Vedic astrology is a system of astrology that originated in ancient India and is based on the movement of the planets and the stars. Vedic astrology can be used to analyze various aspects of life, such as marriage, career, health, and spirituality. One of the topics that Vedic astrology can address is the possibility of divorce or separation in a marital relationship. 

There are many factors that can affect the divorce prospects of a person, such as:  

• Infidelity or an extramarital affair
• Trouble with finances
• Lack of communication and equality
• Constant arguing
• Weight gain
• Unrealistic expectations
• Lack of intimacy 

However, sometimes the divorce prospects are not due to these personal factors, but due to the unfavorable planetary positions and combinations in the birth chart of the person. Some of the astrological factors that can indicate the possibility of divorce are: 

• Malefic planets in the 7th house: The 7th house represents marriage and partnerships, and the presence of malefic planets like Saturn, Mars, Rahu, or Ketu in this house can indicate marital discord and potential divorce. These planets can cause conflicts, disagreements, dissatisfaction, and instability in the relationship. The effect of these planets can be more pronounced if they are debilitated, retrograde, or aspected by other malefic planets. For example, if Mars is placed in the 7th house in the signs of Aries, Scorpio, or Aquarius, it can indicate a higher likelihood of conflicts and disputes in the relationship.
• Weak Venus: Venus is the planet of love and relationships, and it plays a pivotal role in determining the harmony in marital life. If Venus is weak or afflicted by malefic planets, it can indicate a lack of love, affection, attraction, and compatibility in the relationship. A weak Venus can also indicate a tendency to seek pleasure outside the marriage, which can lead to infidelity and betrayal. For example, if Venus is debilitated in Virgo, combust by the Sun, or expected by Saturn, it can indicate a weak Venus.
• 8th and 12th house connection: The 8th house represents transformation, endings, and the unknown, and the 12th house represents loss, isolation, and detachment. If these two houses are connected to the 7th house or its lord, it can indicate a higher likelihood of divorce or separation. The connection can be through conjunction, aspect, exchange, or placement. For example, if the 7th lord is placed in the 8th house, or the 8th lord is placed in the 7th house, or the 7th and 8th lords are in mutual aspect, it can indicate a higher likelihood of divorce or separation.
• The Moon: Moon is the planet of mind, emotions, and feelings, is weak, debilitated, retrograde, combust, or afflicted by malefic planets. Moon is the significator of mind and emotions and any weakness or affliction to it can reduce the mental and emotional compatibility between the couple and cause divorce.
• The Mars: Mars is the planet of energy, action, and passion, is weak, debilitated, retrograde, combust, or afflicted by malefic planets. Mars is the significator of courage, strength, and aggression and any weakness or affliction to it can reduce the confidence, enthusiasm, and initiative of the person and cause divorce.
• The Rahu: Rahu is the shadow planet of disruption and instability, is placed in the 7th house or aspects the 7th house, 7th lord, or Venus. Rahu is the planet of illusion and deception and its influence on the 7th house or its significators can create confusion, doubt, and suspicion in the marital relationship and cause divorce.
• The Ketu: Ketu is the shadow planet of detachment and isolation, is placed in the 7th house or aspects the 7th house, 7th lord, or Venus. Ketu is the planet of separation and liberation and its influence on the 7th house or its significators can create detachment, indifference, and isolation in the marital relationship and cause divorce.
• Divorce yogas: There are certain planetary combinations and yogas that can indicate the possibility of divorce or separation in Vedic astrology. Some of these yogas are:
  • Kalathra Dosha: This is a dosha or affliction that affects the 7th house or its lord, and causes problems in marriage. This dosha can be caused by the presence of malefic planets in the 7th house or its lord, or the aspect of malefic planets on the 7th house or its lord. This dosha can also be caused by the placement of the 7th lord in the 6th, 8th, or 12th house, or the association of the 7th lord with the 6th, 8th, or 12th lord. This dosha can cause delays, obstacles, disputes, and divorce in marriage.
  • Manglik Dosha: This is a dosha or affliction that is caused by the placement of Mars in the 1st, 4th, 7th, 8th, or 12th house from the ascendant or the moon. This dosha can cause problems in marriage, such as conflicts, violence, accidents, or death of the spouse. This dosha can be nullified by marrying another person who has the same dosha, or by performing certain remedies, such as fasting, chanting, or donating.
  • Rahu-Ketu Dosha: This is a dosha or affliction that is caused by the placement of Rahu and Ketu in the 1st, 5th, 7th, or 9th house from the ascendant or the moon. This dosha can cause problems in marriage, such as misunderstandings, differences, separation, or divorce. This dosha can also affect the progeny and the health of the spouse. This dosha can be nullified by performing certain remedies, such as wearing gemstones, performing poojas, or donating.
