How to Read a Rental Lease in Mexico, Portugal, and Thailand

In Canada, you probably signed a standard Ontario or BC lease form — a government-issued template that spells out your rights in plain English. Abroad, there is no standard form. Leases might be in Spanish, Portuguese, or Thai. They might be two pages or twenty. They might be handwritten on a napkin, or they might not exist at all.

This guide walks through what a rental contract looks like in each country, what to watch for, and what to insist on before you hand over your deposit. If you’re renting abroad for the first time, read this before you sign anything.

The Universal Rules (All Three Countries)

Before the country-specific details, here are the non-negotiables that apply everywhere:

  1. Get it in writing. Verbal agreements are common in expat rentals. Don’t rely on them. A written contract is your only protection if something goes wrong — and it’s required for visa applications in Portugal.
  2. Get a translation. If the lease is in a language you don’t read fluently, get it translated before signing. Not after. A bilingual friend, a paid translator, or Google Translate as a rough first pass — anything is better than signing blind. In Portugal, ask for a bilingual version; many agents will provide one.
  3. Photograph the apartment before moving in. Take dated photos of every room, every wall, every scratch, every appliance. Email them to the landlord the day you move in. This is your evidence when the deposit return is disputed — and deposits are disputed constantly.
  4. Get a receipt for every payment. Cash is common in all three countries. Receipts are not. Insist on a written receipt for your deposit, advance rent, and any other payment. A WhatsApp message confirming the amount works if a formal receipt isn’t available.
  5. Understand the currency. Your lease amount will be in MXN, EUR, or THB. Know the conversion to CAD and understand that it will fluctuate. Some landlords in expat areas quote in USD — convert to CAD yourself, and confirm which currency the actual payments will be in. Use Wise for transfers to avoid 2-4% bank spreads.

Mexico: What Your Lease Should Say

The Basics

Mexican rental contracts (contrato de arrendamiento) are governed by each state’s civil code, so rules vary slightly between Jalisco (Guadalajara, Lake Chapala), Mexico City, and Quintana Roo (Cancún, Playa del Carmen). But the general structure is consistent.

A standard Mexican lease includes:

  • Names and identification of both parties (you’ll need your passport)
  • Property address and description
  • Monthly rent amount and payment date
  • Deposit amount and return conditions
  • Lease term (typically 12 months, sometimes 6)
  • What’s included (furniture, appliances — get this inventoried)
  • Who pays utilities

Deposit

Standard: 1-2 months’ rent. Plus first month upfront. So on a $12,000 MXN/month apartment (~$900 CAD), expect to pay $24,000-36,000 MXN ($1,800-2,700 CAD) before you sleep a single night.

The deposit is supposed to be returned within 30 days of move-out, minus documented damages. In practice, getting your full deposit back in Mexico requires: (a) the move-in photos we mentioned, (b) a written inventory signed by both parties, and (c) persistence. Many landlords will try to deduct for “normal wear and tear” that shouldn’t be your responsibility. Push back politely but firmly.

Watch For

  • The aval (guarantor) requirement. Some landlords require a Mexican citizen to co-sign as a financial guarantor who owns property in the same state. As a foreigner, you likely don’t have one. Workarounds: offer additional months’ deposit, pay several months upfront, or use a property management company that waives this requirement. Expat-friendly landlords usually don’t require an aval.
  • Rent increases. No legal cap in most states. Your contract should specify whether rent increases at renewal and by how much. If the contract is silent, the landlord can raise it to whatever the market bears. Get a clause that caps annual increases (5-10% is fair).
  • Early termination. Most leases have a penalty clause — typically 1-2 months’ rent for breaking the lease early. Read this carefully. If your plans are uncertain, negotiate a shorter initial term or a lower penalty.
  • Utility responsibility. In many Mexican rentals, the landlord’s name stays on the CFE (electricity) and water accounts. You pay the bills, but they receive them. Get clarity on how bills reach you and what happens if one is late.

Portugal: What Your Lease Should Say

The Basics

Portuguese rental law (Lei do Arrendamento Urbano) is the most tenant-friendly of the three countries. Contracts are more formal, and your rights as a tenant are stronger — but only if you have a proper written lease.

A Portuguese lease (contrato de arrendamento) must include:

  • Identification of both parties (NIF required — get yours first)
  • Property address, including the floor and fração (unit letter)
  • Lease purpose (habitation)
  • Monthly rent and payment method
  • Term: fixed (prazo certo) or open-ended (duração indeterminada)
  • Start date

Important: Your lease must be registered with the Portuguese tax authority (Finanças) by the landlord. This registration is required by law, and you need it to apply for the D7 visa. If the landlord refuses to register the contract, that’s a red flag — they may be avoiding taxes.

Deposit

Standard: 2 months’ rent. Plus first month. On a 900 EUR/month apartment (~$1,400 CAD), that’s 2,700 EUR (~$4,150 CAD) upfront.

