two Visas was not on my mind

I was told I've been taken off the system and by rights should leave Thailand with a yrs ban

However some one who knew someone set wheels in motion

I know some don't agree with backhanders but after private negotiations was allowed to stay

I don't know if it was the look on our 3 kids faces or the 10.000 baht that clinched it

you're looking at a 1 year Ban from Thailand if you turn yourself in...if you get arrested by the police you're looking a 5 year Ban...total cost of the overstay fine is 20,000 THB...good luck

One addition to Tods advice: If you surrender yourself to the authorities you will probably be able to still clear overstay without a ban however if you get arrested or caught otherwise it could result in a 5 year ban so you might want to get this sorted ASAP.

Once you do clear the overstay and are here on either a 30 day visa exempt entry or a 60 day tourist visa you would need to go to your consulate and get the affidavit of freedom to marry notary, then have it and your passport translated into thai and certified by the Ministry of Foreign Affairs office in Bangkok.

Then you could go to a local Amphur (city hall) and get married.

If you are on an overstay of under 90 days, it will cost you 20K baht in overstay fines.

Seeing as you're not married yet (meaning you can't get a marriage visa and then an extension) and having a child out of wedlock (meaning you can't use the child to get an extension) your options are limited.

The first thing you need to do is clear the overstay by exiting the country. Either get a 30 day visa exempt entry or go to a thai consulate and get a single entry tourist visa

Pay your fine and get out ASAP or you will be banned for a year.

Then get married and get marriage visa

IF you have a 90 day overstay you will be banned from entering the country for 1 year when you exit the country.
