Costly mistakes to avoid
Check common pitfalls before you sign, pay or miss a deadline. Open each guide for the rules and practical steps.

Start with the situation that concerns you.
Housing and moving
Verify a rental before sending money
Check the advertiser and payment request independently before paying for a home you have not verified.
Find a homeCheck the deposit and its payment dates
Check the cash-deposit cap and instalment right before agreeing to pay the whole amount up front.
Tenant basicsCheck the annual service-charge bill
Check the charges and supporting records, and raise disputed items within the applicable objection period.
Tenant basicsGive valid lease notice in time
Check the notice form, all tenants’ signatures and receipt deadline so an ineffective or late notice does not prolong the rent obligation.

Contracts, purchases and money
Check the commitment before subscribing
Read the minimum term, renewal and cancellation rules rather than assuming a subscription can be ended every month from the start.
Contracts and subscriptionsDeclare withdrawal and return goods in time
For a purchase with a withdrawal right, check both the declaration and return deadlines instead of assuming one step completes both.
Consumer withdrawalAct on a court payment order
Check the court’s response deadline immediately if you dispute the claim; ignoring the order can lead to enforcement.
Debt collection and court payment ordersVerify urgent payment messages
Open the known bank or service yourself before following an unexpected login, payment or account-blocking message.
Scams and payment recoveryAsk for the full financial-product costs
Compare advice fees, product charges and exit costs before accepting a long financial commitment.

Work and unemployment
Check a dismissal deadline immediately
Get the court deadline checked as soon as written dismissal reaches you rather than waiting for negotiations to finish.
Employment contracts, dismissal and workers’ rightsGet advice before agreeing to leave a job
A resignation or termination agreement can affect unemployment benefit, so check the consequences before signing.
Unemployment benefitComplete unemployment registration
Do not confuse jobseeker registration with unemployment registration and the benefit application; check each required step.
Unemployment benefit
Official sources
Health cover and treatment
Clarify health cover when a job ends
Ask the fund what cover and contributions continue after a job or family cover ends instead of assuming the bills stop automatically.
Health insuranceAnswer the health fund’s income request
If you pay voluntary statutory contributions, missing requested income evidence can lead to a ceiling assessment; keep proof of what you submit.
Health insuranceHave planned dental replacement checked first
Before planned replacement teeth treatment, have the statutory fund check the treatment and cost plan and clarify your own share.
Dental care
Residence and visits
Apply for renewal before the permit expires
Use the authority’s accepted application route in time and keep proof rather than relying only on an appointment request.
Renew a residence permitUnderstand sponsorship before signing
A Verpflichtungserklärung can create liability for public living, health and care costs, so check what you are undertaking.
Invite relatives for a visit: visa and sponsorship
Family applications and departure
Report changes affecting child benefit
Tell the Familienkasse promptly about relevant household, education or departure changes rather than assuming another office updates the claim.
Child benefitApply for parental allowance promptly
Plan the application soon after birth because retroactive payment covers only a limited number of the child’s life-months.
Parental allowanceConfirm health-insurance end dates before leaving
Ask the insurer which cover and contributions end or continue; address deregistration alone does not settle every insurance obligation.
