What is the ruling if a woman states she is already married, but then retracts this statement after the marriage contract has been concluded?

Primary text

If a woman claims to be married and then retracts that claim after the contract is concluded, the retraction is not accepted. This retraction is treated as the invalidation of a binding contract established by her own declaration, similar to when someone admits a wife's marital status to another person and subsequently retracts that admission.
