How long does a custody modification take in Connecticut?

The clerk sets the first court event when you file JD-FM-174, and it may be a hearing, a Case Date, or a Resolution Plan Date. Service must happen at least 12 days before it and proof of service at least 6 days before, so plan on several weeks minimum, longer if the move is contested.

Can a Connecticut parent move out of state with the child after judgment?

Conn. Gen. Stat. 46b-56d does not forbid it and sets no permission step. It allocates proof: if the move would significantly affect the existing parenting plan, the relocating parent must prove legitimate purpose, a reasonable destination, and best interests. Practice Book 25-5(a)(1) bars removal from Connecticut while a case is pending.

Do I need the other parent to agree to change custody in Connecticut?

No. Either parent can file JD-FM-174 alone, and Practice Book 25-26(b) lets either parent be cited or summoned to appear and show cause why orders of custody or visitation should not be modified. If you agree, Conn. Gen. Stat. 46b-56a(d) wants a proposed parental responsibility plan filed.

How does a Connecticut judge decide whether to change a custody order?

Conn. Gen. Stat. 46b-56(c) lists seventeen best interest factors, from the child's physical and emotional safety to each parent's willingness to encourage the other relationship. The court need assign no weight to any factor but must articulate the basis for its decision, and 46b-56(b) requires active involvement of both parents.

Do I have to attend a parenting class before my Connecticut custody motion?

Often yes, once per case. Conn. Gen. Stat. 46b-69b(b) directs the court to order participation in the parenting education program whenever a minor child is involved, unless the parties agree otherwise with court approval, the court finds it unnecessary, or they complete a comparable program. Completion is best interest factor seventeen.

What happens if a Connecticut judge requires a Request for Leave?

Practice Book 25-26(g) lets a judge order that any further motion to modify a final custody or visitation order be appended with a Request for Leave, form JD-FM-202, sworn to by the moving party. The other side has 10 days to object. If it objects, you must demonstrate probable cause that grounds exist.

Can a Connecticut custody order be changed while a parent is deployed?

Conn. Gen. Stat. 46b-56e(c) lets the court enter temporary modification orders during a deployment or mobilization that materially affects the deploying parent's ability to exercise parental rights, and gives those motions priority. But 46b-56e(b) blocks a final modification order until 90 days after the deployment ends, absent that parent's agreement.

How quickly can a Connecticut parent act if a child is in danger?

Conn. Gen. Stat. 46b-56f allows an application for an emergency ex parte order of custody, form JD-FM-222, where the applicant believes an immediate and present risk of physical danger or psychological harm exists. A sworn affidavit is required, and if relief is granted ex parte a hearing follows within 14 days.

How to Modify Child Custody in Connecticut

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

Connecticut settles the moving question with a burden of proof instead of a notice deadline, and that one choice shapes how a parent files here. Modifying child custody in Connecticut means asking the Superior Court that entered your existing custody or parenting time order to change it, because something significant has shifted since that order. Two things parents expect to find do not exist. There is no waiting period: Conn. Gen. Stat. 46b-56(a) lets the court make or modify a custody order at any time after the return day, and the custody sections of chapter 815j carry no clause barring or delaying a motion. There is also no relocation notice period and no distance threshold. Instead Conn. Gen. Stat. 46b-56d provides that where a move after judgment would have a significant impact on an existing parenting plan, the relocating parent bears the burden of proving, by a preponderance of the evidence, that the relocation is for a legitimate purpose, that the proposed location is reasonable in light of that purpose, and that the move is in the child's best interests. You file statewide form JD-FM-174, Motion for Modification, back into the same docket number, checking item 1(c) for custody or item 1(d) for parenting time, with the Affidavit Concerning Children, form JD-FM-164. The fee is $180 under Conn. Gen. Stat. 52-259c(a), and the statute says the court may waive it. One conditional step catches people out: under Practice Book 25-26(g) a judge may require a sworn Request for Leave, form JD-FM-202, before a further custody motion can proceed. 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 modify a child custody order in Connecticut?

File form JD-FM-174, Motion for Modification, in the Superior Court judicial district that entered your order, under the same docket number. Check item 1(c) for custody or item 1(d) for parenting time, attach the Affidavit Concerning Children (JD-FM-164), and pay the $180 fee set by Conn. Gen. Stat. 52-259c(a).

Is there a waiting period to modify custody in Connecticut?

No. Conn. Gen. Stat. 46b-56(a) lets the Superior Court make or modify a custody order at any time after the return day, and no section of chapter 815j delays a motion. The single clock, 46b-56e(b), stops a final order until 90 days after a parent's military deployment ends.

