Rental agreement guide: what landlords and tenants must know

Key clauses every rental agreement needs, how reservation agreements work, and whether you can sign a lease electronically.

Rental agreement: the complete guide for landlords and tenants

Whether you are renting out an apartment or taking on office space, a solid rental agreement protects both sides. Here is what every lease must cover, how reservation agreements work, and when an electronic signature is sufficient.

Legal framework across the EU

Residential tenancy law is not harmonised at EU level — each member state has its own rules. Some key differences:

• Slovakia: Residential leases are governed by §§ 685–716 of the Civil Code. Written form is mandatory. Security deposit is capped at 3 months’ rent for residential properties.
• Czech Republic: Rental agreements are governed by §§ 2235–2301 of the Civil Code (zákon č. 89/2012 Sb.). Written form is strongly recommended but not strictly mandatory for residential.
• Germany: Residential tenancy is governed by §§ 535–580a BGB. Rent increases are regulated; Mietpreisbremse (rent brake) applies in many cities.
• Austria: Governed by the Mietrechtsgesetz (MRG). Strong tenant protections, particularly for older buildings.

For commercial leases (offices, warehouses, retail), parties generally have more contractual freedom in all jurisdictions. The key is to have the terms clearly documented before occupancy begins.

Essential clauses in a rental agreement

1. Parties — full legal names and addresses of landlord and tenant.
2. Property description — exact address, size, condition at handover.
3. Rent and payment method — amount, due date, bank account.
4. Security deposit — amount, conditions for withholding, return timeline.
5. Lease term — fixed term or open-ended; notice period for each.
6. Permitted use — residential only, or can the tenant run a business from the property?
7. Utilities — who pays what (electricity, internet, property tax).
8. Maintenance — which repairs are the tenant’s responsibility versus the landlord’s.
9. Subletting — allowed, forbidden, or allowed with written consent?
10. Termination conditions — grounds for early termination by either party.

The handover protocol — your most important protection

A written handover protocol (also called a condition report) documents the state of the property at move-in and move-out. Without it, security deposit disputes become almost impossible to resolve fairly — there is no baseline to compare against.

The handover protocol should include:

• Meter readings (electricity, gas, water) at the date of handover.
• Description of fixtures, furniture and appliances with their condition.
• Number of keys handed over.
• Signatures of both parties with the date.
• Photographic documentation (ideally timestamped and attached to the protocol).

Reservation agreement: lock in the property before signing the lease

A reservation agreement is a short, binding document that:

• Reserves the property exclusively for the prospective tenant for an agreed period (typically 7–14 days).
• Requires the tenant to pay a reservation fee (often 1 month’s rent).
• States the conditions under which the fee is refunded (e.g., if the lease falls through due to the landlord).

Without a reservation agreement, there is nothing stopping a landlord from accepting a better offer while you are arranging finance or doing due diligence.

Fixed-term vs. open-ended lease — what to choose

Fixed-term lease: has a clear end date. If neither party renews, the relationship ends automatically. Advantage for landlord: easier exit without needing statutory grounds.

Open-ended lease: can be terminated by notice. Statutory notice periods vary by jurisdiction (typically 1–3 months). Tenants generally have stronger protection under open-ended leases.

Can a rental agreement be signed electronically?

For commercial leases (offices, warehouses, retail space): yes, fully electronic signing is valid under eIDAS across the EU.

For residential leases: electronic signing is valid in most EU jurisdictions as long as both parties consent. The key exception is real-estate transfer (buying/selling), which typically requires a notarised or certified signature — but a rental agreement does not fall into that category.

Common mistakes to avoid

• No handover protocol — without a written description of the property’s condition at move-in, security deposit disputes are almost impossible to resolve fairly.
• Vague termination clause — specify exactly how many days’ notice is required and what the valid grounds are.
• Missing deposit return timeline — set a specific number of days (e.g., 30 days after handover) to avoid endless back-and-forth.
• Unclear utility responsibility — disputes about who pays which utility bill are surprisingly common; specify every service.

How zipzipdoc helps

zipzipdoc generates a rental agreement or reservation agreement from your brief, handles the electronic signing process, and stores the complete audit trail — so both parties have proof of what was agreed and when.

Step-by-step: signing a rental agreement electronically

Here is the exact process for handling a rental agreement digitally from inquiry to signed lease.

