New rules contained in EU Regulation No 650/2012 on jurisdiction are applicable to the succession of persons who die on or after 17 August 2015.
This means that UK residents with property or assets in the European Union may be unknowingly choosing English inheritance laws over local rules.The Inheritance (Provision for Family and Dependants) Act 1975 may apply in other EU countries if you die domiciled in UK.
If you have an English Will it means you are automatically choosing English law. You should consider making a new Will or altering your current Will to make clear which property and assets in Europe you do not want English law to apply to.
Your inheritance plans may also need to be reviewed to take advantage of potentially valuable new rights and to think about how local tax laws will apply to the estate however it devolves because this may lead to more or less inheritance tax being payable.
