FIR quashing steps & process before 2nd motion

We agreed and mentioned in the MOU that we will File the FIR quash before 2nd motion of Mutual divorce. And first motion is completed and 2nd motion is scheduled for the 1st week of April. Now, my Advocate is suggesting to file the FIR Quash after the 2nd Motion and he will file the quashing with the Divorce decree. Otherwise, the High court can either reject the application or the case dates will be extended as if we go before the 2nd motion then the next day of the hearing will be very late. And the Quashing case will be extended and also there is a risk of the High court can levy the fee (penalty). I am looking for an honest response. What should be the best action to be followed? And suggest whether above points told by my Advocate are true?
