DIY Will vs Professional Will Writer: What You Are Actually Comparing
A DIY will vs Professional Will Writer cost comparison is really a comparison between two very different products: a blank document you complete yourself, and a professional service that drafts, checks and stores a legal document for you. At Staniland Estate Protection, we see the consequences of that difference regularly. The headline price of a DIY will is only the entry point. GOV.UK guidance on making a will is clear that a will must be signed and witnessed correctly to be valid, and getting that wrong is where the real cost appears.
The Real Cost of a DIY Will
A DIY will is a template or online form you complete yourself, usually for a modest one-off fee or free. The purchase price is low, but it excludes your time, the risk of an error, and the cost of putting it right later. Many people find the wording options harder than expected once children from a previous relationship, a buy-to-let property, or a business interest are involved.
The Real Cost of a Professional Will Writer-Written Will
A Will writer-written will is a professionally drafted document prepared after a consultation about your circumstances. Professional will writing fees vary with complexity, so pricing depends on your situation rather than a fixed rate. What you are paying for is drafting accuracy, advice on the points you had not considered, and a document that will hold up when it matters.
The Risks of DIY Wills: Why Cheap Can Cost More
The risks of DIY wills centre on validity and interpretation. A will that is signed incorrectly, witnessed improperly, or worded ambiguously can be challenged, partially invalid, or fail to do what you intended. Common mistakes include using a witness who is also a beneficiary, failing to account for a spouse or civil partner's position, and not updating the will after a major life change.
Professional Will Writing Fees: What You Pay For
Professional will writing fees cover more than the document itself. A typical service includes an initial consultation, advice on your specific circumstances, drafting, a review meeting, correct execution, and secure storage. Fees are usually quoted per will or as a pair for couples, and they rise with complexity such as trusts, multiple properties, or cross-border assets.
Because every firm structures its fees differently, ask for a written quote before instructing anyone.
How to Make a Valid Will UK: The Legal Requirements
To make a valid will in the UK, you must be 18 or over, of sound mind, and the will must be in writing, signed by you, and signed by two witnesses who are present at the same time. Those witnesses cannot be beneficiaries or the spouses or civil partners of beneficiaries. the Wills Act 1837 sets out these formal requirements, and they apply whether you write the will yourself or pay a solicitor to draft it.
The practical steps are straightforward:
- Decide who will inherit and who will act as executor
- Choose two witnesses who are not beneficiaries
- Sign in front of both witnesses, together
- Have both witnesses sign in your presence
- Store the original safely and tell your executor where it is

Frequently Asked Questions
Is a DIY will legally binding in the UK?
A DIY will is legally binding in the UK if it meets the legal requirements: it must be made by someone aged 18 or over, signed by the testator in the presence of two witnesses, and those witnesses must also sign in the testator's presence. The will must be in writing and the testator must have mental capacity. However, a legally binding will can still be poorly drafted, leaving assets to the wrong people or failing to account for tax. Many DIY wills that appear valid on the surface cause problems during probate because of ambiguous wording or missed legal formalities.
What are the risks of using a DIY will kit?
The risks of DIY wills include unclear or ambiguous wording that courts must interpret, failure to account for inheritance tax, missed updates after major life changes, and inadequate provision for vulnerable beneficiaries or minor children. DIY wills also often fail to appoint guardians properly or to set up trusts that protect assets for children from previous relationships. If the will is challenged or found invalid, the estate may be distributed under intestacy rules, which may not reflect your wishes. A solicitor can spot these issues before they become expensive problems for your family.
How much does a Professional Will Writer charge for a simple will?
Professional will writing fees vary widely depending on the complexity of your estate, your location, and the firm you choose. A straightforward single will might cost a few hundred pounds, while a pair of mirror wills or a will involving trusts, business assets, or foreign property will cost more. Some Will writers charge a fixed fee, while others bill hourly. Because pricing depends on your individual circumstances, it is best to ask for a written quote before instructing anyone. Staniland Estate Protection can provide a tailored quote based on your needs.
When should you use a Professional Will Writer instead of a DIY will?
Use a Professional Will Writer when your estate is not straightforward. This includes owning property, having children from more than one relationship, owning a business or buy-to-let property, having assets worth more than the inheritance tax threshold, or wanting to set up trusts. A Professional is also essential if you need to appoint guardians for minor children, provide for a vulnerable beneficiary, or plan for care fees. A DIY will can work for very simple estates, but the cost of fixing a poorly drafted will often exceeds the cost of having it written properly from the start.
