A collection of equitable and legal principles that bar a party from denying the truth of a representation or the existence of a legal relationship when another party has reasonably relied on that representation or relationship to its detriment.
Ethan Evans was acquitted of robbing one victim when identity was the sole disputed issue at trial. The state later charged him with robbing a second victim during the same incident. The court dismissed the new prosecution because the prior acquittal had already determined that Evans was not the perpetrator.
Edgewater Capital employed Eric Espinoza as a regional manager who regularly negotiated service terms with clients. Eric promised a customer priority restoration rates that exceeded his actual authority. The firm was bound by inherent agency power arising from the employment relationship itself rather than any manifestation that could support estoppel.

Emerald Enterprises recorded a declaration imposing parking and access servitudes on its core parcel to implement a coordinated retail development. It later conveyed an outparcel to Erika Echevarria whose deed referenced participation in the unified project. Erika obtained implied rights to the servitudes because the recorded plan and deed reference estopped the developer from denying her benefit.
Esme Ellington conveyed a parcel by warranty deed to Elijah Edwards even though she did not yet hold full title. She later inherited the missing interest from her relative. The after-acquired title passed automatically to Elijah because estoppel by deed prevented Esme from denying she had conveyed good title at the time of the deed.
Eclipse Manufacturing financed and directed every strategic decision in a supplier's earlier suit challenging a fee methodology. When Eclipse later sued the same defendant over identical fees, the court held Eclipse bound by the prior determination because its control over the first action created the necessary privity for collateral estoppel.
Eva Espinosa and her co-owner jointly held a strip of land. Only Eva signed a recorded agreement granting a permanent no-build zone to a neighboring restaurant. The attempt did not bind the non-signing owner but created rights enforceable against Eva and supplied the factual predicate for later creation of a servitude by estoppel against the remaining owner.
Collateral estoppel prevents relitigation of an issue actually and necessarily decided in a prior action between the same parties or their privies. Claim preclusion bars an entire claim that was or could have been raised in the earlier suit. The Supreme Court cases emphasize that collateral estoppel applies only when the issue was distinctly put in issue and directly determined.
When a grantor conveys an interest by warranty deed that the grantor does not then own, any later-acquired title passes automatically to the grantee. The grantor is estopped from denying the earlier conveyance. This rule protects marketability and prevents the grantor from retaining title obtained after purporting to convey it.
An attempt by fewer than all owners to create a servitude does not bind non-joining owners but creates rights enforceable against those who joined. The attempt may later support creation of a servitude by estoppel if the non-joining owners' conduct induces reasonable reliance. Silence during negotiations combined with joint marketing materials can support such estoppel.
Inherent agency power arises solely from the agency relationship and protects third parties harmed by or dealing with the agent. It does not depend on the principal's manifestations that would support apparent authority or estoppel. The Restatement treats it as a separate source of power to fill gaps left by authority and estoppel doctrines.
