Of you file a claim and then do not appear in court the Judge may dismiss the matter for failure on your part to appear... An attorney can not appear on your behalf without you present..
However, depending on the venue it may be possible to have you appear by phone.
It would not look good for you to not show up.
READ THIS BEFORE CALLING OR EMAILING ME: I am licensed to practice before the state and federal courts in Virginia. We have not established an attorney-client relationship unless we have a signed representation agreement and you have paid me. I give a 100% effort to get you on the right track with your issue. Sometimes that means legal educational information, sometimes that means counseling and non-legal guidance. You should speak with an attorney to whom you have provided all the facts, before you take steps that may impact your legal rights. I am not obligated to answer subsequent emails or phone calls unless you have hired me. I wish you the best of luck with your situation.
