Unlimited liability means that an agency could be held responsible for all losses, damages, or costs arising from a contract—without any cap or maximum limit. Unlike limited liability, which restricts financial exposure to a set amount, unlimited liability exposes the agency's assets (and sometimes its owners' personal assets) to potentially catastrophic claims.
These clauses are often found in indemnity, warranty, or damages sections of client contracts and can be triggered by breaches, negligence, or even third-party claims.
