Good Day
I am preparing requirements document and separated the use cases from the requirements. I want to find out what document can I now use to store the business cases
If you just want to do it in MS Word, search for a template online. Lots out there. Other way is to use some kind of tool. Enterprise Architect (sparxsystems.com) that I use caters for use cases.

Lots of other tools will cater for it too I expect
