Did this recently but there are cautions:
First you have to make sure that you restrict "write" access appropriately, second where for example a document register is on Google Drive and you may need to keep a copy of all versions, you need a foolproof way to do this since usually, any edit to the "master" document on Google drive instantly updates it and you lose info on the previous version.
Google drive also ignores any password protection in Microsoft Excel documents, maybe the same for Word documents, I never got to test that out.
A good tip if you have an excel spreadsheet you want to edit but has a password lock, and you don't know the password, is to upload/convert it to Google Sheets since as I stated above, Google Docs doesn't recognise Microsoft's basic security measures on documents........