Step 1: Draft the agreement

Generate the rental agreement in zipzipdoc by describing the property address, the parties, the monthly rent, deposit amount and key terms. The AI produces a complete draft including all statutory clauses for your jurisdiction — security deposit rules, notice period, utility responsibilities, maintenance division. Review and adjust before sending.

Step 2: Add the handover protocol as an appendix

Generate a handover protocol as a companion document. This records the property’s condition at move-in — meter readings, furniture inventory, description of fixtures. Attach it to the lease as a numbered appendix. The tenant signs both documents together in a single signing session.

Step 3: Send for electronic signing

Enter the tenant’s email and mobile number. The tenant receives a signing link, reviews both documents, and confirms their identity with an OTP code sent to their phone. No app installation is required on either side. Signing typically takes under three minutes.

Step 4: Archive and set renewal reminders

After signing, both parties receive a PDF copy with a full audit trail. zipzipdoc archives the documents in your dashboard. You can set automated reminders for lease renewal dates, rent indexation reviews, or deposit return deadlines.

Rent indexation: protecting the real value of rent

Without an indexation clause, the landlord bears the full inflation risk over a multi-year lease. A well-drafted indexation clause links annual rent adjustments to a published index — typically the Consumer Price Index (CPI) published by Eurostat or the national statistics office.

Key points for a valid indexation clause:

• Reference index: specify which index applies (e.g., Slovak CPI, German Verbraucherpreisindex, Eurostat HICP for cross-border leases).
• Review frequency: typically annual, on the anniversary of the lease start date.
• Cap and floor: consider setting a maximum increase per year (e.g., 5 %) to protect the tenant, and a minimum (e.g., 0 %) to ensure rent never decreases in deflationary periods.
• Notice requirement: specify how many days in advance the landlord must notify the tenant of an indexation-based increase (typically 30 days).

In high-inflation environments, the absence of an indexation clause significantly erodes the real value of a multi-year rental contract for the landlord.

Security deposit disputes: when withholding is justified and when it is not

Security deposit disputes are the most common source of landlord-tenant litigation. Here is a clear framework:

| Situation | Justified withholding? | |---|---| | Unpaid rent at termination | Yes | | Damage beyond normal wear and tear | Yes — documented with photos | | Cleaning costs if property returned in poor condition | Yes, if contractually agreed | | Normal wear and tear (minor wall marks, faded paint) | No | | Missing items not listed in handover protocol | No — insufficient documentation | | Improvements made by tenant without permission | Possibly, if restoration clause exists |

Without a signed handover protocol, the landlord cannot prove what “normal” condition was at move-in. Courts regularly rule in favour of tenants who dispute deposit deductions when no baseline documentation existed at the start of the tenancy.

Return the deposit within the timeframe stated in the contract (or the statutory default — typically 30 days after the end of the lease). Unexplained delay in returning the deposit can give rise to compensation claims in addition to the deposit amount itself.

Frequently asked questions

Does a rental agreement have to be in writing?

For residential leases in Slovakia, yes — written form is mandatory under § 686(1) of the Civil Code. In most other EU member states, written form is strongly recommended even where not strictly required, because verbal agreements are nearly impossible to enforce in disputes. An electronically signed agreement meets the written-form requirement.

How much can a landlord charge as a security deposit?

In Slovakia, the deposit is capped at 3 months’ rent for residential properties (no statutory cap for commercial). In Germany, the Mietkaution is capped at 3 months’ net cold rent. Rules vary by jurisdiction — always check the local law.

Can a landlord unilaterally increase the rent?

Only under conditions agreed in the lease or permitted by law. Without an indexation clause (e.g., linked to CPI inflation), the landlord needs the tenant’s consent. Unilateral increases without consent are not enforceable in most EU jurisdictions.

What happens if the tenant stops paying rent?

The landlord can terminate the lease on grounds of non-payment (typically after rent is overdue by 3+ months). The specific procedure depends on the jurisdiction. In Slovakia, a 3-month notice applies. Debt recovery proceeds through civil court proceedings.

Can a lease be signed electronically by both parties in different countries?

Yes. Under eIDAS, an AdES signed in Slovakia is valid in all 27 EU member states. Both parties can sign from different countries without any physical meeting — each receives a link and signs with OTP verification on their device.
