Can file dowry case against my inlaws to recover my belongings

Hi, I am staying separate with my kid from my husband from last 10 months due to things not working between us. I am still not able to make up my mind for divorce but I need to recover my belongings( my car worth Rs. 7 lakhs & approx. 200 gms gold ornaments and few silver items) from him and his family which they are not ready to return. They claim I have taken everything along when I left their home. which is not true. I just want to understand can I first recover my belongings by putting a dowry and harassment case and then see If I want to divorce him. Request you expert advice.
