In short

  • Decide on your executor, guardian arrangements and beneficiaries before you start.
  • A will must be in writing, signed, and witnessed by two people to be valid.
  • You need mental capacity and freedom from pressure when you sign.
  • Review your will after major life events such as marriage, divorce or having children.

Making a will involves deciding who should benefit from your estate, who should administer it, and putting those decisions into a document that meets the legal requirements for a valid will in England and Wales. It sounds daunting, but for most people the process is more about making a handful of clear decisions than dealing with complicated law.

You can make a will through a solicitor or through an online service such as My Posh Will, which costs £69 for an individual will or £89 for mirror wills, and typically takes around ten minutes to complete online before signing.

Decide who your executor will be

Your executor is responsible for administering your estate after you die: collecting in assets, paying debts, and distributing what is left according to your will. Choose someone organised and willing to take this on, and name a backup in case they cannot act when the time comes. Many people choose a spouse, adult child or close friend, sometimes alongside a professional executor for more complex estates.

It is worth asking the person before naming them, since being an executor involves real work, from registering the death and valuing the estate to completing tax forms and eventually distributing money to beneficiaries. Someone who feels ambushed by the role after your death is less likely to deal with it smoothly than someone who agreed to it in advance and understands roughly what is involved.

Decide who inherits, and in what shares

Think about any specific gifts you want to make, such as a sum of money to a friend or a particular item to a family member, and then decide how the residue of your estate should be divided. The residue is everything left once debts, funeral costs and specific gifts are accounted for, and most wills leave this in defined shares to one or more beneficiaries, with a backup named in case a beneficiary dies before you.

If you have children under 18, you can also name a guardian in your will to look after them if both parents are no longer around, which is one of the most important reasons parents choose to make a will.

When thinking about specific gifts, be as precise as possible. "My engagement ring" is clearer than "my jewellery" if you own several pieces, and "£5,000 to my nephew James Smith" is clearer than simply "some money to James", particularly if more than one person in the family shares that name.

Put it in writing and meet the legal formalities

Section 9 of the Wills Act 1837 sets out what makes a will valid: it must be in writing, signed by you with the intention that your signature gives effect to the will, and signed or acknowledged in the presence of two witnesses who are both present at the same time. Each witness must then also sign the will, in your presence.

You also need testamentary capacity when you sign, meaning you understand what a will is, roughly what you own, and who might expect to benefit, and you must not be under pressure from anyone else to make the will a particular way.

  • Put the will in writing (typed is fine, it does not need to be handwritten)
  • Sign it yourself, or direct someone to sign for you in your presence
  • Have two independent witnesses present at the same time
  • Each witness signs afterwards, in your presence

Store it safely and tell someone where it is

Once signed, keep your will somewhere safe and dry, such as a fireproof box at home, with a solicitor, or in a will storage service, and make sure your executor knows where to find it. A will that cannot be located after death can cause serious delays and expense for your family.

When to get professional advice

If your estate might be liable for inheritance tax, includes business or agricultural assets, property abroad, a blended family, a likely dispute, or a dependant who cannot manage their own affairs and needs a trust, you should speak to a solicitor rather than relying solely on a standard will.

What a will does not need to cover

Some assets pass outside your will regardless of what it says. Property owned as joint tenants usually passes automatically to the surviving owner, and life insurance or pension death benefits are often paid according to a separate nomination form held by the provider, not by the will. It is worth checking these arrangements alongside making a will, since assuming your will controls everything can lead to gifts you intended not actually reaching the person you had in mind.

This does not make a will less important, since most people still have savings, personal possessions and sometimes property held in their sole name that do need to be dealt with through the will, alongside the guardianship and executor decisions a will alone can make.
