When Does Massachusetts Have Jurisdiction Over a Guardianship? Lessons from Guardianship of Finley (2026)

by | Jul 3, 2026 | Guardianship

Key Takeaways

  • A child’s physical presence in Massachusetts does not automatically give a Massachusetts court jurisdiction over a guardianship case. In most interstate disputes, the court must first determine whether Massachusetts has authority to hear the case under the Massachusetts Child Custody Jurisdiction Act, G.L. c. 209B.
  • The child’s “home state” is usually the starting point. Massachusetts law generally gives priority to the state where the child has been living. This applies rather than simply where the child happens to be located when a petition is filed.
  • Subject matter jurisdiction cannot be created by agreement or convenience. Even if every party believes Massachusetts would be the better forum, the Probate and Family Court cannot proceed. This is true unless the jurisdictional requirements established by law have been satisfied.
  • Emergency jurisdiction exists, but it is narrow. Massachusetts courts may exercise temporary emergency jurisdiction in limited circumstances to protect a child. This applies when a child faces abandonment or immediate mistreatment. However, emergency jurisdiction does not automatically allow Massachusetts to permanently decide custody or guardianship issues.
  • The Massachusetts Appeals Court’s decision in Guardianship of Finley reinforces that jurisdiction must be resolved before the court reaches the merits of a guardianship petition. If the court lacks jurisdiction, every order it enters may ultimately become void.

Introduction

When a child suddenly needs a guardian, families must make difficult decisions under extraordinarily stressful circumstances. A parent may be struggling with substance abuse, mental illness, incarceration, housing instability, or a serious medical condition. Grandparents, aunts, uncles, adult siblings, and close family friends frequently step forward to protect the child. They often do this before they fully understand the legal process that lies ahead.

Those situations get even more complex when more than one state is involved. A child may be staying temporarily with relatives in Massachusetts while the parents live elsewhere. Or the family may have recently relocated across state lines. Many people naturally assume that a child’s physical presence in Massachusetts is enough. They believe the Probate and Family Court can simply appoint a guardian.

In many cases, that assumption is wrong.

Like every state, Massachusetts has adopted laws designed to prevent competing custody and guardianship orders involving the same child. Massachusetts law does not allow families to file wherever they believe the outcome may be most favorable. Instead, the court must first determine whether it has jurisdiction to hear the case. Before deciding whether a guardianship is appropriate, the court must determine whether it has the legal authority to act.

The Massachusetts Appeals Court recently addressed these issues in Guardianship of Finley, 25-P-909 (Mass. App. Ct. June 29, 2026). Although the case involved a temporary guardianship of an infant with ties to both Massachusetts and New Hampshire. Its lessons extend to virtually any interstate guardianship dispute. The decision reinforces a fundamental principle of Massachusetts family law. Even the strongest guardianship petition cannot succeed unless the court first has subject matter jurisdiction.

That may sound like a procedural technicality, but it is anything but. Jurisdiction is the legal foundation upon which every guardianship order rests. Before a judge can evaluate a parent’s fitness, determine whether a guardianship is necessary, or decide what arrangement serves the child’s best interests, the court must first answer a more fundamental question: Does Massachusetts have the authority to decide this case? As Guardianship of Finley illustrates, failing to answer that question at the outset can result in months of litigation being undone because the wrong court heard the case.

Why This Decision Matters

Every year, the Massachusetts Appeals Court issues decisions that quietly shape family law cases. These rulings influence how Probate and Family Court judges decide such matters. Most never receive significant public attention, yet they often answer questions that lawyers and families encounter every day. Guardianship of Finley is one of those decisions. It clarifies how Massachusetts courts should analyze interstate guardianship cases. It also reinforces longstanding principles governing subject matter jurisdiction. These principles apply across a wide range of custody and family law disputes.

In this article, we’ll discuss the Massachusetts statutes governing interstate guardianship jurisdiction. We’ll examine the Appeals Court’s decision in Guardianship of Finley. We’ll also review the earlier appellate decisions upon which the court relied. Finally, we’ll explain what this case means for families, guardians, and practitioners handling multi-state custody and guardianship matters. Along the way, we’ll offer practical litigation insights and examples. These illustrate how jurisdictional principles frequently arise in real Probate and Family Court cases.

