Switching E&O carriers is almost always pitched on price, and price is the wrong thing to lead with. On a claims-made policy the number that decides your protection is not the premium. It is whether your retro date and your prior acts move with you. Get that wrong and a cheaper policy can quietly cover only the work you do from the switch forward, leaving everything behind it exposed. If the retro date mechanics are new to you, what is claims-made coverage and the retro date and claims-made retro date tail gap set up the foundation this article builds on.
What prior acts means
Prior acts generally refers to the work you did before your current policy began. Because claims-made coverage responds based on the policy in force when a claim is made, your prior acts are only protected if the retro date reaches back to when that work was done. In a stable program that happens automatically, and years of finished engagements stay covered under your current policy. The moment a switch resets the retro date, those prior acts can fall outside the new policy, even though you were insured the entire time you did them. Nothing about the work changed. The date behind it did.
How the switch resets your history
Here is the trap. A new carrier can write your policy with a retro date at the switch date by default. That policy looks fine on the declarations page, carries the limit you wanted, and costs less, which is why the firm moved. What it does not do is reach back. Unless someone specifically asks the new carrier to honor your existing retro date, or arranges prior acts coverage, the new policy starts your covered history over at today. All the work before the switch, every engagement that felt safely insured, is now behind a retro date the new policy does not cross. The savings are real. So is the hole underneath them.
Nose coverage, and how it saves the switch
The fix has a name. Nose coverage, also called prior acts coverage, generally means the new carrier agrees to pick up claims arising from work done before the new policy, back to your original retro date. It is the bridge that carries your history into the incoming policy instead of stranding it. It is worth being precise here, because two terms get confused. Nose coverage lives on the new policy and reaches backward. Tail coverage lives on the policy you are leaving and extends the window to report claims after it ends. On most switches, either preserving the retro date with full prior acts on the new policy, or arranging a tail on the old one, keeps continuity intact. Which one fits depends on what both carriers offer, and that is a conversation to have before you move, not after.
Doing the switch the right way
A clean switch is not complicated, it is just deliberate. Before the old policy ends, confirm the new policy will honor your existing retro date and provide full prior acts, or arrange nose coverage to the same effect. Do not let the new policy quietly default to a today retro date because nobody raised it. Treat continuity as a required term of the switch, on equal footing with the limit and the premium. A firm that does this moves carriers and keeps every year of its history covered. A firm that shops on premium alone can save money and lose a decade of protection in the same signature.
Questions to ask your advisor
- Will the new policy honor my existing retro date and cover full prior acts?
- Is the new carrier defaulting my retro date to the switch date?
- Do I need nose coverage on the new policy or tail coverage on the old one?
- What would happen to a claim on pre-switch work under the new policy?
- How do we confirm continuity in writing before the old policy ends?
The cheapest E&O quote is not a bargain if it starts your history over. A firm that carries its retro date and prior acts through the switch keeps the work it already did protected, instead of paying less for a policy that only looks forward.
