Madigan & Lewis, LLP Offers Guidance for California Spouses Facing Discovery Disputes in Divorce

Family Law Firm Highlights Legal Tools Available When a Spouse Refuses to Cooperate With Financial Disclosure

SAN MATEO, Calif., Aug. 31, 2026 /PRNewswire/ -- Madigan & Lewis, LLP, a California family law firm, today addressed a growing challenge in divorce litigation: spouses who refuse to cooperate during the discovery process. While courtroom trials often draw the most attention, the firm notes that the most contentious battles in a divorce frequently occur earlier, when spouses are required to exchange financial records, business documents, and other information relevant to property division, support, and custody.

According to Madigan & Lewis, LLP, discovery disputes are especially common in high-conflict and financially complex cases, where hidden income, undisclosed accounts, complex business interests, and digital financial activity can turn routine information exchanges into prolonged legal battles.

"When one spouse refuses to be transparent, the discovery process can quickly escalate," the firm explained. "California family courts expect full financial transparency, and spouses have an ongoing duty to disclose assets, debts, income, and expenses under penalty of perjury."

Common Causes of Discovery Conflicts

The firm points to several factors that commonly fuel discovery disputes, including efforts to conceal assets, longstanding power imbalances over household finances, and deep distrust between separating spouses. Cryptocurrency and digital payment platforms have added new layers of complexity to these disputes in recent years.

Tools for Enforcing Compliance

Madigan & Lewis, LLP outlined the range of formal and informal discovery tools available to attorneys, including interrogatories, requests for production, requests for admission, and depositions. When spouses fail to provide complete information, attorneys may also issue third-party subpoenas to banks, employers, payroll services, and other entities that may hold relevant financial records.

The firm also emphasized the growing role of electronic discovery, which involves collecting and analyzing emails, text messages, cloud files, and social media records. In some cases, forensic experts are retained to recover deleted files or trace digital transactions.

When a spouse remains non-cooperative, whether through incomplete records, frivolous objections, or repeated delays, attorneys may file a motion to compel, asking the court to order compliance. Courts that grant such motions frequently consider monetary sanctions and, in more serious cases, additional evidentiary penalties against the non-compliant party.

Specialized Challenges in High-Net-Worth Divorces

The firm noted that financially complex and business owner divorces present unique discovery challenges, including business valuation, executive compensation packages, trust structures, and international assets. Forensic accountants are often retained in these cases to trace assets and identify discrepancies in financial records.

The Firm's Approach

Madigan & Lewis, LLP approaches discovery strategically from the outset of a case, conducting early case assessments to identify likely conflict points and information gaps. The firm leverages subpoenas, forensic tools, and expert resources to uncover hidden assets and verify disclosures, while pursuing negotiated resolutions when possible.

"A strong willingness to pursue enforcement remedies often encourages meaningful settlement discussions and greater cooperation," the firm said.

Individuals facing a divorce involving hidden assets, incomplete disclosures, or obstructive behavior are encouraged to contact Madigan & Lewis, LLP to discuss their legal options.