The Massachusetts Law Governing Interstate Guardianship Cases

Before a Massachusetts Probate and Family Court can decide whether a guardianship is appropriate, it must first answer a threshold legal question: Does the court have jurisdiction to hear the case?That issue comes before every other consideration. A judge cannot decide whether a parent is fit, whether a child would be better off living with a grandparent, or whether a guardianship is in the child’s best interests until the court first determines that Massachusetts has the legal authority to make those decisions. As Guardianship of Finley demonstrates, jurisdiction is not a procedural technicality. It is the legal foundation upon which every custody and guardianship order rests.

Massachusetts addresses interstate custody and guardianship disputes through the Massachusetts Child Custody Jurisdiction Act (MCCJA), G.L. c. 209B. Although guardianship proceedings are governed procedurally by the Massachusetts Uniform Probate Code, G.L. c. 190B, guardianship cases involving minor children are also considered “custody proceedings” for purposes of the MCCJA because they determine who has legal responsibility for the child’s care and decision-making. Accordingly, before appointing a guardian for a minor child with connections to multiple states, the Probate and Family Court must determine whether jurisdiction exists under G.L. c. 209B.

The Legislature adopted the MCCJA to solve a very practical problem. Before states adopted uniform jurisdictional rules, competing custody orders were common. Multiple courts in different states would issue orders involving the same child. Parents or relatives sometimes attempted to gain a tactical advantage by moving a child across state lines. They would then file a new custody action in what they believed would be a more favorable forum. The result was confusion, inconsistent court orders, and prolonged litigation that often placed children in the middle of interstate legal disputes. The MCCJA seeks to prevent those outcomes by establishing clear rules. These rules determine which state has primary authority to decide custody-related matters.

The Supreme Judicial Court has repeatedly recognized these purposes. In Custody of Victoria, 473 Mass. 64 (2015), the Court explained that the jurisdictional statutes are intended to avoid conflicting custody determinations, discourage forum shopping, and promote cooperation between states so that custody disputes are ordinarily resolved in the forum with the closest connection to the child. Those principles did not originate with Victoria. They trace back decades and continue to guide Massachusetts courts whenever interstate custody or guardianship issues arise.

In most cases, the analysis begins with what lawyers commonly refer to as the child’s home state. Under G.L. c. 209B, the home state is generally the state where the child has lived with a parent or person acting as a parent for the six months immediately preceding the commencement of the proceeding, or, in the case of an infant less than six months old, the state where the child has lived from birth. While exceptions exist, the home state ordinarily has the first opportunity to decide custody and guardianship matters. Courts presume the home state to be where the greatest access to evidence exists concerning the child. This evidence includes the child’s care, education, family relationships, and overall well-being.

That principle proved decisive in Guardianship of Finley. Although the child was born in Massachusetts, the Appeals Court concluded that New Hampshire—not Massachusetts—qualified as the child’s home state because the child had lived there from birth with his parents. The fact that the child was physically present in Massachusetts when the guardianship petition was filed did not change that analysis. The court looked beyond geography on the day of filing and instead focused on the jurisdictional framework established by G.L. c. 209B. Because New Hampshire satisfied the statutory definition of the child’s home state and had already exercised jurisdiction, Massachusetts lacked authority to proceed. Guardianship of Finley, 25-P-909 (Mass. App. Ct. June 29, 2026).

One of the most common mistakes in interstate guardianship cases is assuming that a child’s physical presence in Massachusetts automatically creates jurisdiction. It generally does not. Before filing a guardianship petition involving another state, determine where the child has actually been living, whether another custody or guardianship proceeding is pending, and whether another state qualifies as the child’s home state under G.L. c. 209B.

Not every case, however, fits neatly within the home-state rule. Recognizing that children sometimes require immediate protection, G.L. c. 209B permits Massachusetts courts to exercise temporary emergency jurisdiction in limited circumstances, such as when a child has been abandoned or faces mistreatment or abuse. That authority is intentionally narrow. It allows the court to protect the child until the state with primary jurisdiction can act, but it does not ordinarily permit Massachusetts to assume permanent jurisdiction simply because the child is temporarily present here.

