South Carolina is not an insurer-friendly state when an insurer acts unreasonably. The statutory framework is contained in SC Code Title 38, Chapter 59, enacted in 1987 and refined through subsequent case law.
SC Code § 38-59-20 — "Improper claim practices" — lists five specific acts that constitute violations: knowingly misrepresenting policy provisions, failing to acknowledge pertinent communications with reasonable promptness, failing to adopt and implement reasonable standards for prompt investigation and settlement, not attempting in good faith to effect prompt fair equitable settlement of claims in which liability has become reasonably clear, and compelling policyholders to institute litigation to recover amounts due under policies by offering substantially less than the amounts ultimately recovered.
SC Code § 38-59-40 — "Liability for attorneys' fees where insurer has refused to pay claim" — is the enforcement teeth. When an insurer refuses to pay a covered claim within 90 days of demand, and a trial judge finds the refusal was without reasonable cause or in bad faith, the insurer is liable for the policyholder's attorneys' fees up to one-third of the judgment. The insurer cannot compel you to sue for the policy amount and then stick you with the legal bill.
Beyond the statutory framework, SC common law recognizes a tort cause of action for bad faith refusal to pay first-party insurance benefits. Available damages can include the policy benefits, consequential damages, attorneys' fees under § 38-59-40, and in egregious cases, punitive damages. The statute of limitations is three years from the bad-faith act.
