How to remove a mortgage on a residential building when selling apartments
Published 6 November 2026
You cannot remove a mortgage unilaterally: the lien will only disappear once the secured debt is paid or after the bank agrees to release the lien and it is removed from the Czech Land Registry. When selling apartments individually, you must agree with the bank in advance on consent to your project and how proceeds from early sales will be used to repay the loan. Without this agreement, the bank will typically refuse to consent to the lien removal and the transfer of the apartment to the buyer will be blocked.
Summary
- The bank's lien remains on the building until the bank consents to its release; a mere decision to sell units does not extinguish the mortgage.
- Contact the bank before dividing the building and starting sales: you need its consent to the project and an agreement on how proceeds will repay the debt.
- Buyers want apartments free of liens, so payment is usually handled through attorney's escrow and lien removal is dealt with simultaneously with the transfer.
- The most common mistake is contacting the bank only after a reservation or purchase agreement with the buyer exists.
- Overlooking penalties, taxes and other charges can derail your financial model and the sales schedule.
A mortgage does not end automatically; bank agreement is essential
A lien on the residential building persists until the secured debt is paid or the bank releases the lien. Liens are governed by the Civil Code No. 89/2012 Coll. (from § 1309) and are registered in the Czech Land Registry (Katastr nemovitostí) under the Land Registration Act No. 256/2013 Coll.
When selling apartments individually, this means one thing: each apartment being sold must transfer to the buyer either free of any lien, or with explicit consent from both the bank and the buyer. Most buyers with their own mortgage will demand a clean title, as their bank will register a first-priority lien.
Moreover, the mortgage agreement typically contains restrictions on how you can deal with the mortgaged property, such as prohibitions on sale, letting or alterations without the bank's consent. Your specific terms are set out in your agreement, so review it first.
Step-by-step approach to negotiating with the bank
The correct order is: bank first, then owner's declaration of division, then sales. This way you avoid a situation where you have a buyer but the bank will not approve the transfer.
- Review your contract documents. Find out what your mortgage and lien agreement say about sale, division of the building, early repayment and penalties.
- Establish the current debt position. Request the outstanding balance from your bank and the terms for early repayment of the full loan or partial repayment.
- Prepare a project plan and financial model. The bank will want to know how many units will be created, at what prices you plan to sell them and over what time frame the debt will be repaid.
- Request written consent. Your request should cover consent to divide the building into units, consent to sell the units and consent to release the lien progressively.
- Agree on a release mechanism. Clarify what percentage of each unit's sale price will go to the bank and at what payment point the bank will issue consent to the lien removal.
- Only then begin marketing and sales. Reservation and purchase agreements should then reflect what the bank has approved.
Repayment from early sales and refinancing
The bank usually makes release of the lien conditional on a portion of each sale proceeding going towards loan repayment. The exact arrangement is a matter of individual agreement and cannot be promised in advance.
In practice, you will encounter two main models:
| Model | Key features | Points to watch |
|---|---|---|
| Progressive lien release | A portion of each unit's sale price repays an agreed portion of the debt; the bank releases its lien on that unit. | The bank may demand a higher percentage from early sales than corresponds to each unit's share. |
| Refinancing | The existing loan is repaid from a new source and the original lien is discharged or replaced. | The new lender sets its own terms; check fees and penalties for early repayment of the original loan. |
A typical value uplift from selling units individually rather than the whole building at once is 20–40 per cent; the exact figure depends on a feasibility study. These figures are important when negotiating with the bank, as they show where and when the debt will be repaid from. Since unit sales happen sequentially, the bank often wants to see a buffer for slower-than-expected sales.
What documents the bank typically requires
The bank decides based on documentation, so have your supporting materials ready before you request consent. The exact list varies between banks, but typically includes the following areas:
- current extract from the Czech Land Registry and a copy of the cadastral map,
- description of the project and proposed division into units, including a draft owner's declaration,
- valuation of the building and individual units,
- financial model: expected prices, sales schedule and repayment plan,
- summary of tenant agreements and occupancy status,
- building documentation and planning or consent records, if required under the Building Act No. 283/2021 Coll.,
- information about the owner, other liabilities and any further liens or restrictions on the building.
The project passes through three gates (legal, permit and sales), and you move to the next phase only with confirmed figures. The same logic applies when dealing with the bank: a documented plan, such as from an Audit and Plan, carries more weight than a general outline.
Lien removal from the land registry and buyer payment
A lien only disappears from the title once the bank issues a discharge document and an application is filed with the land registry office, so time must be factored in.
Ownership passes only when registered in the Czech Land Registry. The land registry office cannot decide before 20 days have passed from notifying the owner (Land Registration Act No. 256/2013 Coll.) and the average registration time is approximately 22 days. Check the specific timescale for lien discharge with your local land registry office.
The safe approach is to handle payment non-cash through attorney's escrow. The purchase price is released only once conditions are met: the bank receives the agreed amount, issues the lien discharge consent and the buyer becomes the registered owner. Cash payment is furthermore capped at CZK 270,000 per day (Act No. 254/2004 Coll.), making it impractical for apartment sales.
Common mistakes when discharging a mortgage
Most problems arise because the bank gets involved too late or terms are not put in writing.
- Contacting the bank only after signing with the buyer. If the bank refuses consent, you face a contractual dispute with the buyer.
- Oral agreement. Consent, the amount payable from each unit and discharge conditions must be in writing.
- Overlooked penalties and fees. Early repayment may carry financial consequences that should be built into your model.
- Other liens and restrictions. Apart from the mortgage, there may be enforcement liens or other charges on the property; these need to be dealt with too.
- Tax implications overlooked. Capital gains tax on sale proceeds is governed by the Income Tax Act No. 586/1992 Coll. (depending on factors such as the holding period and whether it was your principal residence). Get specific advice from a tax advisor or the Tax Authority.
- Overly optimistic sales plan. Your repayment plan must hold up even if sales are slower than projected.
What to do now
First, clarify your debt and lien position, then approach the bank. Gather your mortgage and lien agreement, current title document, overview of tenancy arrangements and the outstanding loan balance.
If you need figures for negotiating with the bank, an Audit and Plan will help—a paid feasibility study with results in around 6 weeks. If you want to manage the whole process, including bank negotiations and sales, under one agreement, see End-to-end realisation.