The Supreme Judicial Court reinforced that principle in Care & Protection of Faraj, 496 Mass. 426 (2025), emphasizing that protecting children and respecting interstate jurisdiction are complementary goals. The statutory framework allows Massachusetts to respond to emergencies while avoiding conflicting long-term custody and guardianship orders.

Likewise, Custody of Brandon, 407 Mass. 1 (1990), Adoption of Anisha, 89 Mass. App. Ct. 822 (2016), and Custody of Vale, 106 Mass. App. Ct. 381 (2025) all recognize that jurisdiction under the MCCJA is statutory and cannot be created by agreement, waiver, or convenience. Guardianship of Finley builds on those decisions by reaffirming that subject matter jurisdiction is a prerequisite to every guardianship case. Because the Probate and Family Court lacked jurisdiction from the outset, the Appeals Court vacated every guardianship order without ever reaching the merits of the petition.

Litigation Insight

Experienced family law practitioners often analyze jurisdiction before they analyze the merits of a case. That may seem counterintuitive to clients, who understandably want to discuss the child’s safety or the parent’s conduct first. However, if the wrong court hears the case, months of litigation may ultimately prove meaningless. As Guardianship of Finley demonstrates, establishing jurisdiction is not simply the first procedural hurdle—it is the prerequisite to every substantive decision the court will later make.

How These Jurisdictional Rules Apply in the Real World

The jurisdictional principles discussed above may seem technical, but they frequently arise in situations families never expect. One of the most important lessons from Guardianship of Finley is that before a Probate and Family Court judge can determine whether a guardianship is appropriate, the court must first determine whether Massachusetts has jurisdiction to hear the case. The following examples illustrate how these issues commonly arise under G.L. c. 209B.

A Grandparent Brings the Child to Massachusetts

Imagine that a child’s parents live in Vermont but are struggling with substance abuse. Concerned for the child’s safety, the maternal grandmother brings the child to Worcester with the parents’ consent. A few weeks later, she files a guardianship petition so she can enroll the child in school and authorize medical treatment.

Although many people would assume Massachusetts can simply appoint the grandmother as guardian, the court’s first question is likely to be whether Vermont remains the child’s home state under G.L. c. 209B. If it does, Massachusetts may lack jurisdiction even if everyone agrees the grandmother should serve as guardian.

Guardianship Practice Tip

When a child comes to Massachusetts temporarily, do not assume that time alone creates jurisdiction. Before filing, determine whether another state retains home-state jurisdiction or whether you should instead initiate proceedings there.

A Child Arrives During an Emergency

Now imagine someone brings a child to Massachusetts after allegations of serious abuse in another state. The child is safe with relatives, but there are legitimate concerns that returning the child immediately would place the child at risk.

In that situation, Massachusetts may exercise temporary emergency jurisdiction under G.L. c. 209B to protect the child while the jurisdictional issues are resolved. As Care & Protection of Faraj and Guardianship of Finley illustrate, emergency jurisdiction exists to address immediate safety concerns, not to permanently transfer jurisdiction away from the child’s home state.

The Family Permanently Relocates

Suppose a family permanently moves from Connecticut to Massachusetts, enrolls the children in school, establishes medical care, and builds their lives here before a guardianship issue arises.

Unlike the earlier examples, Massachusetts may now qualify as the child’s home state under G.L. c. 209B, giving the Probate and Family Court primary jurisdiction over the guardianship. The analysis focuses on where the child has actually been living during the statutory period, not where the child was born or where extended family members reside.

Competing Proceedings in Two States

Filing proceedings in multiple states complicates interstate disputes. Imagine that an aunt files a guardianship petition in Massachusetts while the child’s father files a custody action in New Hampshire involving the same child.

To avoid conflicting orders, G.L. c. 209B, § 2(d) generally prohibits Massachusetts from exercising jurisdiction if another state’s custody proceeding was commenced first and that court is properly exercising jurisdiction. That principle was central to the Appeals Court’s decision in Guardianship of Finley, where the pending New Hampshire proceeding further supported the conclusion that Massachusetts lacked jurisdiction.

Litigation Insight

Experienced guardianship attorneys typically analyze jurisdiction before addressing the merits of the case. Identifying the child’s home state, determining whether another proceeding is already pending, and evaluating whether emergency jurisdiction exists can prevent months of unnecessary litigation. As Guardianship of Finley reminds us, the strongest evidence in support of a guardianship cannot overcome a lack of subject matter jurisdiction.

