A father-in-law nominated his wife for a deposit in a cooperative society, which was registered. After his death, the society refused to pay the nominee, claiming the nomination was invalid. Experts suggest the nominee can pursue legal action, potentially through a consumer forum, as the society's refusal after accepting and registering the nomination may be considered unfair trade practice. While the nominee is authorised to receive the funds, other legal heirs may still have claims unless a will states otherwise.
