There is a growing trend to allow Service (delivery) of Pleadings through Facebook. This Brooklyn Judge, on the facts presenetd, did not allow this.
The Brooklyn Judge declared:
“Granting this application for service by Facebook under the facts presented by plaintiff would be akin to the court permitting service by ‘nail and mail’ to a building that no longer exists,”
(Factually, the Court declared that he supposed Facebook profile for the husband was inactive, with the most recent posting was from 2014.)
The Court stated:
"[The Wife] has failed to sufficiently authenticate the Facebook profile as being that of the defendant and has not shown that, assuming arguendo that it is the defendant’s Facebook profile, that defendant actually uses this Facebook page for communicating,”
