Can my Thai spouse provide a lease or rental agreement for a house we built together instead of using living expenses for my visa extension?

No, you can't lease land/house from a Thai spouse.

Sounds like a hassle.

You own house and lease land - better protection and still ok with immigration.

Not sure what you are asking for. You can get your wife to put you on the house book, get your own yellow house book and pink id card. When i did this they didn't ask for visa details. The hard bit it proving you are married; if you got married abroad your marriage cert will need translating to Thai and then approved by the Thai embassy in your home country.

You need ฿500,000 for the DTV but it's good for 5 years. You have to leave Thailand once every 180 days but don't need a re-entry and only need the 500k for initial application and when you renew in 5yrs. Needs to be in your account for 3 months prior to application and the lease would be your proof of residence.

If you like to go to the gym you can do the Muay Thai "soft power" DTV or the "Festival" DTV which is used for concerts/events. Each has their own checklist. Google can easily help you out.

I know someone who did this as an easy way of proving where they lived for visa extension and then after many years his wife apparently received a tax bill for the 'rent' he paid her. If you are just thinking about documents for the visa extension then what I do is get my wife to sign a letter/declaration in Thai stating that we live together in the same house and she comes with me to do the renewal. I'm on a retirement extension not a marriage extension and it's gone without a hitch for the last 14 years, in Pattaya and now in Khon Kaen.

Are you having to get a lease agreement for a house you paid to have built?

yes a lease on the house not the land -

She can get you a House book from the local Governmet office. It is of much more benefit.
