Like said above. You must have a Thai will and a Will from your country of Residence. You will have to pay Thai tax on the profits from the sale of your home here in Thailand from what I’ve heard. Best to go speak with a lawyer to do your Thai Will so it is officially legal and is in Thai and English, but probate will take time. I had been put down as an executor for a friend who passed and he had a will and owned several condos. It was a long almost 2 year process to get everything resolved. The will was old and he didn’t complete his new one so they only honored the signed Will and a couple ex’s got a condo even though on his last draft of the will removed them. So please make sure that it’s up to date because you never know when you’re going to kick the bucket. Also it’s good that you kept receipts of all incoming transactions. That helps, but it’s still a lengthy process. Make sure you have your home Will also up do date. It has nothing to do with your Thai assets, but just make sure. Good luck
