Organising family documents in Germany: what to keep, for how long, and where

In a family, only a handful of documents a year really count. Even so, the birth certificate is never to hand when you apply for a passport, and the service charge statement from three years ago is somewhere between the tax folder and a moving box. The real problem is rarely the quantity. It is that nobody decided in advance how long a document stays and where it lives while it does. This article answers both, sorted by the areas where families actually collect paper: personal documents, housing, vehicle, insurance and contracts, health, school, finances. Two topics get a paragraph of their own: ID copies, because they help on holiday and do harm in the wrong hands, and the emergency folder, which only proves its worth when things go wrong.

A note for readers who have moved to Germany, Austria or Switzerland: the rules below are German. Austria and Switzerland have similar ideas but different details and deadlines, so check the local rule if you live there. The German word for each document is given in brackets, because that is the word on the form.

Original, copy or digital: the basic rule first

Almost every document follows the same distinction. The original has to stay for certificates (birth, marriage, divorce), school-leaving certificates, notarised papers such as a house purchase contract, a will or a power of attorney, and savings books: anything where an authority or a court expressly asks for the original. A plain copy usually isn't enough there. You may digitise and then throw away whatever only serves as proof: invoices, bank statements, most contracts, user manuals. One exception: while a guarantee or warranty period is running, some retailers still ask for the original till receipt when you make a complaint, so you keep the paper copy until the period ends. If in doubt: a scan is enough if the document only proves that something happened. The original stays necessary if the document itself is the legal act.

Personal documents: what stays in the original for life

Birth certificate (Geburtsurkunde), marriage or civil partnership certificate, the Familienstammbuch (the family record book kept by many German families), a final divorce decree, acknowledgement of paternity together with the declaration of joint custody (Sorgeerklärung), naturalisation certificate, social security card: these papers stay in the original permanently, because they can't simply be reprinted anywhere. A new copy from the Standesamt (the local civil registry office) takes time, often costs money, and for older events isn't possible everywhere any more. ID cards and passports belong here too. You only need to keep expired ones if they contain visas you still need. Otherwise they can go as soon as the replacement has arrived.

What most often goes missing at the decisive moment in blended families: the custody declaration, when a parent without joint custody is asked to sign a form, and the child's birth certificate, when the child's own ID has to be renewed. Both are originals, and both are often in the other household. A copy in your own document folder saves the search.

Housing: tenancy agreement, service charges and what comes with ownership

For rented homes, keep the tenancy agreement (Mietvertrag) with all addenda, the handover record (Übergabeprotokoll) at move-in and move-out, with photos and not only text, and the service charge statements (Nebenkostenabrechnungen, the annual bill for heating, water, bin collection and so on, settled against your advance payments). For the statement itself there is a deadline of twelve months after the end of the billing period. If the landlord misses it, they generally can't claim anything more. For claims in both directions the usual limitation period of around three years applies after that; how it runs in a particular case is a question for advice. As a retention rule, it is enough to keep statements for at least three years after moving out, not only until the next moving box.

For home ownership, add the notarised purchase contract and the land register extract (Grundbuchauszug), both permanently and often kept by the notary anyway, property tax notices (Grundsteuerbescheide) and tradespeople's invoices for work on the house. A special rule applies to the latter: even private clients must keep invoices for construction and trade services on their own property for two years. This is a rule from VAT law meant to make undeclared work harder, and it is usually stated on the invoice itself. For your own protection, much longer is worth it: for work on a building, the warranty runs for several years, and without the invoice a claim is hard to prove.

Vehicle: two papers that should never be kept in the same place

The registration certificate part I (Zulassungsbescheinigung Teil I, commonly called the Fahrzeugschein) belongs in the car, as you must carry it for a check. The registration certificate part II (Zulassungsbescheinigung Teil II, the former Fahrzeugbrief) expressly does not belong in the glove box. Without it a vehicle can't be re-registered, so anyone who keeps both papers together in the car makes it easy for a thief to resell it. Part II is not proof of ownership; it only shows who is registered as entitled to dispose of the vehicle. Keep part II at home, in a place you will still find after years. That is exactly where it is missing most often: at the sale, when the buyer needs it to re-register.

