How to Modify Child Custody in Massachusetts

Reviewed by DocDraft Legal Team · Massachusetts · Last updated October 7, 2026

Massachusetts is the rare state where a child's own consent, not just a parent's, can decide whether that child may be taken out of state. Modifying child custody here means filing a fresh complaint asking the Probate and Family Court that issued your existing custody or parenting time order to change it, because something significant has changed since the judge signed it. Nothing makes you wait. Thirteen separate waiting period phrasings return zero hits across the custody sections of General Laws chapters 208 and 209C, so no interval sits between your last judgment and your next filing. The clock the Commonwealth does keep runs the other way: Probate and Family Court Standing Order 1-06 puts a Complaint for Modification on the eight month track, the maximum time in which the case should be tried, settled or dismissed. Which test you must meet depends on which chapter made your order. Chapter 208 section 28, for parents who were divorced, wants a material and substantial change in the circumstances of the parties and modification that is necessary in the children's best interests. Chapter 209C section 20, for parents who were never married to each other, wants a substantial change in the circumstances of the parties or the child, and modification in the child's best interests. You file Form CJ-D 104, Complaint for Modification, in the division that issued the judgment, pay $50, and add $5 for each summons. Because this is a complaint rather than a motion, you are the plaintiff whatever label you carried in the original case. Attorney review of your filing is available through DocDraft.

What is prompting the change to your custody order?

DocDraft provides document preparation, not legal advice.

How do I change a child custody order in Massachusetts?

File a Complaint for Modification, Form CJ-D 104, in the Probate and Family Court division that issued your judgment. State in the complaint what has changed since that date and what you want changed. The filing fee is $50, plus $5 for each summons you need served.

Is there a waiting period to modify custody in Massachusetts?

No. Massachusetts imposes no waiting period and no time bar before a parent may file a Complaint for Modification. General Laws chapter 208 section 28 authorizes a modifying judgment upon a complaint after a divorce without attaching any minimum interval, and no section of chapter 208 or 209C sets one.

How much notice must a Massachusetts parent give before moving out of state with a child?

Massachusetts sets no notice period in days. General Laws chapter 208 section 30 instead prohibits removing a covered child out of the Commonwealth without consent, or without a court order granted upon cause shown. If the child is of suitable age to signify consent, it is the child's consent the statute requires.

Which court changes a custody order in Massachusetts?

The Probate and Family Court Department of the Trial Court, in the division where the judgment was originally issued. Standing Order 1-06 assigns a Complaint for Modification to the eight month track, and schedules a Case Management Conference no sooner than thirty days after the return of service or answer is filed.

Massachusetts custody modification at a glance

Changing child custody in Massachusetts means filing a new complaint asking the Probate and Family Court that issued your existing custody or parenting time order to change it, because something significant has changed since the judge signed it. Two features set the Commonwealth apart. First, the standard is written twice. General Laws chapter 208 section 28 governs orders out of a divorce and demands a material and substantial change in the circumstances of the parties, plus modification being necessary in the children's best interests. Chapter 209C section 20 governs orders between parents who were never married and asks only for a substantial change in the circumstances of the parties or the child. Second, no waiting period gates your filing, but Standing Order 1-06 puts the case on an eight month disposition track once it is filed.

A move across the state line with a teenager who has a say

Suppose your fifteen year old has lived under a Probate and Family Court judgment since a divorce four years ago, and you now want to move for a job across the state line. Because chapter 208 section 30 asks for the consent of a child of suitable age to signify it, your teenager's own position is not merely persuasive here, it is what the statute asks for first, with both parents' consent the fallback for a younger child. If consent is not there, you ask the court to order otherwise upon cause shown. Separately you would file Form CJ-D 104 to change the parenting time schedule the move breaks, show a material and substantial change in the circumstances of the parties, and expect the eight month track. Attorney review of your filing is available through DocDraft.

Relevant Laws

M.G.L. c. 208, s. 28 (modifying a custody judgment after a divorce)

Provides that upon a complaint after a divorce the court may modify its earlier judgment as to the care and custody of the minor children, provided it finds a material and substantial change in the circumstances of the parties and that the judgment of modification is necessary in the best interests of the children. It fixes no waiting period.

M.G.L. c. 208, s. 30 (removal of a child from the Commonwealth)

Bars removing a minor child of divorced parents, who is a native of or has resided five years in the Commonwealth and whose custody a probate court governs, out of the Commonwealth without the child's consent if of suitable age to signify it, or without both parents' consent if younger, unless the court upon cause shown otherwise orders.

M.G.L. c. 209C, s. 20 (modifying custody between parents who were not married)

Gives the court continuing jurisdiction to modify judgments of support, custody or visitation, and provides that no modification concerning custody or visitation may be granted unless the court finds a substantial change in the circumstances of the parties or the child and finds modification to be in the child's best interests.

M.G.L. c. 209B, s. 3 (affidavit required with your first pleading)

Requires every party in any custody proceeding to file an affidavit with their first pleading giving the child's present address, every address for the two years before filing, the parties to any custody case in that period, and any prior custody proceeding anywhere, with certified copies attached and sanctions for non-compliance.

Probate and Family Court: request to change a custody or parenting time order

The Trial Court's own how-to page for this situation. It names Form CJD 104 as the pleading, prints the $50 complaint fee and the $5 summons fee, directs filing in the division that issued the judgment, and notes that the filing parent becomes the plaintiff regardless of the original case.

