Accurate property valuations have become one of the most critical parts of probate administration. Property is often the largest asset in an estate, and HMRC now treats it as a high-risk area for potential undervaluation.
Recent research reported in Today’s Wills & Probate shows a 23.5% increase in cases referred to the Valuation Office Agency (VOA) – rising from 11,845 to 14,631 referrals in the year to 30th September 2025. This sharp rise reflects HMRC’s growing determination to challenge valuations that previously would have been accepted without question.
For executors, this shift brings a significant risk. If HMRC decides a property has been undervalued, the estate may face additional inheritance tax, interest charges, and in some cases, personal liability for the executor.
How Lawson West’s Probate Team Helps Protect Executors
A probate solicitor does far more than complete forms. They actively reduce the risk of costly mistakes by providing expert guidance throughout the valuation and reporting process.
Ensuring HMRC Compliant Valuations
Solicitors understand HMRC’s expectations and can advise on the most appropriate valuation method. In many cases, this means instructing a RICS‑qualified surveyor rather than relying on a high‑street estate agent’s estimate. A professional valuation alone can prevent disputes with the VOA.
Identifying Red Flags Early
Certain features can trigger HMRC scrutiny, including:
Development potential
Unusual or unique property characteristics
Recent renovations or improvements
A solicitor can identify when a valuation needs additional evidence or justification.
Managing HMRC and VOA Correspondence
If HMRC challenges the valuation, a solicitor can:
Handle all communication
Provide supporting documentation
Negotiate with the VOA
Prevent executors from making accidental admissions
This protects both the estate and the executor.
Protecting the Executor Personally
Many executors are unaware they can be held financially responsible for errors. A solicitor ensures:
Accurate reporting
Compliance with deadlines
Minimised tax exposure
Reduced risk of personal liability
Common Pitfalls That Trap Lay Executors
These seemingly small mistakes can lead to major problems later:
Relying on informal estate agent estimates instead of a professional valuation
Failing to disclose property defects or improvements
Misunderstanding “open market value”
Using outdated sale prices as a benchmark
Missing HMRC deadlines, resulting in interest charges
Assuming HMRC will not question the valuation – despite challenges rising sharply
With HMRC now far more proactive, these are no longer minor oversights. They can materially affect both the estate and the executor.
The Bottom Line
A probate solicitor provides more than administrative support. They offer risk management, technical expertise, and protection at a time when HMRC scrutiny is intensifying. For executors, especially those acting for family or friends, this guidance can be the difference between a smooth administration and a stressful, costly investigation.
