(1)    In this section, “open-end credit plan” has the meaning given under s. 421.301 (27). The term includes only those plans governed by chs. 421 to 427.

   (2)   Except as provided under sub. (6), this section does not impose any additional or separate notice requirements on a creditor.

   (3)   The spouse of a person who incurs an obligation described under s. 766.55 (2) (b) and governed by chs. 421 to 427 may exercise rights and remedies available to the incurring spouse under chs. 421 to 427.

   (4)   Section 422.305 does not apply to the spouse of a person who incurs an obligation described under s. 766.55 (2) (b) unless that spouse also signs the writing evidencing the credit transaction or a separate guarantee or similar instrument and unless the other requirements of s. 422.305 are met.

   (5)   The spouse of a person who establishes an open-end credit plan that may result in an obligation described under s. 766.55 (2) (b) may terminate the plan by giving written notice of termination to the creditor. A writing evidencing an open-end credit plan may include a provision that authorizes the creditor to declare the account balance due and payable upon receipt of notice of termination, notwithstanding s. 425.103 or 425.105. Notice of termination does not affect the liability of the incurring spouse or the availability of the incurring spouse’s interest in marital property or other property of that spouse to satisfy obligations incurred under the open-end credit plan, both before and after the notice of termination. Subject to the limits under s. 422.4155 (1), the terminating spouse’s interest in marital property continues to be available under s. 766.55 (2) (b) to satisfy obligations incurred in the interest of the marriage or family both before and after notice of the termination. A creditor may consider in its evaluation of subsequent applications for credit the fact that a prior open-end credit plan offered by the creditor and entered into by the applicant spouse has been terminated under this subsection.

   (6)   Written notice to a spouse under s. 422.415 (2) (a) or (c) concerning an increase in the rate of finance charge is not effective with respect to the interest of the nonincurring spouse in marital property unless notice is given to both spouses. Notice is considered given on the date it is mailed by the creditor. The notice may be enclosed in an envelope addressed to the incurring spouse at the last-known address of that spouse appearing on the records of the creditor if a statement appears on the face of the envelope alerting the spouses that the envelope contains important information for both spouses.

   (7)   With respect to consumer credit transactions, the division of banking may promulgate rules to interpret this chapter and chs. 421 to 427, consistent with the purposes and policies of this chapter and chs. 421 to 427.
