Custody in Connecticut.
The starting point the law actually sets, what the judge has to weigh, and the deadlines that catch people out.
See a different stateConnecticut
There is a presumption, but only where the parents agree. Conn. Gen. Stat. § 46b-56a(b): "There shall be a presumption, affecting the burden of proof, that joint custody is in the best interests of a minor child where the parents have agreed to an award of joint custody or so agree in open court at a hearing for the purpose of determining the custody of the minor child or children of the marriage. If the court declines to enter an order awarding joint custody pursuant to this subsection, the court shall state in its decision the reasons for denial of an award of joint custody." If you and the other parent do not agree, no presumption applies at all — and nothing in Connecticut law presumes equal parenting time. Separately, § 46b-56b creates a presumption in favor of a parent over a non-parent: in a custody dispute between a parent and a nonparent, it is presumed to be in the child's best interest to be in the parent's custody, rebuttable by showing that parental custody would be detrimental to the child. Section 46b-56(c) closes with the reminder that "[t]he court is not required to assign any weight to any of the factors that it considers, but shall articulate the basis for its decision."
Use the state’s own words
Connecticut uses "custody," "legal custody," "physical custody" and "visitation," but the operative statute also frames the decision as assigning "parental responsibility." Conn. Gen. Stat. § 46b-56(a) says the court "may assign parental responsibility for raising the child to the parents jointly, or may award custody to either parent or to a third party." Section 46b-56a is titled "Joint custody. Definition. Presumption. Conciliation. Parental responsibility plan. Modification of orders."
How Connecticut decides
Decisions against where the child lives
Section 46b-56a(a) defines joint custody as "an order awarding legal custody of the minor child to both parents, providing for joint decision-making by the parents and providing that physical custody shall be shared by the parents in such a way as to assure the child of continuing contact with both parents." So legal custody is decision-making authority and physical custody is where the child lives — but note the definition of joint custody in Connecticut bundles the two together, and "shared" physical custody means continuing contact, not a 50/50 count of nights. Separately, Conn. Gen. Stat. § 45a-606 provides that the father and mother of every minor child are joint guardians of the person of the minor with equal powers, rights and duties.
What the judge must weigh
(c) In making or modifying any order as provided in subsections (a) and (b) of this section, the court shall consider the best interests of the child, and in doing so, may consider, but shall not be limited to, one or more of the following factors:
- (1) The physical and emotional safety of the child;
- (2) the temperament and developmental needs of the child;
- (3) the capacity and the disposition of the parents to understand and meet the needs of the child;
- (4) any relevant and material information obtained from the child, including the informed preferences of the child;
- (5) the wishes of the child's parents as to custody;
- (6) the past and current interaction and relationship of the child with each parent, the child's siblings and any other person who may significantly affect the best interests of the child;
- (7) the willingness and ability of each parent to facilitate and encourage such continuing parent-child relationship between the child and the other parent as is appropriate, including compliance with any court orders;
- (8) any manipulation by or coercive behavior of the parents in an effort to involve the child in the parents' dispute;
- (9) the ability of each parent to be actively involved in the life of the child;
- (10) the child's adjustment to his or her home, school and community environments;
- (11) the length of time that the child has lived in a stable and satisfactory environment and the desirability of maintaining continuity in such environment, provided the court may consider favorably a parent who voluntarily leaves the child's family home pendente lite in order to alleviate stress in the household;
- (12) the stability of the child's existing or proposed residences, or both;
- (13) the mental and physical health of all individuals involved, except that a disability of a proposed custodial parent or other party, in and of itself, shall not be determinative of custody unless the proposed custodial arrangement is not in the best interests of the child;
- (14) the child's cultural background;
- (15) the effect on the child of the actions of an abuser, if any domestic violence, as defined in section 46b-1, has occurred between the parents or between a parent and another individual or the child;
- (16) whether the child or a sibling of the child has been abused or neglected, as defined respectively in section 46b-120; and
- (17) whether the party satisfactorily completed participation in a parenting education program established pursuant to section 46b-69b.
The court is not required to assign any weight to any of the factors that it considers, but shall articulate the basis for its decision.
What the child wants
Yes, with no statutory age. Factor (4) of § 46b-56(c) directs the court to consider "any relevant and material information obtained from the child, including the informed preferences of the child." The word that does the work is "informed" — the judge is weighing whether the child's stated preference is genuinely the child's and genuinely reasoned, which is also why factor (8) asks about a parent manipulating or coercing the child into the dispute. Section 46b-57 separately addresses the preference of the child where a third party intervenes.
