What does the term "irrevocable" mean in a legal context?

In a legal context, the term "irrevocable" signifies that something cannot be recalled, revoked, or altered once it has been established. This is particularly relevant in contracts or agreements, where an irrevocable decision or clause indicates that the parties involved cannot change their minds or withdraw from the commitment without significant consequences.

For instance, an irrevocable power of attorney allows the appointed individual to act on another's behalf without the possibility of revocation, reflecting a high level of trust and commitment. This concept is critical in scenarios such as legal agreements, wills, and trusts, where certainty and permanence are necessary.

Other options suggest conditions that imply change or termination. The first option indicates that something can be modified, the second suggests expiration after a certain timeframe, and the fourth hints at mutual agreement for changes. None of these align with the definitive nature of being irrevocable, which emphasizes absolute finality and stability in legal arrangements.
