How a 7th house overlay feels
The seventh house is the house of partnership itself, so overlays here are the ones most associated with marriage and long-term commitment. The planet person tends to feel like a natural partner for the house person — someone they recognize as an equal, an opposite or a match. Because the descendant sits on the horizon, these overlays are strongly affected by birth time, and the house person often feels the other fits the role they want a partner to fill.

House person and planet person
Who feels a 7th house synastry overlay more?
Traditionally the house person sees the planet person in a 7th house overlay as partner material — someone who fills the role of the significant other. The planet person feels drawn into a committed, one-to-one arrangement and may find themselves expected to act as an equal partner; both usually feel it, which is why it is read as the marriage house.
By rising sign
Whose Sun lands in your 7th house
With whole-sign houses your 7th house is the sign 6 steps on from your rising sign. A partner born while the Sun was in that sign has their Sun in your 7th house; their other planets need their own chart.

House type
angular
This house pairs with the 1st across the chart — first impressions and self-presentation — and the two work as one axis. A planet landing here looks straight across at that house, so the two readings belong together rather than separately.
It is an angular house, which sits on an axis of the chart, so it is the group most distorted by an inexact birth time. Its natural ruler is Venus, so a partner's Venus arriving here doubles the theme rather than adding a new one.
Being angular, it shifts first when the birth time is off. How much →
The 7–1 axis
Partnership as an arrangement sits opposite first impressions and self-presentation. A planet in one faces the other across the chart, so an overlay here is always a statement about both — the pairing reads as a formal partnership, which is what tradition considers the point; at the 1st-house end, they change how you come across before you decide to change anything.
