Succedent house · shared money, intimacy, deep trust
When the other person's planet falls in your 8th house, it shapes how you handle those matters together. You are the house owner; the other person brings the planet. Their presence can make private subjects feel harder to keep at a distance, whether you are discussing a bill, sharing a confidence or facing a change. The contact can feel close and absorbing, but it also brings questions of boundaries and what each person owes or expects. Its expression depends on the planet involved and how both people respond.

The question this overlay asks
How does their planet affect shared money, intimacy and trust when it lands here?
Their planets in your 8th house
A planet of the other person lands in this house of your chart and brings its own errand. The ten planets, from the Sun to Pluto:
Their Sun in your 8th house
The Sun in your 8th house brings the other person's pride and need to be taken seriously into shared money and private decisions. They want their plans to count, and feel warmer when you recognize their contribution.
Their Moon in your 8th house
The other person wants to feel safe enough to share private worries and daily needs with you. Their Moon in your 8th house draws care into intimate matters, though they may go quiet or seek reassurance when trust feels uncertain.
Their Mercury in your 8th house
A question about a shared bill or private promise can make you notice how carefully the other person listens. Mercury in your 8th house prompts them to explain, ask follow-up questions and talk problems through, though misunderstandings can linger.
Their Venus in your 8th house
In your 8th house, Venus brings the other person's affection into intimacy and shared resources. They show care with touch, thoughtful gifts or a kind word, and want to feel chosen; keeping things pleasant can leave hard money questions unspoken.
Their Mars in your 8th house
Trust gets more direct when Mars lands in your 8th house. The other person goes after what they want in private matters, brings desire and physical boldness, and can turn a disagreement about money or closeness into a contest.
Their Jupiter in your 8th house
You notice the other person offering more than you asked when shared costs or private worries come up. Jupiter in your 8th house brings generosity and hope to what you share, though their broad promises can blur limits or leave debts unclear.
Their Saturn in your 8th house

Their Neptune in your 8th house

Their Pluto in your 8th house
In your 8th house, Pluto makes the other person press for deep closeness and full honesty. They feel private matters intensely and may hold back or seek control after a breach of trust; that pressure can expose what needs to change.
