Good morning from the UK. I have a question for UK expats in making a will.
Im presently living in the UK with 2 half Thai/British dual nationality children. I am thinking of making a will in the uk but it is our intention to move back to Thailand in 3 years time once my children have completed their GCSE exams.
Looking at making a will in the UK but not sure if the will will be recognised in Thailand or will I need to make a seperate will in Thailand?
Most of my assets will remain in the uk but also not sure about taxation when I eventually pass. Will there be tax to pay in both countries or would tax only be paid in one country and if so which one?
Thank you so much   

Need a separate will in Thailand for any assets or funds held in Thailand. If no assets then no problem.

whale is correct. you should have separate wills;

uk will for uk assets to uk citizens ( your kids)

thai will for thai assets to thai citizens ( wife & kids ).

 no crossover. no conflicts. keeps things simple.

structure your assets and wills accordingly
