Who can challenge a voidable marriage?

A voidable marriage is one that is valid until it is annulled, meaning that it has legal effect unless one of the parties chooses to challenge it. The critical aspect here is that the parties involved in the marriage have specific grounds upon which they can challenge the validity of the marriage, such as lack of consent, fraud, or other similar reasons. Consequently, only individuals who are parties to the marriage have the standing to contest its validity.

The state generally does not intervene unless there are concerns about public interest or legal implications that arise from the marriage. Parents or other relatives also do not have the legal authority to challenge a marriage on behalf of their children or family members unless they themselves are party to the marriage or have legally recognized authority.

Therefore, the correct understanding is that only the parties involved in a voidable marriage can challenge it, making this the appropriate choice.
