How to modify child custody and parenting time in Maryland
Sources last checked 8 November 2026. Information only, not legal advice. This page rests on two court decisions: the Maryland Supreme Court’s McCready v. McCready, 323 Md. 476, 593 A.2d 1128 (1991), read on CourtListener (the court was then called the Court of Appeals of Maryland), and the Appellate Court’s later Gillespie v. Gillespie, 206 Md. App. 146, 47 A.3d 1018 (2012), read on FindLaw. We did not read any Maryland statute, so treat this as the case-law test rather than the whole of it. Read what we could not confirm below.
The short version
In Maryland the question that decides a custody case is always the child’s best interest. But before a court will re-open an existing custody order, you ordinarily have to show something has changed since the last hearing. The court said “the best interest of the child” is the appropriate standard in a contested custody case, and that “a material change in circumstances which relates to the welfare of the child” is often important. The two work together: the change is usually weighed as part of the best-interest decision, not applied as a separate gate.
How the test works, from McCready
- Why a change is usually required. The court gave two reasons: stability in a child’s life, and finality. It said a disappointed parent must not be allowed to “relitigate questions of custody endlessly” on the same facts, and that “An order determining custody must be afforded some finality”.
- But orders can change. The same sentence says an order may still be modified “when changes so warrant to protect the best interest of the child”. The court quoted an earlier case: “custody decrees are never final in Maryland”.
- Look at what happened since the last hearing. The court said any reconsideration should emphasize changes in circumstances that occurred after the last court hearing. It noted a possible exception for important facts that existed but were unknown and not reasonably discoverable when the first order was made.
- If you offer nothing new, you lose. Where the parent seeking a change is “offering nothing new” and is only trying to relitigate, “the effort will fail on that ground alone”.
- In most cases, the two questions merge. Where there is some evidence of change, the court said deciding whether the changes are enough “necessarily requires a consideration of the best interest of the child”. The court said the question of changed circumstances may “infrequently be a threshold question” and is more often part of the best-interest decision, where stability is “an important factor”.
- Agreed orders count too. The court said it treats custody orders entered by consent as final, “subject to modification upon a sufficient showing of change”. It declined to treat agreement-based orders differently.
- Judges have wide discretion. On appeal, the court will not interfere with a custody decision without “a clear showing that the chancellor abused his discretion”.
A later case that restates the test: Gillespie (2012)
- Burden. Quoting an earlier decision, Gillespie says “The burden is then on the moving party” to show a material change in circumstances since the final custody order and that changing custody is now in the child’s best interest.
- What “material” means. Quoting another case, the court said the term relates to “a change that may affect the welfare of a child”.
- It repeats McCready’s point. The court restated that changed circumstances may only “infrequently be a threshold question” and is more often part of the best-interest decision.
- A worsening can count. In Gillespie the circuit court did not treat a parent’s long-standing mental illness as the change itself. It found a material change in “an extreme deterioration” of her symptoms, and the Appellate Court found enough evidence for that finding. One case, decided on its facts: do not read it as a rule that every worsening qualifies.
What this means for you
- Pro: The test is flexible. If something real has changed for your child since the last order, the court can weigh it against the child’s best interest without a rigid checklist.
- Con: Flexible also means unpredictable. McCready gives no list of what counts as a sufficient change, and the judge has wide discretion.
- Gather evidence of what changed. Dates, schools, schedules, health, a parent’s work or home, and how the current arrangement affects your child. A complaint about the earlier order alone is exactly what McCready says will fail.
What we could not confirm
- Later cases. McCready is from 1991. Beyond Gillespie (2012) we did not read later Maryland decisions, such as McMahon v. Piazze, so we cannot say what changes courts accept today or whether the test has shifted since 2012.
- Statutes. We did not read the Maryland Family Law Article’s custody provisions, the best-interest factors, or its relocation rules.
- Joint custody and shared time. McCready involved a change from shared physical custody to primary custody with the father. We did not read how current Maryland cases treat shared arrangements.
- Forms and filing. We did not confirm a Maryland court form for a request to modify, filing fees, fee waivers, mediation requirements, or which circuit court hears your case.
- An unreported opinion. We looked at an unreported Appellate Court opinion on the same subject, but Maryland rules bar citing unreported opinions in court filings, so we did not rely on it.
