7th house belongs to Venus, so it will give mixed results. The native will have rise in luck after marriage and native will be involved in religious works. The good result of the house will depend upon position of Moon. The native will never be a debtor and will have good children. And if the sun is also in 1st house the native will be a good astrologer and lover of comforts. However if Jupiter is malefic in 7th house and Saturn is in the 9th the native will become a thief. If Mercury is in the 9th then his married life will be full of probelms. If Jupiter is malefic native will never get support from brothers and will be deprived of favours from the government. Jupiter in 7th house causes differences with the father. If so one should never donate clothes to anyone, otherwise one will certainly get reduced to extreme poverty.
