When you make a Will, it's important to keep it up-to-date to take into account any changes in your circumstances. The most common changes of circumstances that may affect your Will are:
getting married, remarried, or registering a civil partnership
getting divorced, dissolving a civil partnership, or separating
the birth or adoption of children
the death of a beneficiary
obtaining any new significant assets (eg a house)
If you do not change your Will after a marriage or the registration of a civil partnership, your existing Will is still valid. However, since 1 November 2016, getting divorced or ending a civil partnership does affect a Will. If you have left a gift in your Will to your spouse or your civil partner, it will not take effect if you later get divorced or end your civil partnership.
