How does a counterparty know the agent is authorized?

Through the Agent Charter: a Power of Attorney and Agent Mandate stating the agent's scope and limits, plus a machine-readable mandate. High-value or out-of-scope actions can require human approval.

Can an AI agent sign contracts?

Q: Can an AI agent sign a contract?

Not in its own name — an AI agent is not a legal person, so it has no capacity to contract for itself. But it can sign on behalf of a company as an authorized delegate, when a power of attorney and a mandate grant that authority and the counterparty can verify it.

Q: Is a contract signed by an AI agent enforceable?

It is enforceable against the company when the agent acted within authority the company actually granted (and the counterparty reasonably relied on it). That's why a documented mandate plus power of attorney matters — it establishes and proves the authority.

Not in its own name — but that's not the end of the story. With the right authority in place, an agent can sign on behalf of a company, and the deal binds. Here's the legal basis and how to set it up properly.

Direct answer: An AI agent cannot sign in its own name — it isn't a legal person and has no capacity to contract for itself. But it can sign as the authorized delegate of a company, when a power of attorney and a mandate grant that authority and the counterparty can verify it. The contract then binds the company, not the agent.

Why not in its own name

Contracting requires legal capacity, which only natural persons and recognized legal entities have. An autonomous agent is software — it can't hold rights or obligations, so "the agent signed" has no standalone legal meaning. If it acts without an entity behind it, any obligation it appears to create falls back on a human (you).

How it can sign — as a delegate

The same way an employee or officer signs for a company: through delegated authority. Put a company between the agent and the world, and grant the agent a defined power to act for it. Three documents make that real and provable:

Power of Attorney — authorizes the agent to act and sign on the company's behalf, so a counterparty can rely on it.
Agent Mandate — the precise scope: what it may sign, spending and risk limits, what's excluded, and the kill-switch.
Machine-readable mandate — the agent reads it at runtime to stay inside its authority.

Signed this way, the agreement binds the company — the same liability containment you want everywhere else.

Proving authority to the other side

Enforceability turns on authority: a deal binds the company when the agent acted within authority the company actually granted, and the counterparty reasonably relied on it. A clean, citable document set (POA + mandate) is exactly what establishes and proves that — instead of "trust me, it's my bot". For the actions that matter most, keep human approval in the loop.

Practical note: most agent "signing" today is e-signature or on-chain transactions. The legal substance is the same — the question is always whose authority the agent is exercising, and whether that can be shown.
