Claims made coverage and why the prior acts date is the first number to read
Legal malpractice insurance for solo attorneys is nearly always written on a claims made basis. This means the policy only covers claims first made and reported during the effective policy period. The date when your coverage first started without gaps is called the prior acts date, or sometimes the retroactive date. Every policy's declaration page will show this, often just above the premium itself.
The prior acts date matters because it determines the earliest point in time for which the policy will respond to a claim. If a lawsuit or demand involves work done before that date, your current carrier will not cover it. For solos, keeping continuous claims made coverage is critical. A gap, even for a few days, can reset the prior acts date, leaving years of prior work uninsured. When reviewing quotes, look for the prior acts date shown and make sure it matches or precedes the date you first bought a policy, not just the current term.
Insurers also use the prior acts date in their pricing model. The longer your uninterrupted coverage, the more years of risk the insurer is taking on. Each additional year adds to the "exposure base" for the underwriter. Early-career solos may see lower premiums because their prior acts date tracks recent licensing, while older practices with decades of coverage might pay more for the same policy limits, given the cumulative risk.

How per claim and aggregate limits are quoted and what they cap
Malpractice policies are quoted with two main limit numbers: per claim and aggregate. Per claim is the most the insurer will pay for any single claim or lawsuit, no matter how many people sue you or how many ways the alleged error played out. Aggregate is the total amount the insurer will pay for all claims across the policy period, usually one year.
For solo attorneys, the most common limits shown on quotes are $100,000 for each claim to $300,000 for all claims in a year, or $250,000 per claim to $500,000 aggregate. Some policies offer $1 million per claim to $1 million aggregate. The higher the limit, the higher the premium. This is a direct arithmetic relationship: if you double the limits, the premium typically increases, but not by a full double. Insurers use their own algorithms, but a solo raising limits from $250,000 to $1 million per claim will see a noticeable jump in cost.
Be aware that defense costs, attorney bills for defending you, may either come out of these limits or be paid outside of them, depending on your policy. A policy with defense costs inside the limits can see the available coverage for settlements or judgments shrink quickly if a case drags on. Always check how the policy handles this, as it affects both risk and rating.
Deductibles, and whether yours absorbs defense costs
A deductible is what you pay out of pocket before the insurer pays anything on a claim. For solos, deductibles often start at $1,000 and range to $10,000 or more. Lower deductibles increase the premium, since the insurer is on the hook for more minor claims. Raising the deductible can shave dollars off the bill, but only do so if you have cash reserves to pay it when needed.
The next question is whether your deductible is "first dollar" or "loss only." A first dollar deductible applies both to indemnity payments, the money paid to settle or pay a judgment, and to defense costs. If the deductible applies to defense, you could be writing checks for the lawyer defending you from day one. In contrast, a loss only deductible means the insurer covers defense costs from the first bill, and the deductible only comes into play if you lose or settle the claim.
Some policies also offer "aggregate deductibles," which cap your out-of-pocket exposure for the policy period, no matter how many claims come in. For a solo with a thin operating margin, knowing whether deductibles apply to defense costs, indemnity, or both is crucial. Insurers factor deductibles into premium calculations: the higher the deductible, the lower the premium, all else being equal.

Practice area mix as the heaviest single rating factor
Not all practice areas carry the same risk of malpractice claims. Insurers track, and price, based on your mix of work. For solos, this is usually reported as a percentage breakdown by area: for example, 70 percent family law, 20 percent estate planning, 10 percent real estate.
Certain areas, such as securities, intellectual property litigation, or plaintiff's personal injury, are rated as high risk. These areas see more frequent and expensive claims. A solo focusing on wills, probate, or simple real estate closings will see lower base rates. If you do even a small percentage of high-risk work, the insurer's model may rate your whole policy at the higher rate, or blend the rates based on your percentage. This is why the application always asks for detailed breakouts, sometimes down to the exact number of hours spent in each category.
How to document your practice area mix
It is good practice to track your work and keep clear notes on the type of cases handled each year. If an insurer challenges your reported mix after a claim, you will want documentation. Many insurers also re-evaluate your mix at each renewal. A shift in your practice, such as taking on one large plaintiff's case, can move you into a higher rate band.
Credits for experience, risk management courses, and a clean claims history
Insurers offer credits, reductions in premium, for factors that decrease their risk. The first is years in practice. Solos who have practiced for a decade or more, especially with a clean record, often qualify for experience credits. The assumption is that mistakes are more likely early on, and that seasoned attorneys have better systems and judgment.
Another credit is for completing approved risk management or loss prevention courses. These may be online or in-person and cover topics such as docket control, client communication, and file management. Insurers believe attorneys who take these seriously are less likely to face claims. Some carriers require a certificate of completion for the credit to apply at renewal.
Finally, a clean claims history is one of the strongest factors. If you have never had a malpractice claim or disciplinary complaint, that history goes a long way. Even one claim can raise premiums or limit your options. Insurers will ask for ten years of claims history on the application. Providing accurate, documented answers is essential. Failing to disclose past matters can later void your coverage.

What a tail policy costs as a multiple of your last annual premium
When you retire, die, merge, or simply stop practicing, your claims made policy does not cover future claims for past work unless you buy an extended reporting period endorsement, commonly called a tail policy. This gives you coverage for claims arising from work done before your last policy ended, reported after you close shop.
Tail policies are typically priced as a multiple of your last annual premium. For example, the standard offering is a three-year tail for a set percentage of the departing attorney's final premium. Some carriers offer tails for one, three, five, or unlimited years. The longer the reporting window, the higher the cost. For solos, a full unlimited tail is usually the most expensive option, but it gives peace of mind that no matter when a claim surfaces, coverage remains.
It is important to budget for this one-time purchase. Some carriers allow payment in installments, others require the full amount up front. If you have had a long claims-free record, you may qualify for a reduced tail rate, especially if you are retiring. Always check the contract language and secure written confirmation of your tail policy, as this cannot be added later if a claim appears after the policy lapses.
The renewal application question about your conflicts procedure
One common question on malpractice insurance renewals concerns your method of screening for conflicts of interest. Insurers want to know that you have a written procedure for checking new matters against your client database, and that you document the process. This is because conflict-related claims, such as representing parties with adverse interests, are a frequent source of lawsuits against solos and small firms.
Many insurers will ask if you use a structured intake form for each new matter, and whether you keep a dated record of each conflict check. Some applications request details about the software or system in use. If you cannot describe a consistent process, or lack documentation, underwriters may see you as higher risk. This can nudge premiums upward, or in some cases, lead to a refusal to quote.
For most solo attorneys, a spreadsheet or paper log is common. However, as practices grow, the risk of missing a conflict increases. Automated systems with searchable databases and audit trails reduce the chance of error and provide the kind of record insurers like to see. A dated screening record gives you evidence of diligence if a dispute later arises.
These requirements are not just about reducing claims, they also show the insurer how you run your business. A structured intake form with automatic adverse party conflict search and a dated screening record satisfies what underwriters look for, and can support a strong renewal application.