A Fictional Example: How Guardianship of Finley Might Apply in Practice

The following fictional example illustrates how these jurisdictional principles may arise in a real guardianship case involving more than one state.

Michael and Jennifer lived in Nashua, New Hampshire, with their four-year-old son, Ethan, who had lived there since birth. He attended preschool in New Hampshire, received medical care there, and had virtually all of his family, school, and medical connections in the state. Jennifer’s sister, Lisa, however, lived just across the border in Lowell, Massachusetts.

As Michael and Jennifer’s opioid addiction worsened, they asked Lisa to care for Ethan temporarily while they sought treatment. Lisa agreed, believing the arrangement would last only a few weeks. When it became clear the parents were not improving, she decided she needed legal authority to enroll Ethan in preschool, consent to medical care, and make other important decisions. She filed a guardianship petition in the Middlesex Probate and Family Court.

From Lisa’s perspective, the case appeared straightforward. Ethan was living safely in Massachusetts, his parents supported the arrangement, and appointing Lisa as guardian seemed to be in everyone’s best interests. Under Guardianship of Finley, however, those facts would not answer the court’s first question. Before considering whether Lisa was an appropriate guardian, the court would first determine whether Massachusetts had jurisdiction under G.L. c. 209B.

Suppose, however, that Ethan arrived in Massachusetts after both parents were found unconscious from an overdose and immediate intervention was necessary to protect him. In that circumstance, Massachusetts could exercise temporary emergency jurisdiction under G.L. c. 209B while New Hampshire addressed the longer-term custody issues. Temporary emergency jurisdiction, however, would not automatically give Massachusetts authority to decide the guardianship permanently.

Now assume Lisa continues litigating the Massachusetts case, unaware that Ethan’s paternal grandparents had already filed a guardianship petition in New Hampshire. After months of hearings, the Probate and Family Court appoints Lisa as Ethan’s permanent guardian. Only later does everyone discover the pending New Hampshire proceeding.

At that point, the Massachusetts orders could face the same fate as those in Guardianship of Finley. If New Hampshire was Ethan’s home state and was properly exercising jurisdiction, the Massachusetts guardianship orders could be void. The issue would not be whether Lisa was an excellent guardian or whether Ethan was thriving in her care. The dispositive question would be whether the Massachusetts court ever had the legal authority to decide the case.

Guardianship Practice Tip

When an interstate guardianship becomes necessary, protecting the child should always be the immediate priority. At the same time, families should determine where the child has been living, whether another state has already become involved, and whether Massachusetts is exercising temporary emergency jurisdiction or permanent jurisdiction. Addressing those issues early can prevent months of litigation from unraveling when someone files the case in the wrong forum.

Why Guardianship of Finley Matters

At first glance, Guardianship of Finley may appear to be a narrow procedural decision involving an unusual set of facts. In reality, it reinforces one of the most fundamental principles governing interstate family law litigation: a court cannot decide the merits of a guardianship case until it first determines that it has jurisdiction to do so.

The Appeals Court did not announce a new rule of law. Rather, it applied longstanding principles reflected in G.L. c. 209B and earlier decisions such as Custody of Brandon, Custody of Victoria, Adoption of Anisha, Care & Protection of Faraj, and Custody of Vale. Taken together, these cases consistently emphasize that jurisdiction exists to protect children from conflicting court orders, discourage forum shopping, and ensure that one court—not several—has primary responsibility for deciding issues affecting a child’s welfare.

The decision should also serve as a reminder to practitioners. It is easy to become focused on proving that a guardianship is necessary or that a proposed guardian is well-qualified to care for the child. Those issues are critically important, but they come second. The first responsibility in any interstate guardianship case is determining whether the Probate and Family Court has subject matter jurisdiction. As Guardianship of Finley demonstrates, even a well-intentioned guardianship supported by compelling evidence cannot stand if it was entered by a court that lacked the authority to hear the case.

