Who's Liable When an Agent Signs the Contract?

When an agent signs a contract, determining liability can be complex. An agent negotiates terms and commits its principal to a purchase order, but the agent itself is not a legal entity and cannot bear liability. Liability in such cases typically falls back to a human or an entity that can be held accountable. The real question is where liability ultimately lands along the chain of responsibility from principal to agent to sub-agent to third-party tools.

Initially, one might assume an agent's action is akin to an employee's, making the principal vicariously liable. However, this simplistic approach fails as delegation becomes more complex. For instance, if a principal authorizes an agent to negotiate contracts up to a certain spending limit, and that agent delegates supplier research to a sub-agent which then calls a third-party pricing tool, the liability becomes challenging to ascertain.

The principal might be technically liable for deploying the agent, but this does not address the underlying issues of who was authorized, informed, and had the ability to prevent a bad outcome.

Verifiable credentials play a crucial role in this scenario. These credentials provide a specific, expiring token that proves the agent's authority at the exact moment of contract signing. Without this evidence, determining liability becomes difficult. A liability framework must not only track who initiated the action but also verify who had the authority, the information, and a checkpoint to prevent bad outcomes.

Policies indicating agents do not sign contracts above a certain amount without human approval are essential but must be substantiated with verifiable evidence.

In practice, this means operators must maintain detailed logs of approvals, credentials, and timestamps to prove whether those responsible for authorizing the action were indeed in place at the time of signing. This approach helps distinguish between governance failures and ordinary business risks. For instance, if a contract is signed after a credential should have expired, it indicates a governance failure with a clear accountable gap.

Conversely, if a contract is signed within valid authority and turns out to be a poor commercial decision, it reflects typical business risk.

Regulators and counterparties increasingly seek clarity on whether a contract's liability stems from a governance failure or an ordinary risk. Without verifiable credentials and detailed authorization logs, proving the exact moment of liability attribution becomes nearly impossible. Thus, building this discipline into contracting processes is crucial.

Operators who prioritize the development of robust authorization and attribution infrastructure before facing potential disputes are better positioned to handle liability issues effectively.
