Buying Czech property as an unmarried couple

You found an apartment together. One partner has most of the deposit, both incomes are needed for the mortgage, and the reservation deadline is tomorrow. “We will own it together” is not yet a plan. Before paying, decide the registered shares, the source of every large contribution, the loan responsibility, the exit mechanism and what happens if either partner dies.

Whose name should be on the apartment?

For registered real estate, Section 1105 of the Czech Civil Code makes cadastral registration the ownership-acquisition step. The title sheet identifies the owners or co-owners and their fractions. If only one partner is registered, the other does not acquire a cadastral share merely by living there, transferring monthly money or paying for a new kitchen.

Decide the intended ownership before drafting the purchase contract and vklad application. If both buy, specify each fraction consistently in the reservation, purchase, escrow, loan and cadastral documents. A one-half share is an ideal legal fraction in the whole property; it does not automatically mean one room, floor or parking space unless the relevant rights are separately defined.

Must the shares be 50/50?

No. A couple can acquire equal or unequal shares. The right answer is the one both understand and can defend after a bad outcome, not the one that avoids an awkward conversation today. Compare at least these inputs: cash deposit, family money, loan principal expected to be paid by each person, non-financial trade-offs and the reserve each retains after completion.

• Equal title, unequal deposit: record whether the difference is a gift, a repayable loan between partners, or an amount returned first from future sale proceeds.
• Unequal title, equal monthly payments: say whether the payments alter an internal claim, are occupation costs, or are deliberately ignored for settlement.
• Parents provide money: name the donor or lender, recipient, amount, repayment and whether anyone expects ownership or security.
• Only one partner owns: define whether the other person’s payments are rent, household contributions, a loan, or documented investment—not an undefined promise of “our apartment”.

Do not rely on a spreadsheet alone. Have a Czech lawyer coordinate the acquisition documents and a separate co-ownership or partner agreement so the internal economics do not contradict registered title, the mortgage or the bank’s security.

Ownership and mortgage liability are separate

A bank assesses the applicants and the specific property. It may require both incomes, particular owners to join the loan or security documents, and consent for later transfers. The exact responsibility of each borrower follows the signed loan contract; do not assume it equals the cadastral fraction. Where the contract makes co-borrowers responsible for the whole debt, a 30% owner can still face a claim exceeding 30% of the unpaid loan.

Your private agreement can allocate payments and reimbursement between you, but it does not reduce the bank’s contractual rights. Likewise, transferring a share after separation does not automatically remove a borrower or release the mortgage. A buyout must be coordinated with the lender through an approved assumption, release, refinancing or sale and repayment route.

Before reserving, get an income-based lending assessment and present the proposed shares, source of own funds and property. Use the Czech mortgage affordability guide to set a safe search ceiling, but treat only written lender documents as the answer for your transaction.

The agreement to make before reservation

• Acquisition: exact title shares, purchase price, deposit and transaction costs, plus evidence of every gift or private loan.
• Monthly operation: mortgage principal and interest, services, energy, insurance, property tax, maintenance and reserve contributions.
• Improvements: who can approve work, spending limits, ownership of invoices and how added value or cost is treated at exit.
• Use: occupation, home-office or rental rules, keys, guests, pets, parking and what happens during a temporary separation.
• Default: notice and cure period if one partner stops paying, emergency funding and the resulting internal claim.
• Exit: sale triggers, valuation method, first buyout opportunity, finance deadline, broker choice, minimum cooperation and controlled closing.
• Death: will and succession review, life insurance, debt repayment, temporary occupation and cooperation with heirs.
• Evidence: a shared ledger, bank records, invoices, annual reconciliation and written amendments.

A fair exit formula needs more than “each gets what they paid”. Define whether the calculation starts from gross value or net proceeds after mortgage, tax and sale costs; how it treats principal versus interest, improvements, exclusive occupation, unpaid costs and market loss; and who chooses the valuer if opinions differ.

If you break up: sale, buyout or co-ownership

The practical routes are a joint open-market sale, one partner buying the other out with lender approval, or temporary continued co-ownership under revised use and payment rules. Selling the whole apartment requires all title interests to transfer; a majority vote cannot sell a refusing owner’s share. Ordinary management generally follows a majority calculated by shares under Section 1128, while important matters generally require at least two thirds under Section 1129.

If agreement becomes impossible, Section 1140 states that no one can be forced to remain in co-ownership, subject to timing and abuse limits. Court settlement is therefore an ultimate exit, but not a promise of a fast sale or preferred price. The co-owned property exit guide compares a joint sale, buyout, share sale and judicial settlement.

If one partner dies: the survivor may not inherit the share

A cohabiting partner is not in the first statutory succession class. That class contains the deceased’s children and spouse or registered partner. A qualifying person from a common household can enter the second class only where descendants do not inherit, after at least one year in the common household and where the statutory care or dependency condition is met; that person cannot inherit alone in the second class. The person may also qualify in the third class and can be the sole heir there only if the other stated heirs do not inherit.

So “we have lived together for years” is not a safe estate plan, particularly where either partner has children. A Czech notary or succession lawyer should coordinate a will or inheritance contract, compulsory-heir rules, life insurance, the outstanding loan and a temporary right to occupy the home. The goal is not merely to name an heir: it is to prevent the survivor from co-owning the home with heirs while still facing an unaffordable mortgage.

What changes if you marry later?

Marriage does not by itself convert pre-marriage co-ownership shares into statutory community property. The government guide to the statutory matrimonial regime describes property acquired during marriage and its exceptions; pre-existing assets remain outside that automatic acquisition rule. If the couple wants a different structure, obtain notarial and lender advice and make the required contractual and cadastral changes rather than assuming the wedding changed the title.

Pre-reservation decision checklist

• Download the current title sheet and acquisition deeds; confirm the unit, land share, owners, burdens and pending seals.
• Write one page showing proposed ownership fractions, deposit sources, loan parties and post-completion reserve.
• Ask the lender in writing whether that structure is acceptable and what later buyout or release would require.
• Document family money as a gift or loan and identify its recipient before it reaches escrow.
• Obtain a coordinated Czech review of the reservation, purchase, escrow, mortgage and partner agreement.
• Complete the exit and death plan while both partners still expect the purchase to succeed.

The reservation agreement should identify both intended purchasers and make financing protection match the real structure—including an insufficient valuation or loan amount, not only outright rejection. The purchase-contract and escrow guide covers the payment and cadastral sequence after the structure is agreed.
