Nevada, the elements to prove equitable estoppels or promissory estoppels are:
1.Party to be estopped
must be apprised of true facts;
2.The party to be estopped
must have intended that his conduct shall be acted upon or must so act that the
party asserting estoppels has the right to believe it was so intended;
3.The party asserting estoppel
must be ignorant of the true facts; and
4.The party asserting estoppels relied on
the conduct of the other party, to his detriment.
Estoppel operates to prevent a party from asserting
legal rights that, in equity and good conscience, they should not be allowed to
assert because of their own conduct.Silence can raise estoppel.NGA No. 2 Ltd. Liability Co. v. Rains, 13 Nev. 1151, 946 P.2d
