Custom Motion to Modify Divorce Decree Form for Post-Judgment Changes in Support or Custody
Direct Answer
A motion to modify divorce decree form asks the court that issued a final decree of dissolution to change a post-judgment provision of the order: child custody, parenting time, child support, or spousal support. The moving party must show a substantial change in circumstances since the original order, with the threshold set by state statute. The full document body is below in attorney-grade form, with the California Family Code section 3087 custody scaffold, the section 4326 retirement scaffold, and a side-by-side state-track matrix covering Texas, Florida, and New York.

Motions to Modify Divorce Decree Form We Draft, From Motion to Modify Custody to Spousal Support Review
A motion to modify custody is the most frequently filed post-judgment motion in family law practice. Legal Tank drafts the motion as a stand-alone filing or as one of three companion motions inside the same post-judgment packet: custody, support, and alimony. Each track has its own statutory threshold, its own evidentiary load, and its own proposed order shape. The movant decides which tracks to file. The court rules on what is in front of it.
For the dispositive companion when the post-judgment fight also implicates discovery sanctions or a parallel enforcement action, see drafting service for a motion for sanctions targeting discovery abuse and bad-faith conduct for the pretrial misconduct vehicle, and attorney-prepared motion for contempt of court for enforcing orders against a noncompliant party for the enforcement work that often shares a docket with a post-judgment modification.
Track
Child Custody Modification
Legal Tank drafts the post-judgment motion to modify legal custody, physical custody, parenting time, or decision-making authority. The motion identifies the substantial change in circumstances since the existing order, attaches the supporting declaration, and lodges a proposed amended parenting plan that the court can sign.
Fam. Code 3087 / TFC 156.101 / Fla. Stat. 61.13 / DRL 240
Track
Child Support Modification
Legal Tank drafts the post-judgment motion to modify child support, including the updated income and expense statement, the guideline worksheet, and the requested deviation findings. The motion shows the income deviation or guideline shift that crosses the modification threshold in your state.
Fam. Code 4053 / TFC 156.401 / Fla. Stat. 61.14
Track
Spousal Support Modification
Legal Tank drafts the post-judgment motion to modify spousal support, terminate alimony on cohabitation, or step the support down on retirement. The motion plots the material change in need or ability to pay and confronts any non-modification clause inside the marital settlement agreement on the face.
Fam. Code 4326 / TFC 156 / Fla. Stat. 61.14 / DRL 236
Inside a Motion to Modify Parenting Plan and the Substantial Change Threshold
A motion to modify parenting plan is the narrowest of the three custody tracks. It targets the weekly schedule, the holiday and vacation rotation, the decision-making allocation on health and education, and the right-of-first-refusal provisions inside the existing parenting plan. The motion does not change legal or physical custody. The court applies the best-interest-of-the-child standard to the requested schedule changes after the substantial-change gate is cleared.
The most common record cite for a parenting plan modification is a documented relocation by either parent, a work-schedule shift that makes the existing parenting time impossible, the child reaching an age where school and activity schedules outgrow the original plan, or a long-standing de facto deviation from the original schedule that the parties want the court to formalize. Each ground attaches different documentary evidence in the supporting declaration.
The deliverable Legal Tank drafts for a parenting plan modification is a four-document packet: the motion to modify with grounds pleaded, the supporting declaration with documents and exhibits, the proposed amended parenting plan laid out week by week, and the proposed order. Your engaging counsel files, serves, and presents the packet at the noticed hearing.

How a Motion to Modify Divorce Decree Moves From Substantial-Change Showing to Signed Amended Order
A motion to modify divorce decree rides on three documents: the motion itself, the supporting declaration that sets out the substantial-change facts under penalty of perjury, and the proposed amended order the court can sign at the hearing. The procedural shape is the same across states; only the controlling statute and the timing rule change. The state matrix above maps the specific threshold for California, Texas, Florida, and New York. The on-page form below is the California backbone, with the bracketed jurisdictional fields keyed for cross-state use.
The post-judgment hearing is shorter than the original dissolution trial. The court is not deciding custody or support from scratch. It is deciding whether the moving party met the substantial-change burden, and if so, whether the requested modification serves the best interest of the child or the appropriate post-divorce support standard. Tight motions, complete declarations, and signed-ready proposed orders win these hearings.

