Adding Text To Form

Is there an easy way to add text to a form other than going to the header.
Let's say for instance I want to get someones agreement in a field to a particular text(in this instance an agreement to represent them). I would prefer to place it just above that particular field in html. I don't see an easy way to insert the html in the body of the form between fields, so I have been putting it in the header.
Thanks
