California's New $435 Joint Divorce Filing Comes With Hidden Tax Traps

Los Angeles Divorce Attorney Hossein Berenji Reveals Why Low-Cost Filing Doesn't Guarantee Fair Property Division or Custody Protection

LOS ANGELES, CA, UNITED STATES, January 7, 2026 /EINPresswire.com/ -- Senate Bill 1427, effective January 1, 2026, expands California's joint petition divorce option to allow couples with children and significant assets to divorce for just $435. While headlines trumpet the bargain, Hossein Berenji, Divorce Attorney at Berenji & Associates, warns that couples may face unexpected costs if they skip proper legal review before filing jointly.

"The $435 filing fee is real, but one overlooked tax implication or undisclosed asset could cost a family tens of thousands in an inequitable property division," Berenji said. "The new law creates an entry fee advantage, not a cost advantage."

The law permits any couple to file a joint petition as long as they pre-agree on custody, support, and property division. Previously, summary dissolution was limited to marriages under five years with no children and assets under $57,000. The expanded option targets truly amicable couples seeking a streamlined process.

However, financial and legal experts caution that joint petitions hide several pitfalls. If either spouse later disputes terms, the case converts to traditional contested litigation, requiring full discovery that can cost $15,500 to $50,000 per spouse. Additionally, all preliminary disclosures have already been filed, placing the converted case at a disadvantage.

Capital gains taxes present a significant hidden liability. When a spouse receives appreciated property such as real estate or investment portfolios, the long-term capital gains tax owed upon future sale—especially if the spouse is no longer eligible for the primary residence exclusion—can substantially reduce the asset's net value.

"What we see repeatedly is couples filing jointly without understanding tax structuring, business valuations, or custody modification procedures," Berenji explained. "Once the joint petition is filed, the opportunity for correction shrinks significantly."

Child custody arrangements, though locked in by joint petition, often require modification within three years due to employment changes, school transitions, or evolving child needs. Requesting modifications requires proving "material change in circumstances," a higher legal standard than the initial agreement.

Berenji emphasized that SB 1427 serves a purpose for truly cooperative couples with simple finances. "For younger couples with minimal assets, shorter marriages, and no children or a stable co-parenting relationship, the joint petition works well," he said. "The moment a couple has appreciable property, retirement accounts, business interests, or any pre-existing disagreement, expert legal review before filing is essential, not optional."

Couples should budget for a pre-filing consultation before submitting a joint petition. This upfront investment protects against later potential discovery costs that can reach into the tens of thousands per spouse if disputes arise.

Berenji recommends that couples considering a joint petition hire a Certified Divorce Financial Analyst, conduct business valuations if applicable, document all separate property with clear evidence, model out custody modifications, review tax returns and retirement statements for QDRO requirements, and consult a family law attorney to ensure enforceability and long-term protection.

"Divorce is never cost-free. The question is whether you pay upfront for expert review and proper structuring, or later through remedial litigation, tax bills, and regret," Berenji concluded.
