When 18 Is Not the End: Dependent Adult Children in Financial Remedy Proceedings

In divorce proceedings, many people assume that a child turning 18 brings financial responsibility to an end. Legally, 18 marks adulthood. In reality, particularly in financial remedy proceedings, the position is far more nuanced.

Under section 25 of the Matrimonial Causes Act 1973, the court must consider the financial needs, obligations and responsibilities of each party — both now and in the foreseeable future. That includes responsibilities towards children who, although legally adults, remain financially dependent.

This issue frequently arises in two scenarios: university-aged children and adult children with disabilities or long-term conditions.

University and Ongoing Education

Where a child progresses directly from school to university or further education, the court commonly treats them as financially dependent.

In assessing financial remedy, judges will often take into account:

Tuition fees (particularly where privately funded),
Accommodation and living expenses,
Travel and associated educational costs,
The standard of living enjoyed during the marriage,
The parents’ financial resources.

Importantly, this is not a CMS child maintenance exercise. The court does not make an order “for” the adult child. Instead, anticipated education costs are typically reflected through:

Increased capital provision,
Extended or enhanced spousal maintenance,
Or structured lump sums.

The obligation is viewed as a foreseeable financial responsibility flowing from the marriage.

Adult Children With Disabilities or Neurodevelopmental Conditions

The position becomes more significant where an adult child cannot achieve independence due to:

Physical disability or chronic illness,
Mental health conditions,
Autism spectrum disorder (ASD),
ADHD,
Learning disabilities or behavioural conditions.

In such cases, dependency may be long-term or permanent.

The court will examine:

Functional independence (capacity to work or live alone),
Care arrangements (which parent provides primary support),
Housing requirements (including adapted accommodation),
Ongoing financial vulnerability.

Where one parent continues to provide day-to-day care beyond 18, that responsibility directly affects their own financial needs. Housing may need to accommodate lifetime co-residence. Earning capacity may be restricted. In appropriate cases, this can justify enhanced capital provision or longer-term maintenance.

It is crucial to understand that the court is not awarding financial provision to the adult child directly. Rather, it is recognising that a spouse’s needs are shaped by ongoing caregiving obligations.

The Strategic Importance in Financial Remedy

In higher value cases, adult dependent children can materially influence the overall outcome — particularly in relation to housing and maintenance structure.

In more modest asset cases, the balancing exercise can be even more acute, with the court carefully weighing competing adult needs against finite resources.

There is no automatic rule. The court exercises discretion, guided by evidence and proportionality.

Medical reports, educational plans and clear financial forecasting are often critical in establishing the true extent of dependency.

Why Early Legal Advice Matters

These cases are highly fact-specific. The way adult dependency is framed — evidentially and legally — can significantly affect the structure of any settlement or court order.

Obtaining specialist advice at an early stage ensures that:

Future educational costs are properly quantified,
Long-term care needs are appropriately evidenced,
Housing requirements are realistically assessed,
Strategic decisions are made with clarity and foresight.

We regularly advise clients navigating divorce where adult children remain financially dependent due to education or disability. Careful preparation and strategic presentation of these issues can be outcome-determinative.

Turning 18 is a legal milestone. It is not always a financial one.
