Sabbaticals and Research Leave in a Parenting Plan

California has no special "sabbatical custody" law. A sabbatical matters to a parenting plan in two ways. It may change the parenting schedule while one parent is away. It may also change where the child lives, which can bring in the notice rule of Family Code section 3024 and the relocation rule of Family Code section 7501.

Most people facing this question are in the middle of something concrete. A UC San Diego faculty member has an approved leave to work abroad for a year. Or a co-parent has just announced a research appointment in another state and wants to bring the children. Either way, a custody order already exists, the academic calendar is moving, and the parent is trying to work out whether the plan they signed even covers this, and what the other parent can do about it.

This page walks through the law that actually applies. It covers what a UC sabbatical looks like on a calendar, when notice is owed, when a leave turns into a relocation, and how a La Jolla custody case is handled at the San Diego Superior Court when parents do not agree.

What a Sabbatical Means Under California Family Law

"Sabbatical custody" is not a term the California Family Code uses. The legal questions are narrower and more practical. First, does the leave change the child's residence, or does only the parent travel? Second, does the existing parenting plan already say what happens when one parent is away for an extended period?

Those two questions sort sabbaticals into very different situations. A parent who spends a quarter at a lab in another country while the children stay in their La Jolla home creates a scheduling problem. The children's school, home and daily routine stay the same; only the parenting time shifts. A parent who wants the children to come along for a year in another city, state or country raises a residence question, and that brings in two specific statutes.

The first is Family Code section 7501, which gives a parent entitled to custody a right to change the child's residence, "subject to the power of the court to restrain a removal that would prejudice the rights or welfare of the child." The second is Family Code section 3024, which lets the court include a notice requirement in a custody order. Both are covered in their own sections below.

For La Jolla families tied to UC San Diego or one of the area's research institutions, these questions come up more often than in many places. Academic careers run on leave cycles, visiting appointments and fixed quarters, and a parenting plan written around a regular school year can stop fitting once a leave is approved. The broader framework for these families is covered in custody for academic and clinical careers.

UC Sabbatical Policy and What It Means for Parenting Schedules

The University of California's Academic Personnel Manual, section APM 740 (Rev. 10/28/2025), sets the rules for sabbatical leave across the UC system. Several of its terms matter directly to anyone trying to fit a leave into a custody schedule.

APM 740 states that "Sabbatical leaves are not granted as a matter of individual right." An application goes through appropriate channels to the Chancellor. A faculty member may plan a sabbatical for years, but until it is approved, the leave and its dates are not settled.

APM 740 also sets a defined return. Immediately after the leave, "the recipient will return to active University service for a period at least equal to the period of the leave." The policy allows some limited variations with the Chancellor's approval, such as delaying the return during unpaid leave, or interrupting the sabbatical. Still, the basic structure is a leave with an end date and a required period back on campus.

On pay, APM 740 says only that "Regular sabbatical leave provides salary at varying percentages of regular salary." How that pay is treated for support purposes is a separate question, covered in nine-month salaries and sabbatical pay.

The ordinary academic calendar also matters. Under APM 740, an academic-year appointee "works two (2) semesters or three (3) quarters." UC San Diego Academic Personnel Services states that academic appointees with academic-year appointments are expected to be in residence from the first day of the fall quarter through the last day of the spring quarter, except during official University holidays. The same Academic Personnel Services page also states plainly: "Appointees who leave the campus prior to obtaining a formal approval are in violation of UC and UC San Diego policy." It adds that for research-related leaves or leaves that can be anticipated and planned in advance, best practices would be to ensure department chairs or academic divisions receive between one quarter and one academic year's advance consultation.

Put together, this is why a sabbatical is not a vacation. It is a structured academic leave with an approval step, set dates and a return obligation. For a parenting plan, the useful point is that the approved leave dates give a firm date range to work from. An expected or informal start date gives much less to rely on.

The 45-Day Notice Rule Under Family Code Section 3024

Section 3024 is often described as a flat "45-day rule." The text is more specific than that. It reads in part:

"In making an order for custody, if the court does not consider it inappropriate, the court may specify that a parent shall notify the other parent if the parent plans to change the residence of the child for more than 30 days, unless there is prior written agreement to the removal. The notice shall be given before the contemplated move, by mail, return receipt requested, postage prepaid, to the last known address of the parent to be notified. A copy of the notice shall also be sent to that parent's counsel of record. To the extent feasible, the notice shall be provided within a minimum of 45 days before the proposed change of residence so as to allow time for mediation of a new agreement concerning custody."

A few points follow from that language. The notice duty comes from the custody order itself: the court may include it, and many orders do. It concerns a change in the child's residence for more than 30 days, which can describe a year-long sabbatical abroad. It does not apply where there is prior written agreement to the move. And the 45-day period is framed as "to the extent feasible," with a stated purpose: to give time for mediation of a new custody agreement.

A parent's own travel is a different matter. If a parent goes away for a research leave and the child stays in La Jolla, the child's residence has not changed, and section 3024 notice would not seem to be triggered. The question then becomes what the existing parenting plan says about extended absences, and whether its schedule still works.

