Marriage
Marriage invalidates all Wills before the date of the marriage unless it is expressly stated in the Will that the intended marriage shall not revoke it.

Divorce
Divorce does not invalidate a Will. However, after a decree absolute (not decree nisi) any appointment of the former spouse as an Executor or Trustee is treated as omitted and all gifts to the former spouse have no effect.

Separation
Separation from a spouse without a divorce or annulment has no effect on the spouse’s rights no matter how long the separation has lasted.

Cohabitation
A cohabiting partner who has not registered a civil partnership is not normally entitled to anything unless they are specifically mentioned in the Will or they can show dependence.

Assets
A significant change of assets may require their identification and consideration given to their disposal.

Birth and Deaths
The birth of a child or death of a beneficiary may alter how the estate is to be distributed. At the same time the death of a potential guardian may also require another to be appointed.

Business
Starting your own business or becoming a shareholding director or partner in a firm will require consideration to be given as to how your interests are to be evaluated, maintained and disposed of.
