Online Will vs Solicitor UK 2026: Which Should You Choose?

The question of whether to use an online will service or a solicitor is one of the most common in UK estate planning. The honest answer depends entirely on your individual circumstances. For the majority of UK adults, an online will is perfectly adequate, legally valid, and represents extraordinary value. For others, a solicitor's expertise is genuinely necessary.

This guide gives you a clear framework to make the right decision, with a frank comparison of costs, risks, and suitability.

Head-to-Head Comparison

When an Online Will is the Right Choice

For most UK adults, an online will writing service is not just adequate — it is genuinely the best option. You are a good candidate for an online will if:

Your estate is straightforward

• You own property in the UK only
• Your assets are primarily: a home, bank accounts, ISAs, pension, car, personal possessions
• Your total estate is unlikely to exceed £325,000 (or £500,000 with the RNRB if leaving your home to children)
• You have no business interests beyond standard employment

Your family situation is clear

• You are married or in a civil partnership with your first/only partner
• All your children are from your current relationship
• There are no disabled beneficiaries who need a trust to protect their benefits
• There is no anticipated dispute among beneficiaries

Your wishes are simple

• Leave everything to your partner, then to your children
• Or split between named beneficiaries in clear percentages
• No complex conditions or contingencies

If all of the above apply, an online will from LegalWills.co.uk or a similar reputable service will serve you perfectly well at a fraction of solicitor cost.

When You Should Use a Solicitor

There are specific circumstances where the additional cost of a solicitor is clearly justified — and some where it is essential:

You need a trust in your will

Discretionary trusts, life interest trusts, vulnerable beneficiary trusts, and other trust structures are complex to draft correctly. Errors can have significant legal and tax consequences. Online services cannot handle these adequately.

Your estate is IHT-liable

Estates above £325,000 (or £500,000 for homeowners leaving property to children) may face 40% IHT. A solicitor can advise on: nil-rate band trusts, RNRB eligibility, business property relief (100% or 50%), agricultural property relief, lifetime gifts and the 7-year rule, and charitable giving to reduce the IHT rate to 36%.

You have business interests

Business ownership — shares, sole trade, partnership — needs careful will planning. Business Property Relief (BPR) can provide 100% IHT relief on qualifying assets, but this must be structured correctly in the will.

You own property abroad

Foreign property is governed by local law, not UK law. You may need separate wills in each country. Your UK solicitor can coordinate with local lawyers to ensure your global estate is properly handled. See our guide on wills for British expats.

You have a blended family

Where children from previous relationships need specific protection, or where the surviving spouse might divert assets away from your children, a solicitor can structure appropriate protective trusts.

Your testamentary capacity might be questioned

If you are elderly, have a diagnosis affecting cognitive function, or if there is any risk that relatives might challenge your capacity to make a will, a solicitor should attend the signing and prepare a contemporaneous capacity record. This is the most effective way to challenge-proof a will.

A beneficiary or dependent might contest your will

Under the Inheritance (Provision for Family and Dependants) Act 1975, certain family members and dependants can challenge a will if they believe it fails to make reasonable provision for them. If this risk exists, a solicitor can advise on how to structure and document the will to minimise this risk.

The "Good Enough for Now" Approach

For many people in transitional life stages, a pragmatic approach is to create an online will immediately as a baseline — then revisit with a solicitor when circumstances warrant it. This is particularly sensible for:

• Young couples just starting out, with modest assets but wanting their partner protected
• New parents who urgently need to appoint a guardian but don't yet have complex assets
• Anyone who has been putting off writing a will for years

A will you create online today is infinitely better than the perfect solicitor will you don't get around to making for another three years.

Regulation and Consumer Protection

This is one area where solicitors have a genuine advantage. Solicitors are regulated by the Solicitors Regulation Authority (SRA), which means:

• They carry professional indemnity insurance
• You have recourse to the Legal Ombudsman if things go wrong
• Strict conduct rules apply

Online will writing services are not currently required to be SRA-regulated. However, reputable services like LegalWills.co.uk have operated since 2000 and have strong track records. Look for services that are members of the Society of Will Writers or the Institute of Professional Willwriters, both of which have voluntary codes of practice.
