As summer approaches, many families look forward to travel, long weekends, beach houses, and time away from the usual routine. For separated or divorced parents, however, this time of year often brings a different kind of stress.

Most custody agreements do explicitly address travel. They allocate vacation time, set deadlines for selecting those weeks, and require advance notice and itineraries. Some go further, outlining how disputes are resolved if parents cannot agree, or addressing international travel and related safeguards.

The issue is rarely the absence of rules. It is how those rules are interpreted in practice.

A provision requiring advance notice may be treated by one parent as a firm deadline and by the other as a general guideline. Language requiring notice “as soon as practicable,” or “not less than” a certain number of days, can create different expectations depending on the circumstances. In many cases, parties give the minimum notice required and assume that is sufficient.

Similarly, agreements often include provisions requiring cooperation or stating that consent shall not be unreasonably withheld. While well-intentioned, those terms can lead to disagreement when each parent believes their position is the reasonable one. Even where agreements are highly structured, setting firm deadlines for selecting vacation weeks or establishing alternating priority from year to year, those provisions depend on both parties treating them as meaningful.

In practice, conflict often arises not from the agreement itself, but from the assumptions made around it.

Travel plans may be discussed casually rather than confirmed. An itinerary may be incomplete or provided after arrangements have already been made. One parent may assume flexibility based on past behavior, while the other expects strict compliance with the written terms. By the time there is a disagreement, plans are often in place, expenses have been incurred, and expectations, particularly those of the children, have already been set.

In some cases, these disputes cannot be resolved informally and require court intervention on an expedited basis, particularly where travel is imminent and the parties are unable to agree.

Summer planning is also not limited to travel. Camp schedules, which are often arranged months in advance and involve significant expense, can raise similar issues.

Many agreements attempt to address camp in detail, defining what costs are included, how those costs are shared, and how reimbursement is to be made. Some place limits on expenses or tie them to a particular type of program. Even so, disputes are not uncommon. One parent may enroll a child in a program believing it falls within the agreed framework, while the other questions whether the cost, location, or duration is consistent with what was intended. In other cases, disagreement arises not from the decision itself, but from the timing, whether the expense was discussed in advance or presented after the fact.

Payment structure can create additional friction. Agreements often require one parent to advance payment and seek reimbursement, which in practice depends on timely communication and follow-through by both parties. Delays, partial payments, or differing interpretations of what constitutes a camp expense can quickly turn what appears to be a straightforward provision into a point of contention.

Layered onto all of this is the reality that summer schedules are less structured. Parents may adjust parenting time informally, extending weekends, trading days, or accommodating activities, without clearly confirming expectations. While flexibility can be beneficial, it can also create confusion if it is not communicated in advance.

Information is not always shared directly. It is not uncommon for one parent to learn more about a trip or activity from a social media post than from a conversation. That dynamic tends to escalate situations that might otherwise have been resolved.

From a legal perspective, compliance is measured by whether the terms of an agreement have been followed. From a practical perspective, the situations that lead to conflict are often less clear. Agreements can account for scheduling deadlines, travel requirements, and financial obligations, yet still depend on day-to-day judgment.

The families who navigate summer most smoothly are not necessarily those with the most detailed agreements, but those who approach them with clarity, consistency, and communication.
