I don't know for sure, but, yes, the divorce will be held until the pregnancy is finished. The courts want to make sure they get it all done at once.

Check with a doctor on whether a test can be done pre-delivery that is non-invasive. I don't think a court will order an invasive test.

Once the baby is delivered, you should have a court order ready to do an immediate DNA test.

I am confused - why on earth would you avoid a server? Living separated is much more dangerous to you financially than divorced. She now has legal rights to more support, etc. if she decides to be on limited work during this pregnancy. You are legally responsible for the medical bills she is going to incur, etc.

A legal separation is just as costly as a divorce - at least that is what I was told. So, I paid for medical insurance, liability insurance, etc for my ex for over 2 years. That was FAR better than waiting for him to drive drunk and hit a family and get stuck with that lawsuit.
