This trial that you're talking about, is it the same trial she just went through in the earlier chapters or is it one coming up in the future? I mean, if it's the former, I don't really see the benefit of voiding out her marriage back then. I mean what's there to gamble since wouldn't that take away her title of Duchess/Head of the family name, (because then she would no longer be married to the name) leaving it open for those greedy relatives to come claim that title? And I thought the whole point of that trial was to show she could lead the family and properly manage the family wealth even though she's still young. If it's the latter though, I could understand if this situation arose where such a thing was more beneficial to her and the kids.
