Most people put off estate planning for one simple reason: it sounds like a conversation about death, and nobody wants to have that conversation on a Tuesday afternoon. But strip away the discomfort and what you’re really deciding is something much more practical who gets what, when, and with how much hassle. That’s it. Let’s break down wills and trusts without the legal fog.
Why Do I Need a Will?
A will is a legal document that sets out exactly who inherits your money, property, and possessions when you die and without one, the government decides for you, not your family. Rules of intestacy (what happens when someone dies without a will) don’t care about your actual relationships. An unmarried partner of 20 years can walk away with nothing, while distant relatives you barely spoke to can inherit by default. A will simply puts you back in control of a decision that’s currently on autopilot.
Beyond who inherits what, a will also lets you:
- Name guardians for children under 18
- Choose your executors the people responsible for carrying out your wishes
- Leave specific gifts to friends, charities, or organisations
- Reduce the chance of family disputes after you’re gone
What Is a Family Trust?
A trust is a legal arrangement where assets money, property, or investments are held and managed by appointed trustees on behalf of chosen beneficiaries, according to rules you set out in advance. Instead of assets passing directly to someone the moment you die, a trust can control how and when they’re received.
Family trusts get used for situations a simple will doesn’t handle well, such as:
- Protecting an inheritance for children until they reach a certain age
- Ring-fencing assets for a vulnerable family member
- Keeping wealth within the family across generations
- Protecting property from being counted toward care home fee assessments
- Managing assets for a beneficiary who isn’t ready (or able) to manage a lump sum themselves
What Is the Difference Between a Will and a Trust? (The Core Distinction)
This is the question almost everyone actually wants answered, so here’s the plain version:
| Will | Trust | |
| When it takes effect | Only after you die | Can start during your lifetime or after death |
| What it controls | A one-time instruction for distributing assets | Ongoing control over how and when assets are used |
| Probate involved? | Yes, typically | Assets in trust often bypass probate |
| Privacy | Becomes a public document via probate | Stays private |
| Best for | Straightforward estates and clear wishes | Complex situations protecting assets, minors, care fee planning |
Put simply: a will says “here’s what happens to my things when I die.” A trust says “here’s how these specific assets should be managed, for how long, and for whose benefit potentially starting right now.” Many people use both together rather than picking one over the other.
What Is a Lasting Power of Attorney (LPA)?
An LPA isn’t a will or a trust, but it’s part of the same conversation, so it’s worth clearing up here. A Lasting Power of Attorney is a legal document that lets you appoint someone to make decisions on your behalf if you lose the mental capacity to make them yourself while you’re still alive. There are two types: one covering health and welfare decisions, and one covering property and financial affairs.
Without an LPA in place, your family may need to apply to the Court of Protection to gain the legal authority to act for you a process that’s slower, more expensive, and more stressful than setting up an LPA in advance ever is.
Mirror Wills The Option Most Couples Don’t Know Exists
For married couples or long-term partners, mirror wills are two nearly identical wills that leave everything to each other, with the same instructions for what happens if both partners die. They’re simple, cost-effective, and solve the most common estate planning need for couples without requiring a trust structure at all.
Do I Need Both a Will and a Trust?
Not everyone does and that’s genuinely fine. A single, well-drafted will covers most people’s needs perfectly well. Trusts tend to make sense when:
- You own property you want to protect for your children specifically
- You’re worried about future care home fees affecting what’s left to inherit
- You have a blended family and want to control inheritance carefully across both sides
- You want to protect a beneficiary who might struggle to manage a large inheritance responsibly
If none of those apply to your situation, a properly written will (paired with an LPA) may be all the estate planning you actually need.
Inheritance Tax: The Part Nobody Enjoys But Everyone Should Understand
Both wills and trusts play a role in inheritance tax planning. Certain trusts can help reduce the taxable value of an estate over time, while a well-structured will can make use of allowances and exemptions that reduce what’s owed. This is one area where professional advice pays for itself many times over inheritance tax rules are detailed, and small structuring decisions now can make a meaningful difference to what your beneficiaries actually receive later.
A Simple Way to Decide What You Need
Ask yourself: is my situation straightforward (one estate, clear beneficiaries, no complicating factors), or is there something specific I need to protect, control, or delay? The first points toward a will. The second usually points toward adding a trust. Either way, getting professional will writing and estate planning advice means these documents are legally valid, clearly worded, and actually do what you intend rather than leaving your family to interpret ambiguity at the worst possible time.
Frequently Asked Questions
Why do I need a will? Without a will, intestacy rules decide who inherits your estate, which may not reflect your actual wishes. A will also lets you name guardians for children and choose your executors.
What is the difference between a will and a trust? A will is a one-time instruction that takes effect after death and typically goes through probate. A trust provides ongoing management of assets, can start during your lifetime, and often bypasses probate.
What is a family trust? A family trust is a legal arrangement where trustees hold and manage assets on behalf of chosen beneficiaries, often used to protect inheritances, support minors, or plan around future care costs.
What is a Lasting Power of Attorney (LPA)? An LPA is a legal document allowing you to appoint someone to make health or financial decisions on your behalf if you lose mental capacity, while you’re still alive.
Do I need both a will and a trust? Not necessarily. A will alone suits many straightforward estates, while a trust becomes useful for more complex situations like protecting property, minors, or planning around care fees.
