Mangal Dosha and Trouble in Married Life
Mangal dosha is present when Mars occupies the 1st, 2nd, 4th, 7th, 8th, or 12th counted from the lagna, from the Moon, or from Venus. The marriage heat is strongest when the count that qualifies is the 7th itself.

Where the heat lands
Mars in the 7th sits in the spouse's house, so argument, haste, and a competitive tone in the marriage are the direct reading. Mars in the 1st puts that heat in the native's body and temper. Mars in the 8th puts it in rupture, secrecy, and shared resources. Mars in the 4th disturbs domestic peace, because the 4th is the home. Mars in the 2nd disturbs family speech and the household purse. Mars in the 12th puts heat into the bedroom, expenses, or a marriage lived at a distance. One chart can be Manglik from the Moon and quiet from the lagna. Say which count you used.
Dignity and Jupiter change the dosage
Mars in its own signs, Mesha or Vrishchika, or exalted in Makara, is a Manglik Mars with dignity, and matchers treat that dignity as a softener. Jupiter aspecting Mars, by the 5th, 7th, or 9th glance, is the other classical softener. A second chart that also carries Mangal dosha is the comparison many North Indian matchers rely on, so the dosha is not judged from one horoscope alone. Mars debilitated in Karka is a weaker Mars that still occupies whatever Manglik house it occupies. Debility does not erase the count.
The seven-year Mars period
Mars mahadasha lasts 7 years. Trouble that belongs to Mangal dosha is timed when Mars, or the 7th lord Mars rules, runs as mahadasha or antardasha. A Mars in the 4th can disturb the home for years without ending the marriage, especially if the 7th lord and Venus are strong in Navamsa. The dosha is a matching and temperament factor. It is not a prediction that the spouse will be harmed, and it is not a reason to delay a wedding by a fixed number of years the chart does not state.
Frequently asked questions
Is Mars in the 7th the only Mangal dosha that touches marriage?
It is the placement inside the spouse house. Mars in the 1st, 2nd, 4th, 8th, or 12th still qualifies under the common count, and it touches marriage through temper, family, home, rupture, or distance.
Does exaltation cancel the dosha?
Mars exalted in Makara, or in its own sign, is widely treated as a softer Manglik condition. The Mars is still there. Matchers read the dignity, they do not pretend the house is empty.
Can one chart decide the marriage?
The dosha is compared across both charts, along with the 7th lords and both Navamsas. A single Manglik count is the start of the matching, not the whole of it.
