I would like to know when and when not to use 's.
1- Contacts information?
2- Clients file?
3- Clients insurance?
Thank you !
For example, if the file belongs to the client, I will put 's, but if it's a client file (or clients files) as a description of what kind of file it is, I won't put 's, is that right ?
If it belongs to the client then use client's file.
