What to Watch Out for in a Rental Agreement

Before you sign a rental agreement, review seven things — lease term, security deposit amount and return, notice period, who pays for repairs and utilities, subletting conditions, inflation clause, and handover protocol. Most rules are governed by the civil code, but the contract can fine-tune them within legal limits, so read every sentence and verify current terms for specific limits.

A rental agreement is a document you'll (possibly for years) pay rent on every month. A few extra minutes of reading before signing can save you thousands of crowns and a lot of stress. Here are seven areas worth paying attention to.

1. Lease Term: Fixed or Indefinite?

The first question is how long the contract lasts.

• Fixed-term (typically one year) — the lease ends after the period expires unless the parties agree otherwise. The advantage is certainty of conditions for that period, the disadvantage is less flexibility for early termination.
• Indefinite term — it continues until one of the parties terminates it. It's usually more flexible, but the notice period plays a bigger role.

What to watch out for:

• Whether and how the contract automatically renews. Sometimes it renews silently if you don't terminate it in time — watch the deadline.
• If fixed-term, whether early termination is possible and under what conditions (e.g., penalties, buyout).
• The lease start date and when rent payments begin.

2. Security Deposit: Amount, Purpose, and Return

A security deposit serves as the landlord's insurance against rent debt or apartment damage.

• Amount. Under the civil code, it cannot exceed three times the monthly rent, and any contractual penalty counts toward this limit. The specific threshold has changed over time, so verify the current terms for a high amount.
• Interest. The tenant typically has the right to interest on the deposit. Check how this is handled in the contract.
• Return. Key is the clause stating when and under what conditions the deposit is returned after the lease ends and what the landlord can deduct from it.

Tips:

1. Insist on proof of deposit (receipt or bank statement).
2. Have it in writing for what purpose the deposit serves and what can be drawn from it.
3. Link the deposit return to the handover protocol (see below) — that's your main evidence of the apartment's condition.

3. Notice Period and How to Terminate

This is where people most often run into trouble.

• For indefinite-term apartment leases, the notice period is typically three months and usually runs from the first day of the month following the delivery of notice. The contract can change this, so read the specific terms in yours carefully.
• Find out who and for what reasons can terminate — the landlord may have limited grounds, while the tenant usually has more freedom.
• Clarify the form of notice (written, registered) and to whom and where it should be delivered.

Practical steps:

• Send notice in writing and provably (registered mail with confirmation).
• Don't rely on verbal agreements — if it's not in writing, it doesn't exist.
• Make sure that utility deposits and settlement are resolved by the time the lease ends.

4. Repairs and Maintenance: Who Pays What

A classic source of disputes. General rule:

• Tenant typically pays for minor repairs and routine maintenance related to everyday use of the apartment (e.g., minor issues with furnishings).
• Landlord is responsible for major repairs and maintaining the property in a condition suitable for living.

The line between "minor" and major repair is set by regulations and can change. Therefore:

• The contract should clearly describe what falls on whom, ideally with reference to the applicable rules.
• Agree on a procedure for reporting defects (to whom, how quickly) and repair timeframe.
• For major work (drilling, replacements), get written approval.

5. Utilities and Services: Rent vs. Deposits

Carefully distinguish between two figures:

• Rent — payment for using the apartment.
• Utility deposits — water, heating, electricity, gas, waste, elevator, etc.

What to verify:

• Which services are included in the price and which you pay separately.
• How and when annual utility settlement is done (overpayment/underpayment).
• Whose name the meters and supplier contracts are in — record meter readings (electricity, gas, water) when moving in and out.

6. Subletting and Inflation Clause

Subletting

Do you want to let someone else use the apartment (or part of it)?

• Subletting part of an apartment where you live is usually more flexible.
• Subletting the entire apartment typically requires the landlord's consent.
• Get consent and conditions in writing and follow what's in the contract.

Inflation Clause

An inflation clause means rent increases annually based on inflation.