Also keep the purchase contract or invoice, all garage invoices (a complete history is an argument when you sell), roadworthiness test reports (the TÜV or HU report, the German equivalent of the MOT), the eVB number from the insurer for a new registration (the electronic insurance confirmation) and the vehicle tax notice (Kfz-Steuerbescheid). Keep garage invoices for at least two years because of the warranty. As proof when selling, you need them for longer anyway.

Insurance and contracts: how long a policy stays important

While an insurance runs, keep the current policy to hand, not the version from three years ago that doesn't yet know about a changed excess. After a cancellation, hold on to the confirmation for a while. For most claims a regular limitation period of around three years applies, and for personal injury it can run much longer. As a rule of thumb: contract term plus at least three years afterwards, and longer for larger losses.

Many insurances run for a year and renew automatically if nobody cancels. A notice period of one month before the end of the insurance year is usual. For car policies running on the calendar year, that means in practice: if you want to switch on 31 December, send the cancellation by the end of November. The notice period in your contract is stated in the policy itself, so don't rely on the rule of thumb alone. That is exactly what makes autumn a sensible time to combine sorting your documents with a look at your running contracts (more on that at the end).

If a family separates, the contract topic gets harder in principle: who is liable for what, which special cancellation rights apply, what happens to joint policies. That is a topic of its own with its own deadlines, covered in detail in the article Sorting out contracts after separation.

Health: what stays for good and what can go after a few years

The vaccination record (Impfausweis), the maternity record (Mutterpass), the allergy passport and the severe disability card (Schwerbehindertenausweis) stay in the original permanently. They are needed with every new doctor, and a vaccination record can be reconstructed, but only with effort and seldom completely. The Mutterpass is often put away after the birth, although it is needed again in a further pregnancy, and doctors ask for it specifically.

Doctors' letters, test results and copies of prescriptions are needed less often in the original, but a few years makes sense. For chronic illnesses or earlier conditions relevant to later treatment, keep them permanently; in case of doubt the treating practice will help decide. Invoices for private supplementary insurance or Beihilfe (the state reimbursement of health costs for civil servants) are kept until reimbursement plus the usual three years or so.

School: what counts for the report folder

School reports (Zeugnisse) stay in the original permanently. A school-leaving certificate can be asked for decades later for a job application or a scholarship, and a duplicate, if there is one at all, takes effort. The same goes for completion certificates with value of their own, for example from a music school or a language exam. A running grade overview, on the other hand, is working material for the school year, not archive material. It can go after the report, as soon as the report itself is safely stored. How you organise the current school year without letters to parents and dates getting lost is covered in the article Organising everyday school life.

Finances: what the tax office wants to see and what you need for yourself

For private individuals without a business, there is, apart from special cases, no general duty to keep tax receipts. It is still worthwhile. The Finanzamt (the tax office) can reopen a tax case for some years, and without receipts a deduction can't be proved if in doubt. Four years from the relevant tax return is a defensible rule of thumb. For tradespeople's invoices on your own property, the two-year duty from the Housing section above applies in parallel.

Payslips are best kept by each person until their own pension notice (Rentenbescheid). The pension insurance asks specifically about gaps in the insurance record, and an old payslip is often the only proof of a year that would otherwise be missing. You don't legally need bank statements permanently, but three years makes sense, because most claims lapse after that long. Keep till receipts for more expensive purchases for at least the two-year legal warranty. For second-hand goods it can be agreed shorter, and with a longer manufacturer's guarantee you keep it correspondingly longer.

If you are self-employed or run a business, you are subject to separate, much stricter deadlines for business records. That is a topic of its own, where a word with a tax adviser (Steuerberater) is worth more than this article.