_______________________________________
[Attorney Name], Esq.Six steps from blank form to filed motion
Each step corresponds to a section of the on-page form. Caption errors and substantial-change documentation gaps are the two ways a post-judgment motion fails on the papers without ever reaching the merits of the requested modification.
- 1
Copy the on-page form into your working document
Paste the motion body below into a working document. The bracketed fields (caption, case number, judge, decree filing date, the substantial-change paragraph, witness identifications, requested modified order language) are the only sections that need editing. The grounds scaffold and the verification scaffold stay intact across cases in the same state track.
- 2
Mirror the caption from the original divorce decree
Caption, parties, case number, and original judge carry forward from the decree of dissolution. Most state systems route the post-judgment motion back to the original case number rather than opening a new matter. Local rules vary on whether the motion lands on the original judge's calendar or rotates through the post-judgment department.
- 3
Plead the substantial change with record cites
Substantial change in circumstances is the gate. Each fact gets a record cite. Income shift: attach paystubs, tax returns, employment letter, or termination notice. Relocation: attach lease or purchase contract, school enrollment confirmation, employer transfer letter. Health or safety: attach medical records, police reports, CPS findings, or therapist declarations. Generic averments about change without supporting documents draw a tentative ruling to deny.
- 4
Run the meet-and-confer where it is required
California local family law rules in most counties require a documented meet-and-confer attempt on parenting plan modifications before the motion is set for hearing. Texas does not require it pre-motion but the court will route the parties through mediation under Family Code section 153.0071 before trial. Document the meet-and-confer attempt in the supporting declaration. A failed attempt is not a procedural defect; an undocumented attempt is.
- 5
Attach the proposed order or proposed parenting plan
Always attach the proposed amended order. Where parenting time is at issue, attach a proposed parenting plan with weekly, holiday, and summer schedules laid out by week and month. Where support is at issue, attach the updated guideline worksheet and a proposed support order with new monthly amounts, payment dates, and method of payment. The judge signs what is in front of them.
- 6
Have a family-law litigator finalize before filing
Post-judgment fights are easier to lose than the original divorce. Send the draft through Legal Tank intake so a family-law litigator pressure-tests the substantial-change showing, the declaration, the proposed parenting plan, and the venue choice for your state's calendaring rules. The motion is then ready for your engaging counsel to sign and file.
Where post-judgment modification intersects other motion work
A motion to modify rarely travels alone. It often accompanies a contempt motion when the opposing party has failed to comply with the existing order, an enforcement motion when arrears need to be reduced to judgment, or a motion to vacate when the original decree was procured by fraud or mutual mistake. For the parallel filings, see attorney-drafted motion to enforce family court orders and judgment provisions and attorney-drafted motion to vacate judgment under Rule 60 and Family Code section 2122. The procedural how-to that frames the broader filing posture sits at drafting a motion in court from caption to certificate of service.
The dispositive companions that often share a docket entry with a post-judgment modification include inside a motion for reconsideration template and the sections courts expect to see, building a motion for summary judgment template that tracks Rule 56 requirements, and anatomy of a motion for default judgment template and how each section functions.
For the procedural umbrella that places post-judgment modification motions inside the family-law pretrial motion family, see lawyers asking what is a pretrial motion use these filings to shape the trial record, and the broader umbrella at defining what is a motion in court and how written requests move a case forward. For the pro-se track, pro se roadmap on how to file a motion in court without an attorney walks through the local-rules research the self-represented filer needs. The general procedural how-to is at steps for how to file a court motion from drafting through the hearing. For a drafting-pair service on amended pleadings, see drafting service for a motion to amend pleadings after discovery reveals new claims, and for the parallel dispositive template family, see building a motion to dismiss template that hits Rule 12(b)(6) on the face.
