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

So first of all, let's see what 7th house & 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 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.

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

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

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

Its generic interpretation is that you look for and get a spouse who is high on social status in whichever field. It can be any field from Business to Corporate to Politics to Govt etc but you are looking to gain status from Marriage. This also shows you and your spouse may belong to same work environment or Career, much like those Colleague turned Lovers stories. It also shows that you are aware that marriage is more of a responsibility and duty. Overall, it is a placement of people who want to marry a person of high authority.

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 10th house lord as 7th house lord is going in 10th house. So again, Overall Chart Reading is important.

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

Sun - Suppose it is a Aquarius Ascendant chart and Sun rules the 7th house with Leo sign and sits in the 10th house in Scorpio. It shows that your spouse/father may be working for Govt, Law & Administration. Here, spouse and native gain the authority but as Scorpio is sign of Transformations, it either shows that marriage is going through lots of sudden and transformative events or the spouse is working in real chaotic and unusual work environment, like working in night shifts or any other unusual jobs. Here, Authority comes but marriage and work may go through sudden events. Again, any other yoga or dasha can change the scenario totally.

Moon - So it is Capricorn Ascendant Chart and Moon rules the 7th house with Cancer sign and sits in 10th house in Libra. It shows a motherly and nurturing spouse who may be from health care field. Moon in Libra would seek balance between Marriage and Work. If their work life is not going well, they won't feel 100% in marriage. Moon in Libra in 10th house means person's balance of mind is through Work. It may also give a spouse who is business oriented as Libra is sign of Business.

Mars - Mars can be 7th house ruler through its two signs. So, let's take both one after the other.

Libra Ascendant - So if it is Libra Ascendant, Mars rules 7th & 2nd house and sits in 10th house in Cancer sign, where it is debilitated. If it is close to the exact degree of debilitation, it shows that married life may go through a rough time due to Work of Spouse. Like, spouse is so busy with work that he/she has no time for relation. It also shows that spouse may have sudden burst of anger which may result into even physical fights and spoiling of relations. This may show a lack of trust in relationship and spouse may try to dominate the native, which may result into hard times for relations. Again, any other yoga or dasha can change the scenario totally.

Taurus Ascendant - Now if it is Taurus Ascendant, Mars rules 7th & 12th house and sits in 10th house in Aquarius sign. Although, Mars is still in enemy sign but this is much better position than earlier one. Both positions of Mars here will give a spouse that is very dominant and masculine. This shows that spouse may be working in a high authority position in Large Organizations or with some group of people with a higher cause. But as Mars is still in enemy sign, it shows that spouse has sudden bursts of anger in relationship or even at work place. They may still try to dominate the native.

Mercury - Mercury also can be 7th house ruler through its two signs. So, let's take both one after the other.

Sagittarius Ascendant - If it is Sagittarius Ascendant, Mercury rules 7th & 10th houses and sits in 10th house in Virgo, where it is exalted. This shows that spouse is very business and work oriented. He/She is very precise with her communications, means they will speak with least words, still very effective with communications. Spouse can be in field of Accounts, Audit and Editing. They can be Govt Auditor. If they go into business, they will be very shrewd. Here, marriage relationship will be based on highly practical terms and it is more like a business deal between two.

Pisces Ascendant - If it is Pisces Ascendant, then Mercury rules 4th and 7th house and sits in 10th house in Sagittarius. Here, it is a Philosopher, Teacher or a Professor as a Spouse. Here, Spouse is highly educated & learned and may be working as Professor/Teacher with Govt. They can be Lawyer too. Here, relationship depends on communications and communications will be regarding religion, philosophy, world wisdom and higher learning. So, this is a relation where couple will actually learn a lot from each other. The more they communicate about these things, the better their marriage will be.

Venus - Venus also can be 7th house ruler through its two signs. So, let's take both one after the other.

