Courts usually start with a summons and move to an arrest warrant only if your presence cannot be secured by a simple notice, looking at factors like seriousness of the offence, risk of absconding, past non‑appearance, and how easy it is to serve you. The safest response for an accused is to contact a good criminal lawyer immediately, share all documents, follow advice on appearing or seeking bail, strictly attend all court dates, and let the lawyer handle any request to cancel or modify a warrant or to challenge defects in the process.
