Will writers and estate planners: unregulated work, decade-delayed consequences
Unregulated does not mean low-risk
Because will writing sits outside the reserved legal activities, anyone can offer it — and the absence of a regulator means nobody compels a will writer to carry PI the way solicitors are compelled. Online forms read “unregulated” as “simple” and offer a thin, generic policy or none at all. But the severity profile points the other way: the product is a legal instrument on which an entire estate depends, the client base is often elderly, and the error rate is only ever measured at the worst possible moment. A will that fails — badly executed, ambiguous, out of date against the family’s real circumstances, silent on assets it should have caught — can misdirect everything the client owned.
The long fuse: why claims-made mechanics dominate
Most professions get their complaints quickly. Will writers get theirs when the client dies. The gap between the negligent act and the claim can be twenty or thirty years, and PI is claims-made: the policy that responds is the one in force when the disappointed beneficiaries come forward, not the one in force when the will was drafted. Three consequences follow. Cover must be continuous — a gap in cover is a gap in protection for every will ever written. The retroactive date must reach back to the start of the practice, and must be preserved when insurers change. And when the business eventually closes or the principal retires, run-off cover is not optional housekeeping; it is the only thing standing between past drafting and personal exposure.
Estate planning and the IHT dimension
Modern will-writing businesses rarely stop at wills. Trusts, lifetime gifting strategies, property arrangements and inheritance tax planning are part of the offer — and they change the risk. Tax planning advice produces losses that are easy to quantify: if the planning fails, the additional tax paid by the estate is the claim, with figures that scale with the estate. An insurer rating a “will writer” has not necessarily rated an “estate planning adviser”, and the description of business on the schedule should name every activity — will drafting, trust creation and administration support, IHT planning advice, lasting power of attorney work — so that nothing the firm actually does sits outside the described activities.
The boundary with reserved legal activities
The line that keeps a non-solicitor practice safe is the line around the reserved legal activities — probate activities, the conduct of litigation and the other activities that only authorised persons may carry on. A will-writing business that drifts across that line, even helpfully, is committing a criminal offence and standing entirely outside anything its insurance contemplated. The disciplined answer is a clear scope of service: draft the will, advise on the planning, and hand matters requiring an authorised person to a solicitor — with the referral recorded. Insurers ask about this boundary for good reason, and a firm that can evidence its discipline presents a materially better risk.
What a proper programme looks like
PI sized against estate values rather than fee income; described activities covering the full service line; continuity and retroactive cover checked rather than assumed; run-off planned before it is needed; and ordinary business covers — office, cyber for a client base full of sensitive personal and financial data — around it. None of this is exotic. It just is not what a dropdown menu produces, because the dropdown has no way to ask when your mistakes surface. Ours does: it is a conversation.
FAQ
Is will writing regulated in the UK?
Will writing itself is not a reserved legal activity, so it can be carried on without being a solicitor. Some will writers belong to voluntary trade bodies with their own standards. What is reserved — probate activities, the conduct of litigation and other reserved legal activities — must not be carried on by someone who is not authorised, and a will-writing business needs to know exactly where that line sits.
Why does claims-made cover matter so much for will writers?
Because the error and its discovery can be decades apart. A defective will is typically only tested when the client dies. PI responds on the policy in force when the claim is made, so the business needs continuous cover with a retroactive date reaching back over all past drafting — and run-off cover when it eventually stops trading.
Do I need run-off cover if I retire or close the business?
Yes, in almost every case. Closing the business does not close the exposure; wills drafted years ago will still mature into claims. Run-off cover keeps a claims-made policy answering claims that arrive after the doors shut, and the number of years of run-off to buy is a real decision, not a formality.
Does PI cover inheritance tax planning advice?
Only if that activity is declared and described. IHT planning is advice about tax outcomes, and errors can produce quantifiable six- or seven-figure losses to an estate. A policy described as “will writing” alone may not contemplate it — the schedule should say what the business actually advises on.
Who actually brings a claim about a defective will — the client has died?
Typically the disappointed beneficiaries or the estate. The person who instructed the will is gone by the time the defect surfaces, which is part of why these claims are hard-fought and why the drafting file — attendance notes, instructions, capacity observations — is the will writer’s main defence asset.
