Saturn in the 7th house is the worst position for marriage related matters. Due to the maleficent nature the presence of the Saturn planet can create complications in marriage matter, but if the native handles it well, it can lead to a marital life of the utmost stability.
The real question is whether the chart owner really wants this type of stability, or would they prefer Saturn to block the gates of marriage. Of course, a lot is depending on aspects of other planets that apply on the native’s natal Saturn.
Saturn is the main planet behind most of the cases where delays take place. Although there may be additional planets which may also have a role in this context but they would only be more of contributory nature only to aggravate what trend has set by Saturn in the natal chart. My strong belief that Saturn causes delayed or late marriages is based on the other astrological factors also.
Firstly Saturn is a planet related with obstructions and delays and the effects and influence on the 7th house is the pivotal cause for the rift and dissatisfaction’s in married life, Saturn is the planet and best known for its quality as it is virakt, means ESTRANGED, so it’s influence in married life also leads to the separation, divorce, and disputes in married life.
