Bacurin v. Bacurin

How did the court address the AI-related conduct?

In a signed order dated January 13, 2026, after taking the motion under submission at the January 12 hearing, Judge Sarah J. Heidel granted Luis's motion for summary judgment anyway. The court rejected the standing argument the defective citations were offered for, holding under Panterra GP, Inc. v. Superior Court that the right to reform an instrument is not restricted to the original parties to the transaction. It found a triable issue on mistake or fraud, and it rejected res judicata because the quiet title default judgment Luis relied on had been vacated on December 16, 2025. It granted judgment on judicial estoppel: the plaintiff had disclaimed any interest in the property in her 2010 Chapter 7 bankruptcy schedules, received a discharge, and offered no evidence that the omission was unintentional. The order imposes no sanction, issues no warning or admonishment, orders no explanation, and makes no referral concerning the citations; its only treatment of them is one sentence and a footnote in the standing discussion. A same-day minute order records the ruling and orders the defendant to prepare, serve and file a proposed judgment by February 2, 2026.

Why does Bacurin v. Bacurin matter for law firms using AI?

Bacurin is a family property dispute in which the party whose brief contained the defective citations won. The plaintiff claimed her siblings had promised she would remain an owner of a Grange Street property, and be added back to title, after she quitclaimed her interest in 2008; the defendant, now the sole owner of record, moved for summary judgment on several grounds. On the first, standing, Judge Heidel found that the motion’s authorities did not hold up: “Defendant references pin cites that do not support his contentions, quotes language which does not appear in the cited cases, and cites pages and cases which do not exist.”

Footnote 1 gives the court’s example. The motion attributed to “American Home Ins. Co. v. Travelers Indem. Co. (1985) 165 Cal.App.3d 138, 145” a sentence stating that a non-signatory, non-beneficiary lacks standing to seek reformation. The court found no 1985 case by that name and a 1981 case by that name that does not contain the quoted language. It then rejected the standing argument on the merits, relying on Panterra GP, Inc. v. Superior Court for the rule that the right to reformation is not limited to the original parties. The order does not mention artificial intelligence, and the Charlotin tracker’s AI coding is an inference the court did not make.

The motion was granted anyway, on judicial estoppel: the plaintiff had omitted any interest in the property from her 2010 bankruptcy schedules and obtained a discharge. The order imposes nothing for the citations and does not warn counsel. Firms documenting compliance may wish to consider that here the defective authority appeared in a moving party’s papers rather than an opposition, and that the court documented it in a signed order even though the motion succeeded on unrelated grounds.