Regional Variances

Massachusetts custody modification levers at a glance

Waiting period before you may file

None. Thirteen waiting period phrasings were scanned across fifteen custody sections of General Laws chapters 208 and 209C and returned zero hits. Chapter 208 section 28 authorizes a modifying judgment upon a complaint after a divorce without attaching any interval. There is no elapsed time trigger and no heightened endangerment showing keyed to one.

The clock that does exist

It runs after filing, not before. Probate and Family Court Standing Order 1-06 assigns a Complaint for Modification to the eight month track, described as the maximum time in which a case should be tried, settled or dismissed, with an express carve out for extraordinary cases. A Complaint for Divorce sits on the longer fourteen month track.

Standard to change a final order

Written twice. Chapter 208 section 28 requires a material and substantial change in the circumstances of the parties plus modification being necessary in the children's best interests. Chapter 209C section 20 requires a substantial change in the circumstances of the parties or the child plus modification in the child's best interests. The words material, of the child, and necessary differ between them.

Relocation mechanism

Permission first, not notice then object. Chapter 208 section 30 forbids removal of a covered child out of the Commonwealth absent consent or a court order upon cause shown, so silence never clears a move and there is no objection window to run. No notice period in days appears anywhere, and no mileage threshold exists. The trigger is the state line.

Whose consent the move needs

The child's own, if the child is of suitable age to signify consent. Both parents' consent is the fallback the statute reserves for a younger child. Section 30 also limits itself on its face to a child of divorced parents who is a native of or has resided five years in the Commonwealth and whose custody a probate court governs.

Court

The Probate and Family Court Department of the Trial Court, filed in the division that issued the judgment. For an order made elsewhere, the Massachusetts Child Custody Jurisdiction Act at General Laws chapter 209B decides whether a court here may modify, rather than the later uniform act.

Forms

Form CJ-D 104, Complaint for Modification, face stamped 1/22/2020, is the contested pleading. It names the prior judgment by date at item 2, the changes in circumstance at item 3, and the relief sought at item 4. The agreed route uses CJD 124, CJD 311 and CJD 446. CJD 400 changes a temporary order instead of a judgment.

Filing fee

$50 for a Complaint for Modification or a Joint Petition for Modification covering child support, custody and parenting time, with each summons an added $5 and the surcharge column reading no fee for that row. A post judgment removal is billed separately at $50, and modification of non child issues at $150. Confirm the total with the Register.

Procedural screen

An affidavit, not an adequate cause hearing gate. Chapter 209B section 3 requires every party in any custody proceeding to file a disclosure affidavit with their first pleading, covering two years of the child's addresses and every prior custody case anywhere, with certified copies attached. Adequate cause returns zero hits across the custody sections of chapters 208 and 209C.

Temporary relief while you wait

Chapter 208 section 28A is specific to the pendency of a modification action and sets a heavier bar than the final judgment does. Every temporary care and custody order must carry specific findings clearly demonstrating the injury, harm or damage reasonably expected without relief, and an order made without advance notice lasts no more than five days.

Child's wishes

No statutory age, and no maturity based preference factor either. Chapter 208 section 31 states an equal parental rights plus happiness and welfare test with no enumerated factor list. The scans for twelve, fourteen, sixteen, reasonable preference and wishes of the child all returned zero across these chapters.

Co-parenting course

Discretionary on a modification. Standing Order 3-23 orders the Two Families Now course for four new case types, and a Complaint for Modification is not one of them, though a judge may order it in a post judgment case with disputed custody or parenting time. The course is four hours online at $49 per parent.

Suggested Compliance Checklist

Confirm which chapter governs your order

Before you draft anything days after starting

Find your judgment and note whether it issued in a divorce or a parentage case. Chapter 208 section 28 and chapter 209C section 20 use different words, and the chapter 209C wording also reaches a change in the child's circumstances. Attorney review of your filing is available through DocDraft.

Assemble dated proof of the change

Before you file days after starting

Collect records tied to dates after the judgment: school reports, work schedules, medical notes, messages. Item 3 of Form CJ-D 104 is where the changes in circumstance go, and the judgment date you enter at item 2 is the line everything is measured from.

Re-read the removal rule if a move is in play

Before you commit to any move date days after starting

Chapter 208 section 30 is a consent or court order rule, not a notice countdown, so there is no number of days to run down. Work out whose consent it asks for in your situation, and note that a post judgment removal is a separate pleading with its own $50 fee.

Draft the Complaint for Modification

Once your evidence is assembled days after starting

Complete Form CJ-D 104. Identify the court and the date of the judgment at item 2, set out each change in circumstance at item 3, and state exactly how you want the judgment modified at item 4. You sign as plaintiff even if you were the defendant originally.

Draft the care or custody disclosure affidavit

Same day you file the complaint days after starting

Chapter 209B section 3 requires this with your first pleading. List the child's present address, every address in the two years before filing, the parties to any custody case in that period, and any prior custody proceeding anywhere, then attach certified copies of those pleadings.

File with the Probate and Family Court and pay

Promptly, since the track starts at filing days after starting

File in the division that issued your judgment. Pay the $50 Complaint for Modification fee and $5 for each summons. The surcharge column for this row reads no fee, so ask the Register what your total comes to before you write the check.

Serve the other parent and file the return

By the court's service deadline days after starting

Have the summons and complaint served on the other parent, then file the return of service. That return, or an answer, objection or counterclaim, is what prompts the Register to schedule a Case Management Conference, set no sooner than thirty days after the filing.

Keep following the current order until a judge changes it

Every day until the new judgment enters days after starting

Departing from the existing order is an enforcement problem rather than a modification, and it can count against you. If you need interim relief, chapter 208 section 28A requires specific findings of expected injury, harm or damage, and an order made without notice lasts five days.
