Immigration Bond refund Other Immigration Law

I posted a bond for my friend a couple years ago and he was released, however the case for which the bond was posted got terminated last year because he has a prior case pending of which he appealled to High Court and currently awaiting a decision. Can I apply for a refund of the bond since the case related to the bond has terminated? If so, do I need an attorney or can I apply on my own if I have the bond receipt and bond agreement? How do I apply or where can I go for more information?


Thanks.
