Can I use a property that isn't in my wife's name for my marriage extension in Thailand?

When applying for a visa extension based on marriage in Thailand, it is essential to use the address you actually reside in, regardless of ownership. If the property you live in is not in your wife's name but you have a chanote (land title), this may be sufficient for your application. Immigration may inspect the property, so ensure that it's registered correctly and where you mostly live. If necessary, consider updating the house registration or providing a lease agreement in your name from your wife for the property.