Scorpio Ascendant - If it is Scorpio Ascendant, Venus rules 7th & 12th house and sits in 10th house in Leo sign. It shows a spouse who is highly creative and may be pursuing same creativity in Career, as planet of creativity is in the sign of creativity and in the house of Career. This is one position where person really wants to marry someone of high authority, status and fame. Leo is worldwide fame and Venus there shows that person would love Fame and Status. Here, spouse loves a lavish life. Even if they are going for a breakfast, they want to go to the best restaurant of Town. As Venus feels burnt in Leo, this attitude may start burning the relation after sometime.

Aries Ascendant - If it is an Aries Ascendant, Venus rules 2nd & 7th house and sits in 10th house in Capricorn. Here, there is love for Authority, Rank and Status. Here, spouse may be working with Govt in high position. Although, Venus is in friendly sign, but Saturn is Saturn for all. So, here person feels restrictions in relationships may be because of the time spouse has to give at work. Here, status and rank come out of hard work. Overall, it is a good position but couple needs to show little patience in relation.

Jupiter - Jupiter also can be 7th house ruler through its two signs. So, let's take both one after the other.

Gemini Ascendant - If it is Gemini Ascendant, Jupiter rules 7th & 10th house and sits in 10th house in Pisces Sign. A married life filled with Wisdom, Spirituality and Religious discussions are part of married life. It is like getting married to Gautama Buddha. Spouse will be like a Guru, not only to native but also in Career and Society. People will look at Spouse as Guru, Counselor or Teacher type of person. They may actually be working as Counselors or Teachers. Out of all positions, this is the best I guess.

Virgo Ascendant - If it is Virgo Ascendant, Jupiter rules 4th & 7th house and sits in 10th house in Gemini. Similar results here too but to a lesser impact as Jupiter is in enemy sign. Here, also spouse is in Teaching/Counseling field or at least seen as a Guru at his work place but there would always be a feeling of lack of achievement with this Jupiter, as it is in its fall sign. Still, Jupiter is benefic everywhere, so I don't see any real problem in relations. Spouse is still a highly learned and wise person.

Saturn - Saturn also can be 7th house ruler through its two signs.

In either sign (Capricorn/Aquarius) as 7th house lord, Saturn in 10th house (for Cancer/Leo Ascendants respectively) shows that person had a distant relation with father, for various reasons. It shows someone reaching authoritative position in life only after sheer hard work and dedication. Nothing comes easy in life where Saturn is placed. It shows person had real struggle with any authority figure in life. Even a watchman will show him attitude when time is wrong. This shows someone making a career in Law or Govt Administration. They can also become a Judge but all good things related with Saturn comes when they are in their 30s. Before that it is only a struggle to find out why everyone around them has so much attitude over their authority? In marriage matters, the marriage should be delayed till 30s at least. Any relation before that will end up as burden and responsibility. If Saturn is in Aries here for Cancer Ascendant where it is debilitated, the results may even be more intense. Married life in true meanings start after mid 30s. Till then, marriage is more of a restrictive relation and responsibility.

Rahu - If Rahu is 7th house Lord through its sign Aquarius, as it co-rules Aquarius along with Saturn, and sits in 10th house in Taurus then 1st of all we need to make sure of Saturn's position as it is the main ruler. Rahu in Taurus in 10th house will transform Rahu as Venus 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 Taurus in 10th house basically indicates that your spouse can be from Foreign Origin but yet working in same work environment as yours. It gives a spouse who is highly wealthy and who may bring lots of wealth in marriage. This relation will depend on material desires of couple and how much they can fulfill each other's desire. This is 100% materialistic relation.

Ketu - Likewise, If Ketu is 7th house Lord through its sign Scorpio, as it co-rules Scorpio along with Mars, and sits in 10th house in Aquarius then 1st of all we need to make sure of Mars' position as it is the main ruler. As Ketu isolates/separates a person/spouse from the things related to the house Ketu is sitting, here person/spouse won't be willing to work under any authority or Govt. Working in Corporate is like worst dream for them. They are better of working for own. Relationship wise, it may indicate a spiritual spouse who is highly interested in Occult and Mysticism. Relationship with Father is not to talk about. Either they are physically separated from Father or they never find that mental connect with him. It is better for these people to either work for themselves and be their own authority or follow a spiritual career. They are the last people who are looking for any authority over any other.
