Full Text of § 425.50
Plain-English Summary
Section 425.50 sets detailed pleading requirements for construction-related accessibility claims — lawsuits alleging that a business or property fails to provide required access for people with disabilities. Subdivision (a) requires the complaint to identify the specific barrier in plain language, with enough locational detail for a reasonable person to identify it; describe how the barrier denied full and equal access or deterred the plaintiff on each occasion; and state the date of each occasion.
A further layer of disclosure applies specifically to complaints filed by or on behalf of a high-frequency litigant, as defined in § 425.55: except where the complaint alleges physical injury or property damage, it must disclose that the filer is a high-frequency litigant, how many similar complaints that litigant filed in the preceding 12 months, why the litigant was in the geographic area of the defendant's business, and why the litigant wanted to access it. Subdivision (b) requires verification of the complaint (subject to a motion to strike if unverified) and, for high-frequency litigants, a caption notice that the case is subject to a supplemental Government Code filing fee.
Subdivisions (c) and (d) impose a signature certification much like the one in federal practice: the attorney or unrepresented party signing the complaint certifies that it is not filed for an improper purpose, that its legal contentions are warranted, and that its factual allegations have evidentiary support or a reasonable prospect of gaining it — with sanctions available under § 128.7 for a violation, after notice and an opportunity to respond. Subdivision (e) preserves the ordinary right to amend under §§ 472 and 473, so long as the amended complaint still meets subdivision (a)'s pleading requirements, and subdivision (f) limits how the high-frequency litigant question can be litigated: the determination rests solely on the verified complaint and publicly available documents, with no discovery permitted on the question.
Frequently Asked Questions
What facts must a construction-related accessibility complaint include in California?
Section 425.50(a) requires a plain-language description of the specific access barrier with enough location detail to identify it, an explanation of how it denied access or deterred the plaintiff on each occasion, and the date of each occasion.
What extra disclosures apply if the plaintiff is a high-frequency litigant?
Section 425.50(a)(4) requires disclosure that the filer is a high-frequency litigant, the number of similar complaints filed in the prior 12 months, the reason the litigant was in the defendant's geographic area, and the reason the litigant wanted to access the business, unless the complaint alleges physical injury or property damage.
Does a construction-related accessibility complaint need to be verified?
Yes. Section 425.50(b)(1) requires the complaint to be verified by the plaintiff, and a complaint filed without verification is subject to a motion to strike.
Can the other side take discovery on whether a plaintiff is a high-frequency litigant?
No. Section 425.50(f) limits the high-frequency-litigant determination to the verified complaint and publicly available documents, and bars discovery on that question.
