The vocabulary, because the act's terms are not intuitive. In California's enactment the custodian is the platform, defined as "a person who carries, maintains, processes, receives, or stores a digital asset of a user"; the user is the person with the account; and the fiduciary is "an original, additional, or successor personal representative, conservator, agent, or trustee". Two further terms do most of the work. An online tool is "an electronic service provided by a custodian that allows the user, in an agreement distinct from the terms-of-service agreement between the custodian and user, to provide directions for disclosure or nondisclosure of digital assets to a third person" — in practice, the legacy-contact or inactive-account setting inside the platform itself. A designated recipient is "a person chosen by a user using an online tool to administer digital assets of the user", which is a role that exists only because online tools do.
The order of authority, and the condition on it that is easy to miss. Section 873(a) provides that a user may use an online tool to direct the custodian to disclose or not disclose some or all of their digital assets, including the content of electronic communications, and that "if the online tool allows the user to modify or delete a direction at all times, a direction regarding disclosure using an online tool overrides a contrary direction by the user in a will, trust, power of attorney, or other record." The conditional clause matters: the online tool wins because it is revocable at any time, so a tool that locks a choice in does not get that priority. Where no online tool was used, or none is offered, section 873(b) lets the user allow or prohibit disclosure in a will, trust, power of attorney or other record. And section 873(c) provides that either direction "overrides a contrary provision in a terms-of-service agreement", which is what stops the platform's own contract settling the question.
The two opposite defaults are the heart of the act. For the contents of electronic communications, section 876 requires disclosure only "if a deceased user consented to or a court directs disclosure", and the personal representative must give the custodian a written request, a certified copy of the death certificate, a certified copy of the letters of appointment, "a small-estate affidavit under Section 13101, or court order", and — "unless the user provided direction using an online tool" — a copy of the will, trust, power of attorney or other record evidencing the user's consent. For the catalogue of electronic communications and for everything other than content, section 877 runs the other way: "unless the user prohibited disclosure of digital assets or the court directs otherwise, a custodian shall disclose", on the same documentary showing minus the consent record.
So silence produces a split result. It loses the contents of the messages and keeps the catalogue, which section 871(c) defines as "information that identifies each person with which a user has had an electronic communication, the time and date of the communication, and the electronic address of the person." The practical instruction follows directly: use the platform's online tool wherever one exists, because it outranks the will, and where no tool exists, the will, trust or power of attorney has to say expressly that the contents of electronic communications may be disclosed. A document that is silent has chosen the default.
The platform keeps the upper hand on how it complies. Section 875 provides that a custodian may, "in its sole discretion", grant full access, grant partial access sufficient for the fiduciary's task, or simply "provide the fiduciary or designated recipient with a copy in a record" of the digital assets. It "may assess a reasonable administrative charge", "need not disclose … a digital asset deleted by a user", and where a partial request would require segregation that "would impose an undue burden" it may decline, with either side able to petition the court, including for disclosure to the court for review in camera.
What a fiduciary does not get. Section 874(b) provides that the act "does not give a fiduciary or designated recipient any new or expanded rights other than those held by the user"; 874(a) preserves the custodian's and the user's rights under the terms-of-service agreement; and 874(c) provides that access "may be modified or eliminated by a user, by federal law, or by a terms-of-service agreement when the user has not provided any direction" recognized by section 873. Federal law is doing real work in that sentence: section 876's court-order route contemplates a finding that disclosure "would not violate" the federal stored-communications provisions at 18 U.S.C. 2701 and following, and section 222 of title 47. Which is why writing the passwords on a card is not a plan. It may breach the platform's terms, it does not confer authority on anyone, and it goes stale at the first password change.
A scope limit worth one clause, and a recency point that is California's alone. The act does not apply to "a digital asset of an employer used by an employee in the ordinary course of the employer's business" (section 872(b)). And California extended its version to conservators appointed, and to fiduciaries acting under powers of attorney executed, "before, on, or after January 1, 2025" — an amendment specific to California, which should not be generalized to any other state's version.
