Partner moving into a Czech rental: 2026 consent rules

Your partner is moving in, a child is born, a parent needs care, or a friend will share the apartment. The landlord asks for permission, a new fee or an addendum. Do not answer until you separate four different arrangements: visitor, household member, subtenant and co-tenant. They do not create the same consent, reporting, payment or exit rules.

The short answer for a partner or close person

Section 2272 of the Czech Civil Code lets a tenant receive another person into the household. A lease may reserve the landlord’s written consent for a new household member, but that reservation does not apply to a close person or a case deserving special consideration. Current MMR guidance identifies parents, children, siblings, spouses and partners as examples and also discusses unmarried cohabiting partners. The actual relationship still matters when the status is disputed.

Consent and notification are different. Even where the landlord’s consent is unnecessary, notify the increase in people living in the apartment without undue delay. Do not treat two months as a waiting period: the Code says failure to notify within two months is deemed a serious breach. Send a dated, provable notice promptly.

A visitor does not become a resident by the clock alone

The law does not create a universal “three nights” or “two-week” visitor cap. Look at reality: where the person normally sleeps, keeps belongings, receives post, contributes to the household, has another home and intends to live. A landlord cannot convert ordinary social visits into an automatic breach, but calling a permanent resident a visitor will not remove the reporting duty.

Use this consent and reporting decision

• Spouse or partner under the Civil Code: a close person, so the reserved consent does not apply; the relationship may also create joint tenancy by law, discussed below.
• Registered partner from before 2025: the older status continues unless the couple enters the newer Civil Code partnership. Do not assume that every rule for spouses applies; check the document and obtain advice on lease status.
• Long-term unmarried partner: MMR includes cohabiting partners among close-person examples; record the genuine household arrangement and notify it.
• Child, parent or sibling: ordinarily a close person; landlord consent is not required, but report the household increase promptly.
• Friend or new roommate: check whether the lease validly reserves written consent for a non-close household member before move-in.
• New child: no landlord permission is needed, but report the household increase so services and records can be updated.
• Carer or urgent family-support case: it may be a close-person or special-consideration case; document the reason and obtain advice if challenged.
• Person paying for independent use: test the arrangement against the separate household, sublease and consent rules.

A clause requiring consent for every close person does not override the statutory exception merely because it is signed. Conversely, do not assume every friend, date or informal arrangement is a close person. If the classification is uncertain, get individual Czech advice before creating an avoidable breach.

Send a notice, not a request for a right you already have

If a non-close person needs consent reserved by the lease, change the opening to a clear request for written consent and wait for an answer before move-in. Do not copy the one-month deemed-consent rule from some subletting situations into a household-member request; these are different legal routes.

If the person is your spouse or a partner under the Civil Code, do not add the sentence “this does not create a tenant.” Joint tenancy may already arise by law. State the marriage or partnership date and ask the landlord to update the lease record without making the update a condition of the statutory effect.

What information should the notice contain?

• Apartment address, tenant name and actual move-in date.
• Relationship or the reason consent is unnecessary, stated briefly and accurately.
• New total number of residents and information reasonably needed to calculate services.
• Whether the tenant continues to live there and whether any independent space is being granted.
• A request for receipt confirmation and a written calculation of changed advances.

Keep proof of delivery. If the landlord demands identity-card scans, sensitive identifiers, a new deposit or detailed private information, ask what legal or contractual purpose requires each item. The Civil Code household rule and Section 12 of the Services Act focus on reporting the changed number. Ask for the narrowest data set needed for any stated purpose. A reserved-consent request may need enough information to identify the proposed person, but a service-count update does not automatically justify an ID scan.

More residents may change services, not rent automatically

More people can change water, waste, lift, cleaning or other service allocation and justify a properly calculated advance adjustment. It does not by itself authorise an arbitrary “partner fee,” a second deposit or a rent increase. Ask which services use the number of people, the effective date and the new monthly calculation. Use the service-advance increase checklist and later reconcile the result against the annual service statement.

Under Section 2(g) of the Services Act, the relevant count generally includes the tenant and people expected to live with them for more than two months during the accounting period. Shorter periods can add up. Section 12 separately requires written notice of count changes without undue delay. The service-law definition is not a shortcut for deciding who is a household member, tenant or subtenant; keep status and allocation as separate questions.

Unmarried partner, Civil Code partner and spouse are not the same

An unmarried household member does not normally acquire an independent lease merely by moving in, paying half the costs or receiving post. If both unmarried partners should owe rent, receive notices and retain rights after a breakup, negotiate a written addendum with the landlord. Record its effective date, earlier debt, deposit ownership, notice rules and key return: co-tenancy creates exposure as well as protection.

Spouses are different. Under Sections 745–746, if the rented home is the spouses’ marital home, a lease held by one at the wedding can become joint on marriage; a later lease can become joint when it takes effect. The spouses can agree otherwise. Where joint tenancy exists, they are generally entitled and bound jointly and severally—an omitted name on the original lease is therefore not conclusive.

Since 1 January 2025, a same-sex partnerství under Section 655(2) of the Civil Code generally uses the rules for marriage and spouses unless legislation provides otherwise. That can bring the same Section 745 joint-tenancy analysis. A registrované partnerství concluded under the older Act by 31 December 2024 remains a distinct status until the couple enters the new partnership. Do not infer the result from the English word “partner”; check the Czech certificate, date, marital-home facts and any agreement excluding joint tenancy.

A permanent-residence registration is also separate and does not itself create lease rights. Use the permanent-residence guide for the registration evidence and later cancellation route.

There is no universal maximum headcount

Section 2272 allows the landlord to require a number appropriate to the size of the apartment and sanitary conditions, so everyone can live in usual comfortable and hygienic conditions. That is a fact-specific test, not a universal one-person- per-room formula. Floor area, room layout, facilities, age and actual use matter. Ask a landlord demanding a reduction to identify the specific capacity problem.

Report departures as well

Section 2273 requires the tenant to report a decrease in household members without undue delay. Give the actual move-out date, return access devices and request a service-advance update. If a co-tenant or subtenant is leaving, a mere household-count notice may not end their contract; use the shared-lease departure checklist.

Plan the breakup and death scenarios before moving in

If only one unmarried partner is the tenant, the other can be vulnerable after a breakup even after years of contributions. Record who owns furniture, who paid the deposit, how shared costs are settled, when keys are returned and what happens if one person wants to remain. A private agreement between partners does not by itself make the landlord accept a new tenant or release an existing one.

Death is a different legal route, not a continuation of the move-in rule. Succession can depend on household membership, whether the survivor has their own home and other statutory conditions; spouses or statutory co-tenants may start from a different position. Use the tenant-death and lease-succession checklist instead of relying on a household notice.

If the landlord refuses or threatens termination

• Preserve the lease, household notice, delivery proof, service calculations and every response.
• Ask whether the objection concerns consent, missing notification, subletting, occupancy or disturbance; each requires different facts.
• For a close person, cite the statutory consent exception while confirming the household count promptly.
• If you missed notification, cure it now and offer the information needed to correct service advances; do not backdate documents.
• If a formal notice arrives, switch to the termination validity and two-month review checklist immediately.
