Roommate Refuses to Return Security Deposit Despite Payment Agreement

[Star810]

My question involves landlord-tenant law in the State of: Maryland

Hi. I was living with a friend in Maryland for 12 months. I decided to move out and she decided to stay after 12 months. Our lease was automatically renewed for another year and the Apartment Complex refused to give to give me my portion of the security deposit back ($900!!!!). In order to get out of my lease I did an assignment to a new tenant to take my place on the lease.

When we parted ways I drafted a payment plan that I, my friend, and the new tenant agreed to in order for me to recoup my security deposit. I forgot to get it notarized, but the plan lists the days and the amounts in which each payment was due. I also dated and initialed when each payment was received. Now my ex-roommate/friend has decided not to talk to me and has not payed the final balance due ($450) as the agreement stipulates. I have reached out to her numerous times and has even attempted email. I think I have exhausted all avenues of communication and want to sue her in small claims court. I have no faith in her that she will give me the rest of my money. I completely relied on our written and oral agreement to my own detriment. I had no reason to believe that she would renege on our previous agreement because she paid the previous times. The payment plan was over the course of 12 months and the statute of limitations is 3 years in Maryland, so I don't think I will be time-barred. Do you think my complaint would be successful?

Why wouldn't it be? You expect that they'll deny the agreement? Claim to have made the payment? Some other defense?
