Mangal dosha, also called Kuja dosha, is the dosha of Mars: it forms when Mars occupies the 4th, 7th, 8th, or 12th house of the birth chart, counted from the ascendant. Many traditions also include the 1st house, and many (strongest in South India) add the 2nd as well. The careful check is also run from the Moon and from Venus. A person with the placement is called manglik. The dosha is weighed mainly when two charts are matched for marriage, where it flags a tendency toward friction in partnership, and it comes with a long list of cancellations, beginning with the simplest: when both partners carry it, it cancels entirely.
The checker on this page runs the full test from your birth details. The article around it explains which houses count and why, what a manglik result actually means, and where the cancellations come in.
What is mangal dosha?
Mars in Vedic astrology is intensity itself: energy, drive, heat, the will to act. None of that is bad. The dosha arises only when that fire falls on the specific houses that govern partnership, home, and private life, where the tradition says it can bring friction unless it is balanced. The full profile of the planet is on the Mars page.
The name is plain Sanskrit. Mangal is Mars, Kuja is another of its names, and dosha means blemish or fault. Manglik (sometimes written Mangalik) is the adjective for a person whose chart carries the placement. All three terms describe the same single, checkable condition.
Which houses make you manglik?
The core houses are the 4th, 7th, 8th, and 12th, with the 1st and 2nd added by many traditions. Read what each house governs and the list explains itself, because every one touches the territory a marriage lives in.
| House | What it governs | Why Mars here is flagged |
|---|---|---|
| 4th | Home, inner peace | Restlessness where calm is needed most |
| 7th | The partner, the marriage itself | Mars's drive lands directly on the partnership |
| 8th | The intimate bond, shared fortunes, upheavals | Intensity in the deepest, most private layer of the marriage |
| 12th | The bed, private life, expenditure | Friction in the most personal space two people share |
| 1st (many traditions) | Self, body, temperament | The heat sits in one's own manner and reactions |
| 2nd (many traditions) | Family, speech | Sharp words inside the family circle |
The 7th house is the heart of the matter, since it is the house of the spouse and the marriage, and the other core houses ring it: home, intimacy, and the bedroom. Mars touching any of them warms the relationship's weather, which is exactly why the tradition asks you to look, and then to look for what balances it.
How the check is run
The primary check is from the lagna, the ascendant, which gives the strongest form of the dosha. Many practitioners also run the count from the Moon and from Venus; the counts from Moon and Venus are read as progressively lighter than the ascendant count. Mars in a flagged house from any of the three registers, but an ascendant count carries the most weight in the classical framework.
This is why two sources can disagree about whether the same person is manglik: one checked a single point, the other checked all three, or they differed on the 2nd house. The checker on this page runs all three counts and shows you each one separately, so you can see exactly where the result comes from. All it needs is your birth date, time, and place.
What being manglik actually means
A tendency toward heat in the relationship: strong wills meeting, a quick temper to manage, energy that needs somewhere to go. That is the honest content of the flag, and nothing more. It is not a prophecy about how a marriage ends. Countless steady, happy marriages carry this exact placement.
The arithmetic alone argues for calm. Four to six of twelve houses qualify depending on which tradition is followed, so a large fraction of everyone ever born is manglik before cancellations are even checked. The tradition knows this, which is why it surrounds the rule with so many balancing conditions and why no careful matchmaker reads the dosha apart from the rest of both charts.
What cancels mangal dosha
The cancellations are many, and the kindest is mutual: when both partners carry the dosha, the two cancel each other and the matter is set aside. Beyond that, Mars in its own sign, Aries or Scorpio, or exalted in Capricorn is read as far gentler; the aspect of Jupiter steadies the heat; Mars joined with the Moon softens it; and regional traditions exempt further sign placements.
Each of those rules, with how to weigh it, is covered in full on the dosha cancellation page. The practical point here: a manglik result from the checker is the beginning of the question, never the end of it. The dosha is rarely left standing once the whole chart is read.
Mangal dosha in marriage matching
In matching, the Mars check sits alongside the 36-point koota system, which scores two charts across eight separate factors. The dosha is checked in both charts at once, because the mutual rule can settle it immediately, and the result is weighed together with the koota score, the strength of each 7th house, and the running dasha periods.
Where some heat does remain after all of that, the traditional answer is tending rather than fear: patience cultivated between two strong-willed people, and the ordinary maturity that years bring to any intense temperament. If you are comparing two charts, the matching tool runs the koota table and the Mars check side by side, and the doshas explains how this dosha fits into the wider family.
