Summary
Case Summary: In re Marriage of Kidder-Nguyen - The article reveals how divorce proceedings have become a digital battleground, where a spouse's monitored email or shared cloud account can silently expose every legal strategy before it's even filed. Illinois family law attorneys now advise clients to implement cybersecurity measures—encrypted communications, two-factor authentication, and device sweeps for hidden trackers—as essential litigation tactics, not optional precautions.

This article discusses legal strategy and tactics used by experienced family law attorneys in Illinois. Every case is unique. The strategies below may not apply to your situation. Consult with a licensed Illinois attorney before implementing any tactic.
Why This Checklist Exists: "In 15 years practicing family law in Cook County, I've seen unprepared clients lose winnable cases. One mother lost custody leverage. Why? She couldn't produce three years of tax returns. A father watched his business valuation spiral out of control. He hadn't secured financial documentation before filing. This checklist ensures you don't make those mistakes."
🔒 Security Note: Protecting sensitive family information is critical. Learn how SteeleFortress helps law firms and families safeguard their digital assets.
Strategy #1: Front-Load Your Document Gathering (30 Days Before Filing)
The Tactic: The month before you file determines everything. You either enter litigation from strength or scramble to catch up. Every document you secure now becomes ammunition later.
Why It Works:
- Forces you to identify evidence gaps early
- Prevents your spouse from hiding or destroying records
- Creates settlement leverage before negotiations begin
- Demonstrates preparation that impresses judges
Implementation:
- ☐ Gather financial records: Collect the last 3 years of tax returns, bank statements, and investment accounts. Request copies directly from your CPA and financial institutions. Your spouse may have already restricted access.
- ☐ Document digital assets: Locate cryptocurrency wallets, PayPal, Venmo accounts, NFTs, and online business accounts. Screenshot current balances with timestamps. Crypto values fluctuate dramatically.
- ☐ Secure sensitive communications: Use encrypted email like ProtonMail for all attorney correspondence. Your shared family Gmail account is discoverable.
- ☐ Change passwords immediately: Update access to bank accounts, email, social media, Amazon, and streaming services. Use a password manager like 1Password or LastPass. One client discovered her spouse monitored her email for six months before she filed.
- ☐ Screenshot critical evidence: Capture text messages, emails, and social media posts. Look for marital misconduct, hidden assets, or parenting concerns. Preserve metadata by using your phone's native screenshot function.
- ☐ Inventory marital property: Walk through your home with your phone camera. Open every drawer, closet, and safe. Document jewelry, art, collectibles, and electronics with serial numbers.
- ☐ Obtain credit reports: Pull reports from Equifax, Experian, and TransUnion. Identify unknown accounts or credit cards your spouse may have opened.
- ☐ Secure vital documents: Gather birth certificates, Social Security cards, passports, and marriage certificates. Include vehicle titles and property deeds. Store copies outside your home.
Strategy #2: Master the Required Illinois Filing Documents
The Tactic: Illinois divorce filings require precision. Missing a single form delays your case. It also signals disorganization to the court.
Why It Works:
- Complete filings move faster through the system
- Judges notice attorneys who file clean petitions
- Prevents opposing counsel from exploiting procedural errors
- Sets professional tone for entire case
Required Documents:
- ☐ Petition for Dissolution of Marriage (or Petition for Allocation of Parental Responsibilities if unmarried)
- ☐ Summons for service on your spouse
- ☐ Financial Affidavit (sworn and notarized). This document requires complete honesty. Omissions constitute perjury and destroy credibility.
- ☐ Filing fee payment: Cook County fees range from $337-$388 depending on case type. DuPage, Lake, and Will Counties vary. Confirm current fees before filing.
- ☐ Parenting Plan (if minor children involved). Even a proposed plan demonstrates proactive engagement.
- ☐ Certificate of Dissolution (required in some counties)
- ☐ Domestic Relations Cover Sheet
Strategy #3: Dominate the Discovery Phase
The Tactic: Serve comprehensive discovery requests within the first 30 days of your case. Respond to all requests completely and on time.
Why It Works:
- Forces opposing party to disclose evidence early
- Exposes weaknesses in their case
- Creates settlement leverage
- Prevents "ambush" at trial
Illinois Rules: Supreme Court Rules 213-214 govern interrogatories and document requests.
Implementation:
- ☐ Respond to interrogatories within 28 days (Illinois Supreme Court Rule 213). No extensions without court approval or opposing counsel agreement. One day late can result in deemed admissions against you.
- ☐ Produce requested documents completely: Use secure file transfer like Dropbox or ShareFile. Never use unencrypted email attachments. Organize documents by category with clear labeling.
- ☐ Prepare for deposition: Meet with your attorney at least 48 hours before. Review key documents. Practice answering difficult questions. A poorly prepared deposition created the record that sank Anh Nguyen's appeal in Kidder-Nguyen.