Where there has been violence or abuse
Conn. Gen. Stat. § 46b-56(c)(15) requires the court to consider "the effect on the child of the actions of an abuser, if any domestic violence, as defined in section 46b-1, has occurred between the parents or between a parent and another individual or the child," and § 46b-56(c)(16) covers whether the child or a sibling has been abused or neglected as defined in § 46b-120. Public Act 21-78 revised the domestic violence definition and the custody statutes. We did not find, and so are not claiming, a Connecticut statutory presumption against custody for a parent who has committed domestic violence — that is a real difference from states like Alaska, Idaho, Kentucky and Oregon.
The paperwork and the people
The parenting plan
Connecticut does not require every parent to file a written parenting plan the way Washington, Oregon, Tennessee or Nebraska do. Section 46b-56a is titled in part "Parental responsibility plan," but we could not confirm the exact filing requirement from an official source, so treat that as an open question. The forms the Judicial Branch actually requires to open a custody or visitation case are listed at https://www.jud.ct.gov/forms/grouped/family/custody.htm — the core ones are the Custody/Visitation Application (JD-FM-161), Order to Attend Hearing and Notice to Respondent (JD-FM-162), Notice of Automatic Orders (JD-FM-158), Affidavit Concerning Children (JD-FM-164) and an Appearance (JD-CL-12).
If the court appoints someone to look into it
The Connecticut Practice Book, the rules governing family cases, provides for both roles: § 25-62 (Appointment of guardian ad litem) and § 25-62A (Appointment of attorney for a minor child), as catalogued in the Judicial Branch's own research guide on child custody actions. We could not confirm from an official source exactly how the fee is allocated between the parents, so treat cost as something to ask the court about at the time of appointment.
Moving away
What you must do before you move
Conn. Gen. Stat. § 46b-56d, which applies after judgment. In any proceeding arising after a judgment awarding custody, involving the relocation of either parent with the child, "where such relocation would have a significant impact on an existing parenting plan, the relocating parent shall bear the burden of proving, by a preponderance of the evidence, that (1) the relocation is for a legitimate purpose, (2) the proposed location is reasonable in light of such purpose, and (3) the relocation is in the best interests of the child." Subsection (b) lists what the court considers: each parent's reasons for seeking or opposing the relocation; the quality of the relationships between the child and each parent; the impact on the quantity and quality of the child's future contact with the non-relocating parent; the degree to which the relocating parent's and child's life may be enhanced economically, emotionally and educationally; and the feasibility of preserving the relationship through suitable visitation arrangements. There is no mileage trigger and no fixed notice period in the statute — the trigger is whether the move would significantly disrupt the existing parenting plan.
Later on
If you were never married
Custody and visitation between parents who were never married are handled under Conn. Gen. Stat. § 46b-61 ("Orders re children where parents live separately"), and the same § 46b-56(c) best-interests factors apply. Parentage itself is governed by the Connecticut Parentage Act (Public Act 21-15, codified beginning at § 46b-450), which defines "parentage" as "the legal relationship between a child and a parent of the child" (§ 46b-451(15)). A father who is not a legal parent needs parentage established before a custody order can run in his favor.
The single most important thing to know in Connecticut: the joint-custody presumption only exists if you both agree to joint custody. If you are fighting about it, there is no thumb on the scale in either direction, and the judge decides from the seventeen factors. The second surprise is that the statute expressly tells the judge she does not have to give any of those seventeen factors any particular weight — she only has to explain her reasoning. That is why Connecticut custody outcomes look less predictable than the long factor list suggests.
What we could not confirm
- Connecticut's own statute website (cga.ct.gov) would not accept a secure connection while we were working, so everything here comes from the Connecticut Judicial Branch's official law library research guides, which quote the statutes word for word and are dated 2025-2026. Two things we could not pin down: whether mediation is required before a contested custody hearing (Connecticut does require a parenting education program under § 46b-69b, which is a different thing), and the exact statutory standard for modifying a custody order. Connecticut courts generally require a material change in circumstances, but we would rather you confirm that with the clerk or a lawyer than take an unverified number from us. We also could not confirm whether a written "parental responsibility plan" must be filed, or who pays for a guardian ad litem.
- 2 official pages we tried to read refused automated access. We did not try to get around that, so some detail above was read from a different official source — a published court opinion quoting the statute, or the court’s own forms and instructions.
