If wife doesn't want to live with in-laws ,how to file a divorce case ?

Yes'your wife can file a criminal complaint alleging dowry'related cruelty because Section 85 (cruelty by husband or his relatives) of the Bharatiya Nyaya Sanhita (BNS) and the Dowry Prohibition Act permit such complaints, but mere refusal to live with your parents or isolated workplace rumours will not automatically satisfy the statutory definition of cruelty (Section 86 BNS) unless there are specific facts showing harassment or dowry demands; courts and the new procedure law treat such complaints seriously but will quash or curb proceedings that are vague, omnibus, retaliatory or mala fide. See BNS (general text and Section 85/86) for the substantive offence and definitions: Bharatiya Nyaya Sanhita / BNS (Ministry of Home Affairs) [https://www.mha.gov.in/en/commoncontent/new-criminal-laws] and Section 85/86 commentary [https://www.apnilaw.com/bare-act/bns/section-85-bharatiya-nyaya-sanhita-bns-husband-or-relative-of-husband-of-a-woman-subjecting-her-to-cruelty/] [https://www.apnilaw.com/bare-act/bns/section-86-bharatiya-nyaya-sanhita-bns-cruelty-defined/]; procedural protections (arrest/bail/quash remedies) are governed by the Bharatiya Nagarik Suraksha Sanhita (BNSS) (see BNSS text) [https://www.mha.gov.in/en/commoncontent/new-criminal-laws] and evidentiary rules by the Bharatiya Sakshya Adhiniyam (BSA) [https://www.mha.gov.in/en/commoncontent/new-criminal-laws]. Key authorities: the Supreme Court's safeguards on arrests and preliminary inquiry in matrimonial/dowry cases (Rajesh Sharma v. State of U.P., guidelines on arrests and family'welfare inquiry) [https://indiankanoon.org/doc/182220573/], the principle that courts may quash proceedings where allegations are vague, omnibus or mala fide (State of Haryana v. Bhajan Lal) [https://indiankanoon.org/doc/1033637/], and the recent ruling quashing a retaliatory dowry FIR where allegations were generalised (Dara Lakshmi Narayana v. State of Telangana) [https://indiankanoon.org/doc/93461652/]. If accused, consider prompt legal steps (preserve evidence, seek anticipatory bail under BNSS and move to quash if allegations are vague).
