One important, but often overlooked, issue when a marriage breaks down is what will happen to your assets on your death. If you die after you have separated but before your divorce is completed, your spouse will still inherit anything they are entitled to under your will, or be the main beneficiary under the intestacy rules if you die without a will. It is a good idea to consider making a will or revising your existing will as soon as you can after separating. 

If you are unmarried and do not have a will, your partner will have no automatic entitlement to any inheritance on your death, regardless of how long you have been together and whether you have been cohabiting. It is vital for unmarried couples to have wills in place if they want their partners to benefit from their estates.
