Minn. Stat. § 325G.041: MARRIED WOMAN; NAME ON CARD.

If a financial transaction card issuer has determined in the normal course of business that it will issue a card to a married woman, the card shall be issued bearing either her current or former surname, as the woman may direct.

Financial transaction card issuers may require that a married woman requesting a card in a former surname open a new account in that name. Refusal to issue a financial transaction card pursuant to this section constitutes an unfair discriminatory practice under section 363A.16.
