What Is a Retroactive Date on Professional Liability (E&O)?

A retroactive date is the earliest work date your Professional Liability (E&O) policy covers. This guide is for consultants and service businesses who are renewing or switching policies.

What does a retroactive date mean on Professional Liability?

Professional Liability is almost always claims-made. It pays for claims made and reported while the policy is active, and only for work done on or after the retroactive date. Coverage for work done before the policy started, but after the retroactive date, is called prior acts coverage. See claims-made vs occurrence for the difference.

Technology E&O, media liability, and lawyers or medical malpractice policies are also usually claims-made with a retroactive date. Some contracts spell out what they expect:

• "On or before the effective date": the date must be no later than the day the contract or the work started.
• "Shall not be advanced": the date cannot be moved later, which would cut off earlier work.
• "Three years after completion": you keep the same or an earlier date for three years after the work ends.

Who asks for a specific retroactive date?

Clients that hire consultants, agencies, IT firms and designers often write the retroactive date into the contract. Lenders and general contractors may do the same. Check any contract that asks for "prior acts" or "continuous coverage."

Long projects and repeat work make the date matter more, because a claim may name work from years ago. Does your contract say how far back the date must go?

What happens if my retroactive date resets?

A retroactive date is usually set when you first buy Professional Liability. It often carries forward if you renew or switch without a gap, but it can reset if coverage lapses or a new insurance company (a carrier) offers only its own start date.

Take a hypothetical consultant with a 2020 retroactive date. In 2026 she moves to a new policy with a 2026 date. In 2027, a client sues over work she did in 2024. The new policy likely does not cover it, and her old policy has ended.

How do I find my retroactive date on my policy?

• Look at the declarations page, the summary page at the front of the policy.
• It may show a specific date, "Full Prior Acts" or "None". Either of the last two may mean the policy has no cutoff for past work. Claims you already knew about are usually still excluded. Check the policy wording before you rely on it.
• If it matches the policy start date, the policy may not cover anything you did before that day. That is common on a first policy.
• A certificate of insurance (the one-page proof of coverage you send to clients) has no standard field for the retroactive date, though some add it in the description box when a contract requires it. See certificates for Professional Liability.

How do I keep my retroactive date when I switch policies?

Send Morrow your current policy so the date is clear before quotes are requested. Morrow can then compare each quote's date and prior acts wording with it.

Before you switch, report any known incidents (a client complaint, a mistake or a threat to sue) to your current carrier. A new policy usually excludes matters you already knew about. If a later date is the only option, ask Morrow about tail coverage. It covers claims first made after the old policy ends, for work done while it was in force. The policy sets a deadline to buy it, usually a short window after the old policy ends, so check your wording.

What will underwriters ask for?

Underwriters (the staff who decide whether to offer coverage and on what terms) often ask for:

• Your current policy and declarations page, showing the retroactive date
• Proof of continuous coverage, meaning no gaps between policies
• Loss runs, which are reports showing your past claims
• A signed statement that you know of no incidents that could lead to a claim

What affects the cost?

• How far back the date goes, since more past work means more chances for a claim
• Whether your services have changed, and your claims history
• The limit you need and your retention, the amount you pay on a claim before the policy pays
• Your revenue and the size of your largest projects

Frequently asked questions

Can I get an earlier retroactive date on Professional Liability?

Only sometimes. Any change depends on the carrier's underwriting and the policy wording. It usually comes at renewal or with a new carrier, and carriers often want a clean claims history and a signed statement of no known incidents. It may cost more.

Does an excess layer have its own retroactive date?

It can. An excess layer is extra coverage that sits on top of your main, or primary, policy. It should follow form, meaning it uses the same terms as the primary policy, including its retroactive date. Some list their own date, so check it. See Professional Liability limits explained.

How long should my retroactive date stay the same?

Many contracts ask you to keep the same or an earlier date for a set time after the work ends, often for several years. Check the clause in your contract. Morrow can review it with your current policy.
