Professional Liability Insurance for Drafters

Also called Errors & Omissions (E&O) insurance — the most critical coverage for any drafter who delivers technical drawings to clients. One mistake in a blueprint can mean a six-figure lawsuit.

What Is Professional Liability?

Professional liability insurance for drafters — also known as Errors & Omissions (E&O) insurance — protects you when a client alleges that your drafting work, drawings, or specifications contained an error, omission, or negligent act that caused them financial loss.

Standard general liability insurance does NOT cover professional errors. You need a separate E&O policy, and most commercial clients will require proof of coverage before signing a contract.

  • Covers legal defense costs even if you're not at fault
  • Pays settlements or judgments against you
  • Protects your business assets from professional claims
  • Required by most commercial contract language
