Today, 10th house lord sitting in 7th house.

So first of all, let's see what 7th house and 10th house represent -

7th house is house of market place, other people (masses), business partnerships, agreements, marriage, spouse, marital happiness etc.

10th house represents things like Government, Father, Authority, Fame, Work Environment etc. Here, Authority should not be understood in literal sense, like someone got a Government job or became a Manager or CEO of a Firm. Here Authority means doing any work with complete perfection and your opinion matters when comes to making any decision related to that work, so even a good Hacker can be a person of authority as he is master of that particular work. 10th house is one of the houses normally checked for Career/Work/Duty in Life.

Now, what does it mean to have 10th house lord sitting in 7th house?

It means the planet which rules/controls/owns the 10th house of your horoscope is sitting in the 7th house of horoscope.

Now, what is the impact of having 10th house lord sitting in 7th house?

One of the interpretations that can be given to this position is that person is like married to his work. It means they will be as dedicated to their work as a normal person is dedicated to family and marriage. As 10th lord is in 7th house of Business, this is also a position where person should ideally be in Business then Jobs. It also shows that your spouse is coming from your work place only. As Kendra lord is in another Kendra house, it is one of the most powerful Raj Yoga. As 7th house deals with Agreements and Court Halls, this position also shows a Lawyer or a Counselor, may be a relationship counselor.

Now, results may be different due to aspect, conjunctions of other planets or the planet being Retrograde or Combust. Moreover, now we also need to check the strength of 7th house lord as 10th house lord is going in 7th house. So again, Overall Chart Reading is important.

So, let's see how different planets will behave differently as 10th house Lord in 7th house.

Sun - Suppose it is a Scorpio Ascendant chart and Sun rules the 10th house with Leo sign and sits in the 7th house in the sign of Taurus. As Sun is not in friendly sign, this shows that person has lots of fire/anger/ego in him by which he wants to dominate other people. If they are in Business, they will try to dominate their partner. If they are in marriage, they will dominate spouse. Ego battles will lead to chaos in relation. Here, if spouse is submissive, the marriage will sustain else ego battles may end up the relation. But this position makes a good public manager. They like to rule over people around them. Ego is something they need to be careful of.

Moon - So it is Libra Ascendant Chart and Moon rules the 10th house with Cancer sign and sits in 7th house in Aries sign. Here, mind is all in relationship as Moon represents Mind. It shows an impulsive partner. Even the marriage may be impulsive as couple may have met in their work place, love at 1st sight and they impulsively got married. Mind is aggressive & active and they bring same aggressiveness and impulsive nature in marriage, but as it is still a benefic planet, I don't see any major problem in marriage because of this position alone.

Mars - Mars can be 10th house ruler through its two signs. So, let's take both one after the other.

Cancer Ascendant - So if it is Cancer Ascendant, Mars rules 10th & 5th house and sits in 7th house in Capricorn sign, where Mars is exalted. As Mars is in the highest dignity, here person will become like a guard or protector of relationship. Although, Mars is a natural malefic planet and can cause dominance and arguments in marriage or business, but person will always argue here for the rightest reason and for the common benefit. As Mars is in sign of Law & Order & in house of Courts, it certainly shows a strong-willed Lawyer.

Aquarius Ascendant - Now if it is Aquarius Ascendant, Mars rules 3rd & 10th house and sits in 7th house in Leo sign. Mars is in sign of Govt again as Leo is ruled by Sun. So, it shows someone working for Govt as a Soldier or Police or Govt Counsel. It also shows who has partnership Business with Govt Agencies. Here, dominant & aggressive nature and arguments can be a problem for relationship as Mars is in a fiery sign of Leo. So, Mars basic aggressive nature is getting added fuel of Leo.

Mercury - Mercury also can be 10th house ruler through its two signs. So, let's take both one after the other.

Virgo Ascendant - If it is Virgo Ascendant, Mercury rules 10th & 1st houses and sits in 7th house in Pisces, where it is debilitated. This shows someone who connects with other people either through Business or Writing. Mercury in 7th house is one position which throws person in Business sooner or later. If Mercury is in Revati Nakshatra, then it shows most imaginative & creative writer. Relationship is based on communications and spirituality.

Sagittarius Ascendant - If it is Sagittarius Ascendant, then Mercury rules 7th and 10th house and sits in 7th house in Gemini. This is more a position of Businessman as Mercury is in own sign of Gemini, a sign of Business. Here again, relationships are communications based. If couple can't communicate with each other well enough, then relationship will face hard times. This person can also be a very good writer, counselor or salesman.

