Power of attorney: the case almost nobody plans for

The gap almost nobody plans for

Most estate-planning conversations circle around death: who inherits what, how a digital account gets closed, where the will is kept. But a different scenario is statistically far more likely, and just as consequential: being alive, yet temporarily or permanently unable to manage your own affairs. A serious traffic accident, a stroke, a coma after surgery, progressive dementia — the trigger is almost always sudden and rarely announced.

At that moment, somebody needs to be able to act: transfer the rent, talk to the health insurer, sign a treatment agreement, manage a bank account, in the worst case help decide about surgery. The common assumption is: "my partner will just handle it" or "the kids will sort it out." Under German law, that assumption is wrong.

The widespread myth

There is no automatic legal representation right between spouses, or between parents and their adult children, in Germany. Unlike minor children, whom parents may represent by law, that automatic authority ends at legal adulthood. Without a power of attorney, a spouse cannot manage the other's bank account or speak with binding effect to doctors or authorities — the habit many countries have is not automatic under German law.

Since 1 January 2023, there is one important but narrow exception: the spousal emergency representation right under § 1358 BGB. It lets a spouse act on health matters — for example consenting to treatment — when the other is unable to decide due to unconsciousness or illness. This authority is legally capped at six months, applies exclusively to health matters, and does not cover banking, tenancy agreements, or other legal transactions. Beyond that, the gap remains.

Power of attorney, guardianship directive, general power: what's what

These terms are constantly confused, but they mean different things. Here is how they line up.

In practice, combining a power of attorney with an advance directive is the strongest setup: the power of attorney gives someone the authority to act, and the directive tells them which direction to take when a medical decision is in doubt.

When notarisation is required or advisable

Most powers of attorney only need written form: signed by hand, dated and placed. There are, however, areas where notarisation is legally required or effectively demanded:

• Real-estate transactions: if the attorney-in-fact is to sell, encumber, or amend a land-register entry, the land registry requires a notarised or at least certified power of attorney.
• Commercial-register entries: acting for a business registered in the Handelsregister likewise requires a certified form.
• Larger loans: banks often require a notarised signature on the power of attorney for loan agreements.
• Bank powers of attorney: even without a legal requirement, many banks insist on their own form or at least a certified signature before accepting an external power of attorney.

Practical advice: if you're considering notarisation for one section, it usually makes sense to have the whole document notarised. It costs more than a simple signature certification, but creates legal certainty across every area of life and avoids repeated queries from banks or authorities later on.

The power of attorney that survives death: the underrated bridge

Most powers of attorney don't automatically end at death — unless the document explicitly says otherwise, in which case it does lapse, and a critical gap opens. Heirs are legal successors, but without a certificate of inheritance they're often not yet able to act towards banks, landlords or insurers. That process can take weeks, in complicated cases months.

A power of attorney explicitly drafted to "survive death" remains valid during that period. The attorney-in-fact can keep paying rent, provisionally organise the estate, cancel contracts — without waiting for the certificate of inheritance. Formally they still act in the name of the deceased, but practically they take on exactly the tasks that would otherwise sit idle.

The Central Register of Powers of Attorney

A common misunderstanding: a power of attorney doesn't need to be "registered" anywhere to be valid. It is valid the moment it's signed. Still, registering it with the Central Register of Powers of Attorney (Zentrales Vorsorgeregister), run by the Bundesnotarkammer, is worthwhile. It records that a power of attorney exists and who holds it — not its content. If a guardianship proceeding starts, the court checks this register automatically. If it finds a matching entry, it notifies the attorney-in-fact instead of simply appointing an unrelated guardian.

Registration costs a one-off fee (currently in the low double digits of euros, scaled by the number of documents) and can be done online or by post. It does not replace keeping the original safe — the register stores no copy of the document, only a pointer to its existence.

Choosing the right person

The best-drafted power of attorney is worthless if it goes to the wrong person. What matters more than formal proximity (spouse, eldest child) is genuine trust and the ability to stay composed under pressure, acting in line with your actual wishes. Useful questions when choosing:

• Does this person really know my wishes, including the unspoken ones?
• Can they communicate factually with authorities, banks and doctors?
• Are they geographically and practically able to act in an emergency?
• Is there a conflict of interest, for example over a future inheritance dispute?

It's often wise to name a second, substitute person in case the first is unavailable — through illness, being abroad, or simply lacking time. If several people hold equal authority, the document should state clearly whether they can act individually or only jointly. Individual authority is more practical day to day; joint authority offers more control but can also cause deadlock in an emergency.

The practical core: findability beats perfection

The most carefully notarised power of attorney is useless if, in the decisive moment, nobody knows it exists or where it is. This is where most planning attempts actually fail in practice — not on content, but on findability.

A bank safe deposit box is a particularly poor choice: opening it often already requires a power of attorney or a certificate of inheritance — exactly the document sitting inside becomes unreachable. What works better is a combination: the original kept somewhere accessible at home (a fireproof document folder, for instance), a copy held by the attorney-in-fact themselves, registration with the Central Register for the court scenario — and at least one more trusted person who knows where the original is, even if they hold no authority themselves.

This is exactly where a digital legacy service like Erbnis is most useful. It does not replace any of the paper documents described here — a power of attorney remains a privately-signed or notarial original, not an entry in an app. What such a service can do is close the gap where things most often go wrong in practice: making sure the right person learns quickly, in an emergency, that a power of attorney exists, exactly where it is kept, and who else should be told. That combination — paper for legal effect, a reliable digital pointer for findability — covers the case that most planning efforts currently miss.
