Pre-action letter (předžalobní výzva)
A pre-action letter gives the other party a chance to fulfil their obligation before you go to court. In a tenancy, you will usually be demanding payment of a debt or that the tenant vacate the flat. The letter is not a court decision. How much notice you need to give and the other rules depend on what you are asking for.
Also known as: demand for payment before legal action, pre-action reminder, demand for performance
With a monetary debt, court costs are also at stake
§ 142a of the Code of Civil Procedure deals with costs in proceedings where you seek performance of an obligation. As a successful claimant, you are in principle entitled to have your costs reimbursed by the defendant only if you sent the letter at least seven days before filing the claim. It is sent to the defendant’s service address or, failing that, their last known address. The law allows an exception for reasons deserving special consideration.
So you can usually file a claim without a letter. But it will make a real difference to who bears the costs of the proceedings – which is a separate question from whether the debt actually exists.
What to include in the letter
Identify both parties, the lease, what you are demanding and why. For a debt, itemise the amounts and periods, the original due date, where to pay and the deadline for putting things right. Keep the principal separate from interest and other related charges. Keep a copy of the letter and proof that it was sent to the correct address.
To give you an idea: instead of “you owe us money”, state which monthly payment is missing and how you calculated the amount. The debtor can then either pay that specific debt or show why the figure is wrong.
A demand to vacate follows different rules
For an eviction order, § 175a requires a written demand at least 14 days before the claim is filed, and it must be attached to the claim. This is a different condition from the seven-day rule on costs. A notice to remedy before termination without a notice period under § 2291 of the Civil Code is also assessed separately. A single general letter may not serve all these purposes.
Before you send the letter together with Flat Service, reconcile the payment records and gather the documents relating to the lease. If the debt is disputed or the tenancy is ending, have a lawyer check both the content and the procedure.
