Where a child has special or additional needs, the major decisions about their education generally require both parents’ agreement under joint custody, whatever the day-to-day living arrangement. That makes cooperation both more important and, often, harder. This guide covers who decides, the choices that come up (mainstream or special education, therapy and intervention), how the extra cost features in maintenance, and what to do when parents cannot agree.

The through-line is that these are decisions about the child, not bargaining chips in the divorce, and both the law and the court treat them that way.

Major education decisions usually need both parents

Under joint custody, the significant decisions in a child’s life are made together, and education is squarely one of them. The parent with care and control handles the daily business of school (the uniform, the pick-up, the homework), but the big choices are shared. That includes the decisions that matter most for a child with additional needs.

This holds even where the child lives mainly with one parent. Care and control settles who the child lives with; it does not hand that parent the major decisions. The distinction is explained in our guide to custody versus care and control, and the specific rule for schooling and health is set out in our note on school and medical decisions under joint custody. For a child with special needs, the practical effect is that neither parent can unilaterally move the child to a different school or a different type of provision.

Mainstream or special education

One of the weightiest decisions is whether a child attends a mainstream school, with or without support, or a special education setting geared to their needs. There is no single right answer; it turns on the individual child: the nature and degree of their needs, how they cope, and what each option would actually offer them.

Because it is a major educational decision, it is one both parents are generally expected to make together. Where they share the same read of the child, that is straightforward. Where they do not, one parent set on mainstream inclusion, the other on specialist support, it becomes one of the harder things to resolve, and the sections below on deadlock apply directly.

It also helps to remember that this is rarely a once-and-for-all choice. A child’s needs change as they grow, and a placement that fits at one stage may need revisiting at another. Parents who can keep talking as the picture develops, and who treat professional assessments as shared information rather than ammunition, tend to make these transitions far less painful for the child than parents locked into fixed positions from the start.

Therapy and intervention decisions

Beyond the choice of school, children with additional needs often have a programme of therapies and interventions: speech, occupational, behavioural, and others. Significant, ongoing decisions of this kind tend to engage joint custody in the same way major medical and educational choices do, so they are generally made jointly rather than by one parent alone.

Routine, day-to-day matters usually sit with the parent who has care and control, and it would be unworkable to require agreement on every small thing. The line falls around significance: a major or long-running intervention is a shared decision; the ordinary running of an agreed plan is not. Where parents are broadly aligned, keeping each other informed and consulting on the substantial choices is both good practice and, for major decisions, what joint custody requires.

Cost, and how it features in maintenance

Supporting a child with special or additional needs frequently costs more: specialist schooling, therapy, equipment, and sometimes care. Those additional costs are part of the child’s reasonable expenses, which the court takes into account when assessing maintenance, alongside the ordinary costs of raising a child. How maintenance is worked out in general is set out in our guide to child maintenance in Singapore.

There is a further point that matters for some families. Child maintenance ordinarily runs to a set age, but where a child is unable to support themselves because of a disability, it can continue beyond that. The particular considerations for a child with a disability, including this extended support, are covered in our guide to divorce where you have a child with special needs.

Because these costs can be significant and, in some cases, long-running, it is worth documenting them properly rather than estimating loosely. Fees, therapy costs, equipment and any specialist provision are the kind of expenses the court will want to see set out clearly, so that maintenance reflects the real cost of meeting the child’s needs rather than a rough guess. Keeping records of what the child’s care actually requires helps both parents and the court reach a figure that holds up over time.

When parents cannot agree

Deadlock over a major decision is not unusual, and there is a settled path through it. Start with mediation. A neutral mediator can help two parents work through a decision that is genuinely about the child, separating it from the wider grievances of the divorce, and it resolves many disputes without a hearing.

Mediation is especially suited to these disputes because the underlying question is a genuine one about the child’s future, on which reasonable parents can differ, rather than a straightforward matter of who is right. A mediator can bring the two views into the same room, draw on professional input where it helps, and often find a path that neither parent had seen on their own, all without the cost and strain of a contested hearing.

If mediation does not produce agreement, either parent can bring a specific issue application, asking the court to decide the one question in dispute, such as which school the child should attend, without reopening the whole custody arrangement. The court decides on the basis of the child’s welfare. Because such a decision may sit within, or lead to a change in, the existing orders, it is worth understanding how orders are varied, which we cover in our guide to changing a child custody order.

Keeping the child at the centre

For a child with additional needs, stability and a coherent plan across both homes matter enormously, and disputes between parents cost the child more here than in most situations. The most useful thing separated parents can do is treat education and therapy decisions as shared problems to solve rather than positions to win.