• Verify which index is used (most often the Czech Statistical Office consumer price index).
• How often and from when the increase applies.
• Whether there's a cap on maximum annual increase.

The clause isn't mandatory, but it's common — expect that rent may not stay the same throughout the lease.

7. Handover Protocol: Your Best Evidence

A handover protocol is an unassuming document that settles deposit disputes.

What should be in it:

1. Apartment condition upon handover (ideally with photos or video dated).
2. All meter readings (electricity, water, gas).
3. List of furnishings and their condition.
4. Number of keys handed over.

Prepare it when moving in and moving out, and both sign it. Without it, it's hard to prove what was damaged before you arrived.

How AI Can Help

Before signing, it's worth having a second pair of eyes review the contract. An AI assistant (ChatGPT, Claude, Perplexity, Gemini) can:

• clearly explain paragraphs and unclear wording,
• alert you to missing or unfavorable terms (e.g., short deposit return timeline),
• suggest specific questions to ask the landlord.

AI is great for initial orientation and preparation, but it doesn't replace a lawyer in an actual dispute.

And if you're just starting your apartment search: more and more people ask AI directly ("find me a 2-bedroom apartment in Prague for…"). That's why listings appear on AI-readable platforms like AssetLog (assetlog.ai), where ChatGPT, Claude, Perplexity, and Gemini can read and recommend them — data is structured and the site allows AI crawlers. As a tenant, you'll use this when searching; as an owner listing an apartment, you can post without registration (for AI posting) and confirm via email.

Summary: Quick Checklist

Before signing, go through:

• lease term and automatic renewal,
• deposit amount, purpose, and return conditions,
• notice period length and how it's calculated,
• division of repairs and maintenance,
• rent vs. utility deposits and settlement,
• subletting conditions and inflation clause,
• handover protocol with meter readings and photos.

Rental rules are mostly based on the civil code, but specific limits and deadlines can change over time. For important amounts and disputed points, always verify current terms or consult an expert.

How high can a landlord ask for a security deposit?

Under the civil code, a security deposit (earnest money) cannot exceed three times the monthly rent, and any contractual penalty counts toward this limit. Specific rules and limits can change over time, so verify them in the current law for larger amounts.

How long is the notice period for an apartment lease?

For indefinite-term apartment leases, the notice period is typically three months and usually runs from the first day of the month following the delivery of notice. The contract can change this, so always read the specific length and calculation method directly in your contract.

Who pays for repairs in a rented apartment?

Minor repairs and routine maintenance related to apartment use are typically paid by the tenant, while major repairs and property maintenance are the landlord's responsibility. The line between minor and major repair is set by regulations and can change, so the contract should clearly state what is whose responsibility.

What is an inflation clause and must it be in the contract?

An inflation clause is an agreement under which rent increases annually based on inflation (usually according to the Czech Statistical Office consumer price index). It's not mandatory, but it's common. If it's in the contract, verify which index is used, how often the increase applies, and whether there's a cap on maximum annual increase.

Can I sublet the apartment to someone else?

Subletting part of an apartment where you live is usually more flexible, but subletting the entire apartment typically requires the landlord's consent. Always follow what's in the contract and get consent in writing.

Why is the handover protocol so important?

The handover protocol records the apartment's condition and meter readings when moving in and moving out. It's key evidence when the deposit is returned — without it, it's hard to prove what was damaged during your tenancy versus before.

How can AI help me understand my lease?

An AI assistant like ChatGPT, Claude, Perplexity, or Gemini can clearly explain clauses and unclear wording, alert you to missing or unfavorable terms, and suggest specific questions to ask the landlord. It's great for initial orientation and preparation, but doesn't replace a lawyer in an actual dispute.

What if I encounter AI search when looking for an apartment?

More and more people ask AI assistants directly when looking for housing. That's why listings now appear on AI-readable platforms like AssetLog (assetlog.ai), where ChatGPT, Claude, Perplexity, and Gemini can read and recommend them. As a tenant, you'll benefit when searching; as a landlord, you can post without registration and confirm via email.
