If your user shall *write* and *not* *create*, you can remove all his write
permissions to that directory. This implies the file already exists.

If he must be able to create a file this is more complicated, you will
have to keep his write permissions at directory level, use the sticky
bit and find a way to quickly change the file ownership once it is created.

see chmod (2)
