In New York you can now use Facebook to be social and serve your spouse with divorce summons. A Manhatten Supreme Court judge just ruled that you can do just that on Facebook now.
When you serve a divorce summons to your not so significant other they will get a notification once a week for three weeks. After that the divorce will go through if they acknowledge or refuse to respond. This sets a precedent in New York now that you no longer have to track the person down and deliver the notice in person. This should make things easier for those who would have had a hard time tracking someone down that was dodging people attempting to serve papers.
