Short Answer
A professional liability name change doesn't necessarily require a completely new insurance policy. The key question is whether you changed the name of the existing legal entity or created an entirely new company. If the underlying entity stays the same, the carrier may only need to update or endorse the policy. Either way, tell your broker before or immediately after the change so the carrier can determine how it wants it documented.
Same company, new name
Suppose Smith + Jones Architects, LLC becomes Jones Studio Architects, LLC. The firm keeps the same LLC, EIN, ownership structure, contracts, and operations. That's a very different situation from shutting down Smith + Jones Architects and starting a brand-new company.
If the underlying entity remains the same, professional liability insurance for the name change may involve a straightforward endorsement rather than a new policy. Don't assume that filing the new name with the state automatically updates your insurance. The carrier needs to be told separately.
What about work performed under the old name
This matters most for architects and engineers, since a project designed under a former business name can produce a claim years later. A firm going through a name change may still have projects under construction, active contracts, completed projects, certificates issued under the former name, and contracts that reference the old name throughout.
Your broker should notify the professional liability carrier about the change and confirm how services performed under the former name will be treated going forward, including whether the policy still responds to a claim tied to a project completed under the old name.
When it gets more complicated
Tell your broker if the name change also involves any of the following:
- A new LLC or corporation
- A new EIN
- An ownership change
- A partner leaving
- A merger or acquisition
- Dissolution of the existing firm
Any of these can raise additional questions involving prior acts, predecessor firms, retroactive dates, and extended reporting periods. A name change alone is usually simpler to document than a change involving a new legal entity, so it's worth being clear with your broker about exactly what happened.
Example
An architecture firm rebrands from Smith + Jones Architects, LLC to Jones Studio Architects, LLC. The LLC, EIN, and ownership stay the same, and no new entity is formed.
The firm has several projects completed under the old name and one currently under construction. The broker notifies the carrier of the name change and confirms the endorsement needed to update the policy, along with how a claim tied to a project completed under the former name would be handled. Handling this before a claim happens, rather than after, avoids uncertainty about which name the policy actually recognizes.
What to check before or after a name change
- Confirm whether the legal entity is staying the same or a new one is being formed
- Notify your broker of the change as soon as it happens
- Ask what endorsement or documentation the carrier requires to reflect the new name
- Confirm how the policy treats work performed and contracts signed under the former name
- Flag any related changes, such as ownership shifts or a merger, separately from the name change itself
Related Questions
Do I need a new policy if my architecture firm changes its name?
Not necessarily, if the underlying legal entity stays the same. An endorsement updating the name may be enough. Confirm this with your broker.
Does changing my firm's name with the state update my insurance automatically?
No. Filing a new name with the state doesn't notify your insurance carrier. That has to be handled separately with your broker.
What happens to claims from projects completed under my old firm name?
This depends on how the carrier treats the name change and the policy's terms. Your broker should confirm this directly with the carrier rather than assuming continuity.
Is a name change the same as forming a new company?
No. A name change to an existing entity is different from dissolving one company and creating another. The distinction affects how the insurance change is handled.
What if my name change also involves a new partner or ownership change?
Tell your broker about every change involved, not just the name. Ownership changes, mergers, or a partner leaving can raise separate questions about prior acts and retroactive dates.
