estoppel

**estoppel**

Estoppel is a legal principle that prevents a person from arguing something contrary to a claim they previously made or accepted as true, especially when others have relied on that claim. It ensures fairness by stopping individuals from adopting inconsistent positions in legal proceedings. Common types of estoppel include promissory estoppel, equitable estoppel, and collateral estoppel. This concept is frequently referenced in contract law, property disputes, and litigation to maintain integrity and prevent injustice.
