*746*441S.A. appeals an order granting the petition of the Public Guardian of the County of San Luis Obispo (Public Guardian) for reappointment as the conservator of her person. A jury found beyond a reasonable doubt that she continues to be gravely disabled as a result of a mental disorder. ( Welf. & Inst. Code, 1 § 5000 et seq.; Lanterman-Petris-Short Act (LPS Act).)
S.A. contends her constitutional and statutory rights were violated when Public Guardian subpoenaed records of her care and treatment, signed an authorization for their release on her behalf, and then used the records against her at trial. We affirm.
FACTUAL AND PROCEDURAL HISTORY
S.A. suffers from schizoaffective disorder. She has not lived independently for more than 20 years. She has had many commitments to the County Psychiatric Health Facility (the PHF) and several LPS conservatorships.
In the summer of 2016, the trial court reappointed Public Guardian for a one-year period as S.A.'s conservator. We affirmed the order. (Conservatorship of S.A. (July 19, 2017, B276247) [nonpub. opn.].)
As that conservatorship period expired, Public Guardian petitioned to be reappointed again. S.A. contested the petition and requested a jury trial. The court set trial to commence in 25 days. (§ 5350, subd. (d).)
Two weeks before trial, Public Guardian served S.A. with copies of documents it intended to use as exhibits, including records of S.A.'s care and treatment at the PHF and at a board and care facility. S.A. moved in limine to preclude Public Guardian's experts from testifying to case-specific hearsay *442and opinions of other experts contained in those records pursuant to People v. Sanchez (2016)
When Public Guardian received S.A.'s motion, it served both facilities with subpoenas for production of authenticated copies of the records and gave S.A. notice of the subpoenas. Public Guardian signed authorizations for release of the records on S.A.'s behalf. The custodians of the records produced them along with affidavits attesting that the records were prepared in the ordinary course of business at or near the time of the events recorded.
S.A. amended her motion in limine to object to the use of the records at trial on the following grounds: she did not receive 10 days notice before their production ( Code Civ. Proc., § 1985.3, subd. (b)(2) ); Public Guardian had no authority to release them because it is not "the consumer ... or her attorney" (id ., subd. (c)(2) ); the records lacked foundation as business records because the affiants did not demonstrate knowledge of the method of their preparation ( Evid. Code, § 1271 ); the records are protected by S.A.'s physician-patient privilege (id ., § 994)
At the hearing on S.A.'s motion, the trial court said it would not allow experts to testify to case-specific hearsay not otherwise proved by admissible evidence, pursuant to Sanchez . It also accepted S.A.'s proposed redactions of conclusions, opinions, and remote or immaterial matters that she identified in the records. It otherwise overruled her objections, finding that the 10-day notice-to-consumer provision of Code of Civil Procedure section 1985.3 was not intended to apply to LPS proceedings; that Public Guardian was authorized by statute to sign the release of records and to waive S.A.'s privileges on her behalf; and that the records fall within the business records exception to the hearsay rule based on the custodians' affidavits and the court's review of the records.
At trial, psychiatrist Rose Drago read excerpts of the redacted records to the jury. She relied on them in part for her opinion that S.A. suffers from schizoaffective disorder, bipolar type, and is unable to provide for her own basic needs outside of a highly structured environment. Drago also relied on *443her 15 years of personal experience treating S.A., first as a staff psychiatrist and then as medical director for the County Mental Health Department until her retirement in 2011, and upon subsequent interviews with S.A., including an interview three days before trial.
Drago testified that she did not personally observe S.A. at the board and care facility, but reviewed records from S.A.'s five-day stay there. She described staff entries including the following: S.A. was threatening and aggressive and attempted to physically assault staff before she was transferred from the board and care facility to the PHF; said to a physician "I hate you because you're a woman and doctor. I don't need a psychiatrist. I'll decide if I want to hire you or fire you. I only work with Ph.D.s. Are you a Ph.D.? You could be a lunatic"; accused staff of keeping her property of "$100 million"; said that her spinal problems were the result of a fall caused by overmedication; said she was angry with her conservator and felt persecuted; refused a full injection of Haldol but agreed to a partial dose; said she healed a deaf man and made him speak; and said she had a $15 million Hyundai that was a submarine.
Drago also related details from the PHF records, including these: a staff member saw S.A. smoking, she had cigarettes and a lighter, and she said she was not a patient but was applying for a job; a staff member saw S.A. demand her cigarettes, wallet and phone so she could "call her ride"; she denied being under conservatorship and said she owned a home in Atascadero.
S.A. testified that she does not have a mental illness. She described her plans to work, find a place to live, and to feed herself if allowed to live independently. She testified she "always" takes her medication voluntarily except once when she was "crippled." She denied making certain statements attributed to her in the records.
In closing argument, counsel for Public Guardian referred to excerpts of the records and encouraged the jury to read them. The jury unanimously decided S.A. is gravely disabled, and the trial court *748renewed her conservatorship for a one-year period.
In a subsequent, bifurcated disabilities hearing, Public Guardian offered into evidence a record of a postverdict assessment by the County Behavioral Health Department. S.A.'s counsel objected to most of it on hearsay grounds, and "underline[d]" the part she "thought would be admissible under the business record[s exception]." The trial court sustained that objection and admitted only the underlined portion.
*444DISCUSSION
Public Guardian offered S.A.'s records to prove "the historical course of [her] mental disorder," a matter the jury was required to consider based on S.A.'s "medical records as presented to the court, including psychiatric records." (§ 5008.2, subd. (a); CACI 4011.) We conclude Public Guardian was authorized to do so, and that the manner of production and use of the records did not violate S.A.'s statutory or constitutional rights.
