Every page of a Microsoft Word document will display the same footer -- unless you set up different footers for different sections. Even after inserting a section break, the footers will look the same across all sections until you unlink them by turning off the same-as-previous setting, officially termed Link to Previous. In Microsoft Word 2007 and 2010, you can access this option on the ribbon after opening the tab that contains the footer tools.
Navigate to the section of your Word document for which you want to unlink the footer. You can use any page in the section that you want to unlink, as long as the section isn't the first section in the document.
Double-click on the footer.
Click the "Link to Previous" button, located in the Navigation module on the ribbon.
Click the "Close Header and Footer" button, located on the right end of the ribbon.
