Czech sublease deposit not returned: recovery in 2026

You moved out, returned the keys and the “deposit” has not arrived. Before accepting “we have one month” or copying a lease-deposit calculator, identify what you signed, who received the money, what it secured and when repayment became due. Current Czech lower-court decisions support applying key apartment-deposit protections—including interest—to a residential sublease, but the exact Supreme Court answer has not yet been published.

Save the sublease, amendments, payment receipt, bank statement and every message about the deposit. Record the contractual end, actual move-out, key handover, meters and inventory. Download original-quality photos and video before a chat, cloud link or platform account disappears.

Step 1: prove whether you had a lease or sublease

• The owner contracted directly with you: this may be an apartment lease. Use the lease-deposit guide to Section 2254, the cap and interest.
• A tenant or cooperative member contracted with you: this is commonly a sublease, even if everyone informally called that person the landlord.
• An agency or platform took the payment: determine whether it accepted the deposit for a named party, held it in its own capacity, or charged a different fee.
• A hotel, dormitory or accommodation provider contracted with you: the arrangement may be accommodation rather than a residential sublease.

Map the parties with the rental-versus-sublease decision guide. The heading “kauce” on a transfer does not by itself prove which contract, obligation or debtor the payment belongs to.

Does a Czech subtenant receive interest on the deposit?

A May 2026 legal review identifies judgments from Prague, Brno, Náchod, Svitavy, Nymburk and Prague-West supporting sublease-deposit interest. A published 2024 Regional Court judgment also applied Section 2254(1)’s combined three-rent ceiling for security and contractual penalties to a residential sublease. These are meaningful authorities, but they are not a Supreme Court ruling on the exact Section 2254(2) interest question. State that level of authority if the claim is disputed.

Purpose matters. The cited interest line concerns a flat or house provided to meet housing needs, not automatically a business space, holiday stay, accommodation service or every payment called “kauce.” The Supreme Court has said that Section 2254 is expressly the special rule for apartment leases and that other lease security starts with general security law and the agreement. Sublease protection therefore rests on analogous application, not on replacing the word “tenant” in the statute.

Step 2: identify the person who owes the money

• Who is named as the tenant/sublessor in the signed agreement?
• To whose account or cash receipt did the payment go?
• Does the receipt say the agency collected for the tenant, or that it holds the money itself?
• Was the payment later transferred, credited against rent or replaced by another security arrangement?
• Did a new tenant, owner or property manager expressly assume the repayment obligation?

Send the first accounting request to everyone whose role is genuinely unclear, but do not assume the apartment owner owes a deposit paid to the tenant. A demand and later claim should identify the legally responsible person, not merely the most visible person connected with the apartment.

Step 3: reconstruct what the payment secured

Copy the exact clause and make a four-line ledger: deposit paid, obligations accepted as due, deductions disputed, and balance demanded. Keep rent, service advances, energy, contractual penalties, damage, cleaning, keys and prepaid rent on separate lines. A single rounded “final balance” hides which claims exist and which evidence is missing.

• Rent or use payments: list each month, due date, payment and any disputed end date.
• Services and energy: distinguish a final statement from an unsupported estimate of a future bill.
• Damage: identify the item, before-and-after condition, age, cause, repair method and defensible cost.
• Cleaning or repainting: compare the agreed return condition and actual evidence with ordinary use; do not accept an unexplained flat fee.
• Missing inventory or keys: compare both signed inventories and require the actual replacement basis.

Step 4: determine when repayment became due

Read the return clause together with the provisions on the sublease end, handover and final accounting. Record separate dates for contractual expiry or notice, actual vacation, key handover and any later service statement. If the contract states a clear return period, calculate it exactly and preserve proof that its triggering event occurred.

If no maturity is stated, do not invent a universal 30-day grace period. Section 2254 says return occurs at the end of an apartment lease; the current lower-court approach supports analogous protection for a housing sublease. Where the contract and applicable rule still leave the time open, Section 1958(2) allows the creditor to demand performance immediately and requires the debtor to perform without undue delay. Send a provable demand identifying the obligation, amount or calculation, account and payment deadline.

