Minn. Stat. § 61A.04
In addition to the provisions now required by law to be in the standard form of life insurance policies issued or delivered in this state, there shall be, when such policy provides for the payment to the beneficiary the proceeds thereof, in either monthly, quarterly, semiannual or annual installments, to continue during the lifetime of the beneficiary, or for a stipulated number of years, whenever requested by the insured under the policy, the following provisions:
All rights of the beneficiary to commute, change time of payment or amount of installments, surrender for cash, borrow against or assign for any purpose, are hereby withdrawn and those parts of this policy giving the beneficiary such rights are hereby declared inoperative and void; it being the intent hereof that the beneficiary shall have no right under this contract except to receive the installments at such times and in such amounts as stated in this policy, and all the provisions of this policy in conflict herewith are hereby declared to be inoperative.
This provision may be attached to any policy in the form of a rider thereon, and, when so attached, shall become a part of and form a part of the contract of insurance, evidenced by the policy to all intents and purposes as if set forth at length therein.
