I had the same question and I've read section (g) several times. Can we just send one revised privacy notice addressed to the primary accountholder or must the one notice be addressed to all joint accountholders? "If two or more consumers jointly obtain a financial product or service from you, you may satisfy the initial, annual, and revised notice requirements of §§1016.4(a), 1016.5(a), and 1016.8(a), respectively, by providing one notice to those consumers jointly." Thanks.
