1. Shall I continue with contested petition 2yrs back
or withdraw my petition and file a new MCD as my advocate suggested?
Since you have already filed the divorce case and stated to have waited for almost two years, it is better not to go for compromise or one time quit settlement,because they now came to know that it will not be possible for her to comeback to India and contest the case, they just want to make some quick money out of the situation taking advantage over your urgency or helplessness. First you change your lawyer because he hasn't done any favor to you, in fact the divorce case what you have filed has almost come to a final stage i.e., exparte and evidence thereon after newspaper publication for serving the summons to her by substituted service. So Better go ahead with present divorce petition itself instead of having a wavering mind .
2. Is it possible without respondent (father will attended) getting MCD?
Her father can sign the papers for the first time but she has to be present for the second motion to give her evidence before the court in person. There is a risk in it that if she claims that she has not executed a power of attorney deedat all and she never gave her consent for divorce, then the entire process will start from beginning.
3. Suppose after i withdraw my contested petition, they are not ready to give MCD what will happen to my previous petition? can i request to re-consider?
Anything can be possible. If she withdraws her consent at the last moment, then you will stand losing your valuable time, money and energy as well as you will be put to a greater insult, further you have to look for fresh grounds for filing a divorce against her. Dont take any decision in a hurry, take time and take wise decision patiently.
