Why a written contract is essential
The Civil Code recognizes verbal leases, but in practice a verbal agreement leaves you without evidence on exactly what matters most: agreed rent amount, term, start date, security deposit delivered, authorized improvements, termination conditions. When a dispute arises, without a written contract everything is left to the judge's discretion based on witness statements and conjecture.
A written rental agreement protects you on at least five fronts:
- It precisely defines what is being leased: location, area, conditions at handover.
- It sets the price and the rent-increase regime.
- It secures the term and the conditions for renewal or termination.
- It regulates the security deposit: amount, retention and refund.
- It resolves in advance what happens with improvements, repairs and damages.
Applicable legal framework
- Civil Code (Decree-Law 106), Articles 1880 to 1941 — general lease regime.
- Tenancy Law (Decree 1468) — special regime for urban residential leases.
- Commercial Code (Decree 2-70) — for commercial leases (premises with a commercial business activity).
- Civil and Commercial Procedural Code, eviction proceedings (desahucio).
Critical clauses that cannot be missing
1. Identification of the parties and the property
Complete information of the landlord and tenant (DPI ID, NIT tax ID, address). Precise description of the property: address, area, included facilities, condition at handover.
2. Term and renewal
Defined term (typically 1 year for residential, 3–5 years for commercial). Renewal regime: automatic, by prior agreement, with an option for another term. Exact start and end dates.
3. Rent and increase regime
Amount, payment date, place and method of payment. If rent increases are agreed (fixed annual, indexed to inflation), they must be expressly stated. Without an increase clause, the landlord cannot raise rent unilaterally.
4. Security deposit
Amount (typically 1–3 months of rent), form (cash, bond, insurance policy), conditions for retention and refund. Without a clear clause, disputes over the security deposit are the most frequent at the end of the contract.
5. Utilities and common expenses
Who pays for water, electricity, internet, IUSI (property tax), maintenance fees (in horizontal property condos), minor repairs, major repairs. The default rule of the Civil Code places many expenses on the landlord, but the parties can agree otherwise.
6. Improvements and modifications
If the tenant is going to make improvements, the contract must spell out: which ones are authorized, who pays, what happens at the end of the contract (useful improvements that must be compensated, necessary improvements, voluntary improvements).
7. Grounds for early termination
Non-payment, improper use, breach of obligations, damage to the property, subletting without authorization. The more specific, the better.
8. Penalty clause
Agreed penalty for breach. Important to ensure that the tenant does not leave early with outstanding debt, or that the landlord does not terminate arbitrarily.
9. Special domicile and notifications
Addresses where notifications are received, especially important for eviction proceedings.
10. Submission to courts and applicable procedure
Competent courts, possibility of arbitration in commercial disputes, governing law.
Differences between residential, commercial and industrial leases
Residential (urban housing)
The Tenancy Law applies. It has special rules that are more protective of the tenant: legal renewal rights, restrictions on rent increases, longer eviction notice periods.
Commercial
The Commercial Code applies, with the Civil Code as supplementary law. Greater contractual freedom. Typical terms of 3–5 years with renewal options. Common clauses: exclusivity of use, non-competition, right of first refusal.
Industrial or warehouse
Similar to commercial. Pay special attention to: zoning compliance, environmental permits, structural capacity, electrical installations, waste management.
When to elevate to public deed
The Civil Code allows for private rental agreements, but it is advisable to elevate to public deed when:
- The term is longer than three years.
- The amount involved is high or it concerns a high-value property.
- A purchase option in favor of the tenant is agreed.
- Significant improvements are planned.
- You want to register the lease with the Property Registry (RGP) for enforceability against third parties.
Typical risks without a properly drafted contract
- Defaulting tenant who is hard to evict because clear grounds were not documented.
- Lost or disputed security deposit without clear retention conditions.
- Tenant who leaves early without an enforceable penalty.
- Damage to the property with no recovery because the handover condition was not documented.
- Disputes over improvements in which the tenant claims compensation.
- Inability to raise rent in long leases without an increase clause.
- Unauthorized subleases that appear without your knowledge.
The eviction proceeding: when the breach has already happened
If your tenant does not pay or breaches the contract, the legal route is the summary eviction proceeding (desahucio). Although the law frames it as summary, in practice it can take 6–12 months with appeal. That is why prevention (a well-drafted contract, proper documentation, sufficient security deposit) is always better than cure.
Frequently asked questions
Does the rental agreement need to be registered anywhere?
It is not mandatory to register it with the Property Registry (RGP), but it is advisable when the term is longer than three years or when you want enforceability against third parties (future buyers of the property). Registration is done by public deed.
Can I increase the rent automatically each year?
Only if it is agreed in the contract. Without an express rent-increase clause, you cannot raise it unilaterally during the term of the contract. That is why the contract should include an adjustment mechanism (fixed annual, CPI-indexed, or other).
How much security deposit can I ask for?
There is no legal cap. Market practice is 1–3 months of rent. In commercial leases, additional bonds or insurance policies may be requested. What is critical is to properly document the amount and the conditions for its return.
What do I do if my tenant does not pay?
First, send a written extrajudicial demand documenting the default. Then, if they still do not pay, file a summary eviction proceeding plus enforcement of the security deposit or bond. The sooner you act, the easier it is. If your contract is well drafted, the process flows. If it is poorly drafted, it drags on significantly.
Can I evict the tenant without going to court?
No. Forced eviction without a court order is illegal — even if the tenant owes rent — and may result in criminal complaints (trespassing, coercion). The only legal route is a court eviction proceeding.
Who pays for utilities and the IUSI?
By default, the landlord pays the IUSI; utilities (water, electricity, etc.) are paid by the tenant. But it can all be agreed otherwise. The critical thing is that it be expressly stated in the contract. Without a clear agreement, the default rule of the Civil Code applies.
Do I need a notary public to sign the contract?
It is not mandatory for short-term leases. For terms longer than three years or high amounts, we recommend elevating the contract to a public deed. Even in private contracts, it is advisable to authenticate the signatures to establish a certain date.
