Tamil Marriage Biodata — Format Guide with Jathagam Fields and Tamil Script

A Tamil marriage biodata follows the same six-section structure as any Indian biodata, presented with Tamil script and terminology for the fields that matter most to Tamil families: Natchathiram (birth star) instead of Nakshatra, Rasi with Tamil sign names, Gotram, and precise community identity — Iyer, Iyengar, Mudaliar, Nadar, or Chettiar, often including sub-sect (Vadama or Brahacharanam for Iyer families; Vadakalai or Thenkalai for Iyengar families). Tamil matrimonial culture is Jathagam-led — the horoscope chart is typically exchanged before or alongside the biodata, and porutham (compatibility) is checked before meetings are arranged. Getting Natchathiram and Rasi correct on the biodata is the first filter, not a later step.

Why a Tamil biodata needs Tamil-specific fields

A generic Indian biodata template gives you Nakshatra, Rashi, Gotra — the Sanskrit/Hindi-rooted terms used across most of North and Central India. Tamil matrimonial tradition uses the same underlying astrological system but with Tamil names for the same concepts, and places different emphasis on which fields come first. A biodata using "Nakshatra" instead of "Natchathiram" isn't wrong exactly — the concept is identical — but it reads as generic rather than written for a Tamil family specifically, in the same way a form letter reads differently from one addressed by name.

Tamil biodata fields — what to write

Natchathiram (birth star): The Tamil term for Nakshatra. Same 27 stars, Tamil names: Aswini, Bharani, Krithigai, Rohini, Mirugaseerisham, Thiruvadirai, Punarpoosam, Poosam, Ayilyam, Magam, Pooram, Uthiram, Hastam, Chithirai, Swathi, Visagam, Anusham, Kettai, Moolam, Pooradam, Uthiradam, Thiruvonam, Avittam, Sadayam, Poorattathi, Uthirattathi, Revathi.

Rasi: Same 12 signs as elsewhere in India, Tamil names: Mesham, Rishabham, Mithunam, Katakam, Simmam, Kanni, Tulam, Vrichigam, Dhanusu, Makaram, Kumbham, Meenam. Full explanation → what is Rashi

Gotram: Same concept as Gotra elsewhere in India — patrilineal lineage. Tamil Brahmin (Iyer/Iyengar) Gotrams include Kashyapa, Bharadvaja, Harita, Srivatsa, Mudgala, Koundinya. Full explanation → what is Gotra

Community and sub-sect: Iyer families state Vadama, Brahacharanam, or Ashtasahasram sub-sect. Iyengar families state Vadakalai or Thenkalai. Mudaliar, Nadar, and Chettiar families state their specific sub-community. Chettiar (Nagarathar) families additionally state their pirivu (division) and native Chettinad town.

Jathagam: The full horoscope chart, typically attached as a companion document alongside the one-page biodata — this is the one widely-accepted exception to the one-page rule, since the Jathagam is a separate document, not additional biodata content. See our complete guide on this exception → one page or two?

Frequently asked questions

What is a Tamil marriage biodata?

A Tamil marriage biodata is a marriage biodata written for Tamil-speaking families, using Tamil script and Tamil matrimonial terminology — Jathagam (horoscope chart) instead of generic Kundali, Natchathiram instead of Nakshatra, Rasi with Tamil sign names, and community identity (Iyer, Iyengar, Mudaliar, Nadar, Chettiar) stated with the precision Tamil families expect. It follows the same six-section structure as any Indian biodata but is presented bilingually or fully in Tamil for families who prefer it, and is typically exchanged alongside the Jathagam chart as a companion document.

What is the difference between Nakshatra and Natchathiram?

Nakshatra and Natchathiram refer to the exact same thing — the Vedic birth star, one of 27 lunar constellations. Nakshatra is the Sanskrit/Hindi term; Natchathiram (நட்சத்திரம்) is the Tamil term for the identical astronomical and astrological concept. A Tamil biodata uses Natchathiram; a Hindi or general biodata uses Nakshatra. The underlying calculation and the 27 stars themselves are the same across all Indian language traditions — only the name changes.

Why do Tamil families check the Jathagam before anything else?

Tamil matrimonial tradition is porutham-led — horoscope compatibility across traditionally ten factors is assessed by a family astrologer before the families invest time in meetings. This means the Jathagam (birth chart) with accurate Natchathiram and Rasi is often exchanged before or alongside the biodata itself, not after initial interest is confirmed as in some other regional traditions. Getting these fields right on the biodata is therefore not optional detail — it is the first filter.

Should a Tamil biodata be written in Tamil or English?

Both are common and acceptable. Many Tamil families, particularly in Chennai and other Tamil Nadu cities, use English-language biodatas with Tamil terms for community-specific fields (Natchathiram, Rasi, Gotram, community name). Families circulating biodatas primarily among Tamil Nadu relatives, or older-generation family members, often prefer a fully Tamil biodata. Diaspora Tamil families (Singapore, Malaysia, Sri Lanka, North America) frequently use English with Tamil terms retained for horoscope fields, since English is the shared working language across the extended family network.
