Mars positioned in the first, second, fourth, seventh, eighth or twelfth house in a Kundali creates Mangal Dosha. Mangal Dosha should be checked not only in the Lagna chart but also in the Moon chart and Venus chart. A person is Non-Manglik only if none of the three charts is afflicted by Mars. Mangal Dosha is also known as Kuja Dosha and Bhauma Dosha. The person having Mangal Dosha is known as Manglik.