Deposit interest and default interest are two different claims

• Interest on the security: the current housing-sublease case line applies Section 2254(2), running from provision of the deposit. Its disputed “statutory rate” calculation needs contract-specific legal review; do not substitute the CNB default rate.
• Default interest: once a money repayment is due and unpaid, Sections 1968 and 1970 may add a separate claim. If no valid rate was agreed, Government Regulation 351/2013 generally uses the CNB two-week repo rate for the first day of the half-year in which default began plus eight percentage points.
• Start dates differ: deposit interest can run while the security is legitimately held; default interest starts only after the repayment debt is due and the debtor is late.
• Do not double-label: state the principal, each interest basis, rate, period and running total separately in a demand or claim.

Step 5: force every deduction into an evidence row

“The apartment was damaged” is not an accounting. Ask the holder to identify the contractual or legal basis, the event, amount, calculation and supporting document for each deduction. Compare it against your opening and closing evidence. A party asserting a claim cannot make it self-proving merely by subtracting it from money already held.

Section 2254 contemplates set-off of what the tenant owes from the lease. Under the general set-off rules, mutual claims must meet the legal conditions; Section 1987(2) excludes an uncertain or indeterminate claim from set-off. That does not mean an invoice is always mandatory or every disputed claim is automatically uncertain. It does mean “maybe there will be a service shortfall” or an unquantified damage allegation is not a safe substitute for an identified, calculable counterclaim.

Use the handover evidence checklist to organise rooms, meters, defects, inventory and keys. If the amount follows a disputed end of the sublease, keep the termination review as a separate branch: one dispute asks when the right of use ended; the other asks what balance is now payable.

Can the whole deposit be held until the service statement?

Not as a universal rule. Check whether the agreement validly ties a defined portion or the final balance to a later service reconciliation. Then identify the billing period, provider, advance payments, last known consumption, expected statement date and defensible reserve. Ask for the undisputed balance now. Holding the entire deposit indefinitely because some future amount might exist is materially different from reserving a calculated amount for a named pending item.

What if the contract says the deposit is forfeited?

A security is not automatically a contractual penalty. In decision 26 Cdo 1130/2022, concerning a land lease rather than a sublease, the Supreme Court rejected the idea that a return condition by itself made the entire security forfeitable when a defect existed at handover; later cure could restore the return duty. A housing sublease clause that converts every breach into loss of the whole deposit therefore needs separate review as security, penalty, damages and—where a professional supplies a consumer—an unfair term.

A first accounting and payment request

Attach useful copies, not your only originals. Send the request through a channel that preserves both its full content and delivery. If the holder admits part of the balance, ask for that undisputed part immediately instead of allowing one uncertain deduction to freeze everything.

If the first deadline passes

• Recheck the debtor’s current name, address, company number where applicable and evidence of delivery.
• Update the ledger with any admitted deduction, partial payment and the remaining principal.
• Send a properly addressed pre-action demand before suing; Section 142a of the Civil Procedure Code can affect recovery of legal costs and generally works with a demand sent at least seven days before filing.
• Do not wait for informal promises indefinitely. The general limitation period is normally three years, but its start depends on the claim and maturity; check it before filing.
• Check the claim, court jurisdiction, evidence, both interest calculations and cost risk before filing for payment or seeking a payment order.
• If the sublessor is acting as a business and you are a consumer, assess Czech Trade Inspection ADR; it is not a general route for a dispute between two private individuals.

The Czech Bar Association publishes the current route to legal assistance. Get individual advice early when the agreement is unclear, the holder denies receiving the money, there are competing claims, or a court document has arrived.

Eight myths that weaken a good claim

• Calling the contracting tenant “the owner” and demanding the wrong person.
• Saying Section 2254 can never protect a subtenant despite the current residential-sublease judgments.
• Presenting lower-court interest judgments as a final Supreme Court ruling.
• Treating deposit interest and default interest as the same rate and period.
• Assuming a one-month return window exists in every contract.
• Accepting “future services” as a reason to hold the entire balance without an amount or timetable.
• Treating ordinary wear, an unpriced allegation or a round cleaning fee as a proved set-off.
• Returning keys without a dated record, meter readings, inventory and photos.
