Short answer. Possibly yes. Acceptance of an inheritance is normally irrevocable, but the Civil Code carves out an exception: you can challenge it if the acceptance was obtained through fraud, duress, undue influence, or any other cause that vitiates consent. The burden of proving the pressure falls on you.
What the law says
The acceptance or repudiation of an inheritance, once made, is irrevocable, and cannot be impugned, except when it was made through any of the causes that vitiate consent, or when an unknown will appears.

The general rule: acceptance cannot be undone
Article 1056 of the Civil Code establishes that once you accept or repudiate an inheritance, that decision is irrevocable. This rule exists to give finality to estate settlements — heirs cannot simply change their minds months later when circumstances shift or when they realize the inheritance came with debts they did not expect. An estate that re-opens every time an heir regrets a decision would never settle. So the starting point is firmly against you: acceptance sticks.
The exception: vitiated consent
The Civil Code allows you to challenge an acceptance when it was made through any of the causes that vitiate consent. Those causes are recognized elsewhere in the Civil Code and include fraud, intimidation, violence, undue influence, and mistake. If someone threatened you, deceived you about the true state of the estate, or exerted pressure that overpowered your free judgment, the acceptance you gave was not genuinely free — and the law allows you to impugn it. The same window opens if an unknown will later surfaces that would have changed your decision.
What you need to prove
Claiming vitiated consent requires more than saying you felt pressured. You will need to show that the pressure was serious enough to overcome a reasonable person's will — general family pressure or emotional persuasion typically falls short. The kind of duress that succeeds is a threatened harm that left you no real choice. Fraud must be shown to have been the reason you accepted; if you would have accepted anyway, the fraud did not vitiate your consent. Document everything you can: messages, witnesses, the timing of the acceptance relative to the pressure applied, and any statements the other party made that misrepresented the estate's value or liabilities.
Act promptly — delay can bar your challenge
The right to challenge a vitiated acceptance is not open-ended. The Civil Code's general rules on annulment of voidable acts set time limits within which an action must be brought, and those limits run from the time the defect of consent ceased — meaning from when the pressure lifted or when you discovered the fraud. Waiting too long can extinguish your right entirely. If you believe your acceptance was obtained under duress or fraud, the time to seek legal advice is now, not after months have passed. The estate may be distributed and third-party rights may have vested in the interim, complicating recovery further.
