Yes, same-sex or close relation.
Or something like finding out someone entered into the marriage without the intent to be faithful. Lying about your identity, hiding the existence of a previous marriage (or faking an annulment or divorce), an ongoing sexual relationship with someone else, willful exclusion of procreation, entering into the marriage under duress, would be others.
Catholics are quite picky about validity.
Yeah, I think most of those would be considered valid reasons for dissolving the marriage, assuming the offending person is unrepentant.
Catholics would say that these marriages might "null", meaning that they never actually existed.
Like, if you kidnap someone and force them to marry, then that marriage is never created. You were just mimicking a marriage, like actors in a movie, but nothing actually happened because you didn't fulfill the prerequisites for conducting a valid sacrament.
Sort of the way a non-Christian can perform baptisms that don't actually work.
Oh for sure! Especially in regard to forced "marriages", same sex, or incest.
I also think there is a valid point there with marriages under false pretenses, such as going in with the intent to be unfaithful, false identity, existing previous marriage, etc. But again, I think we would look to see if some of these could be remedied via repentance first, so the marriage could be one in truth, before deeming it invalid.
