How to Modify Child Custody in Indiana

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

Indiana makes you point at a numbered factor. Changing child custody here means asking the Indiana circuit or superior court that issued your existing custody or parenting time order to change it because something significant has happened since that order was entered. Indiana Code 31-17-2-21(a) sets two requirements that must both be satisfied: the modification is in the best interests of the child, and there is a substantial change in one or more of the factors the court weighs under Indiana Code 31-17-2-8. That is narrower than a general change in circumstances. The change has to sit inside a listed factor, such as the child's adjustment to home, school and community, the mental and physical health of everyone involved, or a pattern of domestic or family violence. Subsection (c) then limits your evidence, because the court shall not hear evidence about anything occurring before your last custody proceeding unless it relates to a change in those same factors. On timing Indiana is permissive. A scan of all 34 live sections of Indiana Code 31-17-2 turns up no waiting period, no minimum interval after the last order, no required affidavit and no adequate cause screen, so you may file as soon as you can show the substantial change. The twelve month clock Indiana parents hear about sits in Indiana Code 31-16-8-1 and governs child support, not custody. Moving with the child runs on a separate chapter, Indiana Code 31-17-2.2, with its own filing deadline, its own content checklist and a burden that shifts partway through the hearing. Attorney review of your filing is available through DocDraft.

How do I modify a child custody order in Indiana?

File a petition to modify in the Indiana circuit or superior court that issued your order, under the same cause number. Indiana Code 31-17-2-21 requires two showings at once: a substantial change in one or more of the best interest factors listed in Indiana Code 31-17-2-8, and that the modification serves the child.

Is there a waiting period to modify custody in Indiana?

No. Indiana Code 31-17-2 sets no waiting period, no minimum interval after the last order and no affidavit screen, so a parent may petition whenever the substantial change can be shown. The twelve month requirement in Indiana Code 31-16-8-1 reaches child support modifications only, never custody or parenting time.

How much notice must an Indiana parent give before relocating with a child?

Indiana Code 31-17-2.2-3 requires the relocating parent to file and serve a notice of intent to move not later than 30 days before the intended relocation, or not more than 14 days after becoming aware of the relocation, whichever is sooner. The other parent then gets 20 days to respond.

Which Indiana moves are exempt from the relocation notice?

Under Indiana Code 31-17-2.2-1(b) notice is excused when a prior court order already addresses relocation, or when the move shortens the distance between the two homes, or lengthens it by no more than 20 miles and still allows the child to remain enrolled in the current school.

Indiana custody modification at a glance

Modifying child custody in Indiana means asking the circuit or superior court that issued your existing custody or parenting time order to change it because something significant has happened since it was entered. Indiana words the test unusually tightly. Indiana Code 31-17-2-21(a) permits a modification only where it is in the child's best interests and there is a substantial change in one or more of the enumerated factors in Indiana Code 31-17-2-8, so a parent has to name the factor rather than argue that life is simply different now. Subsection (c) then bars evidence about events predating the last custody proceeding unless it bears on a change in those factors. Indiana attaches no waiting period and no affidavit screen to any of this. Relocation runs on its own chapter, with its own filing deadline and a burden that shifts.

A 12 mile Indiana move that still needs notice

Picture an Indianapolis parent with primary physical custody taking a job in Greenwood and moving 12 miles south, across a school boundary. The 20 mile figure in Indiana Code 31-17-2.2-1(b) does not excuse that move, because the exemption also requires the child to remain enrolled in the current school, and this child would transfer. So the parent files a notice of intent to move with the clerk of the issuing court and serves it at least 30 days ahead, listing the new address, every telephone number, the move date and the specific reasons. The other parent has 20 days to respond. At the hearing the moving parent must prove good faith and a legitimate reason, and the burden then shifts. Attorney review of your filing is available through DocDraft.

Relevant Laws

Ind. Code 31-17-2-21 (modification of child custody order)

Provides that the court may not modify a child custody order unless the modification is in the best interests of the child and there is a substantial change in one or more of the section 8 factors. Subsection (c) bars evidence on matters occurring before the last custody proceeding unless it relates to a change in those factors.

Ind. Code 31-17-2-8 (the best interest factors you must point to)

Lists the nine factors with no presumption favoring either parent, including the age and sex of the child, the wishes of the parents, the wishes of the child with more consideration at fourteen, the child's adjustment to home, school and community, and evidence of a pattern of domestic or family violence.

Ind. Code 31-17-2.2-1 (notice of intent to move, and the exemptions)

Requires a relocating individual to file a notice of intent to move with the clerk of the court that issued the order, and exempts a move already addressed by a prior order, or a move that shortens the distance or lengthens it by not more than twenty miles while letting the child stay in the current school.

Ind. Code 31-17-2.2-3 (the notice deadline and the eight content items)

Sets the dual deadline of not later than thirty days before the intended relocation or not more than fourteen days after becoming aware of it, whichever is sooner, and lists the content the notice must carry, including the twenty day response warning and the statement that existing orders remain in effect.