ID copies: useful on holiday, dangerous in the wrong hands

A copy of your ID card or passport pays off quickly on holiday. It is often enough when checking in at a hotel, and if the original is lost, it speeds up a replacement document at the consulate, because passport number and issue details don't have to be established first. For children without their own ID, a copy is often the only quick proof of who belongs to whom.

The very same copy is risky in the wrong hands. ID data is enough for identity theft, for contracts in someone else's name, for credit fraud. The usual mistake is not having a copy at all, but how it is kept: in the same wallet as the original, so both are gone in a theft, as an unencrypted photo in the general camera folder, or openly in cloud storage that several devices sync and nobody secures further.

Three habits lower the risk without costing the benefit. Keep copy and original apart, never in the same compartment. Store it digitally only in a password-protected or app-protected area, not in the open photo album or an unencrypted folder. And where it is enough, copy only the pages you actually need, not the whole ID as a precaution. patchio has a protected area for exactly this: in the document vault you store IDs and certificates as a photo or PDF, sorted by person. “Only me” is the default, a child's papers are visible only to their registered carers, and a household admin doesn't automatically see them. patchio asks for your password when you open them, and a reminder arrives before the expiry date – not an open folder that anyone with account access can browse.

The emergency folder: what goes in so nobody has to search

An emergency folder proves its worth on the one day when nobody has time to search. Sensibly filled, it contains:

• copies of the ID cards of all family members
• lasting power of attorney (Vorsorgevollmacht) and advance healthcare directive (Patientenverfügung), where they exist
• an overview of current insurances with policy number and contact details
• the most important bank details, but not the login details themselves
• the current medication plan of family members with chronic illness
• contacts: GP (Hausarzt), paediatrician (Kinderarzt), a trusted person outside the household
• a note of where the will or inheritance contract is held. The folder itself is the wrong place for that.

For blended families, one more item belongs here, which many only miss when it is too late: a written arrangement for who looks after the children in the event of a parent's serious illness or death, if that is not automatically the other biological parent. This is a legal question with its own instrument, the nomination of a guardian (Vormundschaftsbenennung). How you arrange it for your situation belongs in a consultation with a lawyer or notary, not in this article.

The folder only helps if a second person knows that it exists and where it is, if in doubt with a copy held by a trusted person outside your own household.

What can really go in the shredder at year-end

After the deadlines above, some things can go as soon as they have actually expired:

• bank statements older than three years, if there is no ongoing dispute
• till receipts and warranty cards whose statutory warranty and manufacturer's guarantee have both run out
• service charge statements more than three years after the relevant move-out
• policies of expired, uncontested contracts together with the cancellation confirmation, if more than three years have passed since cancellation
• tax records more than four years after the relevant return, as long as no assessment is still open
• old passports and ID cards without relevant visas
• advertising letters from insurers, brochures, expired loyalty card confirmations

When in doubt, one test question helps: is there still a deadline, a contract or a claim for which this paper is the evidence? No, then it can go. Yes, but unclear for how long, then rather wait another year than throw it away straight away.

The time to tidy up is autumn, not New Year's Eve

Two reasons make autumn a better time than the days between the holidays. For car policies with a calendar-year term, the chance to cancel ends at the end of November, so if you want to switch you have to know beforehand which contracts are running at all. And the tax year isn't finished yet, so a missing receipt can still be obtained if necessary.

In practice: once a year, ideally in autumn, go through your documents by the areas above, put what has expired in the shredder, add what is missing and check for the contracts straight away whether a cancellation at year-end is worthwhile. patchio already has a tool for this. In the Contracts area, the documents hang directly on the relevant contract, and the last day to cancel is calculated from the term and notice period, with a reminder in good time, instead of you hunting for the deadline on a calendar page.

A document system won't become perfect this way, and some paper will end up in the wrong place in the end. But the difference between a family that searches for ten minutes in an emergency and one that searches for two days almost always comes down to that one hour in autumn.
