An accident case

Ours is a four wheeler. It met accident with one bike. In that bike a husband,wife and 3 yr child was there. Not only that a huge load was there in d bike which was extending outside. As we are overtaking because of their negligence the bike's handle slide on d side of car bcz instead of moving their bike apart they moved so close and they did not deccelerate also. At that time the child was injured only small injury. Bt my husband got nervous as it was d first accident. He helped them to admit the child in hospital. But they behaved rudely and they said that they need money and begged before as not to register case. Bcz of our emotion v gave 10000 r.s at that time. At that time they said that plz don't take case bcz that person needs to go to some gulf country soon. Bt after some days one of their relative called us and said to give more money. As v disagreed against that they said that they will take case. And they registered against us. It was said that the hearing will be within 5 yrs. So we waited for that but unfortunately v were not there at home wen the post for first hearing was put. So now v got the paper and it was written pic 279 and 337 and calender case. Now v r afraid that is there any imprisonment. What to do?Plz give ur valuable suggestions.
