A formal notice clearly requests performance of an obligation.

## The legal starting point

A formal notice clearly requests performance of an obligation. It must fit the contract and applicable rules. Consumer debts owed to businesses have specific protections. A registered letter does not automatically establish the claim or interrupt limitation.



## Documents to gather

The contract, invoices, payment evidence and received letters with envelopes. Separate admitted and disputed amounts.



## Your next step

Write a short timeline and state the outcome you seek. Request a written explanation if an amount or decision seems wrong. Before signing, acknowledging a debt or allowing a deadline to pass, check the consequences for your circumstances. An amicable step does not automatically suspend a statutory deadline.



### Is a guide enough to decide?

It helps prepare your next step. Dates, documents and specific rules can change the answer. Consult the sources below and have decisive issues assessed.
