Does Professional Indemnity Insurance Cover Legal Defence Costs?
Yes—Professional Indemnity Insurance may cover legal defence costs for a covered claim. However, the answer depends on the policy wording, the nature of the allegation, your policy limit, exclusions, excess and whether defence costs are included within or payable in addition to the limit of indemnity.
This distinction is important. A business can incur substantial costs responding to an allegation of professional negligence even where it has done nothing wrong. Solicitors, barristers, expert witnesses, investigations, document reviews and court proceedings can all be expensive before a matter is resolved.
Australian Government guidance confirms that Professional Indemnity Insurance can help cover the cost of legal action arising from claims about professional advice or services. business.gov.au guidance

What legal costs can PI Insurance cover?
Subject to the policy terms, Professional Indemnity Insurance may help cover costs involved in investigating, defending, settling or responding to a covered claim. This can include:
Solicitors’ and barristers’ fees
Court and tribunal costs
Expert witness fees
Claim investigation costs
Costs of responding to allegations of professional negligence
Defence costs for an insured civil claim
Settlement costs or compensation payable under a covered claim
In some policies, costs connected with certain inquiries, complaints or regulatory matters
Cover is not automatic. The claim must fall within the policy’s insuring clause and comply with its notification conditions, exclusions, limits and other requirements.
Are legal defence costs covered if the allegation is false?
Potentially, yes. One of the key benefits of Professional Indemnity Insurance is that it may help with the cost of defending an allegation, even when you dispute liability or the allegation is ultimately unsuccessful.
The cost of defending a claim can arise long before a court decides whether a professional was negligent. For consultants, accountants, architects, engineers, mortgage brokers, IT professionals and other service businesses, this is often as significant as the risk of a final compensation payment.
Do not admit liability, agree to a settlement or incur substantial defence costs without following the policy’s claims-notification process. Insurers may have rights around the conduct of the defence and appointment of legal representatives.
What is the difference between costs-inclusive and costs-exclusive PI cover?
This is one of the most important questions to ask when comparing Professional Indemnity Insurance.
Costs-inclusive Professional Indemnity Insurance
With a costs-inclusive limit, legal defence costs are paid from within the policy limit.
For example, if you have a $1 million PI limit and $250,000 is spent on legal defence costs, only $750,000 may remain available for compensation or settlement of the claim.
Costs-exclusive Professional Indemnity Insurance
With a costs-exclusive limit, legal defence costs may be payable in addition to the policy’s stated limit of indemnity, subject to the policy wording.
Using the same example, a $1 million claim limit may remain available for compensation, with covered legal defence costs paid separately.
This can materially affect the real level of protection your business has. A policy with the same stated limit may provide very different outcomes depending on how it treats defence costs. This is why selecting cover based on price alone can be risky.
Do legal costs reduce my PI policy limit?
They may. If your policy is costs-inclusive, defence costs can erode the amount left to settle a claim. If it is costs-exclusive, they may be paid in addition to the limit.
You should check:
Whether defence costs are inclusive or exclusive of the limit
The limit per claim and in the aggregate
Whether the policy has reinstatements
Your excess and whether it applies to defence costs
Any sub-limits for inquiries, investigations or extensions
Whether claimant costs are treated differently from your defence costs
For registered tax practitioners, the Tax Practitioners Board’s stated minimum aggregate PI requirements are inclusive of legal and defence costs—an example of why this detail cannot be overlooked. TPB PI requirements
What may not be covered?
Professional Indemnity Insurance does not cover every legal dispute. Depending on the policy, exclusions or limitations may apply to:
Known claims or circumstances not disclosed before cover begins
Deliberate, dishonest or fraudulent conduct
Fines, penalties or criminal matters
Work outside the professional services declared to the insurer
Contractual liabilities assumed beyond your ordinary legal liability
Bodily injury or property damage, which may require Public Liability Insurance
Cyber incidents, privacy breaches or data restoration costs, which may require separate cyber cover
Claims arising from work completed before the retroactive date
The policy schedule and wording always control what is covered.
What should you do if a client threatens a claim?
If you receive a complaint, demand, letter of allegation, request for compensation or any circumstance that might reasonably lead to a claim:
Do not ignore it or wait until formal proceedings start.
Review your PI policy’s notification requirements.
Notify your insurer or broker promptly.
Keep all relevant emails, contracts, reports, file notes and correspondence.
Avoid admitting liability or offering a settlement without insurer approval.
Obtain legal advice where appropriate.
Late notification can jeopardise cover under a claims-made policy. The right response depends on the policy and circumstances.
Choosing Professional Indemnity cover that protects your business
A Professional Indemnity policy should be assessed on more than its advertised limit. The treatment of legal defence costs, declared professional services, retroactive date, exclusions, sub-limits and notification conditions can all affect whether the policy responds when it matters.
