DIY Probate vs Using a Solicitor: The Real Cost Comparison (2026)
Applying for probate yourself avoids solicitor fees, but a complex estate, disputed will, or Inheritance Tax return can make DIY probate a genuine risk. A worked 2026 comparison.
The DIY route
Executors named in a will (or administrators, where there's no will) can apply directly for the Grant of Probate (or Letters of Administration) via gov.uk's online or paper service, provided they can correctly value the estate's assets and liabilities, and complete any required Inheritance Tax reporting. A probate application fee applies above a set estate value threshold β check gov.uk for the current fee and threshold β plus a small charge for extra copies of the grant, often needed to deal with several banks or asset holders simultaneously.

- Inheritance Tax reporting errors β a full IHT account for larger or more complex estates requires accurate valuation of all assets (including property, investments, and sometimes gifts made in the years before death) β getting this wrong can trigger penalties or an incorrect tax bill.
- Business or agricultural assets β these can qualify for specific reliefs, but correctly claiming them requires care that a DIY approach may miss.
- Disputed or ambiguous wills β where beneficiaries disagree, or the will's validity is in question, professional legal involvement is generally essential, not optional.
- Assets abroad or complex trust structures β these add legal and tax complexity well beyond the standard DIY probate process.
Executor personal liability
A crucial point often underestimated: executors are personally liable for correctly administering the estate β this includes ensuring the right tax is paid before distributing assets, and not distributing to beneficiaries in a way that leaves insufficient funds to cover a later-discovered debt or tax liability. This personal exposure is one of the strongest reasons a complex estate should involve professional advice, even if the executor is confident with paperwork generally.

Some solicitors and probate specialists offer a "grant only" service β helping specifically with the legal application for the Grant of Probate, while the executor handles the rest of the estate administration (contacting asset holders, distributing to beneficiaries, closing accounts) themselves. This can be a genuine cost-effective middle ground for executors comfortable with the administrative work but wanting professional help with the legal application itself.
A practical framework
| Estate situation | Suggested route |
|---|---|
| Simple estate, clear will, below/near IHT threshold, no disputes | DIY probate is often reasonable |
| Complex IHT position, business/agricultural assets, disputes, assets abroad | Full solicitor involvement recommended |
| Confident with admin but want help with the legal application | "Grant only" service as a middle ground |

Frequently asked questions
Can I apply for probate myself without a solicitor?
Yes β executors can apply for the Grant of Probate themselves directly through the gov.uk online or paper probate service, without needing a solicitor, though the estate still needs to be correctly valued and any Inheritance Tax return completed accurately before applying.
How much does the probate application fee cost?
There's a probate application fee for estates above a certain value threshold, payable regardless of whether a solicitor is used β check gov.uk for the current fee and threshold, plus the cost of any extra copies of the grant needed to deal with multiple asset holders.
When does DIY probate become risky?
DIY probate becomes considerably riskier where the estate is large or complex enough to require a full Inheritance Tax account, where there are disputes among beneficiaries, where the will is unclear or potentially invalid, or where the estate includes business assets, trusts, or property abroad.
