Selling a house with partial mortgage encumbrance: how to proceed when the property is divided
Published 31 October 2026
A house and land subject to a single mortgage can be sold separately, but only with the bank's explicit consent. The bank must release part of the pledge (lien), usually after you pay part of the debt, and only then can the buyer acquire just the part they are purchasing. The process is longer than a standard sale, so it is wise to start negotiating with the bank before you sign anything.
Summary
- The bank's pledge (lien) is registered against the mortgaged property; selling just part without the bank's consent is practically impossible.
- The bank decides whether to release part of the lien and assesses whether the remaining pledge sufficiently secures the outstanding debt.
- Partial sale typically requires payment of part of the loan, often directly from the purchase price held in a lawyer's escrow account.
- Ownership transfers only upon registration with the Czech Land Registry (Katastr nemovitostí), which takes approximately 3–4 weeks.
- If the land is divided, there is an additional step: geometric separation and registration with the Land Registry.
What it means when a mortgage encumbers both the house and the land
A bank secures a mortgage through a pledge (lien) on the immovable property. This is registered in the Czech Land Registry (Katastr nemovitostí) against the specific properties, most often for both the land and the house. As long as the pledge remains in place, the bank retains it even after sale, and the buyer takes it on along with the property. This is precisely why a buyer typically will not purchase without the bank's consent.
Under the Czech Civil Code No. 89/2012 (§ 506), a house is generally a separate thing, not part of the land. Therefore, it is possible to sell the house and land separately. However, the bank has typically pledged both in the mortgage, and its security is calculated on the basis of the whole. When you remove part of the whole, the value available to the bank changes.
The term "partial encumbrance" thus usually refers to a situation where you wish to sell only part of the mortgaged property—for instance, the land—and keep the rest. If you are selling everything and wish to repay the debt from the purchase price, that is a simpler procedure, which we describe on the page acquiring property with a mortgage.
How a divided sale differs from a standard sale
In a standard sale of the entire property, the debt is paid from the purchase price and the pledge is cancelled. The bank addresses one issue: how much it receives and when. In a divided property sale, the bank must additionally assess what remains for its security.
- Remaining security. The bank examines whether the remaining property is sufficient to secure the outstanding debt after part of the pledge is released.
- Amendment of agreements. Instead of a straightforward cancellation, the pledge agreement is typically amended: part of the property is removed, the rest remains pledged.
- Multiple entries in the Land Registry. In addition to the transfer of ownership, the change in the pledge is also registered.
- Possible division of the land. If you are selling only part of a parcel, it must first be separated to create an independent property.
What the bank actually assesses and approves
The bank is not obliged to grant consent. It decides according to its own rules, so find out in advance what it will require. These typically include the following areas:
- Value of the remaining security. The bank often verifies this through a valuation. Land without a house or a house without grounds may have a different value than you might expect.
- Payment amount. The bank may require a special loan payment. The bank determines the amount; it cannot be estimated in general terms. Often it is paid directly from the purchase price.
- Identity of the buyer and payment terms. The bank wants to know how and when the funds will arrive. Cashless payment through a lawyer's escrow account is clear and secure for it.
- Loan status. If the loan is being repaid on schedule, negotiations tend to be easier. In case of arrears or loan termination, there is less room for manoeuvre and it is best to act as soon as possible.
Always request consent in writing and verify the conditions under which it applies. An oral undertaking to sell is not sufficient.
How the sale proceeds step by step
- Land Registry extract and agreements. Determine which properties are pledged and obtain copies of your loan agreement and pledge agreement. The extract can be obtained via the Land Registry website or at the office.
- Consultation with the bank. Describe your intention to sell only part, inquire about the terms for release and ask for the outstanding loan balance.
- Division of the land, if necessary. A surveyor will prepare a geometric plan and the new parcel will be registered with the Czech Land Registry (Katastr nemovitostí) according to the Cadastral Act No. 256/2013. You should verify whether the division is in order under building law (access, utilities, setbacks) according to the Building Act No. 283/2021 and discuss it in advance with the relevant authority.
- Agreement with the buyer. The purchase agreement should include the bank's consent, payment of part of the debt and the cancellation of the pledge on the sold part as conditions.
- Lawyer's escrow account. The purchase price is placed in escrow. From it, the required amount is paid to the bank and the balance is paid to the seller.
- Application for registration. The transfer of ownership and change in the pledge are submitted to the Czech Land Registry.
Ownership transfers only upon registration with the Land Registry, and the registry office cannot decide before 20 days have elapsed since the owner was notified (Cadastral Act No. 256/2013). The average registration time is approximately 22 days.
What to watch out for
- Do not sell "on trust". Signing a purchase agreement before the bank grants consent may end with you failing to meet the obligation. Therefore, include the conditions directly in the agreement.
- Value of what remains. By selling the most valuable part—for example, a building plot—you may reduce the value of the remaining property. The bank will see this too and may demand a higher payment.
- Cash. Cash payment is limited to 270,000 CZK per day (Act No. 254/2004). Larger amounts are therefore paid cashless, preferably through a lawyer's escrow account.
- Co-owners and spouses. If the property is jointly owned or is part of joint marital property, you need the consent of the other persons. The general pre-emption right of co-owners has been abolished; it applies only for six months from the creation of joint ownership if the share arose by inheritance (§ 1124 of the Czech Civil Code No. 89/2012).
- Other encumbrances. In addition to the mortgage, the title register may contain other pledges, enforcement notes or easements (věcná břemena). Each of these needs to be dealt with separately.
Taxes and fees in brief
Transfer tax on immovable property has been abolished (Act No. 386/2020), so the buyer does not pay it. The seller may be subject to income tax on the sale under Act No. 586/1992, depending for example on the time test and whether the property is your residence. Discuss your specific situation with the Czech Tax Authority or a tax adviser. Agree in advance in the agreement who will pay the administrative fee for the registration application.
When you need a faster solution
A divided sale negotiated with the bank may take longer than you would prefer, especially if loan repayments are pressing or foreclosure is threatened. Sometimes it is simpler to sell the entire property and settle the debt from the purchase price. With a buyout offer you receive a quote within 24 hours, in writing and without obligation. Signing agreements and a deposit typically follow within 1–3 days, registration with the Czech Land Registry takes approximately 3–4 weeks, and the final payment arrives within 5 days of registration from the lawyer's escrow account. Legal service is provided at no charge, with no repairs or vacant possession required.
