I gave my roommate who sublet the room to me a move out notice. On the notice, I stated that "please make the security deposit available within 21 days after I move out and I will pick up the deposit in person". I also sent the notice to her via certified mail. But I did not put down my new address on the envelope, in stead I used the old address, the address from where I moved out and any returned mails will be forwarded to my new address by USPS. I don't want to expose my new residence and the people living there. So, in case I have to sue her for not returing the security deposit in time, would the missing forwarding address be a reason for her to win?
