Need urgent advice on divorce filing

I guess you know you must be seperated for a year first.

yes, we know that. Please advice on the 2 issues.

My spouse and I have mutually agreed to divorce and we want to self file, since we have no kids, or any property together. We have picked up the sample divorce papers from the courts but have some queries:

1.Do we have to do the service through the courts or is there another way of serving divorce papers on each other?

Any extra information about how a spouse can be served expeditiously will be appreciated.

2.How long does it take from the day of service to the day the judge approves the divorce assuming no issues are raised by the defendant?