The Production of S.A.'s Consumer Records and the Conservator's Adverse Use of Them
In civil cases generally, a party who subpoenas a consumer's records must either demonstrate service to "the consumer ... or her attorney" at least 10 days before the date set for production, or furnish to the producing witness a written authorization for release signed by "the consumer ... or her attorney." ( Code Civ. Proc., § 1985.3, subds. (b) & (c).) Public Guardian gave S.A. a one-day notice before the date of production. It signed the authorization for release on her behalf. We agree with the trial court that the technical noncompliance with Code of Civil Procedure section 1985.3 's 10-day notice requirement did not render the production improper in this LPS proceeding and that Public Guardian was authorized to sign the release on S.A.'s behalf.
The rules of civil procedure generally apply to this special proceeding of a civil nature. ( Sorenson v. Superior Court (2013)
The accelerated procedure did not undermine Code of Civil Procedure section 1985.3 's purpose, which is to give the consumer notice and an opportunity to object to disclosure of private information. ( Foothill Federal Credit Union v. Superior Court (2007)
Code of Civil Procedure section 1985.3 does not expressly authorize Public Guardian to sign a release on S.A.'s behalf, but *749more specific statutes do. Medical providers are authorized to release a patient's records upon "written authorization ... signed by ... the ... conservator of ... her person or estate." ( Evid. Code, § 1158, subd. (b).) And a "conservator" is the "holder" of the psychotherapist-patient privilege and the physician-patient privilege "when the patient has a ... conservator." ( Evid. Code, §§ 993, 1013.) All information and records obtained in the course of providing services under the LPS Act are generally confidential (§ 5328), but they may be disclosed, (1) "in the course of conservatorship proceedings," when the patient or "her conservator" consents (id ., subd. (a)(1) ); (2) whenever the "conservator ... designates, in writing, persons to whom" they may be disclosed (id ., subd. (a)(4) ); or (3) "[t]o the courts, as necessary to the administration of justice" (id ., subd. (a)(6) ). Public Guardian was thus expressly authorized to release the records for use in the conservatorship proceedings, and it was authorized to use them to prove "the historical course of [S.A.'s] mental disorder." (§ 5008.2.)
S.A. contends the trial court violated her constitutional rights to privacy and due process when it allowed Public Guardian to use its position as her conservator to obtain and introduce evidence against her in adversarial proceedings. She points out that she has a right to privacy ( Cal. Const., art. I, § 1 ); she is not presumed to be incompetent as a result of her conservatorship ( Riese v. St. Mary's Hospital & Medical Center (1987)
S.A.'s rights to privacy and due process were fully protected. The trial was not open to the public and her records are sealed. (§ 5118; Sorenson , supra , 219 Cal.App.4th at p. 416,
*750S.A. points to cases that illustrate limitations on a conservator's powers, but none of them apply here. In Michelle K. v. Superior Court (2013)
S.A. cites a dependency case, In re M.L. (2012)
Hearsay
S.A. contends the records were inadmissible hearsay, and that Drago impermissibly relayed to the jury case-specific facts within them that were not otherwise proven. ( Evid. Code, § 1200 ; Sanchez , supra , 63 Cal.4th at p. 686,
The trial court has wide discretion to determine whether there is a sufficient foundation to qualify evidence as a business record; we will overturn its decision to admit such records only upon a clear showing of abuse. ( People v. Beeler (1995)
The trial court expressly found the records were trustworthy and supported by a sufficient foundation. The records from the board and care facility were accompanied by a declaration of a clinical administrative assistant who attests they were prepared or compiled by the facility's personnel in the ordinary course of business at or near the time of the acts, conditions, or events recorded, "to the best of [her] knowledge." The records from the PHF were accompanied by a substantially similar declaration from a medical records supervisor. The affidavits comply with Evidence Code section 1561, the *448purpose of which is to "ensure that such [nonparty business] records may ... be admissible without requiring their authenticity to be proved through live testimony from the custodian of records or other qualified witness." (Sen. Rules Com., Off. of Sen. Floor Analyses, 3d reading analysis of Assem. Bill No. 3001 (1995-1996 Reg. Sess.) May 16, 1996, p. 1; Cooley , supra , 140 Cal.App.4th at p. 1045,
S.A. contends the affiants do not establish their knowledge of the mode of preparation because they describe it only "to the best of [their] knowledge" and they do not provide sufficient information about the source of the information in each record. But it is not necessary that the witness called to present foundational facts have personal knowledge of every transaction; he need only be familiar with the procedures followed. ( Jazayeri v. Mao (2009)
S.A. argues that not every entry expressly states that the person who recorded it was the direct observer. She points, for example, to an entry that begins "Per staff ..." and questions whether the writer witnessed the events. But the trial court considered these arguments, reviewed the records, and found the PHF records were "clearly the reports of persons and staff, licensed psychiatric technicians, ... who are reporting [S.A.'s] observed conduct" and the board and care facility records were "obviously the observations ... of the people in the psychiatric program." The trial court accepted S.A.'s proposed redactions and found Public Guardian laid a sufficient foundation for their admission.
Drago's testimony about the contents of the records did not violate S.A.'s constitutional rights because she related only case-specific facts that were proved by admissible evidence. An expert witness may rely on hearsay in forming an opinion, and may tell the jury "in general terms" that she did so, but may not "relate as true case-specific facts asserted in hearsay statements, unless they are independently proven by competent evidence or are covered by a hearsay exception." ( Sanchez , supra , 63 Cal.4th at pp. 685-686,
*449DISPOSITION
The order is affirmed.
We concur:
GILBERT, P. J.
PERREN, J.
S.A. acknowledges that she did not raise the psychotherapist-patient privilege in the trial court and that "most of the material" in the records "would not fall under" that privilege.
