What documents or details are needed for the puja?

For the Sankalp you need: your full name (as per horoscope), your father full name, your gotra (use Kashyap Gotra if unknown), current city and country of residence, and the specific dosha you are addressing. No government ID is required. If performing the puja for a deceased family member, bring their name, gotra, and approximate death tithi. The pandit will ask for these details verbally during Sankalp — no written documents are needed.
