The short answer
For a child custody case in India you need the child's birth certificate, the marriage certificate, proof of your identity and address, proof of your income and residence, the child's school and medical records, and a petition supported by an affidavit. Which documents carry the most weight depends on the court and on who is claiming custody, but the welfare of the child is always the deciding question.
The list below is the practical set a court expects to see, grouped by what each document proves. A file that is complete when it is first presented saves months, because a defect in the pleadings means a fresh date and a fresh delay.
Which law governs custody
Custody can arise in three ways, and each has its own statute. Where there is no matrimonial case and one person seeks to be appointed guardian, the Guardians and Wards Act, 1890 applies, and Section 17 of that Act requires the court to be guided by the welfare of the minor. Where the parents are Hindu, the Hindu Minority and Guardianship Act, 1956 also applies, and Section 6 of that Act provides that custody of a child below five years is ordinarily with the mother.
Where a divorce or judicial separation case is already pending, custody is decided within that case. Under the Hindu Marriage Act, 1955 this is dealt with by Section 26, and under the Special Marriage Act, 1954 by Section 38. In all three settings the paperwork overlaps heavily, so the documents collected for one purpose usually serve the others.
The welfare principle runs through all three statutes. Whatever the label of the case, the court is not deciding a contest of rights in the abstract; it is deciding what arrangement will best serve a child who has no say in the litigation and whose interests the court must protect itself.
Core documents about identity and the marriage
- The child's birth certificate, issued by the municipal registrar or the panchayat. This is the single most important document, because it establishes the child's age, parentage and place of birth.
- The marriage certificate, or the registration record, to show the legal relationship between the parents.
- Proof of identity of the person claiming custody, such as Aadhaar, a voter card, a passport or a driving licence.
- Proof of address, such as a rent agreement, a utility bill, a ration card or an electricity bill in the claimant's name.
- The school admission record or, for a younger child, the immunisation card, to demonstrate continuity of care.
A birth certificate that names only the mother can raise questions where the father seeks custody, so a corrected or re-issued certificate should be obtained if the details are incomplete. The local registrar handles corrections, and the process is separate from the custody case itself.
Where the birth certificate is missing altogether, it can be obtained from the registrar who maintains the record, and in Kolkata this is handled through the municipal corporation's registrar of births and deaths. A certified extract is enough for the court file.
Documents about the child
The court is asking one question: what arrangement serves the child best. Documents that show the child's daily life are therefore valuable.
- School records: admission form, report cards, attendance, and letters from the school if the child's routine has been disrupted.
- Medical records: the immunisation history, prescriptions, and any report of illness or treatment.
- Recent photographs of the child at home and at school, which are often part of the file though not decisive on their own.
- Details of any special needs, including therapy or tuition, and who arranges and pays for them.
For a child who is old enough to express a preference, the court may speak to the child privately, and the child's wishes are given weight according to age and maturity. This is an exercise the court conducts itself and it is not driven by documents filed by the parties.
A child's routine is the best evidence of stability. A school that confirms regular attendance, or a doctor who confirms continuing care, speaks more plainly than any assertion in an affidavit.
Financial and residence documents
Custody and maintenance travel together. To show that you can provide for the child, and to support a claim for maintenance where the other parent should contribute, keep the following ready.
- Salary slips, the income-tax return, or the accounts of a business.
- Bank statements for the last six to twelve months.
- Proof of the home where the child would live, such as the rent agreement, the property document or the utility bill.
- Evidence of expenses already met for the child, such as school fees, medical bills and transport.
- If the other parent already pays maintenance under an order, a copy of that order.
Income documents serve two purposes: they show the court that the claimant is able to care for the child, and they help fix the amount the other parent should pay. A court usually takes into account the income of both parents and the actual needs of the child.
The court does not compare the parents' wealth to pick a winner. It asks whether the child's material needs will be met and whether the arrangement is stable. Income documents serve that question, not a contest of status.
Evidence about the child's welfare
Beyond the formal papers, the court looks at the child's surroundings and stability. Supporting material on this point can include affidavits from relatives, neighbours or teachers who know the child's routine, and a record of who has been the primary caregiver.
Where there are allegations of neglect, addiction or violence in the household, the court will expect documentary support: a medical report, a police complaint, or an order passed under the Protection of Women from Domestic Violence Act, 2005. Bare allegations carry little weight; the court deals with proof.
A court may also order a welfare report through a child-welfare officer or an officer of the court, and in some cases it interviews the parties itself. The purpose of all this material is the same: to help the judge decide where the child will be safe, settled and cared for.
Court papers and where to file in West Bengal
The pleadings themselves are documents. A custody case is started by a petition or application setting out the facts, the relief sought and the basis on which the court should decide. That petition is supported by an affidavit verifying the facts, and, where an advocate is engaged, a vakalatnama is filed.
The pleadings should state the relief sought precisely, whether it is permanent custody, interim custody, or guardianship with defined visitation. A vague prayer gives the court nothing to grant and invites an amendment later.
In West Bengal, custody matters connected with a pending matrimonial case are heard by the Family Court at Kolkata or the Family Court at Alipore, and by the family court of the district where the case is filed. A guardianship petition under the Guardians and Wards Act, 1890 is filed before the District Court having jurisdiction, and certain guardianship matters concerning persons within Kolkata may come before the Original Side of the Calcutta High Court. The court fee is nominal and is set by the current schedule, so the exact figure should be confirmed at the time of filing rather than assumed.
| Document | Why the court wants it |
|---|---|
| Child's birth certificate | Age, parentage and place of birth |
| Marriage certificate | Relationship between the parents |
| Identity and address proof | Who the claimant is and where the child will live |
| School and medical records | Continuity and stability of the child's care |
| Income and bank documents | Capacity to provide, and fixing maintenance |
| Petition and affidavit | The claim and the facts the court must decide |
What the court weighs most
Across these statutes the court applies the same test: the welfare of the child. It looks at who has been the primary caregiver, the child's age and schooling, the stability of each home, the ability to provide, and the child's own wishes where the child is old enough to express them. No single factor decides the case, and the court is free to depart from the ordinary rule where the facts require it.
Because the test is the child's welfare, a parent who has not been the primary caregiver can still succeed by showing a stable and suitable home. Equally, the parent with the higher income does not win automatically, and a court will look at the quality of care rather than the size of the balance sheet.
Building the file before you file
Most custody cases are won or lost on preparation, not on the hearing day. An advocate sorts the documents into three bundles: the child's records, the financial records and the pleadings. That structure lets the court see at a glance what the child's life looks like and what each parent can offer. If the custody question follows a divorce, the same file also supports claims for maintenance and interim custody, and it pays to see the matrimonial position as a whole.
