Even weak planets becoming significators for happy married life keep the marriage going with short duration of stress and strain in case they are not badly placed and closely afflicted by the functional malefic planets. Marital discord can manifest in a variety of ways:

(a) The spouse may be ill-tempered and be either short tempered or may use abusive or insulting language or have a disrespectful attitude. Possibility of such a situation is greater, when the lord of the ascendant is weak in comparison to the lord of the seventh house and the seventh house or its lord is under the influence of a functional malefic Mars or the lord of the sixth house containing a mooltrikona sign or the lord of the seventh house is placed in the sixth house.

(b) The spouse may have a dull attitude towards physical relationships. This is indicated by the weakness of the lord of the seventh house, especially when it contains the sign Virgo, Aquarius or Cancer or the seventh lord is weak and under the influence of the planets Saturn and Mercury or the planet Venus is weak.

(c) Delay in marriage on account of weakness of the prime determinant of marriage, the significator for the husband or wife and the operative periods of the weak or functional malefic planets. All the factors operating together result in denial of marriage or happiness in marriage or continuance of marriage.

(d) Lack of mental compatibility. The influence of the planets, the Sun, Mars and Venus on the ascendant or the seventh house or their lords make either of the couple extra sensual and proud. The influence of Mercury and Saturn besides weakness of Venus dampens the interest in the matters of sex and causes mental depression. Such an influence on one of the two married partners creates mental incompatibility. Such influences on the Moon cast their impact on the native whose chart is under consideration.

(e) Delay in birth of the children and/or problems to them cause unhappiness in marriage. Main reasons for this may be weakness of the lord of the fifth house, Jupiter, the Sun and Venus. Jupiter is the primary significator for male progeny while the Sun is the secondary significator for male progeny. Venus rules semen and its weakness weakens the sperms in males while the weakness of Venus in female nativities creates problems in conception as Venus rules uterus, ovaries and fallopian tubes. The impact of the most malefic planet on the most effective point of the fifth house denies progeny. The weakness of the second house and afflictions to it denies a male child.

(f) Divorce and separation due to any of the foregoing factors individually or collectively besides ruling periods of the functional malefic planets. The close influence of the functional malefic planet ruling the sixth house and/or Ketu on the second, seventh, fourth or twelfth houses or the weak lords of these houses placed in the sixth house causes divorce while the weakness of these houses causes long separations.

(g) Extra marital relations are governed by the influence of Rahu and the lord of the eighth or twelfth house. The influence of these planets on the ascendant, fourth or the fifth house or their lords impel the native towards extra marital relations. The influence of these planets on the seventh house or its lord and/or significator impels the spouse of the native for sensual pleasures out of marital bond. However, a strong Jupiter and/or the Sun in the nativity keep the tendencies given by Rahu and the lord of the eighth or twelfth house under check.

(h) The impact of the lords of the functional malefic planets on the planets signifying marriage and marital happiness.

(i) The close influence of Rahu on Venus gives excessive urge and indulgence in sensual pleasures and weak health of the spouse may result in out of marital bond and unnatural sensual pleasures.
