Ask HN: How do you collaborate on legal documents?

I'm a product manager for a web service and I have to work a lot with people from legal to write TnC, data privacy, etc.

Of course, legal likes to work with Word documents, but those can't really be used online. Right now, I've to convert the word documents to markdown and forward them to the devs, but conversion most of the times does not work properly and manual work is necessary all the time.

Did anyone already find a good way to handle those kinds of documents, so that legal can work as they are used to, but at the end we're getting sth. that can be used on the web?

Of course, showing a PDF would be an option, but it just doesn't look nice/integrated.