Portuguese law limits the deposit to a maximum of 2 months’ rent for contracts under 6 years. The landlord must return it within a reasonable period after move-out (typically 30 days), with documented deductions only for actual damages beyond normal wear.

Watch For

  • The NIF catch-22. You need a NIF (tax identification number) to sign a lease, but some landlords want a signed lease before you arrive. Solution: get your NIF through a fiscal representative before you arrive (costs $100-200 CAD), or apply in person at a Finanças office in your first week. Some agencies will hold an apartment with a small reservation fee while you sort the NIF. More on arriving in Lisbon.
  • Rent increase caps. For existing contracts, annual increases are limited by a government-set coefficient tied to inflation — for 2026, the cap is 2.24%. Your landlord cannot raise rent above this rate during a fixed-term contract. However, if your landlord hasn’t raised rent in three or more years, they can apply accumulated coefficients at once — potentially exceeding 10% in a single adjustment.
  • Fixed vs. open-ended. Fixed-term contracts (1-3 years typical) auto-renew unless either party gives notice. Open-ended contracts offer the tenant more protection but are less common for expats. As a D7 visa holder, you generally want a fixed-term contract of at least 12 months.
  • The recibo de renda. Landlords must issue an electronic rent receipt through the Finanças portal for every payment. You need these receipts for your tax declaration and visa renewals. If your landlord doesn’t issue them, they’re operating off the books — and you lose legal protection.
  • Notice periods. To end a fixed-term lease, the tenant must give notice 120 days before the end of the contract (for contracts of 6+ months). Miss this window and the contract auto-renews. Mark your calendar.

Thailand: What Your Lease Should Say

The Basics

Thai rental culture is the most informal of the three, particularly for condos. Many rentals — especially furnished condos popular with expats — operate on simple one-page agreements. This can feel refreshingly easy after Portuguese bureaucracy, but it also means fewer built-in protections.

A standard Thai rental agreement includes:

  • Names and passport details of both parties
  • Property address and unit number
  • Monthly rent and payment date (usually the 1st or 5th)
  • Deposit amount and return conditions
  • Lease term (typically 12 months; 6-month available at a premium)
  • Included furniture and appliances
  • House rules (many condos have building rules about guests, noise, cooking smells)

Deposit

Standard: 2 months’ rent advance + 1 month deposit. Some buildings ask for 2 months’ deposit. On a 15,000 THB/month condo (~$600 CAD), expect 45,000 THB (~$1,800 CAD) upfront.

Deposit disputes are common in Thailand. The most frequent complaint from expats: landlords deducting for “cleaning fees” or minor wear that was there before move-in. Your protection is the same as everywhere — move-in photos, dated and shared with the landlord.

Thai law requires deposit return within 7 days of move-out for leases of 3+ years. For shorter leases (most expat rentals), the timeline is whatever the contract states — usually 30 days. If your contract is silent, you have less leverage.

Watch For

  • Electricity markup. This is the single most common gotcha in Thai rentals. The Metropolitan Electricity Authority (MEA) charges about 4-5 THB/unit. Many condo buildings and landlords charge 7-9 THB/unit — effectively doubling your electricity cost. In a month where you run the air conditioning regularly, this markup can add 1,500-3,000 THB ($60-120 CAD) to your bill. Ask about the per-unit electricity rate before signing. Some expats specifically seek buildings that pass through MEA rates directly.
  • Lease registration. Thai law requires leases of 3+ years to be registered with the Land Department. Most expat leases are 12 months and don’t require registration — but this also means less legal protection. For longer stays, consider a registered lease.
  • The 30-day rule. Foreigners staying in a condo or house must be reported to immigration within 24 hours of arrival (TM.30 form). This is technically the landlord’s responsibility, but many don’t do it. Without the TM.30, you can face problems at immigration checkpoints and when extending your visa. Confirm who handles this before signing.
  • Condo juristic rules. Thai condos have a juristic person (management body) that sets building rules. Some prohibit Airbnb-style subletting, restrict pets, limit renovation, or have quiet hours. These rules are separate from your lease and may not be mentioned in it. Ask to see the building rules before signing.
  • No rent control. Thailand has no rent increase caps. At renewal, the landlord can raise rent to market rate. The negotiation leverage is simple: good tenants who pay on time and don’t cause problems are valuable. If you’ve been a good tenant, you have room to negotiate.

The Bottom Line

A rental lease abroad is not a formality. It’s the single document that determines whether you get your $2,000-4,000 CAD deposit back, whether you can break a lease without penalty if plans change, and whether you have legal standing if something goes wrong.

Read it. Translate it. Photograph the apartment. Get receipts. And if anything feels off — the landlord won’t put it in writing, won’t register the contract, won’t give you a receipt — that’s your answer. Walk away. There are other apartments.
