So, let's see how different planets will behave differently as 4th house Lord in 7th house.

Sun - Suppose it is a Taurus Ascendant chart and Sun rules the 4th house with Leo sign and sits in the 7th house in the sign of Scorpio. It shows a turbulent and transformative relation with parents and spouse as Sun is in Karmic sign of Scorpio. It shows that your parents tried to interfere so much in your married life that your relationship with spouse went through chaotic changes. It also shows person himself has great ego and that results in having disputes in relation.

Moon - So it is Aries Ascendant Chart and Moon rules the 4th house with Cancer sign and sits in 7th house in Libra. This time native's mother try to interfere in married life but not for worse. Person wants to marry someone with similar nature as his mother. He takes advice of mother before deciding the spouse. As Moon in Libra can easily be termed as a balanced mind, this person seeks to have a balanced relation between spouse and mother.

Mars - Mars can be 4th house ruler through its two signs. So, let's take both one after the other.

Capricorn Ascendant - So if it is Capricorn Ascendant, Mars rules 4th & 11th house and sits in 7th house in Cancer sign, where it is debilitated. If Mars is close to its actual debilitation degree, then it shows power struggle and arguments between you, spouse and mother up to the level where it can break relation. Mars debilitated means person know that he needs to fight but doesn't know how to fight, so in these cases person takes on arguments, physical fights and abuses to resolve the issues but it doesn't help obviously. It also shows that because of disputes with spouse, one ended up in losing the house/land property. Conjunction/aspect of other planets, other yogas and dashas will change the scenario totally.

Leo Ascendant - Now if it is Leo Ascendant, Mars rules 4th & 9th house and sits in 7th house in Aquarius sign. Here things are much better, although Mars is still in enemy sign but not debilitated and not to forget that in other sign of Saturn, Mars is exalted. So, although there may be stress in relation but at the same time person will be protective of spouse. It can also lead to a delayed marriage, which is all good for this mangalik position. It shows someone can be in real estate business and having good property. He needs to remain careful in dealing with spouse and avoid arrogance and dominant behavior.

Mercury - Mercury also can be 4th house ruler through its two signs. So, let's take both one after the other.

Pisces Ascendant - If it is Pisces Ascendant, Mercury rules 4th & 7th houses and sits in 7th house in Virgo. This shows someone who looks for a communicative relationship with spouse. It is very necessary for him to be communicating with spouse, else relation will fail. This shows person who gets a business person as spouse. Spouse will be highly practical and realistic. Their spouse can be in accounting, editing, audit related job. Spouse is very detailed oriented but communication is key for them.

Gemini Ascendant - If it is Gemini Ascendant, then Mercury rules 4th & 1st house and sits in 7th house in Sagittarius. Here also communication becomes a great part of married life and spouse can be in business but here communications are less practical or realistic and more on the topics of religion and higher philosophy. I won't be surprised if spouse is teacher or professor in this case. Couple would love to talk on religious/philosophical topics and that would keep their relation going.

Venus - Venus also can be 4th house ruler through its two signs. So, let's take both one after the other.

Aquarius Ascendant - If it is Aquarius Ascendant, Venus rules 4th & 9th house and sits in 7th house in Leo sign. Venus in 7th house or as 7th house ruler always gives a very beautiful spouse and the relation also is very good and peaceful but when Venus is in Leo it shows a spouse who wants all the best things in life. As Leo is sign of Royal-hood, spouse is never satisfied with mediocre things in life and would demand the best home, best car, best social status which may lead to disputes and disagreements in life.

Cancer Ascendant - If it is Cancer Ascendant, Venus rules 4th & 11th house and sits in 7th house in Capricorn sign. This position of Venus is better than earlier one as spouse will not be very demanding here. Venus is also in friendly sign but here marriage gets delayed as Saturn rules the 7th house and it is better to delay the marriage in these cases. Hence, it ends up in limiting the results of 7th house as person gets married in 30s. Here relationship is based on practicality and realistic attitude of life. Here, it may not be the most romantic relation but it will be a stable marriage.

Jupiter - Jupiter also can be 4th house ruler through its two signs. So, let's take both one after the other.

Virgo Ascendant - If it is Virgo Ascendant, Jupiter rules 4th & 7th house and sits in 7th house in Pisces Sign. Out of all, I think this is best position of 4th lord in 7th house. Most benefic Jupiter in own sign Pisces in 7th house. It shows that not only person gains property and finance from spouse but spouse is highly spiritual person and guides the native like a Guru in life. Relation with spouse is more a spiritual one than romantic. They connect on soul level rather than physical.

Sagittarius Ascendant - If it is Sagittarius Ascendant, Jupiter rules 4th & 1st house and sits in 7th house in Gemini. This is also a good position. All the things narrated above can be seen here also. Additionally, person would require more of communicative relation with spouse. They would want spouse to talk to them regularly over all matters of life.

Saturn - Saturn also can be 4th house ruler through its two signs.

In either sign (Capricorn/Aquarius) as 4th house lord, Saturn in 7th house (for Libra/Scorpio Ascendants respectively) shows that 1st of all marriage should be delayed till 30s at least. If Saturn is in Aries for Libra Ascendant, where it is debilitated, this age of delaying marriage can go even further. Saturn is the planet that really shows that we are mere mortals and even puppets. This shows a clear conflict between spouse and mother. This also shows a stressful relation if person marries in 20s. A good dasha and good moon is very necessary for keeping a good relation.

Rahu - If Rahu is 4th house Lord through its sign Aquarius, as it co-rules Aquarius along with Saturn, and sits in 7th 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 7th house will transform Rahu as Venus as Rahu changes its nature as per the lord of sign it is placed in. So, it will become much like Venus in 7th house as discussed above but at the same time, Rahu's basic nature of insatiable will remain there. It means they always feel that person they got married to is not what they desired for. This position also gives a tendency to cheat on spouse or at least native feels that spouse is cheating on them. This leads to disputes in relations. This also gives a foreign spouse.

Ketu - Likewise, If Ketu is 4th house Lord through its sign Scorpio, as it co-rules Scorpio along with Mars, and sits in 7th 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 from the things related to the house Ketu is sitting, here it actually 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 remains a possibility with Ketu in 7th house always 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.
