An Unusual deposit in the name of the child

Dear Sir, We are living separated for the past 3 years and a divorce case has been going on for the past 2 years. I had filed the divorce and the court has allocated 6 months before the next hearing. There is no maintenance request filed by me. Our marriage was full of abuse and cruelty and harassment. I tried my best but could not reconcile and just want to break sir, When we were together there were no savings which were being made as he was a regular job changer and behaved in a mentally abnormal way as well giving torture to me and my son. In the last hearing he sought to open a new bank account for my son and I shared the account number with him. Since the last 30 days there is a disproportionate deposits being made in the said. A sum of Rs. 30 lakhs has been deposited. Sir, I am not sure what is the intention behind this or is this a new way to harass me. Looking at the amount, this is again not a normal behaviour for a person. Is there any legal hurdle which I may face because of these deposits. Not sure by making this he is trying to influence as if he was taking care of me and my child atleast to the minimum. Need your advice on this Sir. Thank You
