Planets in the seventh house
When a planet is in a house, the planet expresses itself in the corresponding area of the person's life that the house represents. For example, if your Sun is in the Third, you will need to write, teach, chat, barter -- anything having to do with the transfer of information and goods. Regardless of the style of your Sun's expression (its sign), you will not be satisfied unless you communicate.
If you have a planet in the Seventh, you will have to meet that planet's corresponding need in a relationship (romantic, business, open enemy, and so on). In other words, you are dependent on another to fulfill that planet's impulse. So, if you have no planets in the Seventh, it simply means that being in a partnership is not essential to the expression of your planets.
