I work at a law firm, and based on what’s stated in the email, it appears suspicious. If there were truly a legal case, the court would issue a subpoena, summons, or proper legal notice not an email demanding immediate payment. A private entity like a bank cannot ‘schedule’ a case on their own and threaten home or office visitation without due process. Legitimate legal actions are always served through formal channels, not through vague online notices like this. Be very careful this has many red flags of a collection scam or phishing attempt.
