How can I stop a court ruling if the court case has shifted territory?

My ex -wife took me to court 2 years ago in Zurich and got a preliminary separation court order for alimony+ Visitation rights + child communication.
At the time I was forced to move out of Switzerland and now live in Bucharest

My wife instead of filing for the issuing of the divorce after the 2 yrs in Zurich she filed in Romania....yet the court order for alimony+visitation rights etc is running in zurich
I assume she did it as she does not want to pay me half her pension casa that i am entitled for looking after our child while she worked.

What is advisable for me to do under the circumstances?

You need a lawyer; so far as I understand if the action was started in Switzerland then you have to continue in Switzerland - you cannot change halfway through. This is why clever people start their divorce actions in countries that have favourable rules for them.

Usually I believe the Courts see it so: the process started in Zurich and it should continue in Zurich.

Before rushing off to an expensive lawyer, why not take your separation agreement to Zurich and ask them to continue with the divorce.

You have agreed on most things, so there is little more than a rubber stamp and ordering her pension fund to transfer half her assets to your fund and vice-versa.
