Finishing Another Firm’s Project. What Happens to Your Professional Liability When You Stamp Drawings You Didn’t Start

Short answer

Taking over another architect’s project insurance questions usually start with the seal. When you take over a project another firm started, and especially when you seal its drawings, you may become responsible for work you did not do. A new contract with a start date helps, but it may not cleanly split liability if a claim mixes old and new work. Insurers care a lot about how far along the project is. Options can include declining, limiting your scope or buying a project-specific policy. Whether a policy responds depends on its wording and the facts.

Why taking over another architect’s project happens often

Firms close, principals move and owners change designers. A project that is fully drawn still needs someone to carry it through permit and construction.

Taking over early, during predesign or schematic design, is common and usually manageable. Taking over late is where the questions get harder. That means drawings are complete, the permit is pending or construction is about to start. Insurers tend to look closely at this stage.

What sealing the drawings means for your exposure

In most states, the professional who seals drawings takes professional responsibility for them. Reviewing and stamping work someone else prepared can make it your work in the eyes of the client and a court. Sealing rules vary by state, so confirm what your state board allows before you agree to seal anything you did not prepare.

The same logic applies to engineers who stamp a design they did not start. Our article on what happens after stamping someone else’s design covers how an error can reach you after the seal goes on.

Why a new contract with a start date may not be enough

Many firms try to sign a new agreement saying they are only responsible from a certain date. That agreement defines what you agreed to do for the owner.

A claim is a different matter. If a problem shows up, it can be very hard to separate a flaw in the earlier drawings from an issue in the later work. That makes it hard to know which policy, if any, should respond.

For this reason, insurers often prefer that projects already well underway stay with the original firm or arrangement. They tend to favor new firms taking on new projects only. Our article on bringing a 1099 architect into your firm is not linked here because its address is not confirmed, so ask your agent how your insurer handles in-progress work.

When the original firm has closed

If the original firm closed, its policy may have ended. Claims-made coverage generally needs a policy in force, or an extended reporting period (tail), when the claim is made. Our article on the extended reporting period on an A&E policy explains how tail coverage works.

Ask whether the closed firm bought tail coverage. If it did not, a claimant may have nobody else’s policy to look to except yours.

Get the release of the drawings in writing from the owner and, if possible, from the original firm. The paperwork matters if the question of who owns and can reuse the drawings comes up later.

Your options when you take over another architect’s project

You have several ways to handle the request, and the right one depends on the project.

Decline or wait: You can pass on the job or wait for a project that is earlier in design.
Narrow the scope in writing: You might limit your role to code review only or construction administration only. Avoid sealing work you did not prepare where your state rules allow.
Ask your insurer first: Some insurers may consider the project with more information and possibly more premium. Many will not.
Project-specific professional liability: This is a policy written for one job. Underwriters usually want detailed information, and availability for a project that is already designed varies.
Ask the owner to help: The owner might carry an owner’s protective or project policy, or pay for the project-specific policy as part of the fee.

What an underwriter will want to see

If you ask about project-specific coverage, expect the underwriter to request details like these:

Project description, size and status, such as permit, bidding or construction
Total construction value and remaining fees by discipline
Exactly what services you will perform and whether you will seal the drawings
Contracts with the owner and consultants, including indemnity and insurance clauses
Who prepared the earlier work and whether you are taking responsibility for it
Delivery method and a list of every firm on the team, with roles
Confirmation that consultants carry professional liability, and their limits
Desired limit, deductible, start date and expected project length
Any known problems, claims or disputes on the project

Having this ready speeds up the conversation. Our contract check can help you spot indemnity and insurance clauses worth raising.

Questions to ask your agent

Would my practice policy respond to work I seal but did not prepare?
Did the original firm have tail coverage, and how can I find out?
Is a project-specific policy available for a project that is already designed?
What information will the insurer need, and how long will it take?
Should I tell my insurer before I sign, even if I decide not to take the job?

General education, not legal advice. Hardcover is an insurance agency, not a law firm. Whether a policy responds depends on its wording and the facts.

Am I responsible for drawings I stamp but did not prepare?

Often, yes. Sealing drawings usually means taking professional responsibility for them. Check your state board’s rules before you agree.

Will my professional liability cover a project I took over from another firm?

It depends on the policy wording and the facts. Insurers often have concerns about projects transferred mid-stream, so ask your agent before you sign. Our professional liability insurance page explains the coverage in general.

Does a new contract with a start date protect me from the earlier work?

It defines your scope. It may not cleanly separate old and new work if a claim comes in.

What if the original firm has closed?

Its policy may have ended. Ask whether it bought tail coverage.

Can I buy a policy just for one project?

Sometimes. Project-specific professional liability exists, but underwriters want detailed information. Availability for a project that is already designed varies by insurer.
