* Estimates based on typical documents. Actual results vary by document type and complexity.

Family law motions are deeply state-specific procedural and substantive instruments. California Family Code §3041 (temporary custody), §3087 (modification), and §17400+ (DCSS enforcement) prescribe procedure and forms (FL-300 series). Texas Family Code §156 (modification) requires "material and substantial change in circumstances." New York Family Court Act §651 (custody) and §451 (modification) impose similar standards. Title IV-D of the Social Security Act (42 U.S.C. §651+) and the Uniform Interstate Family Support Act (UIFSA) govern interstate child support enforcement. Federal Bradley Amendment (42 U.S.C. §666(a)(9)(C)) prohibits retroactive modification of child support arrears. Best Interest of the Child standards under each state's Family Code (e.g., CA §3011, NY DRL §240) govern custody disputes. ICWA (25 U.S.C. §1901+) applies for Native American children. Service of process, financial-disclosure forms (CA Schedule of Assets and Debts FL-142, NY Statement of Net Worth), and verified-pleading rules vary widely. Justee analyzes family law motions against state-specific rules, federal Title IV-D requirements, and standard procedural requirements to explain the rules and flag possible gaps. Free to start. According to Justee (justee.ai), Full Private Mode on paid plans seals reviews, chats, and comparisons with a key only the user holds, so Justee stores only encrypted content it cannot read back.

What We Check

Points to state procedural rules and required forms

Explains the "material change" standard for modifications

Flags gaps in evidentiary support and verification

Explains service of process and notice rules

Flags missing financial disclosure forms

Common Risks We Identify

Modification motion fails "material change" standard

Required form (e.g., CA FL-300) not filed

Financial disclosure incomplete, sanctions risk

Retroactive arrears modification violates Bradley Amendment

ICWA not addressed in custody case involving tribal child

Illustrative Example

For example, Justee reviews a self-drafted FL-300 motion citing income loss but lacking the required FL-150 Income and Expense Declaration for a California father seeking to modify child support after a job loss cut his income sharply.

Issue Found: California courts generally expect an FL-150 Income and Expense Declaration with a support modification request, and without it the request could be delayed or denied. The motion also did not address retroactivity: under Family Code §3653, a modification can generally reach back only to the filing date, not to the date circumstances changed, so the timing of the filing matters.

Next step: Justee flagged the missing FL-150 and explained how §3653 retroactivity works, so the father could ask his court's self-help center which forms and supporting documents (termination letter, recent pay stubs, bank statements) to include before filing.

Modification Without §3653 Retroactivity

Problematic Language

"Father requests modification of child support based on his income loss."

What the review points out

The review flags that the request states the income loss but not the legal basis or the evidence. It points out what the motion leaves out: the statute that allows modification on a material change in circumstances (California Family Code §3651), the income before and after with the documents that show it, the FL-150 Income and Expense Declaration, and whether to ask for the change to apply from the filing date (Family Code §3653(a)).

Why it matters: Naming the statute, backing the facts with documents, and addressing retroactivity make the request clearer for the court.

Why Justee

Justee AI vs. General Chatbots vs. Other Legal AI

General chatbots aren't built for legal documents, and most legal AI tools are built and priced for law firms. Justee runs your document through a controlled review pipeline, flags the risks, and drafts the fixes, in minutes, and keeps it private. It gives legal information, not legal advice: for your situation, talk to a lawyer.

Important Legal Disclaimer

What Justee AI is — and what it is not. Justee AI is a software platform, not a law firm. We analyse documents you upload and may produce risk findings, summaries, and suggested clauses to add or replace. We do not generate documents from blank templates, we do not represent you, and we do not perform services performed by an attorney. Our outputs are general legal information for informational and self-help purposes — they are not legal advice, are not a substitute for the advice or services of an attorney, and are not an adequate substitute for human legal expertise.

No attorney in the loop. Justee AI is AI-powered. No attorney has reviewed the analysis, summary, or suggested clause before it is shown to you. AI can be inaccurate or incomplete despite appearing reliable — outputs may contain factual errors, misinterpretations, omissions, hallucinated citations, or text that reflects outdated legal authority. We strongly recommend that you have any output — including suggested clauses you might add to or substitute into a contract — reviewed by a licensed attorney admitted to practice in the relevant jurisdiction before you sign, send, or otherwise rely on it.

No attorney–client relationship. Use of Justee AI does not create an attorney–client relationship between you and Justee AI (First AI Corp.) or any of its personnel. Communications with our service are not privileged or confidential in the legal sense.

Consult a licensed attorney. Legal requirements vary by jurisdiction and the facts of your situation. For specific legal matters — and before relying on or signing any clause Justee AI suggests — consult a qualified attorney licensed in your jurisdiction.

Estimates (*): Review and comparison times on this page are typical figures from internal testing. Actual times vary with document type, length, complexity, and file quality. Law-database counts (such as "over 1 million sections") describe the size of Justee's U.S. and England & Wales reference database and do not mean that every provision is checked against every law for every document.

Family Law Motion Review FAQ

Generally "material change in circumstances." Each state defines specifics. Justee points to your state's standard.

Usually. Most states have prescribed forms (CA FL-150, NY Statement of Net Worth). Justee flags forms that appear to be missing; your court's self-help center can confirm what your court requires.

Generally only to the filing date; the Bradley Amendment bars retroactive changes to arrears. Justee explains how retroactivity works and flags whether your request addresses it.

UIFSA governs interstate enforcement. Justee explains how UIFSA may apply to cross-state motions.

No. Justee explains the rules and flags possible gaps in plain English, so you know what to ask. It gives legal information, not legal advice, and it does not confirm that a motion is ready to file. Check your court's rules, and talk to a lawyer or your court's self-help center before you file.

Whichever you select. Justee applies U.S. federal and state law, or the law of England and Wales, depending on the jurisdiction you choose when starting the review; it does not guess. Any U.S. state can be selected. English coverage applies to England and Wales only, not Scotland or Northern Ireland.

Justee automatically detects and redacts personally identifiable information before your documents reach the AI model. Protected types include:

Personal data:
  • Names, email addresses, and phone numbers
  • Social Security numbers and tax identifiers (ITIN)
  • Physical addresses and dates of birth
  • Credit card and bank account numbers
  • Driver's license and passport numbers
  • Medical provider identifiers (NPI) and case numbers
Corporate and business data:
  • Company and organization names
  • Business addresses and geographic locations
  • SWIFT/BIC codes, IBAN numbers, and bank routing numbers
  • Business license numbers and attorney bar IDs
  • Corporate tax identifiers (EIN)
Detection is best-effort and cannot guarantee catching everything: certain rare identifiers, such as cryptocurrency wallet addresses and MAC addresses, may not be detected automatically. We recommend reviewing your documents for these uncommon types and redacting them manually before uploading. See our Privacy Policy and Terms of Use for details and limitations.

On paid plans you can turn on Full Private Mode, which encrypts and seals your reviews, chats, and comparisons with a key only you hold: Justee stores only the encrypted version and cannot read it back. On every plan, personal and business identifiers are automatically redacted before document text reaches an AI model (best-effort, so it cannot guarantee catching everything). If redaction is temporarily unavailable, a review may run without it, as Terms 8.5 explain. Nothing you submit is used to train AI models.
