Payment to NRI in Either or Survivor account

This discussion explores the validity of making payments to an NRI seller via an 'either/or survivor' account where their resident Indian mother is the primary account holder. The buyer deducted TDS based on the NRI status of the son and the resident status of the mother. While the bank issued Demand Drafts (DDs) favouring each seller, mentioning the survivor account, the core question is whether this is acceptable or if an NRO account is mandatory for the NRI. The consensus suggests that as long as TDS is correctly deducted and the buyer obtains a receipt or confirmation from the NRI, their responsibility is fulfilled, and the NRI is accountable for depositing funds into their chosen account.
