A misrepresentation by one party makes the contract voidable if the other party so decides.
I note that the original marriage is voidable, not void: unless the parties go to court to have it annulled, the original marriage remains valid.
In law, an agreement reached under duress is voidable and cannot be enforced.
Offending contracts would not be void, unenforceable or voidable.
Before that date a decree of nullity did not distinguish between a void and a voidable marriage.
This is an example of a voidable marriage.
It does not turn on whether the marriage is voidable or void; one will not get the interim certificate without having a divorce.
However, they further recommended that a voidable marriage should be treated as valid until the decree absolute was made.
That is a case in which a petition for nullity of a voidable marriage may be presented.
