UK Will Witnesses and Validity Rules

The signing requirement

The Wills Act 1837 requires the testator to sign the will, or to acknowledge an existing signature, in the presence of two witnesses present at the same time. The testator must be 18 or over and have testamentary capacity. The signature can be the testator's normal signature, mark, or initial; the test is the intention to sign.

The witnessing requirement

The two witnesses must both be present when the testator signs (or acknowledges). They must then each sign or acknowledge their own signature in the testator's presence. The witnesses do not need to read the will or know its contents; they need only witness the signing.

Who can be a witness

Witnesses must:

be 18 or over;

have the mental capacity to understand what they are doing;

be able to see the testator sign.

Witnesses cannot be beneficiaries under the will or the spouse/civil partner of a beneficiary. Beneficiary witnessing invalidates the gift to that beneficiary under section 15 of the Wills Act but does not invalidate the rest of the will.

Practical implications

Witnesses should ideally be unrelated to the testator and not stand to benefit under the will. A typical choice is neighbours, friends, or work colleagues. Family members can witness provided they are not beneficiaries.

Remote witnessing during COVID-19

From 31 January 2020 to 31 January 2024, regulations temporarily allowed witnessing by video link. The witnesses needed to clearly see and hear the testator sign in real time. The provisions have now ended; standard physical witnessing applies again.

What happens with improper execution

A will that does not meet the Wills Act requirements is invalid. The deceased is treated as having died intestate, with the intestacy rules distributing the estate. The court has no general power to admit informal documents to probate; the requirements are strict.

Acknowledging the will

The testator does not need to sign the will in the presence of the witnesses. They can sign first, then acknowledge their signature in the presence of two witnesses present at the same time. This is sometimes useful for accessibility or practical reasons.

Storage

The original signed will is required for probate. Storage options include the testator's solicitor, the National Will Register, a bank's strong room, or carefully at home where the executors know how to find it.

The Wills Act 1837 in detail

The Wills Act 1837 has remained the principal statute governing will execution in England and Wales for nearly two centuries. Section 9 of the Act sets out the formal requirements: the will must be in writing; signed by the testator (or by another person at their direction in their presence); the signature must be made or acknowledged in the presence of two witnesses present at the same time; and each witness must attest and sign the will (or acknowledge their signature) in the presence of the testator.

The strictness of the section 9 requirements has been confirmed in numerous appellate cases. Marley v Rawlings (Supreme Court 2014) addressed the situation of two spouses each signing the wrong will (their partner's will), holding the wills invalid on a literal interpretation but admitting them to probate through rectification. The decision illustrates both the strictness of the Act and the limited equitable jurisdiction to remedy clear errors.

The Law Commission has reviewed the Wills Act in successive projects on Wills Reform. Recommendations have included allowing electronic wills, expanding the court's dispensing power to admit informal documents to probate, and modernising the witness requirements. As of 2026, no comprehensive reform has been enacted; the section 9 requirements continue to apply.

Section 15 beneficiary witnesses

Section 15 of the Wills Act 1837 provides that any gift to a witness (or the witness's spouse or civil partner) is void. The gift fails but the rest of the will is not affected; the gifted property typically falls into the residue of the estate. The rule is designed to prevent witnesses from benefiting from the wills they witness, on the principle that disinterested witnesses are more reliable.

The practical effect can be harsh: a well-intentioned beneficiary asked to sign as a witness loses their gift entirely. Probate practitioners typically check the witness list against the beneficiary list before submitting the will for probate. Where the testator has named the same person as both witness and beneficiary, the standard remedy is to redraft the will with different witnesses.

Section 15 does not apply where the witness is paid (such as a solicitor witnessing a client's will) or where the witness has only a fiduciary or trustee role under the will rather than a beneficial interest. Where the will provides for trustees to receive remuneration for their services, the remuneration is not a gift in the section 15 sense and is not affected.

Disputed validity and probate caveats

Where the validity of a will is disputed, a caveat can be entered at the Probate Registry to prevent a grant of probate while the dispute is resolved. The caveat lasts 6 months and can be renewed. A warning and appearance procedure under rule 44 of the Non-Contentious Probate Rules 1987 is used to test whether the caveat should remain in place pending substantive proceedings.

Disputed validity claims are brought in the Chancery Division of the High Court under CPR Part 57. The standard claims are: lack of testamentary capacity; lack of knowledge and approval; undue influence; fraud; or improper execution. Each ground has its own evidence requirements and burden of proof; the leading authority on capacity remains Banks v Goodfellow (1870).

The IHT regime: rates, bands, and reliefs

UK inheritance tax is charged at 40 percent on estates above the available nil-rate bands under the Inheritance Tax Act 1984. The standard nil-rate band is GBP 325,000 per individual, frozen until 2030 under successive Budget announcements. The residence nil-rate band (RNRB) of up to GBP 175,000 applies where a qualifying residential interest passes to direct descendants on death.