Litigation Insight

Guardianship of Finley teaches one of the most valuable lessons: never treat jurisdiction as an afterthought. Experienced guardianship attorneys often begin by creating a jurisdictional timeline that identifies where the child lives, when the child moves, whether another proceeding exists, and which state’s law governs. That analysis frequently shapes every strategic decision that follows and can prevent months of unnecessary litigation before the parties ever reach the merits of the guardianship itself.

Frequently Asked Questions About Interstate Guardianships in Massachusetts

1. If a child is physically present in Massachusetts, can a Massachusetts court automatically appoint a guardian?

No. A child’s physical presence in Massachusetts, standing alone, does not automatically give the Probate and Family Court jurisdiction to appoint a guardian. Before the court may reach the merits of the petition, it must determine whether jurisdiction exists under the Massachusetts Child Custody Jurisdiction Act, G.L. c. 209B. As Guardianship of Finley demonstrates, a court that lacks subject matter jurisdiction cannot issue a valid guardianship order, regardless of the child’s best interests.

2. What is a child’s “home state” under Massachusetts law?

Generally speaking, the home state is the state where the child has lived with a parent or person acting as a parent during the six months immediately preceding the filing of the action. For children younger than six months old, it is ordinarily the state where the child has lived from birth. Determining the child’s home state is often the starting point in any interstate custody or guardianship dispute because that state will usually have primary jurisdiction under G.L. c. 209B.

3. Can parents simply agree that Massachusetts should decide the guardianship?

No. An agreement, waiver, or consent cannot create subject matter jurisdiction. Even if every party involved would prefer to litigate in Massachusetts, the Probate and Family Court must independently determine whether it has jurisdiction under the governing statute. If it does not, any orders entered by the court may ultimately be declared void.

4. What happens if guardianship cases are filed in two different states?

Massachusetts law specifically aims to avoid competing custody and guardianship orders. Under G.L. c. 209B, § 2(d), Massachusetts will generally decline jurisdiction if another state has already commenced a custody proceeding and is exercising jurisdiction consistently with the statute. Courts should respect one another’s jurisdiction and, when appropriate, communicate with one another to avoid conflicting decisions affecting the same child.

5. Can Massachusetts exercise emergency jurisdiction?

Yes, but only in limited circumstances. G.L. c. 209B permits Massachusetts courts to exercise temporary emergency jurisdiction when a child has been abandoned or needs immediate protection because of mistreatment or abuse. Emergency jurisdiction protects the child until the state with primary jurisdiction acts; it is not ordinarily a mechanism for permanently transferring a custody or guardianship dispute to Massachusetts.

6. Does Guardianship of Finley change Massachusetts law?

Not in the sense of creating a new legal rule. Rather, the Appeals Court reaffirmed longstanding jurisdictional principles that have existed under the MCCJA for decades. The decision is significant because it applies those principles in the guardianship context and reinforces that the Probate and Family Court must always resolve jurisdiction before it reaches the merits of a petition.

7. Why is subject matter jurisdiction treated so differently from other legal issues?

Subject matter jurisdiction concerns the court’s legal authority to hear a particular type of case. Unlike many procedural rights, neither the parties nor the court can waive or overlook it. If jurisdiction is lacking, every order entered by the court is void, even if the proceedings were otherwise fair and the result appeared to serve the child’s best interests.

8. What should relatives do before filing an interstate guardianship petition?

One of the first steps should be determining where the child has actually been living and whether another state may qualify as the child’s home state. It is equally important to check whether anyone is already pursuing another custody or guardianship proceeding. Addressing those questions before filing often avoids significant jurisdictional disputes later in the case.

Final Thoughts

When families seek a guardianship, they are focused on one question: What is best for the child? Massachusetts law requires courts to answer another question first: Does the court have the legal authority to decide the case? As Guardianship of Finley reminds us, jurisdiction is not a procedural technicality. It is the legal foundation upon which every guardianship order rests.

The decision also highlights the importance of addressing jurisdiction at the very beginning of an interstate guardianship case. Determining the child’s home state, whether another court is already exercising jurisdiction, and whether emergency jurisdiction exists can prevent months of unnecessary litigation and conflicting court orders.

At Turco Legal, we’ve found that resolving these jurisdictional issues early often allows families to focus on what truly matters: protecting the child and creating a stable path forward. Guardianship of Finley is a valuable reminder that before a court can determine a child’s best interests, it must first determine that it has the authority to do so.
