As I mentioned in this post, my personal view is that a woman should be able to obtain maintenance in case of break-up of a bigamous marriage if she is otherwise unable to support herself.

Yes, I do get your point that a woman who has been in a relationship with a man, not knowing that he is already married [thus rendering her marriage to him bigamous] would be penalised for no fault of hers. And my sympathies are with the woman in such a relationship.

Yes, the second wife is certainly entitled to respect and dignity. I would think, though, that this would be more of a social, rather than legal issue.

This is a tricky issue, as some commenters here have said, and I think a lot would depend on the discretion of the judge concerned.

Thanks for commenting !
