Miss. Code § 11-7-3
The assignee of any chose in action may sue for and recover on the same in his own name, if the assignment be in writing. In case of a transfer or an assignment of any interest in such chose in action before or after suit brought, the action may be begun, prosecuted and continued in the name of the original party, or the court may allow the person to whom the transfer or assignment of such interest has been made, upon his application therefor, to be substituted as a party plaintiff in said action. If in any case a transfer or assignment of interest in any demand or chose in action be made in writing before or after suit is filed, to an attorney or firm of attorneys, appearing in the case, it shall be sufficient notice to all parties of such assignment or transfer, if such assignment or transfer be filed with the papers in said cause, and such attorney or attorneys shall not be required to be made parties to said suit. An "assignee" for purposes of this section includes both absolute assignees, with or without recourse, and conditional or limited assignees including assignees for collection purposes.
