a. Is in substantial compliance with the applicable requirements for tax exemption under s. 401(a), s. 403(a), s. 403(b), s. 408, s. 408A, s. 409, s. 414, s. 457(b), or s. 501(a) of the Internal Revenue Code of 1986, as amended; or

(b) It is not necessary that a fund or account that is described in paragraph (a) be maintained in accordance with a plan or governing instrument that is covered by any part of the Employee Retirement Income Security Act for money or assets payable from or any interest in that fund or account to be exempt from claims of creditors under that paragraph.

(c) Any money or other assets that are exempt from claims of creditors under paragraph (a) do not cease to qualify for exemption by reason of a direct transfer or eligible rollover that is excluded from gross income under s. 402(c) of the Internal Revenue Code of 1986.

(d) Any fund or account described in paragraph (a) is not exempt from the claims of an alternate payee under a qualified domestic relations order or from the claims of a surviving spouse pursuant to an order determining the amount of elective share and contribution as provided in part II of chapter 732. However, the interest of any alternate payee under a qualified domestic relations order is exempt from all claims of any creditor, other than the Department of Revenue, of the alternate payee. As used in this paragraph, the terms "alternate payee" and "qualified domestic relations order" have the meanings ascribed to them in s. 414(p) of the Internal Revenue Code of 1986.

(e) This subsection applies to any proceeding that is filed on or after the effective date of this act.
