What an offshore legal assistant is
The assistant works from a country many hours away, inside your systems, on a process your attorneys have written down. Each location brings something different.
The Philippines is on UTC+8 with no daylight saving, 12 or 13 hours ahead of US Eastern, and has a large English-speaking back-office workforce. India is on UTC+5:30 and also works in English. Egypt is on UTC+2, or UTC+3 in summer, and adds Arabic alongside English.
The assistant either works their own daytime, which is your night, or a shift aligned to part of your day. Either way, far fewer hours overlap with your attorneys than with a nearshore team.
