What Counts as Proof of Payment in a Child Support or Custody Case

When a co-parenting disagreement reaches a mediator, an attorney, or a courtroom, "I paid" is not enough. You need to show what you paid, when, to whom, and what it covered. The strength of your proof depends almost entirely on the kind of record you kept, long before the dispute started.

What weak proof looks like

These feel like evidence but are easy to challenge:

• A bare bank or card statement. It shows money left your account, not what it was for or that it was a shared child expense.
• A payment-app screenshot. A cropped image with a "thanks" note says nothing about which expense it covered, and a screenshot can be disputed as edited or out of context.
• Memory and text fragments. "I Venmo'd you in March" scattered across a chat thread is not a record anyone can rely on.

What stronger proof has in common

Credible proof of payment generally shows four things together:

1. The amount and date of the payment.
2. Who paid whom — both parties identified.
3. What it was for — the specific shared expense, not a generic transfer.
4. A record that has not been altered after the fact, ideally one both parents could see in real time.

The last point is what separates a convincing record from a contested one. A document that can be quietly edited later invites the question "how do we know this is what it said at the time?" A record that cannot be changed without detection answers it.

How to keep proof that holds up

You do not need anything exotic. You need to capture each payment against the expense it covers, keep the receipt, and store it somewhere both parents share and neither can rewrite.

That is the model behind SharedAnchor. You pay however you already pay — Venmo, cash, or check — since SharedAnchor never holds your money. The record is what is built for scrutiny:

• Each payment is logged against a specific shared expense, with the receipt attached.
• The record is shared and recipient-confirmed, so both parents saw the same history as it happened.
• Entries are append-only and tamper-evident: each is linked to the previous one with a SHA-256 hash and sealed in a daily checksum (a Merkle root), so an after-the-fact change breaks the chain. That verifiability is exactly what makes the export credible.

SharedAnchor organizes co-parenting payment records. It is not legal advice; what counts as admissible proof varies by court and situation, so consult a licensed family-law attorney.
