In most of the country, child support ends when a child turns 18 or finishes high school. What happens to college is between the parents — the court is out of it. Massachusetts is one of a small group of states, along with New Jersey and New York, where that isn't true. Here, a judge can order a divorced parent to help pay for college, years after the divorce is final and the child is legally an adult.
For divorcing parents of younger kids, this is easy to miss. It doesn't feel urgent when your child is four or eleven. But the decisions made in a divorce agreement now, often before anyone has thought seriously about tuition, can shape what a judge is willing to order later.
Under Massachusetts General Laws Chapter 208, Section 28, a court may order a parent to contribute to a child's undergraduate education past age 18. Specifically:
• From 18 to 21, a court can order support for a child who is "domiciled in the home of a parent" and "principally dependent upon said parent for maintenance" — language the courts have interpreted to include a child who's away at school for the academic year but still considers a parent's home their base.
• From 21 to 23, the same standard applies, but only if the child is enrolled in an educational program. Graduate school isn't covered.
None of this is automatic. A judge decides whether to order it, weighing each parent's finances, the cost of the school relative to what's reasonable, the child's aptitude and commitment, available financial aid, and what the parents expected or promised before the divorce.
There's also a built-in ceiling: under the state's child support guidelines, no parent can be ordered to pay more than 50% of the in-state cost of attending UMass Amherst — tuition, fees, room and board — unless the court specifically finds that parent can afford more. A child heading to an expensive private school doesn't automatically translate into a bigger court-ordered bill.
First: college contribution and child support are treated as separate obligations in Massachusetts. Ordering one doesn't automatically reduce or replace the other. A parent can end up paying standard child support and a share of college costs at the same time, even after the child has effectively moved out for the school year. A court can adjust the child support order once a child is away at school, but only if someone asks — it doesn't happen on its own.
Second: Massachusetts courts are notably reluctant to order college contribution after the fact, especially when the paying parent had no say in where the child applied or enrolled. Judges have consistently declined to hand a parent a bill for a decision they weren't part of. That means the real leverage point isn't when the tuition bill arrives — it's years earlier, in the divorce agreement.
If there's a 529 plan or other college fund from the marriage, it doesn't disappear from the conversation just because it has a child's name attached. Existing college savings are typically treated as a resource the court can weigh when deciding how much each parent should contribute, not as a substitute for addressing the issue in the agreement. Parents who assume "we already have a 529, so we don't need to spell this out" are often the ones back in court later, arguing over who controls the account and how it gets spent.
These are the items worth addressing in the agreement:
• Whether college costs will be split by percentage, capped at a dollar amount, or tied to a benchmark like UMass in-state cost
• Whether both parents need to agree on which schools count as reasonable choices
• How an existing 529 or savings account factors into each parent's contribution
• How college contribution interacts with an ongoing child support order
None of this requires predicting where your child will apply in a decade. It means treating college as a cost the divorce agreement should anticipate, not a surprise to be litigated when the acceptance letter arrives.
Massachusetts is genuinely unusual in giving courts this authority, and unusual in how it's structured — the age 23 cutoff, the UMass-based cap, and the fact that college support and child support run on separate tracks. Whether you're negotiating a divorce agreement or already have one that is silent on college expenses, addressing the issue early with a family law attorney can help avoid uncertainty and disagreement later.
