If you own property in the EU you may be advised to revisit your Wills and make sure that you are not affected by the automatic succession rules that apply in many countries. For example, in France it is the usual practice to ensure that property is left to children rather than the surviving spouse.
Recent changes in EU law and practice mean that you can now nominate the jurisdiction that you wish your EU property to be ruled by. This may mean a change to your current Will in the UK, or by creating a second Will to cover your EU property.
In effect, citizens are able to choose whether the law applicable to their succession should be that of their last habitual residence or that of their nationality.
