An out-of-the-blue 'court summons' email with an attachment or link is often phishing. Paste the text for an instant read.
Courts usually serve a summons in person or by mail; it has a real court name, case number, and response deadline. A random email with a 'view summons' link is a classic phishing/malware vector.
Don't open attachments or click links. Verify by contacting the named court directly (find its number yourself). If real, note the deadline and get advice.
Some courts use electronic service in active cases, but an unexpected email with a link to a 'summons' is usually phishing. Verify with the court directly before clicking anything.
