The 7th house is the partnership zone of your birth chart. It describes one-to-one bonds: marriage and long-term love, business partners, best friends, even rivals, and the qualities you go looking for in the people you commit to.
What the 7th house rules
Every serious two-person bond lives here: spouses and long-term partners first, then business partners, contracts, and the handful of friendships that function like family. Traditional astrology also files "open rivals" under the 7th, which sounds odd until you notice that a real rivalry is a committed one-to-one relationship too.
The 7th sits directly opposite the 1st house, and its cusp is called the descendant. The 1st is you; the 7th is who you pair with. That axis is why the people we commit to so often carry qualities we underplay in ourselves: the chart literally puts them across from us.
Planets in the 7th house
Planets here put their agenda into your partnerships. Three worked examples:
Venus in the 7th treats partnership as a native language. Relationships tend to arrive without much hunting, being partnered feels natural, and being single tends to feel louder than it does for other people.
Saturn in the 7th takes commitment seriously and sometimes late. Standards run high and can read as walls, right up until someone meets them. The bonds that do form are built like infrastructure, and they last.
Mars in the 7th attracts spark and friction in the same package. The right partner is someone who can argue well and repair better; the wrong one mistakes the heat for the whole relationship.
The sign on your 7th house cusp
The sign crossing the descendant flavors what partnership needs to look like for you. An Aries descendant tends to want a partner with their own engine and no fear of directness. A Cancer descendant partners toward warmth, loyalty, and someone who makes home feel safe. A Capricorn descendant respects competence and follow-through more than grand declarations.
The planet that rules your descendant sign, and where it sits in your chart, adds the next layer: it shows which part of life your partnerships keep getting tangled up with.
An empty 7th house is fine
The most-asked question about this house has the gentlest answer. There are about ten planets and twelve houses, so several houses sit empty in every chart ever cast. An empty 7th says nothing against love, marriage, or partnership.
It usually just means partnership themes route through other parts of your chart. Read the sign on the cusp and its ruling planet, and the 7th house story shows up there instead.

Which house is marriage in astrology?
The 7th house. It governs marriage and every committed one-to-one bond, including long-term partners you never legally marry and business partnerships you formalize with a signature.
What does an empty 7th house mean?
Nothing ominous. With around ten planets and twelve houses, every chart has empty houses. An empty 7th simply means you read the sign on its cusp and that sign’s ruling planet to understand how you partner, rather than a planet sitting in the house itself.
Who is my 7th house ruler?
Find the sign on your 7th house cusp, then the planet that rules that sign. A Libra cusp makes Venus your partnership ruler; an Aries cusp makes it Mars. Wherever that ruling planet sits in your chart is where your partnership story tends to play out.
Is the 7th house only about romance?
No. It covers every bond where two people formally team up: marriages, business partners, long-standing creative duos, best friendships, and even declared rivals. Romance is simply its most famous tenant.
