1. Saturn’s Influence on the 7th House

• Saturn in the 7th House: Saturn is known for delay, restriction, and discipline. If Saturn is placed in the 7th house (house of marriage), it often causes delays in marriage.
• Saturn Aspecting the 7th House or Lord: When Saturn aspects the 7th house or the lord of the 7th house, it can result in late marriage.
• Saturn in Navamsa: The presence of Saturn in the Navamsa chart can also indicate delays or obstacles in finding a partner.

2. Malefic Influence on the 7th House or 7th Lord

• Mars, Rahu, or Ketu in the 7th House: Malefic planets in the 7th house can create difficulties in relationships and lead to delays.
• Afflicted 7th Lord: If the 7th house lord is debilitated, combust, or under malefic aspects, marriage may get delayed.

3. Weak Venus

• Afflicted Venus: Venus represents love and marriage, and its affliction by malefics like Saturn, Rahu, or Mars can delay marriage.
• Debilitated Venus: If Venus is debilitated or placed in an unfavorable house like the 6th, 8th, or 12th, it can contribute to delays.

4. 12th House Affliction

• Malefic Planets in the 12th House: The 12th house is related to bed pleasures and marital happiness. If it is afflicted by malefic planets, it can lead to delays or dissatisfaction in marriage.

5. Retrograde Planets

• Retrograde Saturn, Venus, or Jupiter: Retrograde planets, especially those related to marriage, such as Venus (relationship) and Jupiter (husband in a female chart), can delay marital events.

6. Strong Influence of the 6th, 8th, or 12th Houses

• 6th House Influence: The 6th house represents obstacles and disputes. If it has a strong influence on the 7th house, delays and problems related to marriage are possible.
• 8th House Influence: The 8th house governs difficulties and sudden events. A strong connection between the 8th and 7th houses can cause delays.
• 12th House Influence: A strong 12th house or its lord’s influence on the 7th house or Venus can result in delays or separations.

7. Weak or Malefic Jupiter (for Female Charts)

• In female horoscopes, Jupiter represents the husband. If Jupiter is weak, retrograde, or afflicted by malefic planets, it may result in delayed marriage.

8. Combination of Saturn and Moon (Punarphoo Dosha)

• Saturn and Moon Aspect or Conjunction: This combination causes delay in fulfilling emotional or domestic desires, including marriage.

9. Manglik Dosha (Mars in 1st, 4th, 7th, 8th, or 12th House)

• If Mars is placed in any of these houses, it can cause delays, hurdles, or difficulties in married life.

10. Dasha and Antardasha Periods

• Sometimes, even if the planetary placements are supportive of marriage, if the person is running the dasha (major period) or antardasha (sub-period) of malefic planets or planets that don’t support marriage, it can delay the event.

11. Ketu’s Influence on the 7th House

• Ketu in the 7th House: Ketu tends to bring detachment and separation. Its placement in the 7th house may indicate disinterest in marriage or delays.

Other Factors:

• Marriage Timing: Marriage may also be delayed if there is an unfavorable planetary period (dasha) running during the ideal marriageable age.
• Navamsa Chart (D9 Chart): A detailed analysis of the Navamsa chart is also essential in understanding the marital prospects and potential delays.

While these combinations can indicate delays, remedies in Vedic astrology, such as wearing certain gemstones or performing rituals (pujas), are often suggested to mitigate negative influences and reduce the delay.
