So first of all, let's see what 1st house/Ascendant and 7th house represent -
1st house/Ascendant is your self, physique, personality, overall health, life path and head in human body etc.
7th house is house of market place, other people (masses), business partnerships, agreements, marriage, spouse, marital happiness etc.
Now, what does it mean to have 1st house lord in 7th house?
It means the planet which rules/controls/owns the 1st house/Ascendant of your horoscope is sitting in the 7th house of horoscope.
Now, what is the impact of having 1st house lord in 7th house?
Its generic interpretation is that person's focus through-out life is on dealing with matters related to spouse, marriage, agreements, contracts etc. These are the people who find their true self from their spouse. Having a relationship is too important for them, they cant stay without relation, but it doesn't mean that every person will deal with relations in same way.
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 1st house lord is going in 7th house. So again, Overall Chart Reading is important.
But again, this generic interpretation can also change as per the planet which is going in 7th house as 1st house lord.
So, let's see how different planets will behave differently as Ascendant Lord in 7th house.
Sun - Suppose it is a Leo Ascendant chart and Sun sits in the 7th house in the sign of Aquarius. Now, it is in enemy sign as Saturn is Sun's Arch-Enemy. Here, this position often leads to ego battles between spouses, Sun is basically a King and in relationship, there is no King-hood. A person has to adjust with another and let go of ego. Here, it becomes tough for the Sun, as it is all about ego. So, this position actually shows a person who is finding it hard to adjust in relations. Letting Go of Ego is key for these people to have a good relation.
Moon - So it is Cancer Ascendant Chart and Moon rules the 1st house and sits in 7th house in Capricorn. Capricorn is again ruled by Saturn, which is not too good with gentle Moon. Cancer is the sign of emotional security and in this situation person tries to find emotional security from the spouse. But guess what, Capricorn is ruled by cold Saturn. So, their spouse are usually not much emotional and very practical in their approach. This is another position where person is trying to find true sense and happiness in marriage and relations. Being Practical is key for these people to have a good relation.
Mars - Mars can be Ascendant ruler through its two signs. So, let's take both one after the other.
For both the Ascendants of Mars (Aries & Scorpio), 7th house is ruled by a Venus ruled sign (Libra & Taurus respectively), so taking both the Ascendants together. Mars going into 7th house in both these Ascendants is in the sign of Venus which is Neutral to Mars, but Mars natural trait is of Dominance and Aggression being a Soldier. Hence, these people sometimes get very argumentative and dominating against their spouse. Controlling of anger and dominance is key for them to have a good relation.
Mercury - Mercury also can be Ascendant ruler through its two signs. So, let's take both one after the other.
For both the Ascendants of Mercury (Gemini & Virgo), 7th house is ruled by a Jupiter ruled sign (Sagittarius & Pisces respectively), so taking both the Ascendants together. Mercury is going into 7th house in sign of enemy Jupiter, but Jupiter and Mercury both are benefic planets. Here, communications become important between the couple. If they don't find a partner who wants to communicate with them on daily basis, then it is hard for them to go through the relation. Communication would be largely on philosophy, religion and spirituality. Being communicative is key for this relation to prosper.
Venus - Venus also can be Ascendant ruler through its two signs. So, let's take both one after the other.
Again, for both the Ascendants of Venus (Taurus & Libra), 7th house is ruled by a Mars ruled sign (Scorpio & Aries respectively), so taking both the Ascendants together. In this case, person has high love desires. They desire a partner much like a Bollywood romance movie. Either they want a super model as wife or a hunk as a husband. It is important for them to be realistic in relationship and be practical about marriage. As Mars is getting involved, intensity will be high in love but same time aggression, anger and dominance may be part of relationship.
Jupiter - Jupiter also can be Ascendant ruler through its two signs. So, let's take both one after the other.
Again, for both the Ascendants of Jupiter (Sagittarius & Pisces), 7th house is ruled by a Mercury ruled sign (Gemini & Virgo respectively), so taking both the Ascendants together. Again, as the most benefic planet, Jupiter ensures a good married life in 7th house. Here, partner will be like a Guide or a Counsel to them throughout life. Spouse is the one which teaches the real meaning of their true self and how to progress in relation meaningfully. Wisdom, Spirituality and Knowledge are foundations for this relation.
Saturn - Saturn also can be Ascendant ruler through its two signs.
Capricorn or Aquarius Ascendant - For either Ascendant, Saturn's results will almost be the same. If Saturn as Ascendant Lord sits in 7th house, first of all it shows a possible delay in marriage till 30 years of age. Then it shows a spouse who is very matured and practical towards life and relationship. This is actually the best planet in 7th house if person in willing to marry late because Saturn represents Stability too. So if person marries late, Saturn will provide a stable relationship. It is not easy to break this relation. Many a times this relation is much like Business dealing between two, where both sides agree to do something for each other in bargain. Not much Bollywood Romance here but practical relationship will be able to take the relation forward.
Rahu - If Rahu is Ascendant Lord through its sign Aquarius, as it co-rules Aquarius along with Saturn, and sits in 7th house in Leo then 1st of all we need to make sure of Saturn's position as it is the main ruler. Rahu in Leo in 7th house means a few things. It means a possible illusive behavior from spouse, i.e, speaking a lie or cheating. Rahu in 7th house becomes a karaka of 2nd marriage, so to avoid any such situation, it is always recommended that one should marry his spouse twice. It also shows that spouse has some foreign link, may be from other culture, language or land. This position requires a lot of compromises and adjustments.
Ketu - Likewise, If Ketu is Ascendant Lord through its sign Scorpio, as it co-rules Scorpio along with Mars, and sits in 7th house in Taurus then it shows an attitude of "Been There, Done That" for marriage. It shows a person not too enthusiastic about marriage and relations. He feels there are much more important things to spend time on than marriage. They need to be very spiritual in their relationship for that relationship to prosper.
