Hi
Step 1:
1) The courts have granted you an anticipatory bail and the procedure is that you and your parents meet the I/O and
a) carry with you the original copy of the interim anticipatory bail and
b) execute the personal bond for a sum of 25000 each
c) and with one surety (for each person ) for a like sum (i.e Rs25000 for each person)
2) Upon completion of above the I/O will release you on bail and this will continue till the disposal of your regular bail petition.
Step 2
3) Upon hearing of your main bail petition (which is a mere formality given that you already have an AB), the courts will grant you a regular bail till the disposal of case
4) In accordance to law, there is nothing in s.438 to suggest that the order of anticipatory bail shall be effective up to a particular stage or till the filing of the challan.
5) As soon as a person is enlarged on bail on the directions of anticipatory bail order, It would be deemed by implication as if the bail was granted under s.437.(1) that the bail shall be effective till the conclusion of the trial , unless it is cancelled by the court taking action under s.437(5) or under s.439(2) of the Code on the grounds known to law and filing of the challan in the court is by it self no ground to cancel the bail.
6) So all you need to do complete the formalities of Anticipatory bail and get the bail converted to regular bail at the time of main bail petition.
Step 3:
7) Bail pertains to your personal liberty and has nothing to do with the facts of the case.
8) In all likelihood(as is the case with plethora of 498A cases all over india and depending on merits) your parents will be excluded in the charge sheet and it is also likely that your 498A will be dismissed at the very earliest.
So no worries.
