A couple in the UK should have a will to ensure their assets are distributed according to their wishes rather than intestacy rules.

It allows them to provide clearly for each other and any children, including appointing guardians if needed.

A will can help minimise Inheritance Tax (IHT) by using allowances such as the nil-rate band and spouse exemptions.

It also makes the probate process smoother and less stressful for the surviving partner.

Without a will, unmarried couples in particular may not automatically inherit anything.

Overall, having a will gives financial protection, tax efficiency, and peace of mind for both partners.
