Your lawyer has I'll advised your parents to not to receive the summons in your name since you are non resident in India, but an Indian national, accused in 498 a. Now, the court may issue NBW against you that the moment you arrive in India, could be arrested (after the immigration or) during your stay in India. Don't try to fight with the Court in a foolish manner, instead send an application (attested by the Indian consulate in your resident country) to the concerned court with apology, to give another date for your appearance. Come and appear in the court accordingly. However LOC may not be issued against you. I can give you long lecture on this topic but have no time to spare for the people who disrespect our Indian courts.
