Dear Madam,
498a case can be used by a women on the same family multiple times, there is no limit in number as such. However the case itself takes a long time to resolve (most of the cases with monetary settlements) hence chances of filing the case for the second time is too low. At the same times most of the 498 cases ended up with financial settlements for wives… families of men won’t like to do the positive compromise (reunion) as the women feels highly empowered having won the case in some way (Husbands family did positive compromise).
