Jupiter in 7th house.

So, lets see what Jupiter can do in 7th house without any conjunction or aspect from any other planet. 1st lets see what these 2 things represent -

Jupiter is the most benefic planet and it represents all the auspicious things like Knowledge, Wisdom, Law, Guru, Spirituality, Religion, Philosophy, Literature, Elderly People. For a girl, Jupiter also represents Husband.

7th house is house of market place, other people (masses), business partnerships, agreements, marriage, spouse, marital happiness etc.

Basically, if a girl has this position of Jupiter in 7th house, she should feel blessed. Spouse will be of balanced nature. Spouse will work as guidance. He/She will be knowledgeable and full of wisdom. This placement also suggest someone who gains wealth from Business, as Jupiter is wealth and 7th house is Business. This is also a good placement for becoming a lawyer. 

From 7th house, Jupiter's aspect goes to 11th house of gains and network circles. It shows a need to learn about increasing gains.  

Jupiter's next aspect goes to 1st house/Ascendant. 1st house is personality and Jupiter is knowledge and wisdom. So with this aspect, person gets recognition as very wise and knowledgeable in society. 

Jupiter's last aspect goes to 3rd house of Siblings and Self-effort. It shows the need to learn about the right area of self-efforts. 

Hope this helps. Thanks,
