How a California medical malpractice case moves forward

A malpractice case usually begins with an investigation of records, deadlines, defendants, and causation. Filing a complaint is one stage of the process. It does not establish negligence, resolve expert disagreements, or create access to every hospital quality document.

1. Identify the claim and the correct parties

The initial assessment should distinguish the treatment event from the injury and from the date the patient first suspected wrongdoing. It should identify each potentially responsible clinician, professional corporation, medical group, hospital, employer, and other relevant entity. The name on a building or billing statement may differ from the entity that employed a clinician or operated the service.

Public entities, public employees, federal facilities, and federally deemed health centers can require different preliminary procedures. An arbitration agreement can change the forum. These issues should be investigated before assuming that an ordinary superior-court complaint and an ordinary malpractice limitations calculation are sufficient.

2. Preserve evidence and obtain a meaningful medical review

The investigation should assemble the clinical record, diagnostic materials, relevant communications, and a dated chronology. A printed chart may omit information needed to understand an electronic workflow. Where the facts justify it, preservation and discovery should address original electronic data, audit information, routing, acknowledgments, amendments, and relevant system configuration.

The medical review should test both breach and causation. An expert who criticizes care but cannot connect the criticism to compensable injury may not support a viable case. A defense review should address the actual criticism and the timeline rather than relying solely on the seriousness of the underlying disease or the absence of a Board citation.

California does not impose a general prefiling medical malpractice certificate-of-merit or expert-affidavit requirement comparable to those in some other states. Code of Civil Procedure section 411.35 concerns specified design professionals, not a general medical malpractice affidavit. Nevertheless, an action still needs a legally and factually supportable basis, and expert evidence is commonly necessary to survive a dispositive motion and prevail at trial. Absence of a mandatory filing certificate is not evidence that an expert is unnecessary.

3. Address notice, filing, service, and the response

Code of Civil Procedure section 364 generally requires written notice of intent to sue at least 90 days before commencing a professional negligence action against a health care provider. The notice and limitations rules require a coordinated calculation. Section 365 prevents treating noncompliance with this chapter as automatically invalidating proceedings or depriving the court of jurisdiction; it also preserves potential attorney discipline. This is a reason to understand the statute precisely, not a reason to disregard notice.

After filing and service, defendants can answer, challenge the legal sufficiency of the pleading, seek arbitration, or raise other procedural defenses. The court sets a case schedule. Allegations are then tested through document requests, interrogatories, admissions, subpoenas, depositions, and other permitted discovery.

4. Develop admissible evidence

Discovery should follow the issues: the clinical decisions, institutional responsibilities, causation, and damages. A preservation request and a demand for production are different tools. A party cannot assume that calling a document a “quality review” makes it privileged, or that placing a preexisting clinical record before a committee makes the underlying record disappear from discovery. Conversely, relevant information can still fall within a statutory protection. Privilege disputes require analysis of the particular material, its origin, and the governing law.

Physicians should give accurate testimony grounded in their knowledge and the record. If the record does not establish a fact and the witness does not remember it, speculation is not a substitute. A later explanation should be distinguished from a contemporaneous entry. Counsel should preserve both favorable and unfavorable evidence and address any necessary chart correction through the established transparent amendment process.

5. Exchange experts and address dispositive motions

California's expert disclosure procedure has its own demand, exchange, declaration, and deposition requirements. A strong clinical opinion can become unusable if disclosure or foundational requirements are not met.

A defendant may move for summary judgment by showing that an essential element cannot be established or that a complete defense applies. The plaintiff must respond with admissible evidence sufficient to create a triable issue, not simply repeat the complaint. Competing expert declarations should explain their reasoning and connect it to the relevant evidence.

Under the current version of Code of Civil Procedure section 437c, the ordinary minimum notice period for a summary judgment motion is 81 days before the hearing; opposition is ordinarily due 20 days before the hearing, and reply 11 days before the hearing. Service extensions, the trial date, court orders, and statutory exceptions affect scheduling. The statute also restricts new material in reply. Older descriptions using the former 75-day notice period should not be reused without checking the governing version.

6. Evaluate resolution and trial

Settlement evaluation includes liability, causation, economic loss, MICRA, liens, costs, collectability, insurance terms, and the uncertainty of trial. Code of Civil Procedure section 998 offers can create significant cost consequences when the ultimate result does not improve on a qualifying offer. Their drafting, timing, allocation, and good faith require care; an ordinary negotiating proposal is not automatically a statutory offer.

Mediation confidentiality is governed by its own statutory rules, including Evidence Code section 1119. It should not be confused with a blanket rule making all underlying facts or preexisting evidence confidential. Settlement confidentiality also does not cancel reporting duties imposed by law.

At trial or arbitration, the decision maker determines liability and damages under the applicable standards. Posttrial proceedings can address legal limits, judgment structure, fees or costs where authorized, and appellate issues. The conclusion of a civil case does not itself dictate the result of a licensing or credentialing proceeding.

Arbitration requires a separate analysis

Code of Civil Procedure section 1295 prescribes requirements for certain medical services arbitration agreements and provides a written rescission opportunity within 30 days after execution. Agreement formation, statutory compliance, scope, and the identity of persons allegedly bound remain important.

Ruiz v. Podolsky (2010) 50 Cal.4th 838 addresses circumstances in which a section 1295 agreement can bind wrongful-death heirs. Holland v. Silverscreen Healthcare, Inc. (2025), S285429, limits an overbroad application of that rule: a claim based on nonmedical custodial neglect does not bind nonsignatory heirs under that rationale merely because the defendant is a health care provider. The Supreme Court remanded for clarification of the pleading. The substance of the alleged misconduct and the agreement must be examined.
