Making a statutory declaration to establish non UK domicile
If you leave the UK, you may well be looking to avoid Inheritance tax. One of the best ways to achieve this is to lose your UK domicile status.
As regular readers will know, if you're a UK citizen 'born and bred' you will be likely to have UK domicile of origin. In order to lose this you will need to establish a domicile of choice overseas.
This is a combination of actually having your chief residence overseas and having the intention to remain there for the rest of your days.
Establishing your intention is a matter of fact and the Revenue/courts would be likely to look back at your life and attempt to infer your overall intentions.
Your expressed intentions are not conclusive as the courts would look at your actions to determine your intention, not your statements (ie you would need to act as though you wanted to live overseas forever rather than simply saying that your intention is to reside permanently overseas).
Nevertheless your express statements are certainly taken into account, and therefore if you do wish to lose your UK domicile by establishing an overseas domicile of choice, making a statement to this effect can be persuasive.
One of the preferred ways of making such a statement is by making a statutory declaration. It's more formal than a simple deed and would need to be notarised (eg by a solicitor). When taken with other evidence that actually supports your overseas domicile it can be highly advantageous in persuading the Revenue that you established a non UK domicile of choice. A sample statement showing the kinds of things that could be covered is shown below.