How much notice must a Connecticut parent give before moving with a child?

Connecticut fixes no advance notice period and no distance threshold. Conn. Gen. Stat. 46b-56d instead puts the burden of proof on the relocating parent where a move after judgment would significantly affect an existing parenting plan. That parent must prove legitimate purpose, a reasonable destination, and the child's best interests.

At what age does a Connecticut child choose which parent to live with?

At no fixed age. Conn. Gen. Stat. 46b-56(c)(4) makes the informed preferences of the child one of seventeen best interest factors, with no age attached, and 46b-57 asks only whether the child is of sufficient age and capable of forming an intelligent preference.

Connecticut custody modification at a glance

Changing child custody in Connecticut means asking the Superior Court that entered your existing custody or parenting time order to change it, because something significant has shifted since that order. Connecticut is unusual in what it leaves out. Conn. Gen. Stat. 46b-56(a) authorises the court to make or modify a custody order at any time after the return day, so there is no interval to sit through. The word mile does not appear anywhere in chapter 815j, so there is no distance that triggers a duty. What Connecticut legislated instead is an allocation of proof: under 46b-56d the parent who wants to relocate after judgment carries the burden, by a preponderance of the evidence, on legitimate purpose, a reasonable destination, and the child's best interests. The statutory substance of the test sits in 46b-56(b) and the seventeen best interest factors in 46b-56(c).

A Hartford job offer in Springfield, five months after judgment

Imagine a Connecticut judgment five months old, alternating weeks, and the parent in Hartford is offered a promotion that requires living near Springfield. Timing is not the obstacle, because Conn. Gen. Stat. 46b-56(a) permits a modification at any time and no distance threshold exists in chapter 815j. The obstacle is 46b-56d: the new commute would gut the alternating week schedule, so the relocating parent carries the burden by a preponderance on legitimate purpose, a reasonable destination, and best interests. That parent files JD-FM-174 marked After judgment with item 1(c) checked, documents the salary, the role, the school, and a proposed replacement schedule preserving the other parent's time, pays $180, and serves 12 days out. Attorney review of the filing is available through DocDraft.

Relevant Laws

Conn. Gen. Stat. 46b-56 (custody orders, modification at any time, best interest factors)

Lets the Superior Court make or modify any proper order on custody, care, education, visitation and support at any time after the return day, requires orders serving the child's best interests with active involvement of both parents, and lists the seventeen best interest factors including the informed preferences of the child.

Conn. Gen. Stat. 46b-56d (relocation after judgment, burden of proof)

Provides that where a relocation after a custody judgment would have a significant impact on an existing parenting plan, the relocating parent bears the burden of proving by a preponderance of the evidence a legitimate purpose, a reasonable proposed location, and the child's best interests. Sets no notice period and no distance threshold.

Conn. Gen. Stat. 46b-56e (custody and visitation orders for a deploying parent)

Bars the court from entering a final modification order until ninety days after a deploying parent's deployment or mobilization ends unless that parent agrees, while separately authorising priority temporary modification orders during the deployment where it materially affects that parent's ability to exercise parental rights.

Motion for Modification, Judicial Branch form JD-FM-174

The statewide Superior Court form. Carries separate checkboxes for modifying a custody order and a visitation or parenting time order, the substantial change in circumstances ground, the deploying parent ground, the clerk's hearing or Resolution Plan Date block, and the 12 day service and 6 day proof of service directions.

Connecticut Judicial Branch Court Fees schedule

Item 17 of the published schedule prices a post-judgment motion to modify any judgment in a family relations matter at $180, citing Conn. Gen. Stat. 52-259c(a). Item 16 is the separate $130 charge for a motion to open or set aside a family judgment, which is a different filing.

Regional Variances

Connecticut custody modification levers at a glance

Waiting period before you may file

None. Conn. Gen. Stat. 46b-56(a) permits the Superior Court to make or modify a custody order at any time after the return day. The custody sections of chapter 815j contain no clause barring, delaying or conditioning a motion on elapsed time, and no heightened endangerment showing is keyed to a clock.

The one clock that does exist

Conn. Gen. Stat. 46b-56e(b) stops the court from entering a final order modifying custody or visitation until ninety days after a deploying parent's deployment or mobilization ends, unless that parent agrees. It runs from the deployment ending, not from the order, and 46b-56e(c) still allows temporary orders meanwhile.

Standard to change an order

Conn. Gen. Stat. 46b-56(b) requires orders serving the child's best interests with active and consistent involvement of both parents, and 46b-56(c) supplies seventeen factors the court may weigh without assigning weight to any, while articulating its basis. The material change requirement itself is Connecticut case law rather than statutory text.

