Defense Inside the Limit
A policy structure where defense costs reduce the available policy limit, common in professional liability and D&O policies.
What It Is
Defense Inside the Limit (also called 'eroding limits,' 'burning limits,' or 'defense within limits') is a policy structure where legal defense costs—attorneys' fees, expert witnesses, court costs, and other litigation expenses—are paid from and reduce the policy's coverage limit. Every dollar spent on defense reduces the dollars available for settlement or judgment.
This structure is standard in professional liability, D&O, EPLI, and cyber insurance policies. It contrasts with defense outside the limit (standard in CGL policies), where defense costs are paid in addition to the policy limit and do not erode the available coverage.
Defense inside the limit creates a tension between aggressively defending a claim (which consumes limit) and settling early (which preserves limit). In complex litigation, defense costs can consume 30-50% or more of the policy limit, leaving significantly less for indemnity payments. Some policies address this by offering a 'defense cost' sublimit or a separate defense cost allowance in addition to the indemnity limit.
Why It Matters for Brokers
Brokers must ensure clients understand that their professional liability limit is not fully available for settlements—defense costs will consume a significant portion. A $1M E&O policy that spends $400,000 in defense has only $600,000 remaining for a settlement or judgment. This is one of the strongest arguments for higher professional liability limits, as the effective indemnity coverage is always less than the stated limit.
Real-World Example
An architectural firm with $2M E&O (defense inside the limit) faces a $3M design defect claim. Defense costs through 3 years of litigation: $850,000. Remaining limit: $1,150,000. The case settles for $1.4M. The policy pays only $1,150,000 (remaining after defense costs), and the firm pays $250,000 out of pocket. If the firm had purchased $3M in coverage (approximately $4,200 more annually), the full defense costs and settlement would have been covered. The $4,200/year savings over 3 years ($12,600) cost the firm $250,000.
Common Mistakes
- 1Not explaining to clients that defense costs reduce their policy limit, leading to shock when a significant portion of the limit is consumed by legal fees before any settlement.
- 2Setting professional liability limits based solely on indemnity needs without accounting for the defense costs that will erode the limit.
- 3Not exploring policies that offer defense outside the limit or a separate defense cost allowance, which may be available at competitive premiums.
How brokerageaudit.com Handles This
brokerageaudit.com's Policy Checker identifies whether each professional liability policy provides defense inside or outside the limit and displays this prominently. The system estimates typical defense costs by claim type and calculates the effective available indemnity after defense erosion. The platform recommends minimum limits that account for both defense costs and indemnity needs.
