Jyotish reads in-laws by treating the 7th house (spouse) as a new ascendant. The spouse’s father is the 9th from the 7th — your 3rd house — and the spouse’s mother is the 4th from the 7th — your 10th house. No single planet “rules” in-laws; the lords of these houses, the 7th lord and Venus (or Jupiter, by tradition, in a woman’s chart) show how the relationship goes.
Houses for in-laws
| Relation | House (counted from the 7th) | House from lagna |
|---|---|---|
| Spouse | 7th | 7th |
| Father-in-law | 9th from the 7th | 3rd |
| Mother-in-law | 4th from the 7th | 10th |
| Spouse’s elder siblings | 11th from the 7th | 5th |
| Spouse’s younger siblings | 3rd from the 7th | 9th |
How to read it
- Strong, well-aspected 3rd and 10th houses and their lords — supportive in-laws.
- Malefics afflicting these houses or lords — friction, distance or duty-heavy relations.
- A good 7th lord and Venus/Jupiter — the spouse bridges the families well.
- The running dasha shows when in-law matters come to the fore.
For harmony
- Respect and patience go further than any remedy; Saturn rewards duty done without resentment.
- For the 10th house (mother-in-law): Monday Shiva worship and respect for elders.
- For the 3rd house (father-in-law): Sun mantra and Surya arghya.