Relocation mechanism

A burden allocation, not a notice or permission procedure. Conn. Gen. Stat. 46b-56d puts the burden on the relocating parent, by a preponderance of the evidence, on legitimate purpose, a reasonable proposed location, and best interests, triggered where the move would have a significant impact on an existing parenting plan.

Relocation notice and distance

No advance notice period and no distance threshold. Practice Book 25-5(a)(1) bars permanently removing the child from Connecticut without written consent or a court order, but the automatic orders in 25-5 run only during the pendency of an action. Practice Book 25-5(a)(2) adds a 48 hour address notice after a move.

Court

The Superior Court, in the judicial district holding your case, filed back into the same docket number. Conn. Gen. Stat. 46b-56(a) speaks of a controversy before the Superior Court as to custody or care of minor children, subject to the jurisdictional provisions of chapter 815p.

Forms

JD-FM-174 Motion for Modification is the statewide form, with item 1(c) for custody and item 1(d) for visitation or parenting time. JD-FM-164 Affidavit Concerning Children rides with it. JD-FM-202 Request for Leave applies only if ordered. JD-FM-284 is the Custody Agreement and Parenting Plan.

Filing fee

$180 under Conn. Gen. Stat. 52-259c(a) for a post-judgment motion to modify a judgment in a family relations matter, and the Judicial Branch Court Fees schedule publishes the same figure. The statute adds that the fee may be waived by the court. A motion to open or set aside a family judgment is priced separately at $130.

Procedural screen

Conditional, and the condition is a judicial order. Practice Book 25-26(g) lets a judge require a Request for Leave sworn by the moving party before a further motion to modify a final custody or visitation order; the other party has 10 days to object, and on objection the mover must show probable cause that grounds exist.

Child's wishes

No numeric age. Conn. Gen. Stat. 46b-56(c)(4) counts any relevant and material information obtained from the child, including the child's informed preferences, as one factor among seventeen, and 46b-57 turns on whether the child is of sufficient age and capable of forming an intelligent preference.

Suggested Compliance Checklist

Pull the order and date the change

Before you file days after starting

Practice Book 25-26(e) makes every modification motion state the specific factual and legal basis and identify the outstanding order and its date. Find your order, write the date down, and assemble dated proof of what has shifted since: school records, work schedules, messages, medical notes.

Build the three part relocation showing

Before any planned move days after starting

If a move drives the request, Conn. Gen. Stat. 46b-56d makes you the party with the burden. Collect evidence on legitimate purpose, why that particular location is reasonable for that purpose, and the child's best interests, plus a workable replacement schedule for the other parent.

Check whether a Request for Leave was ordered

Before you draft days after starting

Practice Book 25-26(g) lets a judge require form JD-FM-202 to be appended to any further motion to modify a final custody or visitation order, sworn to by the moving party. Read your file for such an order, because the leave step runs on its own 10 day objection track.

Complete form JD-FM-174

As soon as your evidence is assembled days after starting

Mark After judgment, enter the judicial district, town and docket number, then check item 1(c) for custody or item 1(d) for visitation, which the form calls parenting time. State what the current order says and precisely what you are asking for, and select your ground at item 2.

Attach the affidavits your checkbox requires

With the motion, or at least 5 business days before the hearing days after starting

Item 1(d) parenting time requires the Affidavit Concerning Children, form JD-FM-164. Item 1(c) custody also requires a sworn Financial Affidavit, form JD-FM-6, filed at least five business days before the hearing, with a guidelines worksheet. Conn. Gen. Stat. 46b-56a(d) wants a proposed parental responsibility plan in a contested dispute.

File with the Superior Court clerk and pay $180

Promptly, because court events are set weeks out days after starting

File into the existing docket number in the judicial district holding your case. Conn. Gen. Stat. 52-259c(a) sets $180 for a post-judgment motion to modify a judgment in a family relations matter and provides that the fee may be waived by the court. The clerk completes the hearing block.

Serve 12 days out and file proof 6 days out

At least 12 days before your court event days after starting

The clerk's order on JD-FM-174 directs that a true and attested copy of the motion and order be served on the other party by a proper officer at least 12 days before the court event, with proof of service filed at least 6 days before. Missing either date moves your event.

Attend the court event with a written proposal

On the date the clerk assigns days after starting

Your event may be a hearing, a Case Date, or a Resolution Plan Date where you speak with Family Services before a judge considers any agreement or issues scheduling orders. Bring a specific written schedule with dates, times and exchange locations, and keep following the current order until a judge signs a new one.
