Sun in the 7th house centers your identity on partnership, so you often discover who you are through relationship with a strong other.
The short version
With the Sun in your 7th house, partnership carries real weight in shaping your identity. The partner is often strong, prominent, or dominant, and sometimes seems to outshine you. There can be ego dynamics in marriage to work through. The gift is a capacity for collaboration that builds visible joint accomplishment.
What the 7th house is about
The 7th house governs partnership: marriage, committed relationships, and business partners. It also rules contracts and your one-to-one dealings with others. It sits directly opposite the 1st house of self, so it is where you meet the other. See The 12 Houses.
Sun in the 7th house
The Sun is Surya, the planet of identity and ego, and the 7th house is the house of partnership and the significant other. Placing the self in the house of the other creates an interesting tension. You tend to find your sense of self through relationship, and partnership becomes central to your identity, but the spotlight that the Sun wants has to be shared, which is not always easy.
The partner is often strong, accomplished, prominent, or dominant, and there can be a sense that they outshine you, or that your identity gets discovered through them. Ego dynamics, competition, or power struggles in marriage are a common theme to work through. Classically this can be a more challenging placement for marriage for exactly this reason. The gift is a capacity for genuine collaboration and partnerships that build visible joint accomplishment. The growth edge is ego clashes with the partner and tying your self-worth to the relationship.
From the 7th house, the Sun casts its aspect onto your 1st house of self, so your partnerships directly shape your identity and how you show up in the world.
How it shifts by sign and dignity
The sign strongly colors the result. The Sun is exalted in Aries, which can intensify the ego dynamics in partnership, debilitated in Libra, which is significant because Libra is the natural sign of the 7th house, so a Libra 7th is the Sun's debilitation and asks for extra care with self-assertion in relationship, and at home in Leo, which gives a proud, warm approach to partnership.
The Sun never goes retrograde and is never combust, since it is the Sun that combusts other planets that come too close (see Combust Planets). Weigh the whole picture with Planetary Strength.
When it shows up
Partnership themes often come forward during a Sun Mahadasha, the 6-year period when relationships and the public other are highlighted, or when the Sun is active by transit over the 7th. These periods often bring significant partnerships and lessons about sharing the spotlight.
What to do with it
Choose partnership as a place to grow rather than compete. Let your partner shine alongside you, since collaboration, not rivalry, is where this placement succeeds. Keep a secure sense of self so your worth does not rest on the relationship or on outshining your partner. Built well, a partnership of two strong people can produce visible, shared accomplishment that neither could reach alone.
