From my understanding, one party (the plantif), will get the original FJ, while the other party, will get another copy.
Not sure if it's certified true copy though. Not sure if via email? Since usually is post mail in the past. Maybe is email now due to covid? You may need to check with law firm for it.
But I think the period depending on law firm/court etc. May not be exactly 3 months. Can be earlier or later.
