LPL calculator: How much does legal malpractice insurance cost?

Why Do Law Firms Need Professional Liability Insurance?

Every client engagement carries the risk of a malpractice claim or a regulatory inquiry. Missed deadlines, drafting errors, conflicts of interest, or a client who simply disagrees with the outcome — any of these can lead to a claim, regardless of whether negligence actually occurred. Defense costs alone can be significant, even for claims that are ultimately dismissed.

Lawyers Professional Liability (LPL) insurance covers the cost of defending against malpractice allegations and pays damages if liability is established. Most state bars strongly encourage it, and many clients — particularly institutional ones — require proof of coverage before engaging outside counsel. For solo practitioners and small firms especially, a single uninsured claim can threaten the viability of the practice.

What Are Limits and Deductibles?

Your limit is the maximum your insurer will pay on covered claims. LPL policies typically have two limits: a per-claim limit, which caps what the insurer pays on any single claim, and an aggregate limit, which caps total payments across all claims in a policy period. Choosing the right limits depends on your practice areas, client profile, and the size of matters you handle — a firm doing high-value M&A work faces different exposure than one focused on residential real estate.

A deductible is the amount your firm pays out of pocket before coverage applies. Higher deductibles lower your premium, but they also mean more direct cost when a claim arises. For most small firms and solo practitioners, keeping the deductible manageable is important — defense costs on even a straightforward malpractice allegation can add up quickly.

Why Do LPL Prices Vary?

Insurance pricing depends on a combination of factors specific to your firm. Firm size, revenue, practice area mix, claims history, and state of practice all influence how an underwriter evaluates your risk. Firms practicing in higher-risk areas like plaintiff-side litigation or securities law will generally see higher premiums than those focused on general commercial litigation.

Market conditions play a role too. When malpractice loss trends are favorable, insurers compete more aggressively and premiums compress. When claim frequency or severity rises, pricing firms up across the board. The ranges shown here reflect what firms with similar profiles have actually paid, giving you a realistic benchmark.

The best way to get a precise number is to run a quote. Embroker’s application takes minutes, and you’ll get a bindable price — not an estimate — tailored to your firm’s actual profile.
