Quick answer
Use emergency services for immediate danger and seek prompt advice about emergency court relief.
Do now
Describe specific recent facts, dates, injuries, threats, and locations. Preserve evidence safely and obtain medical help where needed. Bring all existing orders and disclose other pending cases to the court or lawyer.
Watch for
Do not delay emergency help to collect perfect evidence. Emergency relief is temporary and has legal standards; exaggerated or unsupported allegations can harm the process.
