First, examine your lease agreement to determine if it addresses disputes between tenants. If it doesn't, the most secure approach would be to obtain a court order directing the distribution of the funds. You can either file a motion in the existing case or ask the attorney to provide a court order. Alternatively, you can seek a written agreement from both parties outlining the division of the security deposit. I recommend you speak with an attorney.
