Quasi Estoppel Law & Legal Definition


Quasi estoppel is an equitable doctrine that prevents a person from denying an act or assertion if such denial is deemed to bring harm to another who reasonably relied on the act or assertion. The doctrine of quasi-estoppel prevents one party from taking a position inconsistent with a position that was previously advocated, regardless of whether the party to be estopped intended to misrepresent or conceal facts.

Elements of the doctrine of quasi-estoppel are met when a litigant :

1.has knowledge of the facts ;

2.takes a position inconsistent with his/her former position;

The defense of quasi estoppel also applies when it is unconscionable to allow a person to maintain a position inconsistent with his/her earlier position or from which s/he accepted a benefit. Quasi-estoppel does not require a showing of misrepresentation or detrimental reliance.[Yturria v. Kerr-Mcgee Oil & Gas Onshore, LLC, 291 Fed. Appx. 626, 635 (5th Cir. Tex. 2008)]
