Many legal documents include a slimline in the header and/or footer. This is really easy to add to the Theme of your document.
It's easy to create a footer that has a neat slimline that looks like this:
You can create a slimline footer in themes.
Under the footer section select "Show text instead of image" from the drop down menu headed "Type".
Under the "Text" field simply add a series of underscores (i.e. ___) to create a "line". To ensure your slimline is the correct length, you could copy and paste the slimline from your word document precedent, or you can just play around until you get the right length.
Don't forget to apply you Theme to your Bot. You can do that under the Publishing tab.