Venus - Venus also can be 10th house ruler through its two signs. So, let's take both one after the other.

Leo Ascendant - If it is Leo Ascendant, Venus rules 10th & 3rd house and sits in 7th house in Aquarius sign. It shows that person is either involved in any work related to higher goals, social welfare or working in large organizations from where his wealth comes. It shows a beautiful relations with Spouse or Business Partners. If they go into Business, they will be in products related with females or extreme creativity and new technology.

Capricorn Ascendant - If it is Capricorn Ascendant, Venus rules 5th & 10th house and sits in 7th house in Cancer. This shows a person who connects with people on the basis of service, devotion and emotions. Here, a person gets a spouse who is very motherly. Person may be in work related to serving and taking care of elderly ladies. Even if they are in entertainment business, they will be known for playing very emotional roles.

Jupiter - Jupiter also can be 10th house ruler through its two signs. So, let's take both one after the other.

Pisces Ascendant - If it is Pisces Ascendant, Jupiter rules 10th & 1st house and sits in 7th house in Virgo Sign. This is another position which can make you a Lawyer as Jupiter is the natural Karaka of Counselor, Sagittarius is also a sign related with Law and Virgo is the sign of conflicts, it surely shows a counselor. Another work it can show is a Professor/Teacher. Here, person becomes kind of guide or guru to spouse and counsels him/her through life. They can be financial analyst too.

Gemini Ascendant - If it is Gemini Ascendant, Jupiter rules 7th & 10th house and sits in 7th house in Sagittarius. This is like getting married to a Priest :). A highly learned, philosophical and spiritual person as spouse. This is more a position of a Professor/Teacher. Even if they don't go into that field, in Society, they will always be seen as a Guru and people will always come to them for guidance. A very good position for marriage.

Saturn - Saturn also can be 10th house ruler through its two signs.

In either sign (Capricorn/Aquarius) as 10th house lord, Saturn in 7th house (for Aries/Taurus Ascendants respectively) indicates a delayed marriage. Early marriage here won't be good. Early marriage bring stress and sudden events with spouse which may even break the relation. But if delayed, it will be a stable relation based on practicalities of life. Spouse will be of elderly age, matured and very realistic/practical about life. Spouse/Person may be working for Govt or Law Field. Here, it gives a spouse who is of strict religious views and beliefs and this strictness brings all the troubles in relationships. So, person must delay the marriage till 30s at least in this case. For Aries Ascendant, Saturn will be exalted, so situations will be little better. Spouse/Person can be a Businessman/Lawyer. For Taurus Ascendant, it shows a transformative relation as Saturn will be in Scorpio sign. For both positions, relations need to be based on extremely realistic and practical values. Bollywood Romance won't work here.

Rahu - If Rahu is 10th house Lord through its sign Aquarius, as it co-rules Aquarius along with Saturn, and sits in 7th house in Scorpio then 1st of all we need to make sure of Saturn's position as it is the main ruler. Rahu in Scorpio in 7th house will transform Rahu as Mars as Rahu changes its nature as per the lord of sign it is placed in. At the same time, Rahu's basic nature of being insatiable will remain there. Rahu in Scorpio in 7th house basically shows a marriage into a completely different religion or with a Foreigner. There will be something uniqueness attached with marriage. This person or spouse or both will be obsessed about occult and mystic world. Rahu in 7th house is one of karaka of 2nd marriage, so it is better to go with thorough horoscope matching before marriage. As Scorpio represents transformation, if person goes through Rahu, Mars or Ketu MD, which will activate 7th house, person may go through most transformative times in relations. Any Business related with Occult is going to be benefic.

Ketu - Likewise, If Ketu is 10th house Lord through its sign Scorpio, as it co-rules Scorpio along with Mars, and sits in 7th house in Leo then 1st of all we need to make sure of Mars' position as it is the main ruler. As Ketu isolates/separates a person from the things related to the house Ketu is sitting, here it separates person from the concept of being in relation. They are not one of those who are looking out for their first or next partner. They are quite content and spiritual about themselves and their relations. It always remains a possibility with Ketu in 7th house that person is disinterested towards relations. The only way relation can survive in such cases is that couple becomes highly spiritual in matters of relations, means they are happy with whomsoever they marry with no expectations at all. Conjunction/Aspect of a benefic planet may change the situation altogether. Ketu in Leo makes person disinterested towards Creativity and fun side of life. They also don't want to wield any authority over anyone.
