Subd. 2. No assignment or garnishment.
A service pension or ancillary benefits paid or payable from the special fund of a relief association to any person receiving or entitled to receive a service pension or ancillary benefits is not subject to garnishment, judgment, execution, or other legal process, except as provided in section 518.58, 518.581, or 518A.53.

A relief association that provides a service pension in a single payment, if the governing articles of incorporation or bylaws so provide, may purchase an annuity contract on behalf of a retiring member in an amount equal to the service pension otherwise payable at the request of the person and in place of a direct payment to the person. The annuity contract must be purchased from an insurance carrier licensed to do business in this state.
Subd. 4. Transfer to individual retirement account.
A relief association that is a qualified pension plan under section 401(a) of the Internal Revenue Code, as amended, and that provides a single payment service pension, at the written request of the applicable retiring member or, following the death of the active member, at the written request of the deceased member's surviving spouse, may directly transfer on an institution-to-institution basis the eligible member's lump-sum pension or the death or survivor benefit attributable to the member, whichever applies, to the requesting person's individual retirement account under section 408(a) of the Internal Revenue Code, as amended.
