Hi Kumar, I'm Adv Niharika and this is my take on your query.
A- you must discuss with your lawyer to proceed ex parte against the defendant under Order 9, Rule 6, CPC.
As it is for you to expedite your case proceedings. If you keep waiting for the other party to appear. The judge will be of the opinion to wait till both the parties arrive but you must take the process in your hands as far as possible.
B- settlement of maintenance (permanent alimony or monthly) takes place after contesting the entire case, when the judge has heard both the parties and their arguments, then the Court comes to a stage to determine maintenance. This can take a long time. Until then Court might grant interim maintenance.
I will advice you to settle one time outside of court. Take a competent lawyer who has enough influence to get people on table and to a mutual decision without getting into judicial proceedings.
I'm attaching a relevant link, wherein the experts are discussing the on the same topic.
i hope this information is fruitful to you.
