Mississippi Code Title 75. Regulation of Trade, Commerce and Investments § 75-9-318

(1) Unless an account debtor has made an enforceable agreement not to assert defenses or claims arising out of a sale as provided in section 75-9-206, the rights of an assignee are subject to

(2) So far as the right to payment or a part thereof under an assigned contract has not been fully earned by performance, and notwithstanding notification of the assignment, any modification of or substitution for the contract made in good faith and in accordance with reasonable commercial standards is effective against an assignee unless the account debtor has otherwise agreed but the assignee acquires corresponding rights under the modified or substituted contract. The assignment may provide that such modification or substitution is a breach by the assignor.

(3) The account debtor is authorized to pay the assignor until the account debtor receives notification that the amount due or to become due has been assigned and that payment is to be made to the assignee. A notification which does not reasonably identify the rights assigned is ineffective. If requested by the account debtor, the assignee must seasonably furnish reasonable proof that the assignment has been made and unless he does so the account debtor may pay the assignor.

(4) A term in any contract between the account debtor and an assignor is ineffective if it prohibits assignment of an account or prohibits creation of a security interest in a general intangible for money due or to become due or requires the account debtor's consent to such assignment or security interest.
