Workers' comp in Oklahoma

Any Oklahoma employer with at least one full-time or part-time employee must carry workers' comp. Family businesses with fewer than five employees, all related by blood or marriage, are exempt.

The agency in charge is the Oklahoma Workers' Compensation Commission. It can tell you whether a specific business needs coverage, and most states let you look up an employer's policy online.

Contractor licensing and insurance

We found no statewide general liability minimum tied to a general contractor license. Oklahoma has no statewide general contractor license. Cities and counties can set their own licensing and insurance rules, so check where the project is.

Indemnity and additional insured clauses

Oklahoma's anti-indemnity statute (Okla. Stat. tit. 15, § 221) voids construction contract clauses that make a contractor indemnify another party for that party's own negligence, even in part. Clauses limited to the contractor's own share of fault generally hold up. The statute also reaches insurance: a contract can't use an additional insured requirement to get coverage for the other party's negligence that the indemnity rule forbids.

What to check on a contractor COI for a Oklahoma project

  1. Workers' comp. Nearly every contractor with employees needs it in Oklahoma. A contractor with a crew and no workers' comp on its COI is a gap. For an out-of-state contractor, confirm Oklahoma is listed on the workers' comp policy.
  2. General liability. Oklahoma doesn't set a statewide floor for a general contractor license, so your project requirements set the bar. Compare each limit on the COI with what the contract asks for.
  3. Additional insured. In Oklahoma, the anti-indemnity statute also limits what an additional insured requirement can do. Ask your broker or attorney which wording holds up, then check that the endorsement on file matches it.
  4. Dates. Every policy should run through the end of the job. A COI only shows coverage on the day it was issued, so check again at each renewal.
