Cheapest Court-Approved Co-Parenting Apps UK (2026)

OurFamilyWizard charges each parent separately. Talking Parents does the same. For a separating UK family, that quickly adds up to £150–200 per year — for tools that are largely unchanged since they launched.

This guide compares the main apps with tamper-evident records available to UK families in 2026, ranked by cost. All prices are per family unless stated.

At a Glance: Price Comparison

App	Free tier	Paid (monthly)	Per parent?	Data location
Larkling	Yes — messaging, calendar, 1 Tone Coach/day	£6.99/mo	No — per family	EU (UK GDPR)
Talking Parents	Limited	~£8–9/mo	Yes	US servers
OurFamilyWizard	No	~£13–17/mo	Yes	US servers
2Houses	Limited	~£9/mo	Yes	EU servers

Larkling is the only app on this list that prices per family rather than per parent, and the only one with a genuinely useful free tier — not a time-limited trial.

What Makes a Record "Court-Ready" in the UK?

UK family courts don't certify apps. What they look for is evidence that records are authentic, consistent, and unaltered. The practical standard is:

• Timestamped — exact date and time of each message or entry
• Uneditable — no ability to change messages after sending
• Complete — a full continuous record, not cherry-picked screenshots
• Verifiable — ideally with cryptographic proof of integrity (SHA-256 hashing)

All four apps above meet the first three criteria. Larkling's Premium exports include SHA-256 cryptographic hashing — a digital fingerprint that proves the PDF hasn't been altered since it was generated. This is the same approach used in legal technology across many jurisdictions.

CAFCASS and Co-Parenting App Records

In UK family proceedings, the Children and Family Court Advisory and Support Service (CAFCASS) may review parental communications when preparing Section 7 welfare reports or risk assessments. CAFCASS officers are specifically trained to assess the quality and tone of co-parenting communication — not just what was said, but how.

This means consistent, timestamped records of calm, child-focused messaging can actively support your position, not just serve as defensive evidence. An app that also helps you communicate better — not just document that you communicated — is more useful in CAFCASS-involved proceedings than a simple message archive.

Larkling's Tone Coach checks messages before you send them and suggests calmer alternatives. One check per day on the free plan; 30 per day on Premium. It's not just a record-keeping tool — it actively helps you produce the kind of communication that holds up well to scrutiny.

If You're in Active Litigation or CAFCASS Is Involved

If you're currently in proceedings, tell your solicitor which app you're using and ask specifically:

• Whether the export format is suitable for what's needed in your case
• Whether the cryptographic hash should be mentioned when presenting documents
• Whether to start using a dedicated app now if you haven't already

Do not switch apps mid-proceedings without legal advice — continuity of record matters. If you're starting fresh, starting with a tamper-evident platform from day one avoids this problem entirely.

Talking Parents: The Established Choice

Talking Parents has a track record in UK and US courts. If your solicitor has specifically recommended it, that familiarity matters — particularly in high-conflict proceedings where a known name reduces challenges. The downside: it charges each parent separately, has no inclusive design for non-standard family structures, and stores data on US servers (which matters for UK GDPR).

OurFamilyWizard: The Premium Incumbent

OurFamilyWizard is the most expensive option and the most feature-rich. Its expense accounting features are more granular than any competitor. If your solicitor has recommended it specifically for complex financial dispute tracking, that's a reasonable case for the cost. For most families, the price is hard to justify.

Larkling: The Free Alternative

Larkling was built to make co-parenting tools accessible without charging per parent. The free tier covers messaging, shared calendar, and one Tone Coach check per day — enough for most families who just need to stay organised. Premium adds tamper-evident PDF exports (with SHA-256 hashing), unlimited message history, document vault, expense tracking, and 30 Tone Coach checks per day.

It's the only app built with LGBTQ+ families, non-binary parents, and non-standard family structures as the primary audience — not an afterthought. EU data storage keeps it clearly within UK GDPR requirements.

The honest caveat: Larkling is newer. It doesn't have the same court track record as Talking Parents or OurFamilyWizard yet. If your case specifically depends on a name that judges already recognise, that's worth considering.

The Bottom Line

For active, high-conflict court proceedings where your solicitor has named a specific app: use that app. Court familiarity is worth more than cost savings.

For everyone else — families wanting organised, documented communication without paying per parent — Larkling is the most cost-effective option with genuine tamper-evident records. The free tier is a real starting point, not a stripped demo.
