Ketu's Hardest House
Worst depends on the question. For marriage, Ketu in the 7th is the placement that draws the objection, with Rahu on the ascendant.

The 7th, if the question is the spouse
Ketu's most complained-of placement is the 7th house. The south node of severance occupies the spouse's house, and Rahu occupies the lagna, so the personality carries the north node's hunger while the marriage carries detachment. Partners can feel absent, spiritual, or hard to hold in ordinary domestic terms. The 7th lord can still marry the person. The style of the bond is the complaint, not an empty house.
Ketu mahadasha is 7 years. Those years press this marriage story only if they run at a relevant age. A childhood Ketu balance is not a wedding.
The 4th and the 1st are the other candidates
Ketu in the 4th detaches the home and can thin the mother's theme, with Rahu in the 10th driving the career. Ketu in the 1st, which means Rahu in the 7th, puts severance on the body and appetite on the spouse. People call the 1st the worst when the question is health of identity, and the 7th the worst when the question is marriage. There is no house that is worst for moksha, courage, and marriage at once.
Ketu in the 12th is the placement often spared, because the 12th already deals in loss, foreignness, and release, and Ketu's nature agrees with release. Rahu is then in the 6th, an upachaya.
Sign and aspect still edit the word worst
Ketu in the 7th in a sign whose lord is strong is a clearer marriage than Ketu in the 7th with a debilitated 7th lord. Jupiter aspecting the 7th, from the right distance, witnesses the house. A puja does not move Ketu into the 12th where some readers would have preferred it.
Ask what you wanted protected. If it was the spouse, the 7th is the hard placement. If it was the career's satisfaction, look at Ketu in the 10th. Worst is the topic you named, plus the opposite Rahu you forgot to mention.
Frequently asked questions
Why is the 7th singled out for Ketu?
Because marriage readings object to severance in the spouse's house, and that placement puts Rahu in the lagna.
Is Ketu in the 12th worse?
Often it is read more kindly, as release, with Rahu in the 6th. It is a different topic from marriage.
Does Ketu's dasha ruin a 7th-house Ketu?
Ketu's 7 years emphasize it if they fall in adult life. The 7th lord and the Navamsa can still support a wedding.