Notice is also not permission. The statute gives the other parent time to respond, including through mediation; it does not say the move may go forward once the time runs. A parent who learns from a co-parent's letter that the children may spend next year elsewhere is often unsure what the letter means. Legally, it opens a window to talk or to ask the court for help. It does not decide anything.

When a Sabbatical Becomes a Relocation: Family Code Section 7501

When a leave would take the child to live somewhere else, section 7501 becomes the central rule. Subdivision (a) reads in full:

"A parent entitled to the custody of a child has a right to change the residence of the child, subject to the power of the court to restrain a removal that would prejudice the rights or welfare of the child."

The right is real, but it is qualified. The court has power to stop a move that would harm the child's rights or welfare. Subdivision (b) states the Legislature's intent to affirm In re Marriage of Burgess (1996) 13 Cal.4th 25 as the law of the state.

More broadly, custody orders in California turn on the child's best interests. Family Code section 3020 makes the child's health, safety and welfare the court's primary concern. It also states a policy of frequent and continuing contact with both parents after separation, except where that contact would not be in the child's best interests. Family Code section 3011 lists factors the court must consider, including the nature and amount of the child's contact with both parents.

A sabbatical presents a particular set of facts. A temporary move for a defined period, with a return date tied to the UC return-to-service obligation, is different from a permanent move to take a new job. Those facts can weigh in the analysis; the statute does not promise that either kind of move will be allowed or stopped. Permanent moves for a new appointment are covered in moving away for a new position, and moves out of the country in relocating abroad with a child.

The paths here are the same as for most custody changes. Parents who agree on a temporary schedule for the leave can put it in writing as a stipulated order (an agreement the court signs and makes an order). Where they do not agree, either parent may ask the court to modify custody or visitation for the leave period.

Building a Parenting Plan That Accounts for Academic Leave

A parenting plan can address academic leave before it happens. A plan written with an academic household in mind might describe the triggering event (a formally approved leave under APM 740 or a similar policy), how and when notice is given, and a temporary schedule that takes effect for the leave period.

Approved leave dates make a natural anchor. Because UC San Diego treats leaving campus without formal approval as a policy violation, and because APM 740 sets a return-to-service period, the approved start and end dates are reliable reference points. A provision keyed to those dates is clearer than one keyed to "whenever the leave begins."

The variables a plan typically covers include:

• whether the child travels with the departing parent or stays in La Jolla;
• how parenting time shifts to the other parent during the leave, and how it is made up, such as through holiday or summer time;
• how the child and the parent who is not with them stay in contact, including regular calls or video;
• what happens if the leave is extended, cut short or interrupted, which APM 740 allows in limited cases.

Where these plans are filed matters too. Most family law cases from La Jolla ZIP codes are filed in the Central Division of the Superior Court of California, County of San Diego, at the Central Courthouse, 1100 Union Street, San Diego, CA 92101. For parents without a lawyer, the court's Family Self Help Center (Family Law Facilitator) lists child custody and visitation among the help it provides. According to the Family Self Help Center, the Family Law Facilitator's Office provides help at no cost, and its staff includes attorneys, paralegals and clerks who can help prepare court forms and provide general legal information. The Family Self Help Center also offers an online guide to request new or modified custody, visitation or child support orders in existing family law cases. The court describes the facilitator's staff as neutral court employees who are not anyone's lawyer, and notes it does not assist parties who have an attorney of record. Its offices include one at the Central Courthouse.

What Happens When Parents Cannot Agree

Disagreement over a sabbatical usually reaches the court through a request to modify the existing custody or visitation order. Under Family Code section 3170(a), when a petition or other pleading to obtain or modify a custody or visitation order shows those issues are contested, "the court shall set the contested issues for mediation." This step is required, not optional.

In San Diego County, that mediation is child custody recommending counseling with the court's Family Court Services. Under Family Code section 3183(a), the mediator, called a child custody recommending counselor, may, consistent with local court rules, submit a recommendation to the court, if the recommendation is first given in writing to the parties and their attorneys before the hearing. Family Court Services calls this person the Family Court Counselor. According to Family Court Services, if no agreement is reached, the Family Court Counselor makes a recommendation to the court, and the court hearing proceeds. The judge decides.

Section 3170(b) adds that domestic violence cases are handled by Family Court Services under a separate written protocol approved by the Judicial Council.

A leave often starts on a fixed date while a case is still moving, which is one of the most stressful parts of this situation for a parent. Courts can make temporary custody orders to cover a period while a longer-term arrangement is worked out. In deciding, the court looks at the child's best interests under sections 3011 and 3020, including the child's contact with both parents, stability, and here, the defined, temporary nature of the leave. None of this makes any outcome assured.

If You'd Like to Talk Through a Leave and Your Parenting Plan

A sabbatical question turns on specific details: what the current custody order actually says about notice and extended absences, whether the child would move or stay, the approved leave dates and return-to-service period, and how the children's school year lines up with the quarters away. A consultation is the place to go through those facts against sections 3024 and 7501 and see which parts of the law matter most for a particular family. The firm practices California family law only, so questions about the university employment side of a leave belong with the campus's own offices.
