Spanish Law and Succession

I have a client who is born in Tenerife but resident and domiciled in England and Wales. He has UK assets of circa £800K and a property that he recently inherited in Tenerife. He wants to leave the majority of his assets to his children. He does have a spouse.

I will need to speak with a specialist with regards to the property in Tenerife which is worth approx £1million.

Any suggestions please
