Statutory route from abusive services to knowing facilitators

AB 621 / Civil Code 1708.86

California AB 621 became Chapter 673 of the 2025 statutes, amending Civil Code section 1708.86. Approved and filed on 13 October 2025 and effective 1 January 2026, it expands civil-law mechanisms concerning prohibited sexually explicit deepfakes and certain enabling services.

Liability and notice mechanics

Section 1708.86(b)(3) covers knowing facilitation or reckless aiding and abetting within the statutory scope. A depicted individual or public prosecutor can provide specified evidence and service information through the designated process. Failure to take necessary cessation steps within thirty days after receipt creates a presumption, subject to an investigation extension; notice itself is not adjudication. Prosecutors may seek injunctions and civil penalties of $25,000 per violation or $50,000 for malicious violations. Those are available remedies, not assessed amounts.

What the records show

AB 621 / Civil Code 1708.86Service-specific evidence → conditional presumption

establishes a receipt-based conditional presumption

Effective-date anchor, not receipt of any particular notice or expiration of the legal mechanism.

A depicted individual/public prosecutor must supply sufficient evidence of enabling an ongoing violating service, name it, generally describe enabling services and supply contact details; use prominently displayed designated process if present. Failure to take necessary cessation steps within 30 days after receipt supplies the presumption; a court may extend for investigation. No automatic adjudication or universal30-day immunity.

AB 621 / Civil Code 1708.86Public prosecutors under 1708.86

authorizes civil enforcement and court-awarded remedies

Effective-date anchor; actual judgment and quantum require their own record.

Public prosecutors may seek injunction/equitable relief, USD 25,000 per violation or USD 50,000 malicious violation, reasonable fees and other court relief without proof of actual harm to the depicted individual. These are remedy conditions, not assessed or received money. Private claimant damages are a different menu.
