Death and Wills are generally not a topic of conversation when you are preparing for your wedding.
Marriage significantly changes property division and the allocation of assets.
A new marriage invalidates a Will made before the marriage.
So you should reconsider documents such as Wills and Contracting Out Agreements (“Pre-Nuptial Agreements”).
Estate planning should be reviewed before marriage as it will be affected by the marriage as well. Your review should look at who will benefit from your estate and gifts.
If your documents do not reflect your wishes, then that can have negative consequences for everyone.
