Deductible vs Self-Insured Retention
Both deductibles and self-insured retentions (SIRs) represent the amount a law firm must pay out of pocket before insurance coverage kicks in. However, they function differently in terms of when the insurer begins participating in a claim and who controls the defense. These structural differences can significantly affect a firm's cash flow and claims experience.
Deductible
Advantages
- The insurer handles the claim from the start, including defense, and recoups the deductible later
- The firm benefits from the carrier's claims management expertise immediately
- Deductible amounts are typically lower and more predictable for budgeting purposes
- Defense costs paid by the insurer usually count toward satisfying the deductible
Disadvantages
- Less control over the defense strategy since the carrier manages the claim
- The insurer may push toward settlement even when the firm prefers to fight the claim
Best for: Small to mid-size firms that want the insurer to take the lead on claims management from day one and prefer predictable, lower out-of-pocket exposure.
Self-Insured Retention (SIR)
Advantages
- The firm retains full control over defense strategy until the SIR is exhausted
- Ability to select defense counsel and manage the claim on your own terms initially
- Can result in lower premiums compared to a traditional deductible at the same dollar amount
Disadvantages
- The firm must fund the entire SIR amount before the insurer pays anything, creating cash flow pressure
- Requires internal resources or outside counsel to manage early-stage claims
- If the SIR is not satisfied, the insurer may have no obligation to participate in the claim at all
Best for: Larger firms with in-house risk management capabilities and sufficient cash reserves to fund defense costs upfront while maintaining control over claim strategy.
Verdict
Most law firms are better served by a traditional deductible because it ensures the insurer is involved from the first dollar of defense costs. SIRs can save money on premiums but require financial readiness and claims management sophistication that smaller firms typically lack. If your firm has the resources and wants to control its own defense, an SIR can be a strategic choice.
