If you already have a Will
It is important that you revisit your Will as separation to ensure that your Will accurately reflects how you wish for your assets to be distributed in the event of your passing.
If your current Will includes provisions that benefit your former spouse, these will continue to remain in place regardless of separation. For this reason, it is extremely important that you update your Will if you no longer wish for your former spouse to benefit from your estate.
Once you have finalised your Divorce, some of the provisions contained within your Will no longer have effect, however you should seek legal advice to confirm whether this is the case for you.
