Adultery by a parent does not by itself decide who gets custody of a child in India. The court decides custody by asking one question: what arrangement is in the welfare and best interest of the child. Adultery is a ground for divorce and a relevant circumstance, but it is not an automatic disqualification, and a parent who has been unfaithful can still be found the fitter custodian on the evidence.
Adultery is no longer a crime
Until 2018 adultery was a criminal offence under section 497 of the Indian Penal Code, 1860. The Supreme Court, in Joseph Shine v. Union of India (2018), struck that provision down as unconstitutional. Adultery survives only as a civil wrong, which means it remains a ground for divorce and can be weighed in matrimonial proceedings, but there is no criminal case to be made out of it and no imprisonment. This matters for custody because allegations of adultery are often pleaded to paint the other parent as immoral. The court treats them as one circumstance among many, not as a finding that decides the child's future.
The one test that governs custody
Custody in India is decided on the welfare of the minor, and that principle is written into the statutes, not merely quoted in judgments. Under the Hindu Marriage Act 1955 the court can pass orders about the custody, maintenance and education of minor children in any matrimonial proceeding; under the Hindu Minority and Guardianship Act 1956 the welfare of the minor is the paramount consideration when a court appoints or declares a guardian, and it can override the ordinary rule that the father is the natural guardian. Under the Guardians and Wards Act 1890, which governs custody outside a matrimonial petition and for communities whose personal law does not fix the position, the court is guided by what is for the welfare of the minor. The family court acts like a guardian of the child, not an umpire rewarding good spouses and punishing bad ones.
This is why a party can be found guilty of the matrimonial wrong and still be given custody. The two enquiries run on different tracks. The divorce turns on whether adultery is proved; custody turns on the child. Conflating them is the commonest mistake in a self-drafted custody application.
What the court actually looks at
When adultery is alleged, the welfare enquiry does not stop at the allegation. The court weighs a cluster of practical factors, and the moral conduct of the parent as a spouse enters only through those factors.
| Factor the court weighs | How a parent's adultery bears on it |
|---|---|
| Day-to-day care and stability | A settled home and consistent routine usually help the parent who provides them, whatever the marital history. |
| The home environment offered | The court examines the relationship and the character of any new partner, and whether the arrangement is stable or acrimonious. |
| Emotional and psychological harm to the child | Exposure to open conflict, neglect or an unsafe setting weighs against a parent more than the adultery itself. |
| Age and sex of the child | Young children, and in particular a child under five, are usually placed with the mother by reference to their needs. |
| Child's own wishes | A child old enough to form an intelligent preference is heard, though the preference does not bind the court. |
| Capacity to provide education and health care | School continuity, medical care and financial ability are practical welfare factors. |
A stable, responsible arrangement tends not to be disqualifying merely because it began in adultery. An unstable or openly hostile one will weigh against a parent regardless of the marital facts. The question is not whether the parent was a faithful spouse but whether the child is likely to be harmed.
How adultery is proved in a custody proceeding
Adultery is rarely proved by direct evidence, because the act is private. Courts usually draw the inference from a combination of circumstances that together leave no other conclusion: telephone and messaging records, travel or hotel records, the evidence of a witness to the parties, and admissions. Because the standard is a civil one in matrimonial matters, the court looks for conduct that is inconsistent with fidelity rather than for an eyewitness.
For custody the proof is often beside the point. Even where adultery is established, it is the effect on the child that the court examines, so a party who spends the case proving infidelity and says little about daily care has proved a fact the court will not act on. Evidence of the home offered, the child's schooling, routine and medical attention does far more work.
Custody, divorce and maintenance are separate questions
It is common for all three to be live at once, and each is decided on its own footing. Adultery is a ground for divorce under the personal law, and it can be a relevant factor in an application for maintenance, though a spouse is not disentitled to maintenance merely because adultery is alleged. Custody is decided on welfare. A party may therefore succeed on the divorce, be ordered to pay or receive maintenance, and still lose custody, or the reverse. Keeping the three apart stops a strong case on one from being weakened by the odds on the others.
Married but living apart: what still applies
A spouse who begins a relationship while still legally married does not commit a crime after Joseph Shine, but remains a married person in law until the decree of divorce is made absolute. That has two consequences. First, the relationship can be pleaded as adultery, which is a ground for divorce and is relevant to maintenance. Second, if the matter reaches the family court, the court may scrutinise the setting the child is being raised in, even though it will not treat the new relationship as automatically disqualifying. For parties married under the Special Marriage Act 1954, adultery is one of the statutory grounds for divorce, and the court can pass custody orders for the children of that marriage in the same way.
For Hindus, the custody position is governed by the Hindu Marriage Act 1955 and the Hindu Minority and Guardianship Act 1956. For communities whose personal law provides its own custody rules, such as Muslim personal law, the courts apply those rules but still test them against the welfare of the child, which the Guardians and Wards Act 1890 makes the governing consideration where it applies. The practical result is the same in every forum: the welfare of the child is the deciding weight, and no parent's marital conduct is allowed to defeat it.
Interim custody and visitation
Most custody battles begin long before any final order. In a pending matrimonial case the family court can pass an interim order on custody, maintenance and visitation, and it is common for the child to remain with one parent while the other is given defined visitation, sometimes in person and sometimes by video call. The court is reluctant to disturb an arrangement that is working and harming no one, because a young child's routine carries its own welfare value. An interim arrangement is not final: changed circumstances can be brought back before the court.
Where and how a custody case is brought
In West Bengal, custody is decided by the family court where an application can be made within a pending divorce or judicial separation proceeding, or by the civil court under the Guardians and Wards Act 1890 where there is no matrimonial proceeding. Cases arising in Kolkata and adjoining districts sit at the Family Courts and, where a guardianship application is filed, at the City Civil Court at Kolkata or the District Court of the district concerned.
The petition sets out the facts, the alleged adultery or other ground, and, most importantly, a concrete case on the child's welfare. The evidence expected is described in documents for a child custody case, and a ready draft can be seen in the child custody petition format under the Guardians and Wards Act.
Building a claim on welfare, not on blame
A party who pleads adultery as the centrepiece of a custody case usually finds the court uninterested in the marital fault and very interested in daily care. Records of schooling, medical attention, living arrangements and the child's routine do more work than character allegations. If your matrimonial proceeding is linked to a divorce on the ground of adultery, note that the two issues are decided on different footings: the divorce turns on whether adultery is proved, while custody turns on the child. For a matter that turns on your own facts, a short consultation is the quickest way to see which way the welfare factors point, and there is one on offer at the free consultation page.