Both bands are transferable between spouses and civil partners. A married couple or civil partners can therefore shelter up to GBP 1 million on the second death where the home passes to direct descendants. The RNRB tapers above GBP 2 million of estate value, reducing by GBP 1 for every GBP 2 of estate over the threshold and being extinguished entirely for estates above GBP 2.35 million (or GBP 2.7 million in the transferable case).

Where at least 10 percent of the estate (after exemptions and the nil-rate band) is left to charity, the IHT rate on the rest of the estate falls to 36 percent from 40 percent. The reduced rate is intended to incentivise charitable legacy planning and has been used widely since its introduction in 2012.

Lifetime gifts and the 7-year rule

Gifts during lifetime above the annual exemptions are potentially exempt transfers (PETs) and fall outside the estate after 7 years. Gifts made between 3 and 7 years before death benefit from taper relief on any tax above the available nil-rate band: 20 percent reduction in IHT for gifts 3 to 4 years before death, rising to 80 percent reduction for gifts 6 to 7 years before death.

The annual exemptions cover smaller gifts without using the 7-year clock. Each individual has a GBP 3,000 annual exemption per tax year (which can be carried forward one year if unused). Small gifts up to GBP 250 per recipient per tax year are exempt. Wedding gifts are exempt: GBP 5,000 from each parent to a child marrying, GBP 2,500 from grandparents, GBP 1,000 from anyone else.

Gifts out of normal expenditure from surplus income are exempt without time limit if the donor establishes a regular pattern and retains a reasonable standard of living. The exemption is particularly useful for high earners with surplus income they wish to pass to family on a regular basis. Documentation establishing the regular pattern is essential for the exemption to apply in practice.

Business Property Relief and Agricultural Property Relief

Business Property Relief (BPR) reduces the IHT value of qualifying business assets by 50 or 100 percent. The 100 percent relief applies to interests in an unincorporated business, shares in an unquoted trading company, and shares in a quoted trading company where the deceased had control. The 50 percent relief applies to controlling shareholdings in quoted trading companies and certain other assets used in a business.

Agricultural Property Relief (APR) reduces the IHT value of agricultural property by 100 or 50 percent. The 100 percent relief generally applies to owner-occupied farmland; the 50 percent relief applies to tenanted farmland under certain conditions. The relief covers the agricultural value, not necessarily the full market value where development potential exists.

The Autumn Statement 2024 announced reforms to BPR and APR from April 2026, including a GBP 1 million combined cap on 100 percent BPR/APR. Above the cap, relief reduces to 50 percent. The reforms are being implemented through Finance Bill legislation and are expected to reshape estate planning for business owners and farmers significantly.

Wills, intestacy, and probate

A UK will must be in writing, signed by the testator, and witnessed by two adults present at the same time under section 9 of the Wills Act 1837. Beneficiary witnesses (or their spouses) invalidate the gift to the beneficiary under section 15, though the rest of the will stands. Marriage automatically revokes a prior will unless made in contemplation of the new marriage; divorce treats gifts to the former spouse as if they predeceased.

Intestacy rules under the Administration of Estates Act 1925 (as amended) follow a statutory hierarchy where there is no valid will: spouse and civil partner first with a statutory legacy of GBP 322,000 for deaths from 26 July 2023; then biological and adopted children sharing the residue; then more remote relatives. Step-children are not included in the intestacy hierarchy.

Probate is the process of obtaining authority to administer the estate. The executors named in the will apply to the Probate Registry; where there is no will, letters of administration are granted to the next-of-kin. The Probate Registry application fee is GBP 300 from January 2022 for estates above GBP 5,000. Solicitor probate fees typically run from 1 to 3 percent of estate value for full probate services.

Trusts in estate planning

UK trusts are widely used in estate planning. Bare trusts give the beneficiary an immediate absolute interest. Interest in possession trusts give a beneficiary a right to income with capital passing later. Discretionary trusts give trustees discretion over which beneficiaries to benefit and when. Most lifetime trusts (other than bare trusts and disabled persons trusts) fall within the relevant property regime: entry charges of up to 20 percent on creation, periodic 10-year charges of up to 6 percent, and proportionate exit charges.

Will trusts (created on death by the will) include life interest trusts giving a surviving spouse a right to occupy the family home with capital passing to children later, and discretionary trusts giving trustees flexibility over how the estate is distributed. Will trusts have their own tax treatment that depends on the structure.

The Trust Registration Service operated by HMRC under the EU Fifth Money Laundering Directive requires most UK trusts to register with HMRC. Beneficial ownership information is held on the register, accessible to law enforcement and certain other authorities. Limited exemptions apply for some trust types.
