Child custody and guardianship laws in Bangladesh are primarily governed by personal laws based on religion, with some overarching civil laws applicable in specific cases. The legal framework aims to protect the best interests of the child, but the application can vary based on the religious background of the family. For Muslim families, child custody is governed by Islamic law principles as interpreted in Bangladesh. The concept of 'hizanat' (custody) gives preference to the mother for custody of young children, typically until boys reach seven years and girls reach puberty. After this age, custody generally transfers to the father. However, courts have the discretion to extend the mother's custody if it serves the child's best interests. The Guardian and Wards Act 1890 is also applicable, allowing courts to appoint guardians for minors. In Hindu law, which applies to Hindu families in Bangladesh, there is no specific provision for child custody. The father is considered the natural guardian of the child. However, courts often consider the welfare of the child as paramount in custody decisions, which may result in custody being granted to the mother if it's in the child's best interest. For Christian families, custody matters are generally decided based on the principle of the best interests of the child, as interpreted by the courts. The Divorce Act 1869, which applies to Christians, allows courts to make orders regarding custody of children in divorce proceedings.
