Why do I need professional indemnity insurance?

By law anyone offering a professional service must exercise the required skill to an appropriate level expected by that profession. However, professionals are only human and sometimes mistakes do happen.

Any financial loss, injury or damage arising from an act, error or omission by the professional during the provision of their advice or service could result in a claim for compensation against them for any loss suffered by a third party.

You may also be required to hold a professional indemnity insurance policy as a condition of member of a professional association, as a contractual requirement or to maintain an accreditation or license.

What protection does professional indemnity insurance provide?

It safeguards your own financial position in the event of a claim by covering the legal defence costs and any compensation awarded as damages in court or as part of a settlement.

What does it mean that this is a "claims made" policy?

This means that any fact, situation or circumstance that may result in a claim needs to be notified to the insurer within the period of insurance.

The actual error (or alleged error) that the claim relates to must have occurred after the retroactive date noted on the policy.

The insured must not have had any prior knowledge of the fact, situation or circumstance before the period of insurance, or they must have disclosed this to the insurer at the inception, or at renewal, of the policy.

What is continuous cover?

Continuous cover is essentially a loyalty bonus. It means that if someone who was insured with an insurer in unbroken successive periods notifies the insurer of a claim or circumstance in a subsequent period (but which should have been notified in an earlier period), then that claim will be covered under the later policy. If the limit of indemnity had changed between the two periods the lower limit would apply.

‘Non-disclosure’ issues and ‘known circumstances’ exclusions will not be raised. However, prejudice due to delayed notification may be taken into account in the adjustment of the claim.

What is considered a "circumstance" that would require notification?

The test of what is a ‘claim circumstance’ and whether it ought to be notified is an objective one. That is, would a reasonable person in the position of the insured have realized that the circumstances may give rise to a claim?

When in doubt, notify the insurer, especially if the events in question give you cause to be concerned that a claim may arise. In circumstances where you are aware of your negligence, it is no excuse for the late notification of a claim circumstance simply to wait and see if a formal complaint is made.

What is automatic reinstatement?

This allows the aggregate limit of cover under the policy to be increased after a claim. It means that while a single claim can’t exceed the policy limit, a second claim may be allowed, up to the same limit of cover. The sum of both claims may not exceed the aggregate limit and both claims must be below the limit of indemnity.

What is a retroactive date?

The retroactive date is the date after which acts, errors or omissions of the insured are covered.

That is, any act, error or omission arising from work done after the retroactive date will be covered under the policy (subject to policy terms and conditions).
