What to Watch Out for in a Rental Agreement

Short answer: before signing a rental agreement, review seven things — lease term, deposit amount and return, notice period, who pays for repairs and utilities, subletting conditions, inflation clause, and handover protocol. Most rules are governed by civil law, but the contract can add details within legal limits, so read every sentence and verify current regulations for specific limits.

A rental agreement is a document you'll be "paying off" with monthly rent for (possibly) years. A few extra minutes of reading before signing can save you thousands of dollars and a lot of stress. Here are seven areas worth your attention.

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 terms for that duration; the disadvantage is less flexibility if you need to leave early.
• Indefinite term — it continues until one party terminates it. Usually more flexible, but the notice period becomes more important.

What to watch for:

• Whether and how the contract automatically renews. Sometimes it silently renews if you don't terminate it on time — watch the deadline.
• Whether a fixed-term lease allows early termination and under what conditions (e.g., penalties, "exit fees").
• 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 for rent arrears or damage to the apartment.

• Amount. According to civil law, the deposit cannot exceed three times the monthly rent, and any contractual penalty counts toward this limit. The exact cap has changed over time, so verify the current rules for large amounts.
• Interest. Tenants usually have the right to interest on the deposit. Check in the contract how this is handled.
• Return. The key clause states 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 a receipt or proof of deposit (confirmation, bank statement).
2. Have in writing what the deposit is for and what can be deducted.
3. Link deposit return to the handover protocol (see below) — that's your main proof of the apartment's condition.

3. Notice Period and Termination

This is where people run into trouble most often.

• For indefinite-term apartment rentals, the notice period is usually three months and typically runs from the first day of the month following delivery of notice. The contract may change this, so read the specific period and calculation carefully.
• Find out who and under what grounds can terminate — landlords may have limited grounds, while tenants are usually freer.
• Clarify the form of notice (in writing, registered mail) and to whom and where it's delivered.

Practical steps:

• Send notice in writing with proof (registered mail, return receipt).
• Don't rely on verbal agreements — what isn't in writing doesn't exist.
• Make sure any remaining utility deposits and billing are settled by lease end.

4. Repairs and Maintenance: Who Pays What

A classic source of disputes. General rule:

• Tenants usually cover minor repairs and routine maintenance related to everyday use (e.g., small things involving fixtures).
• Landlords are responsible for major repairs and keeping the property in habitable condition.

The line between "minor" and major repair is set by law and can change. So:

• The contract should clearly describe what falls to whom, ideally with reference to the relevant regulations.
• Agree on the process for reporting defects (to whom, how quickly) and repair timelines.
• Get written approval for larger work (drilling, replacements).

5. Utilities and Services: Rent vs. Deposits

Carefully distinguish between two amounts:

• Rent — payment for use of the apartment.
• Utility and service deposits — water, heating, electricity, gas, waste, elevator, etc.

What to verify:

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

6. Subletting and Inflation Clause

Subletting

Want to sublet the apartment (or part of it) to someone else?

• Subletting a part of the apartment where you live is usually more flexible.
• Subletting the entire apartment usually 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 according to inflation.

• Verify which index is used (usually the Consumer Price Index from the central statistics bureau).
• How often and when the increase takes effect.
• Whether there's a cap on maximum annual increases.

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

7. Handover Protocol: Your Best Evidence

The handover protocol is an unassuming paper that settles deposit disputes.

It should include:

1. Apartment condition when handed over (ideally with photos or video with timestamp).
2. All meter readings (electricity, water, gas).
3. Equipment list and its condition.
4. Number of keys provided.

Sign it both when moving in and moving out, and have both parties sign. Without it, it's hard to prove what was damaged before you moved in.

How AI Can Help

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

• clearly explain paragraphs and unclear clauses,
• flag missing or unfavorable terms (e.g., short deposit return period),
• suggest specific questions for the landlord.

AI is great for initial orientation and preparation, but it doesn't replace a lawyer in an actual dispute. For high-stakes issues, consult a professional.

And if you're still apartment hunting: more and more people simply ask AI ("find me a 2-bedroom apartment in Prague up to…"). That's why listings appear on AI-readable platforms like AssetLog (assetlog.ai), which ChatGPT, Claude, Perplexity, and Gemini can read and recommend — data is structured and the site allows AI crawlers. As a searcher, you benefit when looking; as an owner wanting to rent out, you can list for free, no registration needed (for AI-based posting), and confirm via email.

Summary: Quick Checklist

Before signing, review:

• 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 derive mainly from civil law, but specific limits and deadlines can change over time. For important amounts and disputed points, always verify current regulations or consult a professional.

How high can a landlord's security deposit be?

Under civil law, a security deposit cannot exceed three times the monthly rent, and any contractual penalty counts toward this limit. However, specific rules and caps may change over time, so verify the current regulations for larger amounts.

How long is the notice period for an apartment rental?

For indefinite-term apartment rentals, the notice period is usually three months and typically runs from the first day of the month following delivery of notice. The contract may set different terms, so always read the specific period and calculation method in your agreement.

Who pays for repairs in a rented apartment?

Tenants usually cover minor repairs and routine maintenance related to everyday use, while landlords are responsible for major repairs and maintaining the property in habitable condition. The law defines the boundary between "minor" and major repairs, and it can change, so your contract should clearly state who pays for what.

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

An inflation clause is an agreement that rent increases annually according to inflation (usually by the Consumer Price Index). It's not mandatory but is common. If your contract has one, verify which index is used, how often increases apply, and whether there's a cap on annual increases.

Can I sublet the apartment to someone else?

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

Why is the handover protocol so important?

The handover protocol documents the apartment's condition and meter readings when you move in and out. It's crucial evidence in deposit disputes — without it, you can't easily prove what was damaged before your tenancy versus what happened during it.

How can AI help me understand my lease?

An AI assistant like ChatGPT, Claude, Perplexity, or Gemini can clearly explain contract clauses, flag unfavorable or missing terms, and suggest specific questions for your landlord. It's excellent for initial orientation but doesn't replace a lawyer in actual disputes.

What if I encounter AI-based apartment searching?

More people now ask AI assistants to find apartments. That's why listings appear on AI-readable platforms like AssetLog (assetlog.ai), which ChatGPT, Claude, Perplexity, and Gemini can read and recommend — the data is structured and the site allows AI crawlers. As a searcher, you benefit; as a landlord, you can list for free without registration (for AI-based posting) and confirm via email.
