Accepting 15 boutique Australian firms for direct founder-led onboarding.
Generative AI has made convincing fabrication of SMS conversations, social media interactions, emails, images, and voice files instant and accessible to anyone. The legal system is actively adjusting, and solicitors are left carrying severe personal exposure.
Under uniform evidence rules (including the Evidence Act 1995 (Cth)), the burden of validating electronic evidence falls squarely on the party tendering it. The existing default alternative—expert forensic analysis—costs thousands of dollars per matter and takes weeks, rendering it completely disproportionate for routine litigation files.
Courts are already dealing with the fallout. The first guilty plea under Commonwealth deepfake provisions was recorded in April 2026. Explicit NSW Crimes Act 1900 amendments targeting synthetic material commenced on 16 February 2026. To tender digital evidence today without provenance safeguards is an active risk.
Under ASCR Rule 19, solicitors have an absolute personal duty not to mislead the court. Tendering unauthenticated screenshots that are later proven to be modified subjects your firm to critical negligence, costs disputes, and professional conduct inquiries.
By hashing and registering client-provided evidence at the moment of file intake, you freeze the timeline. Opposing counsel can no longer allege alterations were made during the proceedings. You demonstrate a clean, machine-attested custodian chain.

Court admissibility & Evidence Act Framing:
"This certificate authenticates that the cryptographic payload specified above was recorded on the public, immutable Polygon proof-of-stake ledger at the defined timestamp. This mechanism satisfies the requisites of machine-produced output reliability, and attracts the rebuttable statutory presumptions under s.146 and s.147 of the Evidence Act 1995 (Cth) and regional equivalents."
Public Blockchain Anchor
Under the Legal Profession Uniform Law cost regime, disbursements must be passed through to clients at cost. PRAViD's A$199 per-matter entry tier behaves exactly like an expert witness application or process-server expense—allowing your firm to use the tool completely free of overhead.
Paid by the client as a professional cost.
Absorbed as flat firm overhead.
For mid-tier multi-team practices.
Since Per-Matter charges are passed to clients as disbursements, your aggregate billing footprint drops once you move to a flat Professional subscription.
PRAViD does not claim that the core file content is objectively "true"—that is a fact-finding duty for the court. Instead, PRAViD proves a precise, narrow cryptographic primitive: that this file, exactly as presented, existed at this specific timestamp and has not been altered since.
Our certification process explicitly documents the reliability of the system generating the hash. This structured custody record empowers you to confidently argue the s.146 presumptions regarding machine-produced documents.
Because certificates are anchored to the public Polygon block-chain, anyone can verify the proof of a registered file without contacting, using, or paying PRAViD. Even if PRAViD went offline, your evidentiary record remains verifiable forever.
PRAViD never reads or holds the source files. No privileged files can ever be breached, subpoenaed, or leaked from our database.
All application workloads, databases, and metadata storage run locally in Australia-Southeast1 (Sydney region) infrastructure.
Every onboarded pilot receives a structured, plain-English legal package outlining how to brief judicial officers on the cryptography used in the certificates.
While digital litigation evidence is our beachhead, the horizontal PRAViD engine is already expanding. In 2026, we are rolling out vertical wedges for key sectors requiring absolute proof of time and custody.
Capture-time witness statements, testamentary capacity recordings, and digital asset ledger verification using identical client-side hashes.
