Abondening of wife by her husband

1.My niece is married to an Military officer for last 4 years. Due to continued mental harassment she came to stay with her parents house in Nov 21 as he used to humiliate her and they did not speak to each other since Sep 21. 2.After approx one month in Dec 21,when she went back to her house she was not allowed to go to her house at the behest of her husband since her husband was out of station. She was told that house is locked which was not correct as keys were with the servant who was present in the house. 3. My niece had only brought few clothes of her. She left all her valuables, jwellery, cash in the bedroom almirah which was locked. 3. In Jul 22 her husband was transferred to field area. He sold off all house hold expensive items like car, furniture and electronic items. Other items he shifted to his father's house. 4. My niece did not go there as she came to know that her husband has siphoned off her jwellery and other valuables. 5. He opened the lock of her almirah in presence of few departmental commitee (who are his colleagues). Commitee videographed the and made list of items recovered. He kept her personal belongings in the department store House. He went to new place of posting. Department is now asking my niece to collect her stores. 6. My niece is not interested in collection of stores without her husband's presence. 7. What legal action can be initiated against him. Thanks in advance
