In short

  • A last will and testament and a will are the same thing under English law.
  • It names an executor, beneficiaries, and sets out how your estate is shared.
  • It must meet the Wills Act 1837 formalities to be legally valid.
  • The most recent valid will replaces any earlier ones you made.

'Last will and testament' is the traditional full name for what is usually just called a will: a legal document that sets out what should happen to your money, property and possessions after you die, and who should be responsible for carrying out your wishes. The word 'last' simply means it is the most recent one you have made, since a new valid will cancels any earlier ones.

You do not need to use the phrase 'last will and testament' for a document to be legally effective; what matters is that it meets the formal requirements set out in law. My Posh Will lets you create one online for £69, or £89 for mirror wills between partners, in around ten minutes.

What a last will and testament typically contains

A will generally opens by identifying you and stating that it revokes any earlier wills. It then names your executor or executors, the people responsible for administering your estate, and sets out any specific gifts you want to make, such as a sum of money to a friend or an item of jewellery to a relative.

After specific gifts, the will deals with the residue: everything else in your estate once debts, funeral costs and specific gifts have been accounted for. If you have children under 18, the will can also appoint a guardian to look after them.

Many wills also include a small number of standard administrative clauses, such as who should pay any outstanding debts and funeral expenses before the residue is calculated, and a clause dealing with what happens if a beneficiary dies before you. These clauses are easy to overlook when thinking about a will in everyday terms, but they are what allow an executor to deal with practical questions without having to guess your intentions.

  • Revocation clause cancelling earlier wills
  • Appointment of executor(s), including a backup
  • Guardianship provisions for children under 18
  • Specific gifts and the residue clause

Legal requirements for validity

Under the Wills Act 1837, a will must be in writing, signed by the testator (the person making the will) with the intention of giving effect to it, and signed in the presence of two witnesses who are both present at the same time, each of whom must then sign the will in the testator's presence.

The testator must also have testamentary capacity, understanding broadly what they own, who might expect to benefit, and the effect of making a will, and must be acting freely and without undue influence from anyone else.

These requirements apply equally whatever the document is called. Some people still refer to a will as "putting your affairs in order" or "drawing up a testament", but none of these phrases changes the legal test that is actually applied when the will is read after death.

Why it needs to be your most recent version

Because a new valid will revokes earlier ones, it is important that only your current will is kept and that old versions are destroyed to avoid confusion. Marriage automatically revokes an earlier will unless that will was made in contemplation of the marriage, so this is a common point where people find their existing will is no longer valid.

What happens without a valid last will

If you die without a valid will, you are said to have died intestate, and the intestacy rules decide who inherits your estate regardless of your actual wishes. This can mean an unmarried partner receives nothing, or that your estate is divided in ways you would not have chosen, which is why having a valid, up to date will matters even for modest estates.

When to seek legal advice

A straightforward last will and testament can usually be prepared online, but you should see a solicitor if your estate might be liable for inheritance tax, includes a business or farmland, foreign property, a blended family situation, likely disputes, or a dependant who cannot manage their own affairs and may need a trust set up for them.

How a last will and testament is used after death

After death, the executors named in the will apply for a grant of probate, a court document confirming their authority to deal with the estate. They use the original signed will to show who should receive what, collect in money and property, pay any debts and taxes due, and then distribute what remains according to the will's instructions.

Because the will is the document everyone relies on at this stage, clarity matters more than legal-sounding language. A will that clearly states who gets what, in plain terms, causes far fewer problems during probate than one written in vague or old-fashioned wording that leaves room for different interpretations.

Wording that causes problems later

Certain phrases cause more disputes than others. Leaving something to "my children" without naming them can cause confusion if a child is later born, adopted, or estranged. Leaving a percentage of residue without stating what happens if that beneficiary dies first can leave a gap in the will. Being specific and including backup provisions for every gift avoids most of these issues.

It is also worth avoiding conditions that are difficult to prove or enforce, such as vague behavioural conditions on a gift. Clear, straightforward wording that an executor can act on without needing to interpret your intentions tends to cause far fewer problems than wording that sounds meaningful but is hard to apply in practice.