- ☐ Subpoena third-party records: Obtain bank records, employment files, medical records, and school records directly. Don't rely on your spouse to produce documents they control.
- ☐ Identify and prepare witnesses: Contact teachers, coaches, therapists, financial advisors, and neighbors. Coordinate schedules for potential testimony.
Strategy #4: Preserve Digital Evidence Immediately
The Tactic: Within 24 hours of deciding to file, preserve all digital communications and evidence. Implement cybersecurity safeguards.
Why It Works:
- Prevents spoliation (destruction of evidence)
- Captures metadata proving when messages were sent and read
- Preserves deleted content for forensic recovery
- Demonstrates credibility to court
Illinois Law: Spoliation can result in sanctions, adverse inference, or case dismissal.
Implementation:
- ☐ Enable two-factor authentication on every account. Use an authenticator app, not SMS verification. SIM swapping is a real threat.
- ☐ Monitor credit reports weekly: Identity theft and fraudulent accounts spike during divorce. Set up alerts with all three bureaus.
- ☐ Use VPN when accessing case documents from public Wi-Fi. This includes coffee shops, airports, and hotels.
- ☐ Never discuss case details on social media: Every post, comment, and like is discoverable. One client's Instagram story showing a luxury purchase undermined her financial hardship claims.
- ☐ Check for tracking devices: AirTags, GPS trackers, and phone spyware are common in contentious divorces. Have devices professionally swept if you suspect surveillance.
- ☐ Create new email account: Use this exclusively for attorney communications. Never access it from shared devices.
- ☐ Review shared cloud accounts: Check iCloud, Google Photos, and Dropbox. Your spouse may have access to everything you're storing.
Strategy #5: Build an Unassailable Custody Record
The Tactic: Create a comprehensive chronological timeline of all parenting events before filing. Document everything with timestamps.
Why It Works:
- Reveals patterns of behavior crucial in custody cases
- Identifies corroborating evidence and witnesses
- Exposes opposing party's inconsistencies
- Organizes your narrative for court presentation
Implementation:
- ☐ Create parenting time log: Document every exchange with date, time, location, and child's condition. Use a co-parenting app like OurFamilyWizard for court-admissible records.
- ☐ Gather school records: Collect report cards, attendance records, IEP documents, and teacher communications. Demonstrate your involvement in educational decisions.
- ☐ Compile medical records: Obtain pediatrician visits, dental records, therapy appointments, and prescription histories. Know your children's healthcare providers.
- ☐ Document extracurricular involvement: Track who signs up kids for activities. Note who attends games and performances. Record who communicates with coaches.
- ☐ Preserve evidence of other parent's conduct: Document missed parenting time, intoxication during custody, and inappropriate discipline. Timestamp everything.
- ☐ Identify potential witnesses: List teachers, daycare providers, coaches, and family members. They can testify to your parenting involvement.
Strategy #6: Weaponize Financial Disclosures
The Tactic: Use Illinois Supreme Court Rule 213(f) mandatory financial disclosures to catch the opposing party in lies.
Why It Works:
- Mandatory disclosures are sworn under oath with perjury consequences
- Non-disclosure or false disclosure triggers sanctions
- Creates impeachment evidence for trial
- Demonstrates pattern of dishonesty to court
Illinois Context: Illinois is an equitable distribution state. Courts divide marital property fairly, not necessarily equally. Your documentation determines what "fair" looks like.
Implementation:
- ☐ Compile complete income documentation: Gather W-2s, 1099s, K-1s, and pay stubs from the last 6 months minimum. Include bonus records, stock option grants, and deferred compensation statements.
- ☐ Document all bank accounts: List checking, savings, money market, and CDs. Include accounts in your name, spouse's name, and joint accounts. Don't forget online banks.
- ☐ List retirement accounts: Document 401(k)s, IRAs, pensions, and deferred compensation plans. Obtain current statements and plan documents. These often represent the largest marital assets.
- ☐ Inventory real estate: List primary residence, vacation properties, rental properties, and vacant land. Obtain mortgage statements, property tax bills, and recent appraisals.
- ☐ Document business interests: If either spouse owns a business,

Frequently Asked Questions
How do appellate decisions affect my divorce case?
Illinois appellate decisions interpret statutes and establish binding precedent for trial courts. A relevant appellate ruling can significantly impact your case strategy, available arguments, and likely outcomes. Your attorney should research recent decisions affecting your specific issues.
Can I appeal my divorce judgment in Illinois?
Yes, but appeals are limited to legal errors, not disagreement with factual findings. You must file a notice of appeal within 30 days of the final judgment. Appellate courts review whether the trial court applied the law correctly and whether findings are against the manifest weight of evidence.
What does 'unpublished' mean for Illinois appellate decisions?
Unpublished decisions (marked '-U') may not be cited as precedent under Illinois Supreme Court Rule 23. While they show how courts analyze issues, they don't establish binding legal rules. Published decisions create precedent that lower courts must follow.
