Dear Rohit,
Congrats on clearing Bank PO Exam!
Notwithstanding your marital troubles, passing the competitive exam is no easy task. This shows that you have great ability to concentrate on your career and domestic troubles do not put you in emotional turmoil. Kudos to you! Keep it up!
At the time of joining government or semi-government organisations, there are lot of forms to be filled. Amongst these includes declaration on court case against you. Do not hide the fact that court case is in progress against you. Formal declaration at the time of joining will keep the things in proper perspective.
Nevertheless, if you are respondent then court hearing will take place during your training also. Is your attendance mandatory at the court that you please check with your lawyer. Secondly, even after completion of the training, you could be posted in a city other than where court case is going on. In that case, how will you be able to attend the court case? This also could pose challenge to you.
In the meanwhile try to work out marital reconciliation. If this does not succeed, try for mutual divorce. This will settle your all the problems to the rest.
All the best!
Dinesh Divekar