Ind. Code 31-17-2.2-5 (response, hearing and the burden shift)

Gives the nonrelocating parent twenty days to file one of three prescribed responses, requires a full evidentiary hearing on either party's request, places the burden on the relocating individual to prove good faith and a legitimate reason, then shifts it to the nonrelocating parent on best interest, and permits the move if no response is filed.

Regional Variances

Indiana custody modification levers at a glance

Waiting period before you may file

None. No section of Indiana Code 31-17-2 sets a waiting period or a minimum interval after the last order. The only year figures in the chapter sit in Indiana Code 31-17-2-8.3(b), which presumes supervised parenting time for at least one year and not more than two after a domestic or family violence crime.

Standard to change the order

Two requirements together under Indiana Code 31-17-2-21(a): the modification is in the best interests of the child, and there is a substantial change in one or more of the Indiana Code 31-17-2-8 factors, plus the Indiana Code 31-17-2-8.5 de facto custodian factors where they apply. Naming the factor matters.

Evidence restriction

Indiana Code 31-17-2-21(c) directs that the court shall not hear evidence on a matter occurring before the last custody proceeding between the parties unless the matter relates to a change in the best interest factors. The date of that last proceeding becomes the cutoff for your record.

Relocation mechanism

Notice then object, with the notice filed at the clerk's office as well as served. The nonrelocating parent shall file a response under Indiana Code 31-17-2.2-5(a), and subsection (g) permits the move where no response is filed. Indiana Code 31-17-2.2-6 lets the court restrain a move or order the child back.

Relocation notice deadline

Not later than 30 days before the intended relocation, or not more than 14 days after the relocating individual becomes aware of the relocation, whichever is sooner, under Indiana Code 31-17-2.2-3. Nonparties get the notice by registered or certified mail on the same dual deadline. Response window is 20 days.

Relocation trigger

Notice is the default for any change of residence. The 20 mile figure in Indiana Code 31-17-2.2-1(b) is an exemption ceiling, not a trigger, and it is conjunctive: the move must also let the child remain enrolled in the current school. There is no school district test and no other mileage figure in the chapter.

Court, form and fee

The Indiana circuit or superior court that issued the order, filed under the same cause number. No statute in either chapter prescribes a form, so the petition is drafted. Indiana Code 33-37-4-4 sets a $100 civil costs fee for filing a civil action, and no statute fixes a post decree modification fee, so confirm with the clerk.

Procedural screen and the child's wishes

No adequate cause screen and no required affidavit anywhere in either chapter. Mediation is discretionary and appears only in Indiana Code 31-17-2.2-1(d). On the child's wishes, fourteen under Indiana Code 31-17-2-8(3) only increases the weight given, and the in chambers interview under Indiana Code 31-17-2-9 is optional.

Suggested Compliance Checklist

Fix the date of your last custody proceeding

Before you draft anything days after starting

Pull your case history and identify the date of the last custody proceeding between you and the other parent. Indiana Code 31-17-2-21(c) makes that date the cutoff for evidence, so anything earlier only comes in if it relates to a change in the best interest factors.

Map your facts onto a numbered best interest factor

Before you file days after starting

Read the nine factors in Indiana Code 31-17-2-8 and assemble dated proof against the specific one that has substantially changed: school records, medical notes, work schedules, messages. Indiana requires a substantial change in a listed factor, so an unmatched grievance will not carry the petition.

Draft the petition to modify custody

Once your evidence is assembled days after starting

No Indiana statute prescribes a form. Draft a petition that names the order to be changed, identifies the factor that has substantially changed, sets out the facts and dates since the last proceeding, and states the custody or parenting time arrangement you want entered instead. Attorney review of your filing is available through DocDraft.

Draft the relocation notice if you are moving

At least 30 days before any move, or within 14 days of learning of it days after starting

Indiana Code 31-17-2.2-3 requires the intended address and mailing address, all telephone numbers, the move date, the specific reasons, whether you think parenting time needs revising, the 20 day response warning, the two petition statements, and a statement that existing orders remain in effect.

File with the clerk of the issuing court

Promptly, and before any planned move days after starting

File under the same cause number with the clerk of the circuit or superior court that issued your order. Indiana Code 33-37-4-4 sets a $100 civil costs fee for filing a civil action, and no statute fixes a separate post decree fee, so confirm the amount with that clerk before you go.

Serve the other parent under the Trial Rules

By the deadline in Indiana Code 31-17-2.2-3 where a move is involved days after starting

Serve a party in accordance with the Indiana Rules of Trial Procedure, and send the notice to a nonparty with rights to the child by registered or certified mail. Late service is a ground for a temporary order restraining the move under Indiana Code 31-17-2.2-6(a).

Prepare for mediation and the evidentiary hearing

Before your hearing date days after starting

The court may order mediation in a relocation dispute under Indiana Code 31-17-2.2-1(d), and shall hold a full evidentiary hearing on either party's request. Keep following your current order until a judge signs a new one, because every existing order stays in effect until it is modified.
