<human>: Give me the gist of the text in a nutshell

My roommate and I lived together for around two years, had a good living arrangement, and are still friends.  She moved in with her boyfriend at the end of the lease, and we both moved out to different places.  The problem I have is that the former landlord is withholding a good amount of money (about 700 dollars) from our security deposit, most of which I think are things he can't legally charge for.

The biggest item (approximately 300 dollars), is for repair to a sink and mirror that were in my former roommates room.  My roommate swears it was damaged when we first moved into the place, but she never notified the landlord about it.  In her defense, it's a pretty small crack, and if I had been living in that bedroom I might not have reported it either.  If she had damaged it, I would have no hesitation about making the repair come out of her half of the deposit.  But, on the other hand, I think the landlord is trying to screw us and I don't think she should be charged at all.

We haven't discussed it directly, but as of now I'm pretty sure she expects us to split the cost since she said something along the lines of being charged 350 (half of the 700 dollar total).

Any ideas on how I should handle this.  Should I split the cost of the sink with her, or should she be on the hook since she didn't report it?  Also, anyone ever have luck getting a landlord to reduce charges on things they shouldn't have been charging for (normal wear and tear kinds of things).
<bot>: Former landlord is charging for a cracked sink (in my roommates room) that I don't believe my roommate broke.  Should she have to pay the charge for it, or should we split it?
