Common questions
Frequently Asked
5
How does authority by estoppel arise?+
It arises when a principal's manifestations to a third party reasonably lead that party to believe an agent has authority to act. The third party's reasonable belief, created by the principal's conduct, binds the principal even without actual authority.
Supporting sources
When does authority by estoppel terminate?+
It terminates when the third party receives notice that the principal no longer consents to the agent acting on its behalf. An internal revocation alone does not end the appearance of authority until communicated or otherwise made known to the third party.
Supporting sources
Does authority by estoppel require actual authority?+
No. It exists independently when the principal's manifestations create a reasonable belief in the third party, regardless of whether the principal privately authorized the specific act.
Supporting sources
Can authority by estoppel bind a partnership for a partner's acts?+
Yes. A partnership is liable for a partner's wrongful acts or misapplication of funds when the partner acts with apparent authority in the ordinary course of business.
Supporting sources
Does a lawyer's authority by estoppel allow enforcement of a settlement?+
Yes. A lawyer of record is presumed to have apparent authority to settle litigation. The opposing party may rely on that appearance absent notice of limitations, and the settlement binds the client.
