Identifies the four structural requirements for a plaintiff expert declaration that survives the defense attacks at California elder abuse MSJ: scoped qualifications, a Garibay-clean materials paragraph, reasoned opinion chains, and merit-based response to the defense expert.

What Your Expert Declaration Needs to Say to Survive California Elder Abuse MSJ

Defense's MSJ rests on a defense expert declaration. Your opposition rests on yours. The two meet in the same evidentiary universe — the medical record, the care plan, the charting — and the judge decides whether the competing opinions create a triable issue. Based on our review of California elder abuse summary judgment rulings, plaintiff expert declarations fail most often not because the expert is underqualified but because the declaration states conclusions where the law requires reasoning.

What defense attacks. Defense challenges plaintiff's expert declaration on four fronts: scope of competency under SARH, foundation under Garibay, reasoning under Powell and Bushling, and reliance on inadmissible materials such as CDPH inspection reports. A motion to strike is filed with the opposition deadline. Courts grant those motions when the declaration gives them reason to — a non-MD opining on physician diagnostic decisions, an opinion resting on unauthenticated co-defendant records, or five pages of conclusions with no reasoning.

What the law requires. Four cases set the foundational rules. San Antonio Regional Hospital v. Superior Court (2024) 102 Cal.App.5th 346, 352-353: a non-MD expert may opine if their competency bears specifically on the factual question — a wound care nurse can opine on turning protocols and skin integrity monitoring; the same nurse cannot opine on physician diagnostic decisions. Powell v. Kleinman (2007) 151 Cal.App.4th 112, 123: the declaration must set forth the matter relied on and explain the reasoning. Bushling v. Fremont Medical Center (2004) 117 Cal.App.4th 493, 510: expert declarations at MSJ require reasoned explanation, not naked assertions. Garibay v. Hemmat (2008) 161 Cal.App.4th 735: opinions resting on unauthenticated records from co-defendants or non-party facilities are vulnerable.

What the corpus shows. From our review of California elder abuse summary judgment rulings, the expert declaration that survives defense attack has three characteristics: it scopes the expert's competency specifically, it ties each opinion to a chain of reasoning from specific evidence, and it relies only on records within the evidentiary universe of the motion. In a 2026 Contra Costa County Superior Court MSJ ruling (No. MSC22-00100, 3/20/26), the recklessness opinion survived because it traced a specific chain: the chart reflected AFP test results as normal; those entries, on the expert's opinion, could not have reflected performed tests given contemporaneous wound status documentation; that pattern of false chart entries across an extended period was the basis for the conscious-disregard opinion. The conclusory version of that opinion — "the facility acted in conscious disregard of the decedent's needs" — would not have survived.

What plaintiff's counsel does. Four structural requirements.

Open with a scoped qualifications statement. The opening paragraph identifies the expert's license, specialty, years of experience in the specific domain, and the scope of the opinions that follow. "My opinions are limited to the nursing standard of care for wound assessment, turning protocols, and skin integrity monitoring in skilled nursing facility care of dependent elder residents." A scoped qualifications statement preempts the SARH competency attack before defense files it. An expert retained to cover every issue in the case — wound care, physician decisions, corporate structure — needs separate qualified opinions on each domain, not one declaration covering all.
Draft a materials-relied-on paragraph that resolves the Garibay issue. Every record the expert relies on for a load-bearing opinion should be either the moving defendant's own business records (authenticated through defense's own custodian-of-records declaration) or third-party records authenticated through plaintiff's own custodian-of-records declarations. If the expert reviewed CDPH inspection reports as background context, they stay in the background — the opinions rest on the medical record, not the CDPH findings. This is a drafting discipline, not a scope limitation.
Write each opinion as a reasoned chain. The Sababin audit is attached as an exhibit. The expert walks the court through it: what the audit methodology is, what the care plan required, what the charting shows on a date-by-date basis, what the omission percentage means, why the pattern reflects deliberate indifference rather than care-quality variance. The causation opinion traces the clinical mechanism from the specific failure through the documented progression to the specific harm — the Worsham-proof opinion. The court should be able to follow every chain from premise to conclusion reading the declaration alone, without the brief.
Respond to the defense expert on the merits, not on admissibility. The Rule 3.1354 objection paper carries the admissibility arguments against the defense expert. The plaintiff's expert declaration addresses the merits: where the defense expert addressed individual care episodes without engaging the pattern across the residency, where the defense expert's analysis didn't account for specific documented evidence, where the underlying reasoning is clinically incomplete. The expert explains the analytical gap. The brief argues the legal consequence.
