I bought 200 rais without docs. just the contract between buyer /seller and I own it I can do anything I want, farming, (built one house on it) and I can sell it if I choose, I benefit from the land by leasing it to the farmer and you can not develope it, the purpose is for agriculture only at this time have to wait untill the zone changed then you can obtain the red deed and make big profit

If you are Thai, you can the risk and if everything goes well make big profit in a few years.
Buying land without documents is a gamble for every foreigner, and I doubt strongly that a foreigner could make benefit of it.

Go to the city of record where the land is located and check the title.

By now, you will know that I'm a foreigner and showing my face in any Land Departement Office for these purposes is a "no-no".
My wife will have to make the change of destination at the local Land Departement Office and do all the paperwork.

When the change of land status is occurred meant from green to red deed it is recorded at local city record where the land is located.

I will believe you on this, and let my wife try to change the document from GREEN to RED.
If they would agree at the local Land Department (which at this "electoral" moment is almost 99% sure), I can start buiding our house.

Thanks for your useful replies,
