This is a genuinely important and frequently misunderstood question, and I want to reassure worried parents right away: turning eighteen does not automatically cut off a child's right to maintenance in every circumstance, even though eighteen is generally recognised as the age of majority in India. Whether maintenance in Mumbai can continue to be claimed for a child who crosses this threshold during pending divorce or maintenance proceedings depends on several factors, including the child's gender, marital status, educational circumstances, and whether the child suffers from any physical or mental condition affecting their ability to be self-sufficient — and Indian law provides meaningfully different answers depending on which of these factors applies to your situation.

Let's start with the general statutory framework. Under Section 20 of the Hindu Adoptions and Maintenance Act, 1956, a Hindu is under a legal obligation to maintain their legitimate or illegitimate children during minority. Crucially, however, Section 20(3) of the same Act extends this obligation further for daughters specifically, stating that the obligation to maintain an unmarried daughter continues so long as she remains unmarried and is unable to maintain herself out of her own earnings or other property, even after she has attained majority. This means that for an unmarried daughter, turning eighteen during pending proceedings does not automatically terminate her right to claim maintenance — if she remains unmarried and cannot support herself, whether because she is still pursuing education or for any other genuine reason, the obligation to maintain her continues.

For sons, the position under general Hindu law maintenance principles is that the parental obligation to maintain typically continues until the son is able to maintain himself, which in practice often aligns closely with the completion of his education or attainment of independent earning capacity, though this is somewhat less explicitly codified for sons under Section 20 compared to the specific protection extended to unmarried daughters. Courts have nonetheless recognised that where a son is still pursuing higher education and genuinely dependent on parental support at the time he turns eighteen, this dependency does not simply evaporate on his eighteenth birthday, and maintenance claims can reasonably continue to cover reasonable educational expenses until he completes his course of study or otherwise becomes self-sufficient.

There is a further and very important protection under Section 20(3) itself: the obligation to maintain a child, whether son or daughter, extends beyond the age of majority without any time limitation where the child suffers from any physical or mental abnormality or injury that renders them unable to maintain themselves. If your child has a disability or medical condition affecting their capacity for self-sufficiency, the ordinary age-based cutoffs simply do not apply, and maintenance can be claimed and continued indefinitely for as long as this dependency genuinely persists, subject of course to the paying parent's capacity and the specifics the court considers appropriate.

Now let's address the specific procedural question embedded in your query: what happens when a maintenance or divorce proceeding is already pending, and the child turns eighteen while the case is still working its way through the Family Court? The good news is that Indian courts have generally taken a practical, welfare-oriented approach here rather than a rigid, mechanical one. If the maintenance application or claim for the child was validly initiated while the child was still a minor, courts do not typically dismiss the claim outright simply because the child crosses eighteen before the proceedings conclude — particularly where the child remains an unmarried daughter, or a dependent son still in education, or a child with a qualifying disability. Your advocate can, and should, specifically bring to the court's attention the continuing dependency and the applicable provisions under Section 20(3) to ensure the maintenance claim is properly considered on its full merits rather than treated as automatically extinguished by the passage of the child's birthday during litigation.

If you are pursuing maintenance under the criminal law route rather than, or in addition to, matrimonial proceedings, Section 144 of the Bharatiya Nagarik Suraksha Sanhita, 2023 — the successor provision to the erstwhile Section 125 of the Code of Criminal Procedure, 1973 — provides for maintenance of children generally until they attain majority, but importantly also extends this protection to unmarried daughters even after majority if they are unable to maintain themselves, and to children of either gender, whether minor or major, who are unable to maintain themselves due to physical or mental abnormality or injury. This provision closely mirrors the protections found under the Hindu Adoptions and Maintenance Act and gives you an alternative or complementary avenue for securing continued maintenance for a dependent child even after they reach eighteen.

If your matrimonial proceedings are being conducted under the Hindu Marriage Act, 1955, Section 26 specifically empowers the court to make interim orders and provisions in the decree regarding maintenance and education of minor children, and while this provision is framed with reference to minor children, courts exercising this power in the course of pending proceedings can and do extend appropriate directions covering continued educational support where the child, though technically no longer a minor by the time the decree is finalised, remains genuinely dependent, particularly where the initial claim was framed and pursued while the child was still legally a minor.

Practically speaking, if your child is approaching eighteen while your case is pending, I strongly advise ensuring that your pleadings and evidence specifically address the child's continuing educational status, financial dependency, and — where applicable — marital status (in the case of a daughter) or any relevant health condition, so that the court has a complete and clear evidentiary basis to continue maintenance beyond the point of technical majority. Waiting until the child actually turns eighteen to raise this issue can create unnecessary procedural friction, so proactively building this into your case from the outset is the more prudent approach.

It's also worth noting what happens if your child later marries (in the case of a daughter) or becomes genuinely self-sufficient through employment — at that point, the paying parent can apply to have the maintenance obligation for that child reduced or terminated, since the underlying statutory basis for continued support after majority is specifically tied to continued dependency, unmarried status, or disability, and once these conditions cease to be satisfied, the obligation correspondingly comes to an end. This works both ways, and it's important for both the paying and receiving parent to understand that continued post-majority maintenance is conditional, not indefinite or automatic regardless of changed circumstances.

Given how fact-specific these continuing maintenance determinations can be — depending heavily on your child's educational trajectory, marital status, and any relevant health considerations — it is worth having your specific situation reviewed by experienced counsel to ensure your pleadings properly capture and preserve your child's continuing right to support. Consulting our legal experts at Aapka Legal Advice can help you structure your maintenance application or ongoing case strategy to withstand any argument that the claim automatically lapsed upon your child reaching eighteen.

For particularly complex situations, such as disputes over a child's genuine educational status or contested claims regarding a child's capacity for self-sufficiency, our panel of retired judges can offer valuable guidance on how Family Courts typically assess these continuing dependency questions based on real-world evidentiary standards. When you're ready to pursue or defend a maintenance claim involving a child who has recently turned eighteen, the Top Divorce Lawyers in Mumbai | Aapka Legal Advice directory connects you with advocates experienced in precisely this nuanced area of family maintenance law.

To bring this together: yes, maintenance in Mumbai can absolutely continue to be claimed for a child who has turned eighteen during pending proceedings, particularly for an unmarried daughter unable to support herself under Section 20(3) of the Hindu Adoptions and Maintenance Act, 1956, for a son still genuinely dependent through ongoing education, and without any age limitation whatsoever for a child suffering from a physical or mental condition preventing self-sufficiency — the key to securing this continued support lies in properly pleading and evidencing the child's continuing dependency rather than assuming the claim automatically ends the moment the child's eighteenth birthday arrives.
