Mandatory Information for a Compliant Portuguese Lease Contract

A Portuguese landlord once told us he'd been renting out his Lisbon apartment for years using a one-page Word document. It covered the basics — names, rent, and a signature. Then a dispute arose over a broken appliance, and he discovered his contract was missing half the information required by Portuguese law. The result: months of costly litigation that a proper contract would have avoided entirely.

This isn't unusual. Many landlords — especially those renting to international tenants — underestimate what Portuguese law actually requires in a lease contract. The NRAU (Novo Regime do Arrendamento Urbano) sets clear rules, and missing even one mandatory element can leave both sides exposed.

Here's exactly what your contract must include.

Identification of the Parties#

Every valid Portuguese lease contract must clearly identify both the landlord and tenant with the following information:

For Individuals (Natural Persons)#

• Full legal name (as it appears on official documents)
• Tax identification number (NIF)
• Identity document type and number (ID card, passport, or residence permit)
• Current address
• Contact information (email and phone)

For Companies (Legal Persons)#

• Company legal name
• NIPC (tax number for companies)
• Company registration number
• Registered office address
• Name and position of the legal representative

Property Identification#

The rental property must be described in sufficient detail to be uniquely identifiable:

• Complete address: Street, number, floor, door (if applicable), postal code, and parish
• Property matrix article number (from the Finanças register)
• Urban property certificate number (from the Conservatória)
• Licensed use: Habitation, commerce, mixed use, etc.
• Property condition: Furnished, unfurnished, or semi-furnished
• Common areas included: Parking, storage, garden access, etc.

Rent and Payment Terms#

Portuguese law requires clear specification of:

1. Monthly rent amount (in euros)
2. Payment deadline (typically the first 8 days of each month)
3. Payment method (bank transfer, direct debit, etc.)
4. Bank account details for transfers
5. Annual update clause (tied to the INE inflation coefficient)

The Coefficient Update#

Under Portuguese law (Article 1077 of the Civil Code), rent can be updated annually according to the official coefficient published by INE (National Statistics Institute). Your contract should specify:

• Whether annual updates will apply
• The reference month for calculating updates
• How updates will be communicated

For a deep dive into how this works in practice, see our guide on annual rent updates and the INE coefficient. You should also understand what happens when rent is paid late — our Late Payment Penalty Guide explains the 8-day grace period and the 20% penalty under Art. 1041º.

Contract Duration and Renewal#

The NRAU establishes specific rules for contract duration:

Contract Type	Minimum Duration	Notes
Fixed-term	1 year (min) to 30 years (max)	Auto-renewal unless terminated
Open-ended	No limit	Higher tenant protection
Student housing	9–12 months	Academic year
Temporary	Up to 1 year	Specific justified purpose

Security Deposit (Caução)#

If a security deposit is collected, the contract must specify:

• Amount: Maximum of 2 months' rent for residential leases (Art. 1076 CC)
• Purpose: Covering potential damages or unpaid rent
• Return conditions: Timeline and deduction criteria
• Bank deposit details: Where the deposit will be held (optional but recommended)

For everything you need to know about deposits, see our complete guide on rental deposit rules in Portugal.

Property Condition Documentation#

While not technically mandatory, we strongly recommend including:

• Detailed inventory of furniture and appliances (if furnished)
• Photos or video documentation of property condition
• Existing damage or wear and tear
• Meter readings for utilities at move-in

Signatures and Date#

The final requirement is straightforward but crucial:

• Date of signing (day, month, year)
• Location of signing
• Signatures of all parties
• Witness signatures (optional but recommended)

Frequently Asked Questions#

Create Your Compliant Lease in Minutes#

Ensuring your lease contract includes all mandatory information doesn't have to be complicated. CompliantLease automatically includes all legally required fields and generates bilingual (Portuguese/English) contracts that meet every NRAU requirement.

Two often-overlooked mandatory elements: the energy certificate (required under DL 118/2013 with fines up to €3,740 for non-compliance) and spouse consent when leasing community property or the family home under Article 1682-A of the Civil Code. While not strictly mandatory, documenting the property's state with a property condition report is strongly recommended — without one, Article 1043º CC presumes the property was delivered in good condition. If your lease requires a guarantor, see the guarantor requirements guide for the legal implications.
