The short answer: your legal malpractice insurance policy may be maturing.
Seeing an increase at your first renewal can be frustrating, especially when your firm has had no claims or major practice changes. But a higher premium does not automatically mean your firm did something wrong. In many cases, the increase is connected to how claims-made coverage develops over time.
As your policy renews, the carrier may be covering a longer history of eligible legal work through your prior acts coverage. This expanded exposure is one reason premiums can increase during the first several renewals, even when your firm’s circumstances have not significantly changed.
Below, we answer common questions about first-renewal increases, including what step-rating means, how long it may last, why your retroactive date matters, and what you can do to protect your coverage before your next renewal.
Why did my premium increase at renewal?
Your premium may increase at renewal because a lawyers professional liability policy is usually written on a claims-made and reported basis. As you renew each year, the carrier is not just covering the work you do going forward; it is also continuing to cover eligible past work back to your retroactive or prior acts date.
As your policy renews, the carrier is taking on a longer history of covered legal work. That expanded exposure is one reason a first-renewal increase may be expected, even if your firm had no claims, no major practice changes, and no obvious new risk factors.

What is the step-rate factor?
The step-rate factor is part of how many claims-made lawyers professional liability policies mature over time.
In the early years of your liability insurance policy, your premium may “step up” because your policy is covering a longer window of past legal work. Once the policy reaches a mature rate, the step-rating effect typically levels off, although other rating factors can still affect your premium.

Why does prior acts coverage matter?
Prior acts coverage matters because legal malpractice claims can arise long after the work was performed. Your retroactive date helps determine how far back your policy may respond to a claim, subject to the policy’s terms and conditions.
Maintaining that exact date through continuous coverage helps protect the legal services you have already provided. Once a gap in continuous coverage occurs, or the date is erroneously changed, it jeopardizes the coverage you’ve invested in year after year.

Why did my premium increase if I had no claims?
A no-claims year is a positive factor, but it does not always guarantee a flat renewal premium.
With claims-made coverage, the carrier’s exposure can increase because the policy continues to protect eligible past work as your prior acts coverage grows. Claims history is important, but it is only one piece of the renewal pricing picture.
The key takeaway: a clean claims history helps, but it does not erase the pricing effect of a maturing claims-made policy.
How long do premium increases last?
Step-rate increases do not last forever. They happen during the early years of a claims-made policy, when the coverage period is still being built. It’s common to see step-rate premium increases due to prior acts coverage for the first 6-8 years of a policy.
Once the policy reaches a mature rate, step-rating is typically no longer the primary driver of increases, although market conditions, limits, practice changes, claims activity, and other underwriting factors may still affect pricing.

When does my policy reach a mature rate?
A policy reaches a mature rate when the step-rate factor has fully developed, and the carrier is already rating the policy for a mature history of prior acts exposure. At that point, your premium is less likely to rise simply because the policy is one year older, but it can still change for other underwriting or market reasons.
Prior acts maturity depends on the carrier but is often reached after 6-8 years of continuous retroactive coverage.
Can I avoid step-rate increases?
You usually cannot entirely avoid step-rate increases if your policy is still maturing, because they are tied to how claims-made coverage expands over time.
Although you may not be able to avoid these increases entirely, understanding them before renewal can help you plan accordingly. You can also protect your retroactive date, avoid coverage gaps, and talk with your agent about whether your limits, deductible, practice areas, and policy details still fit your firm.
Attempting to reduce your premium by giving up prior acts protection could create a significant coverage gap. For a claims-made and reported policy, your retroactive date is part of the long-term value of the coverage you have been maintaining.
Does changing carriers affect my prior acts coverage?
Changing carriers can affect your prior acts coverage if your retroactive date is not carried over correctly. Before switching, make sure the new policy matches your existing retroactive date exactly. Even a small change could create a coverage gap for work performed before the new date, and correcting the error may not always be possible.

What happens if my coverage lapses?
A lapse can do more than interrupt your current policy. Because claims-made policies depend on continuous coverage, a lapse may jeopardize the retroactive date and the prior acts protection your firm has built over time. In some cases, the new policy may apply a new retroactive date, potentially leaving past work uninsured.
It’s important to understand the cost of a lapse in coverage and how to prevent gaps in your insurance to protect your practice.
What should attorneys know before their next renewal?
Before your next renewal, know that an increase does not automatically mean something is wrong with your firm or your claims history. Ask your agent whether the change is related to step-rating, prior acts exposure, limits, deductible, practice areas, market conditions, or another underwriting factor.
Maintaining continuous coverage and an accurate retroactive date helps protect the legal work your policy has covered over time.
Bottom Line
During the first several years of a claims-made legal malpractice insurance policy, annual premium increases may be tied to the growth of prior acts coverage. Your premium may also be affected by other factors, including changes in your practice, market conditions, claims activity, and underwriting considerations.
Once your policy reaches a mature rate, growing prior acts exposure is typically no longer the primary reason for an increase. Future premium changes may be driven by factors such as:
- Changes in areas of practice
- Claims history
- Market conditions
- Underwriting appetite
- Carrier rate changes
If your renewal premium increases, ask your agent whether step-rating or prior acts exposure contributed to the change. Understanding what is driving the increase can help you make a more informed renewal decision.
Most importantly, do not remove or shorten your prior acts coverage date solely to reduce your premium. For claims-made and reported policies, continuous coverage and an accurate retroactive date are critical to protecting eligible work performed before the current policy year. This is especially important with lawyers’ professional liability insurance because claims may arise months or even years after the legal services were provided.
Quick Checklist: Questions to Ask Your Agent Before Your Next Renewal
- Is this increase related to step-rating or prior acts exposure?
- Did my limits, deductible, practice areas, or revenue affect the quote?
- Has my retroactive date remained exactly the same?
- Are there coverage changes I should understand before renewing?
- If I change carriers, will my existing prior acts coverage be preserved?
