Estate planning UK wills how to protect your family

If you've been searching for estate planning UK wills advice, you've probably already realised that a will on its own doesn't cover everything you need to protect your family. Estate planning is the wider process of deciding what happens to your money, property, and possessions, both while you're alive and after you die.

A will is one part of that picture. A full estate plan usually also includes a lasting power of attorney, trusts where they're useful, and a plan for any inheritance tax your estate might owe. Together, these documents help make sure your wishes are followed and can reduce the chance of your family facing unnecessary stress, delay, or tax at a difficult time.

You don't need to be wealthy or own a large property portfolio to benefit. Anyone with a home, savings, children, or a partner has something worth protecting.

If you die without a will in England and Wales, your estate is shared out under the intestacy rules, not according to your own wishes. These rules follow a fixed order of family relationships and take no account of who you actually wanted to benefit.

Married couples and civil partners inherit first, followed by children, then other relatives in a set order. Unmarried partners, no matter how long they've lived together, have no automatic right to inherit anything under the intestacy rules.

Consider an unmarried couple who've lived together for 20 years, own their home jointly with a mortgage, and have two children together. If one partner dies without a will, the surviving partner may not automatically inherit their share of the property outright, and could face a claim from the deceased's children or other relatives, depending on how the property is owned. A will removes this uncertainty by stating clearly who inherits what.

Estate planning also needs to account for any mortgage or other borrowing secured against your home. Your home may be repossessed if you do not keep up repayments on your mortgage or any other debt secured on it, so any secured debts need to be factored into how your estate will be passed on.

For more detail on how the rules work in different family situations, read our guide on what happens if you die without a will, or see general guidance from Citizens Advice.

1. Your will

Your will is the legal foundation of your estate plan. It states who inherits your money, property, and possessions, names an executor to administer your estate, and appoints guardians for any children under 18. Find out more about how to write a will in the UK.

2. Lasting power of attorney (LPA)

A property and financial affairs LPA lets someone you choose manage your bank accounts, bills, and property if you lose capacity. A health and welfare LPA covers decisions about your care and medical treatment. Both matter while you're alive, not just after you die. Read our guide to lasting power of attorney.

3. Trusts

Trusts aren't necessary for everyone, but they can add real value for blended families, protecting assets against future care costs, or passing money to children in a controlled way. They add complexity and cost, so they're worth discussing with a professional rather than setting up as a default.

4. Inheritance tax planning

Every estate has a nil-rate band of £325,000 before inheritance tax applies, plus an additional residence nil-rate band of up to £175,000 if you leave your home to children or grandchildren. Anything left to a spouse or civil partner is normally exempt from inheritance tax entirely. From April 2027, inherited pension pots will also count towards your estate for inheritance tax purposes, which is a significant change for anyone who has treated their pension as separate from the rest of their estate. If your home still has a mortgage or other secured borrowing against it when you die, that debt is deducted from your estate's value before any inheritance tax is worked out, and your home may be repossessed if you do not keep up repayments on your mortgage or any other debt secured on it while you're alive. You can check current thresholds directly with HMRC's inheritance tax guidance.

There's no single right age to start estate planning. Instead, certain life events should prompt you to write or review your will and wider estate plan.

Marriage automatically revokes any existing will in England and Wales, which catches many people out. If you don't make a new will after getting married, your estate could be distributed under the intestacy rules instead of your original wishes.

Costs vary widely depending on how straightforward your estate is and who you use. A simple online will typically costs between £30 and £100. Using a professional will writer for a single will usually costs more, and a solicitor is the most expensive option but often worth it for complex estates involving business assets, overseas property, or trusts. See our detailed breakdown of how much does a will cost.

Registering a lasting power of attorney with the Office of the Public Guardian costs £82 per LPA, and most people need two: one for property and financial affairs, and one for health and welfare.

Speaking to an advisor about how your estate plan fits with your mortgage, savings, or a potential equity release plan comes with no obligation to proceed, though releasing equity from your home to help fund later-life costs will reduce the value left to your beneficiaries.

Solicitors are regulated by the Solicitors Regulation Authority, which means they carry professional indemnity insurance and are held to strict conduct standards. Will writers aren't required to be regulated in the same way. The Society of Will Writers offers voluntary membership, but joining isn't a legal requirement.

For a straightforward estate, such as a married couple with one property and no complex family circumstances, a will writer or online will service is usually enough. For more complex situations, business interests, overseas property, blended families, or significant inheritance tax planning, a solicitor or a regulated financial advisor typically adds more value. Compare the options in our guide to will writing service vs solicitor.

If you're also considering financial advice on how your estate plan fits with pensions, investments, or a mortgage, look for an advisor who is regulated by the Financial Conduct Authority. Regulated advisors must act in your best interests, and you can check anyone's authorisation on the Financial Conduct Authority register.
