N.D. Cent. Code § 35-06-06: Pledge to secure another's obligation - Effect - Withdrawal

Property may be pledged as security for the obligation of a person other than the owner and in so doing the owner has all the rights of a pledgor for the owner except that one who pledges property as security for the obligation of another cannot withdraw the property pledged otherwise than as a pledgor might, and if the owner receives from the debtor a consideration for the pledge, the owner cannot withdraw it without the debtor's consent.
