Again you are asking me Question with Half information. marriage works with two people and both charts are important, that is the reason why horoscope matching is insisted. Even if one horoscope is weak the can support it. The dosha that come will decide the problems.
In the Ashtkoot Guna milan , there are multiple dosha that can create problems,
Like Mangal dosha – can create problems of anger, aggression, death
Nadi Dosha – Progeny Related problems
Yoni – Sexual incompatibility
Gana – Temperament problems
Bhakoot – Love and relationship, health, finance
Therefore if you have both charts data, provide information.
