Short answer. Generally no. Under the Civil Code's rule on estoppel, an admission or representation you made is rendered conclusive upon you and cannot be denied or disproved as against the person who relied on it. Once another has acted on what you said, the law holds you to it and closes the door to a later denial.

What estoppel does

The rule is compact but powerful. Through estoppel an admission or representation is rendered conclusive upon the person making it, and cannot be denied or disproved as against the person relying thereon. In plain terms, if you tell someone a certain state of things is true, and they act on your word, you are not free to turn around later and say it was not true — at least not against that person. The law shuts your mouth on the point. Estoppel is not about punishing you; it is about protecting the person who trusted your statement and changed their position because of it.

Why the law binds you to your word

The principle rests on fairness and good faith. It would be unjust to let a person induce another to act on a representation and then, when it suits them, disown that very representation to the other's harm. Commerce and everyday dealings depend on being able to rely on what people assert; if every admission could be freely retracted, trust would collapse. Estoppel supplies the discipline: having led someone to rely, you bear the consequences of your own statement. The focus is squarely on the relationship between the maker and the one who relied — the admission becomes conclusive as against that person, not necessarily as against the whole world.

Reliance is the hinge

Estoppel does not spring from a statement alone; it turns on reliance. The provision protects the person relying thereon, which means the other side must actually have relied on your admission or representation, and typically to their detriment or by changing their position. If no one relied — the statement was ignored, or the other party knew the truth independently — the foundation for holding you conclusively bound is weaker. This is why estoppel is fact-sensitive: what exactly you represented, whether it was reasonable for the other to rely, and whether they in fact acted on it are the questions that decide whether the door to denial is truly closed.

Before you try to take it back

If you are tempted to disown something you earlier said, assume the law may hold you to it and think carefully. Look at what precisely you represented, to whom, and what they did in response. Sometimes a statement was qualified, or the other party did not genuinely rely, or the matter falls outside estoppel's reach — but these are narrow openings, not general escapes. Because being estopped can be decisive in a dispute, and because the analysis depends heavily on the specific words and conduct involved, it is worth having the situation assessed by a lawyer before you act on a plan to contradict your earlier admission.
