You have a horizontal line that you can’t delete in your document. How do you get rid of it? If we are working on a document created by someone else, we probably won’t know how the line was added.

If this pesky horizontal line is not on a table, then it may be a paragraph border. Paragraph borders can be quickly (and sometimes inadvertently) added by typing three or more hyphens and then pressing enter. The border is added to the preceding paragraph.
To remove the paragraph border, put your cursor in the paragraph and go to the Home tab > Paragraph group, and click on the Borders button. Select the No Border option (or any of the other border options that serve), and the horizontal line will be removed.
