Re: As u might know…
The idea behind the annulment of the marriage is basically saying the marriage is null and void. Marriage was not consummated. That the guy’s side of the family lied, misrepresented themselves or something else along those lines. Which they did…they made themselves out to be financially stable when in fact they’re not if they need to beg and demand money for the guy’s visa and funiture for his parents’ home. How would that even apply if the rukhsati had happened? If the rukhsati happened, it would make the marriage look more solid which would mean an annulment cannot apply.
As far as the methods of divorce…well…if you cannot get him to comply then go for the 1 year route. Your sister will not be getting married within three months of divorce.
The last part…I don’t think that’s true. Verbal talaaq is valid and so is written. A written talaaq has been considered sufficient for divorce. Her divorce decree would be her written talaaq so why isn’t it valid? What Mufti/Sheikh needs to confirm that?
