Verifiable expense records for court review
SharedAnchor helps co-parents produce tamper-evident expense records for court, mediation, and attorney review. Every submitted fact can be traced through an append-only ledger, a SHA-256 hash chain, and a daily Merkle root.
SharedAnchor organizes records for review. It does not provide legal advice or guarantee that a court will accept an export. Ask your attorney which records your case requires.
How the record can be verified
The goal is plain: an attorney, mediator, or court can inspect the export and confirm that a record still matches the ledger SharedAnchor stored.
Append-only ledger
Expense, payment, and custody records are added as new facts. Financial records are not edited in place or deleted after a dispute starts.
SHA-256 hash chain
Each row stores a fingerprint of its own contents plus the previous row. Changing an old record breaks every later fingerprint in the chain.
Daily Merkle root
Every day at 00:05 UTC, the day's record hashes are rolled into one root hash so a full day can be re-verified later.
A stronger trail than screenshots
Screenshots are easy to crop, reorder, or lose. SharedAnchor court exports are designed around verifiable data: the record hash proves what was stored, the previous hash proves where it sits in sequence, and the Merkle root proves the day was anchored as a batch.

The expense details describe the cost. The verification details help check whether the stored record has changed; they do not establish that the expense is owed.

Questions attorneys and co-parents ask
How does SharedAnchor support court review of expense logs?
Every record gets a SHA-256 hash, and each day's batch is anchored with a Merkle root inside the append-only ledger. That supports court review, but it isn't legal advice. Talk to your attorney about admissibility.
Can an attorney verify exported records?
Exports carry the record hash, the prior hash, and that day's Merkle root, so an attorney can check them straight against the ledger.
