German Employment Contract: What to Check Before You Sign

JobChamp Guide · Updated July 17, 2026

Before you sign a German employment contract (Arbeitsvertrag), look closely at the exclusion period (Ausschlussfrist), the overtime blanket clause (Überstundenklausel), the probation clause (Probezeit), and any non-compete (Wettbewerbsverbot). These clauses often shape your everyday work life more than the salary figure on page one, and many contracts arrive in German only.

The clause traffic light: what red, yellow, and green mean

Not every unusual clause is automatically a problem, but some wording deserves a closer look before you sign, especially if the contract is only in German. This overview helps you sort what you find quickly.

Exclusion periods: short windows, big consequences

Exclusion periods (Ausschlussfristen) set a window in which you must assert claims, such as salary, overtime pay, or vacation payout, in writing, or they lapse automatically. Three months is typical, sometimes staggered in two stages (first a written claim, then a lawsuit if needed). If the period is clearly shorter, it deserves a closer look.

These deadlines apply not only to claims that arise during the employment relationship, but also to claims after it ends, such as outstanding overtime or a payslip error. If you miss the deadline, you lose a claim you would otherwise have been entitled to. Note down which exclusion period applies to you right after you sign.

Overtime blanket clauses: usually invalid without a cap

Wording like "overtime is included in the salary" with no quantity limit at all is often considered non-transparent (intransparent) and therefore invalid. For what that means for your paycheck in practice, see our guide to overtime pay in Germany.

Probation, non-compete, and contractual penalties

By law, the probation clause (Probezeit) can run for a maximum of six months, so that the shortened two-week notice period applies during that time; our full guide to the probation period in Germany covers what else to check there. A post-contractual non-compete binds you even after your contract ends, but without a promised compensation payment (Karenzentschädigung) of at least half your last pay, it is generally invalid. Contractual penalties (Vertragsstrafe) must be proportionate in amount, or they can be challenged.

With training repayment clauses, what matters is how long the agreed tie-in period (Bindungsdauer) runs after the training and whether the repayment obligation tapers down over time. A clause demanding the full amount back regardless of whether you leave after one month or after two years is usually disproportionate and can be challenged. Also watch for revocation clauses (Widerrufsvorbehalt) on allowances or bonuses. They are not automatically unfair, but should clearly state under what conditions your employer may revoke them.

What must be in the contract: the Documentation Act in brief

The Documentation Act (Nachweisgesetz) requires employers to put the essential contract terms in writing. That includes, among other things, the contracting parties, start date, job description, salary, working hours, vacation entitlement, and notice periods. If something is missing, you are entitled to a written addition.

Details on probation, any shift systems, payday, and training entitlements now also count among the items your employer must document. Actively request missing information in writing instead of letting it slide silently. A complete, clearly worded contract ultimately protects both sides from misunderstandings.

Negotiating before you sign

The best time to raise unfair clauses is before you sign, not after. State specifically which points you want handled differently, and have any changes confirmed in writing. A serious employer usually responds calmly to factual questions about exclusion periods or overtime rules.

How to phrase your question

Instead of vaguely saying "that sounds off", ask something specific: "I noticed the exclusion period is one month; three months is more standard. Could we adjust that?" or "The overtime clause doesn't name a cap, could we set a specific number?" Precise, factual phrasing like this comes across as professional and meaningfully raises your odds of an actual change.

How to read the contract systematically

Instead of reading the contract once from start to finish and then signing, a two-pass approach helps. On the first read, go through the whole contract without getting stuck on individual clauses, just to get the overall picture. On the second pass, mark every clause that contains a deadline, a number, a cap, or an obligation specifically for you. That is exactly where most pitfalls hide, while general statements of intent rarely matter in practice.

Also important for the time after your contract ends: make sure the agreed notice period matches what's described in our guide to notice periods in Germany, and don't casually accept a deviation from the statutory baseline period if you're unsure.

Regional and industry differences

Not every clause is judged the same way in every industry. In sectors covered by a collective agreement (Tarifvertrag), many points, such as notice periods or shift premiums, are already fixed by that agreement and cannot be undercut to your disadvantage in your individual contract. So also check whether a collective agreement applies to your industry or employer, and whether your individual contract is even allowed to deviate from it. Especially at companies bound by a collective agreement, it's worth comparing your employment contract against the agreement before you flag a clause as a problem too quickly.

After you've signed: what you can still do

If you've already signed and only later realize a clause might be invalid, that is not automatically lost. Invalid clauses stay invalid regardless of whether you signed, because the invalidity follows from the content of the clause itself, not from your consent. You can still rely on this later, but you should get legal advice in a dispute, since the assessment of individual clauses often depends on the exact wording used.

The difference between verbal promises and the contract text

Interviews often come with verbal promises, about flexible hours, home office days, or an upcoming salary review. If none of that shows up in the written contract, it's often hard to prove later what was actually agreed in a dispute. Actively ask to have important verbal promises put in writing in the contract, or at least in a follow-up email, before you sign. That protects both sides from later misunderstandings and makes verbal promises legally tangible.

If you have little time to review

Some employers put candidates under time pressure by giving a very short deadline to sign. A serious company usually gives you a day or two of thinking time to read the contract in peace, and if needed have someone else look it over. If you're refused that time, or asked to sign the same day, that is not itself a validity problem for the clauses, but it is a warning sign for the tone you can expect once you're on the job.
