yes mrs mk, you are right. it is victimisation and harassment. you may want compensation on it.
for a male, getting divorce is approximately a night mare today, therefore, many males doing such conspiracy against their wife.
while the facts are contradictory, he will get in trap easily at court. you may charge him for purjury and defamation. it will be a separate case, other than divorce.
you are right to say that "if the wife says that the divorce proceedings were planned to escape from 498a filed". it happened several times. you will find here such cases.
you must attend the court, otherwise the case may be ex party in faviour of him. when you have received the court summon (not his pleader's notice) you must have got a date for appearing the court; on that day you must attend the court. you will get a chance for filling a written statement. on your written statement, you write whatever you like, and also pray for dismis the petition of him. ask for maintenance by a seperate petition u/s 24 of HMA - it is your right. file it first. after getting maintenance, file written statement. if your maintenance petition is their, the court has to dispose of this petition at first, then only the court can go to the next stage.
