(a) Individual accounts. A creditor shall not refuse to grant an individual account to a creditworthy applicant on the basis of sex, marital status, or any other prohibited basis.

(b) Designation of name. A creditor shall not refuse to allow an applicant to open or maintain an account in a birth-given first name and a surname that is the applicant's birth-given surname, the spouse's surname, or a combined surname.

(c) Action concerning existing open-end accounts—

(1) Limitations. In the absence of evidence of the applicant's inability or unwillingness to repay, a creditor shall not take any of the following actions regarding an applicant who is contractually liable on an existing open-end account on the basis of the applicant's reaching a certain age or retiring or on the basis of a change in the applicant's name or marital status:

(i) Require a reapplication, except as provided in paragraph (c)(2) of this section;

(ii) Change the terms of the account; or

(iii) Terminate the account.

(2) Requiring reapplication. A creditor may require a reapplication for an open-end account on the basis of a change in the marital status of an applicant who is contractually liable if the credit granted was based in whole or in part on income of the applicant's spouse and if information available to the creditor indicates that the applicant's income may not support the amount of credit currently available.

(d) Signature of spouse or other person—

(1) Rule for qualified applicant. Except as provided in this paragraph, a creditor shall not require the signature of an applicant's spouse or other person, other than a joint applicant, on any credit instrument if the applicant qualifies under the creditor's standards of creditworthiness for the amount and terms of the credit requested. A creditor shall not deem the submission of a joint financial statement or other evidence of jointly held assets as an application for joint credit.

(2) Unsecured credit. If an applicant requests unsecured credit and relies in part upon property that the applicant owns jointly with another person to satisfy the creditor's standards of creditworthiness, the creditor may require the signature of the other person only on the instrument(s) necessary, or reasonably believed by the creditor to be necessary, under the law of the state in which the property is located, to enable the creditor to reach the property being relied upon in the event of the death or default of the applicant.

(3) Unsecured credit—community property states. If a married applicant requests unsecured credit and resides in a community property state, or if the applicant is relying on property located in such a state, a creditor may require the signature of the spouse on any instrument necessary, or reasonably believed by the creditor to be necessary, under applicable state law to make the community property available to satisfy the debt in the event of default if:

(i) Applicable state law denies the applicant power to manage or control sufficient community property to qualify for the credit requested under the creditor's standards of creditworthiness; and

(ii) The applicant does not have sufficient separate property to qualify for the credit requested without regard to community property.

(4) Secured credit. If an applicant requests secured credit, a creditor may require the signature of the applicant's spouse or other person on any instrument necessary, or reasonably believed by the creditor to be necessary, under applicable state law to make the property being offered as security available to satisfy the debt in the event of default, for example, an instrument to create a valid lien, pass clear title, waive inchoate rights, or assign earnings.

(5) Additional parties. If, under a creditor's standards of creditworthiness, the personal liability of an additional party is necessary to support the credit requested, a creditor may request a cosigner, guarantor, endorser, or similar party. The applicant's spouse may serve as an additional party, but the creditor shall not require that the spouse be the additional party.

(6) Rights of additional parties. A creditor shall not impose requirements upon an additional party that the creditor is prohibited from imposing upon an applicant under this section.

(e) Insurance. A creditor shall not refuse to extend credit and shall not terminate an account because credit life, health, accident, disability, or other credit-related insurance is not available on the basis of the applicant's age.
