Estoppel in Pais Law and Legal Definition

An estoppel in pais refers to an estoppel which does not spring from a record, or a deed. It is made to appear to the jury by competent evidence. By an estoppel in pais a party is prevented by his/or her own conduct from obtaining the enforcement of a right which would operate to the detriment of another who justifiably relied on such conduct. Courts adopt estoppel in pais when a contradictory stance stands unfair to another person who relied on the original position.
