How the Dosha occurs - Conditions for forming Mangal Dosh
It is generally said that in a chart [Irrespective to male or female native] When Mars is found in any of the houses 1, 4, 7, 8, 12 - Mangal Dosh forms. Some South Indian astrologers also take the 2nd house in addition - while most do not agree to this. [Mars in second can indicate bold or bitter speech, or using slang words etc.]
Mars is a planet of battle, war and fight. He is Tamasic in nature and belongs to the caste of warriors [Kshatriya]. He in general is fond of fights, battles and is given to anger. That is why, very naturally, when he takes over the marital matters, he likes to put quarrel, fight and 'battle' in marriage, which disturb marital happiness. Mars is also he planet of over sex drive, too much boldness, and too fierce in nature - all of them are against a peaceful marriage..
