"Can you send me a photo of the health card?" "Who has the vaccination booklet?" "Is the passport at yours or mine?" When there are two homes, the kids' documents become a weekly occasion for messages — and every message is a small friction, or a missed opportunity when the other doesn't answer in time.

The principle is simple: the kids' documents belong to the kids, and both parents must be able to hold them at the same moment, without going through the other.

What you always need to have

For each child, the minimum that should live in a shared place:

  • Identity: ID card, passport, tax code, health card
  • Health: vaccination booklet, test results, current prescriptions, allergies, the paediatrician's name and number
  • School: report cards, certificates, important notices, the school portal login
  • Activities: sports medical certificates, membership cards, enrolments
  • Legal: the separation agreement or court order, the part about the children

Why chat isn't enough

Sending each other photos of documents on WhatsApp is the most common solution and the worst: the photo gets lost among a thousand messages, isn't searchable, isn't updated when the document is renewed and — not a minor detail — your child's health card ends up in the chat backup, in the clear.

You need a place that's structured (by child, by category), updatable (one file, the latest) and encrypted.

An archive for the family, not for one parent

In KidBox, Documents belong to the family: folders and categories, and every file is visible to all members at the same instant. One parent uploads the report card, the other finds it. The file is encrypted with a key only family members hold: not even the people running the service can read it.

Two more tools make the difference for kids:

The Health section

Every child's visits, tests, vaccinations and treatments live in the Health section, with results attached. When the paediatrician asks "when was the last booster?", the answer is one tap away — for whichever parent is in the office that day. And the summary medical record is generated from the history, ready to show a new doctor or the emergency room.

The Wallet

Health card, ID card, activity membership cards: in the Wallet they're cards, ready to show, not photos buried in a gallery.

Setting it up in an afternoon

  1. One parent creates the structure: a folder per child, with Identity, Health, School, Activities inside.
  2. Upload what you have, each their own part. It doesn't need to be complete on day one.
  3. Agree on the update rule: whoever renews a document uploads the new one. Whoever receives a result attaches it to the visit.
  4. The photo replaces the original for almost everything: the original stays with whoever needs it, the copy lives in the app for both.

The passport case

The one document where a copy isn't enough. Agree on where the original lives and put the expiry in a shared section with a 6-month reminder: renewing a minor's passport needs both parents' consent, and finding that out a month before the holidays is a classic.

One last thing: passwords

School portal, canteen portal, the sports club's members area: kids have accounts, and the credentials usually live in one parent's head. In KidBox, passwords can belong to the family: both parents get into the portal without asking "what was the password?".

The real advantage

It isn't tidiness. It's that neither of you depends on the other any more for something concerning the kids. Fewer requests, less waiting, fewer chances to hold a delay against someone. When the documents belong to both, one piece of conflict simply has nothing left to feed on.
