过户的时候HOA认同，应该没有你任何责任了。

Estoppel is a ... legal doctrines in common law legal systems whereby a person is prevented from making assertions that are contradictory to his or her prior position on certain matters before the court—the person is said to be "estopped".

HOA以前的assertion=> 允许过户，没有违规，和现在的assertion=》违规需要改正，是矛盾的。法律上HOA应该被estopped。
