Smart home in custody battles. Why Alexa was the witness in seven divorce cases this year.

What actually gets subpoenaed

Smart home subpoenas are surprisingly broad. The categories that are most often requested, and most often produced, are not what most people expect.

Activity timestamps. Every time you say “Alexa, set a timer” or trigger any voice command, Amazon logs the timestamp, the device location, and the command. The same is true for Google Assistant and Siri Shortcuts. These logs are not recordings, they are metadata, but they still capture who issued a command, when, and from which device. In a custody case, a log that shows someone was home at 2 AM contradicts an account that says they were elsewhere. The metadata is the witness.

Voice recordings, when retained. Amazon’s default is to retain audio recordings of voice commands, though users can change the setting to retain text transcripts only or to retain nothing. Google’s default is similar. Apple’s default is not to retain audio at all, only on-device processing logs. The defaults matter. Most households have not changed them. Most households therefore have years of recordings that can be subpoenaed.

Smart lock and door-sensor logs. August, Schlage, Yale, and similar smart locks log every entry, exit, and code use. Ring doorbells log every motion event. Nest cameras log motion and audio events. These logs typically include time, duration, and which user or code was used. In a custody case, the lock log can prove or disprove a parent’s account of when they arrived to pick up a child.

Smart thermostat and energy data. Nest Thermostat and ecobee data showing when the home was occupied based on motion sensors. Smart meter data, where utilities cooperate with subpoenas, showing energy use patterns. None of this captures voice content, yet all of it ends up telling a clear story about who was home and when.

Music and video activity. Spotify, Apple Music, Netflix, and YouTube TV viewing histories tied to a smart speaker or smart TV in the home. Whose music played at a given time, which TV was on and when, and the activity itself is fingerprintable to a specific household member based on listening and viewing patterns.

Why this matters before a filing, not after

Once a divorce or custody filing is on the table, every action a party takes around digital data is scrutinized. Deleting smart home data after legal proceedings become reasonably foreseeable can constitute spoliation, which is treated more harshly than the underlying data would have been. The window where you can clean up your account in routine fashion closes before most people realize it has.

The honest version of the timeline is this. By the time you are seriously considering filing, the routine-hygiene window may already be closed. By the time you have decided to file, it definitely is. The actions described below assume you are still in the routine-hygiene window. If you are past it, talk to your lawyer before doing any of them.

If you have not yet made the decision to file but you are reading this article, you are likely closer to the filing than you think. The actions in this section are reasonable household privacy hygiene that anyone should take regardless of marital status. Frame them that way internally.

What to do, in order

1. Audit who has access to each smart home account

Most households have one Amazon, Google, or Apple account that owns the smart home, and that account is shared. The first step is to find out exactly who has logged-in access to the management dashboard. On Amazon, this is in the Alexa app under Settings, then Account Settings, then Amazon Household. On Google Home, it is in Home Settings, then Household. On Apple Home, it is in the Home app under Home Settings, People.

If your spouse has full administrative access and you anticipate proceedings, that access matters. Removing them from the household may be premature, but quietly mapping who has access right now is not. Document the current state: screenshots, dates. The screenshots become useful later regardless of what you do next.

2. Change the recording retention defaults

This single change carries the highest privacy benefit relative to its provocation risk for an opposing party. Changing your account’s setting from “keep voice recordings” to “do not save voice recordings” is presented by Amazon and Google as a privacy improvement. It is hard to characterize as suspicious behavior in retrospect.

On Amazon: Alexa app, Settings, Alexa Privacy, Manage Your Alexa Data, Choose how long to save recordings, set to Don’t save recordings. Then Manage Skill Permissions, audit. Then in the same area, manually delete the existing recording history. The deletion of past recordings is the more sensitive action. Deletion of routine personal voice data, before a filing, is generally defensible. Deletion of recordings made on dates that align suspiciously with claims you intend to make in the proceedings is not.

On Google: Activity Controls, Web and App Activity, set to off and delete the existing data. On Apple: this is mostly already done by default. Confirm in Settings, Siri and Search.

3. Document the state of every shared account before changing the password

If a divorce filing is imminent and you anticipate locking your spouse out of shared accounts, screenshot the state of each account first. Login history. Linked devices. Connected services. The screenshots become evidence of what existed before, in case data is later deleted by the other party or in case the timeline becomes relevant.

This is also the moment to create a list of every smart home device in the house. The list will be useful later for the lawyer, for the police if a domestic violence situation develops, or for you if you later wonder whether a device you forgot existed has been logging. We covered the broader audit framework in your spouse is probably reading your messages.

4. Decide on the timing of access changes with your lawyer

Locking your spouse out of shared smart home accounts is a tactical move with consequences. They will know within hours, and that knowledge can affect everything from the timing of the filing to the negotiation of temporary orders. Some lawyers prefer to see the lockout happen on the day of filing. Others prefer to leave shared access in place until temporary orders are entered. The choice depends on the local court culture and on the specific facts of your case.

This timing question belongs to your lawyer rather than to you. We covered the framework around device hardening in digital privacy checklist before filing for divorce, but the timing of the actions there has to integrate with the legal strategy.

What if recordings already exist that are damaging

This is the question that brings most people to this article. The honest answer has three parts.

First, if the recordings would be relevant to a proceeding that is already filed, they are now subject to litigation hold. Deleting them is spoliation. The penalty a court imposes for spoliation is often heavier than the impact the underlying recording would have had. The recording you wish did not exist will hurt less than the inference a judge will draw from your having destroyed evidence after the case began.

Second, if no proceeding has been filed but a reasonable person in your shoes would foresee one, you are in the gray zone. Lawyers will give different answers. The conservative answer is to talk to counsel before deleting. The aggressive answer is that routine privacy hygiene before a filing is defensible. The honest answer is that the line is not bright, and that the cost of getting it wrong is high enough that the conservative answer is usually correct.

Third, if no proceeding is currently foreseeable but you are uncomfortable with what is in the cloud, normal account hygiene before a filing is what most privacy advice would tell anyone to do, regardless of marital status.

Frequently asked questions

If my spouse owns the Amazon account, can they get my voice recordings?

Yes, they own the data tied to the account. The account holder controls the data, can listen to recordings, can read transcripts, and can subpoena the data themselves through their own account access without any court order. This is one reason why a marriage with a shared smart home account creates asymmetric exposure to the spouse who is not the account holder.

Does Apple HomePod data get subpoenaed the same way?

Less productively. Apple’s design choice to do most processing on-device means the data Apple itself holds is much smaller than what Amazon or Google retain. Subpoenas to Apple in family law cases generally produce less useful evidence than subpoenas to Amazon or Google. Apple is not exempt; the evidentiary value of an Apple subpoena is simply lower than the equivalent against Amazon or Google.

What about Ring footage if it has been deleted from the cloud?

Cloud deletion is reversible up to a point. Ring’s standard practice is to retain footage for the duration of your subscription plus a backup period of up to ninety days. A subpoena served within that window can recover footage that the user already deleted. After the retention window, recovery is generally impossible. That window is materially shorter than most users assume.

If I move out, should I take my smart speakers with me?

Talk to your lawyer first. The smart speakers are typically tied to whichever account is logged in. Physically moving the device does not change the account ownership. Whether resetting the device before moving is appropriate or premature depends on where the case stands. The right answer depends on the legal strategy and on whether the household property has been characterized yet for the proceedings.
