Every completed service ends in a sworn affidavit: who was served, the exact date and time, the address, a physical description of the person, how identity was confirmed, and the signature of the server. Notarized and filed with the court where the rules require it.
When a recipient is hard to reach, attempts are spread across genuinely different times of day and days of the week - not three tries on the same Tuesday morning - so a real pattern of diligence exists if substituted service is later sought. Each attempt is logged with timestamp and GPS.
What a server may do: attempt at home and at work, and where the rules allow, leave a copy with a competent adult, or post and mail with court permission. What is never acceptable: no trespassing into a locked residence, no impersonation, no threats, and no service by deception where it is prohibited.
