M v. B, 2026

The father filed a guardianship petition seeking appointment as the permanent guardian and permanent custody of the minor child.

The mother opposed the petition, contending that the father was unfit to have custody due to his alleged drug and alcohol use.

The mother stated that in 2020, while the father was asleep, she accessed his mobile phone and photographed WhatsApp chats, screenshots, internet searches and other digital material using her own phone.

The documents allegedly revealed conversations regarding the procurement of narcotic substances, drug-related communications, internet searches concerning drugs and an alleged relationship with another woman.

The father denied the allegations and disputed the source, authorship, authenticity and contents of the electronic material.

When the mother attempted to mark these documents before the Master Court, permission was refused on the ground that they involved the privacy of the father and third parties.

The mother therefore approached the Madras High Court seeking permission to place the electronic records on record in the guardianship proceedings.

The Madras High Court allowed the mother's application.

The Court held that the welfare of the child is the paramount consideration in guardianship proceedings.

It observed that material allegedly showing drug use, procurement of narcotic substances or association with persons involved in such activities may directly affect the assessment of a parent's fitness.

The Court held that such material cannot be excluded merely because it originated from private communications.

The Court clarified that the dispute was not simply between the father's privacy and the mother's desire to produce evidence, but involved balancing privacy with the child's welfare.

The Court emphasized that privacy remains an important constitutional value, but it cannot automatically override evidence directly affecting the safety and welfare of a child.

The Court observed that not every private communication becomes relevant merely because custody is in issue.

It held that only material having a real and rational connection with the child's welfare should be admitted.

The Court directed that the electronic material should be used only for the guardianship proceedings.

It further directed that confidentiality should be preserved by protecting third-party information and preventing unnecessary publication.

The Court held that the mother must establish the source, authenticity and context of the electronic records.

The father was granted full liberty to cross-examine the mother and raise all objections regarding admissibility and authenticity.

The judgment carefully balances the constitutional right to privacy with the best interests of the child, giving primacy to child welfare in guardianship disputes.

The Court clarified that privacy is not an absolute right and may yield where evidence is directly relevant to protecting a child's safety.

The decision recognizes the increasing importance of electronic evidence, such as WhatsApp chats and screenshots, in modern family litigation.

The Court avoided creating a blanket rule permitting unrestricted use of private communications by insisting upon a direct nexus between the material and the child's welfare.

By requiring proof of authenticity, source and context, the Court safeguarded against misuse or fabrication of electronic evidence.

The judgment also protected procedural fairness by preserving the father's right to challenge the evidence through cross-examination.

The ruling strikes an appropriate balance between privacy rights, fair trial principles, and the paramount welfare of the child.

The decision is likely to serve as an important precedent governing the admissibility of private digital communications in custody and guardianship proceedings.
