The Rule

California Corporations Code §1600 grants shareholders a right to inspect corporate books and records, but the scope of that right turns on share ownership. Any shareholder holding at least 5% of outstanding shares—or any shareholder who has been a holder of record for at least six months—has an absolute right to inspect and copy the corporation’s accounting books and records, the shareholder list, and the minutes of shareholders’ and directors’ meetings at the principal executive office during normal business hours. No statement of purpose is required. The right is unconditional.

Shareholders below the 5% threshold with less than six months of record ownership retain inspection rights under §1600(c), but must articulate a “proper purpose” reasonably related to their interests as a shareholder. Courts construe proper purpose broadly: investigating management misconduct, valuing shares, or coordinating with other shareholders on a pending vote all qualify. The corporation may defeat the demand only by demonstrating it is made in bad faith or primarily to harm the corporation’s business.

The shareholder list is a separate, powerful instrument. Under §1600(b), any eligible shareholder may demand a current list showing name, address, and number of shares for every holder of record. In contested situations—proxy fights, merger objections, minority buyout campaigns—that list is the indispensable starting point.

What This Means in Practice

Inspection demands arise most often in shareholder disputes, minority oppression claims, pre-litigation investigation of self-dealing, and derivative litigation. A minority shareholder who suspects a controlling shareholder or the board is engaging in interested transactions can demand board minutes and accounting records to build the factual record for a §800 derivative action or a squeeze-out challenge.

Timing matters on both sides. A corporation has five business days to respond to a written inspection demand. Unjustified refusal entitles the shareholder to a court order compelling compliance, and a court may award attorney’s fees against the corporation. For corporate counsel defending a demand, the window to assess eligibility, scope, and any privilege or trade-secret objection is short: five business days, starting from receipt of a properly formulated written demand.

Practitioner Takeaway

If you represent a minority shareholder with concerns about management conduct, send the §1600 written inspection demand before commencing litigation—the records obtained define the factual predicate for derivative claims, breach of fiduciary duty actions, and oppression-based buyout demands. If you represent the corporation, calendar the five-business-day response deadline the moment a demand arrives, evaluate whether the requestor qualifies, and determine whether any scope limitation, protective order, or privilege objection is warranted before producing a single page.
