Lease Requirements & the 30-Month Rule in Brazil

Drafting an airtight written rental contract under Brazil's Lei do Inquilinato (Tenancy Law) is the single most important defense a landlord has. Specifically, the length of the lease you choose to write will drastically dictate how easily you can evict the tenant when you want your property back.

Written Contracts vs. Verbal Agreements

In Brazil, verbal lease agreements established purely by tacit consent and a handshake are legally valid and binding in civil court. However, verbal contracts are incredibly dangerous for landlords.

By default, any residential lease made with a verbal agreement is automatically considered by courts to be an "indefinite term" lease granting the tenant immense statutory protections. A landlord cannot evict a tenant on a verbal lease without a legally compelling "just cause" (like needing to move into the house themselves) until the tenant has occupied the home for 5 uninterrupted years.

Therefore, a written and signed legal lease is absolute paramount practice.

The Definitive 30-Month Rule

The primary reason almost all residential contracts in Brazil are drafted for exactly 30 months (two and a half years) involves a legal divergence between Article 46 and Article 47.

If the written lease is 30 months or longer: When the 30-month term ends, the contract resolves automatically. The landlord can issue a 30-day notice to vacate without providing any reason or justification whatsoever. This massive landlord benefit is called an "unmotivated eviction" or denúncia vazia.

If the written lease is less than 30 months (e.g., a standard 12-month lease): When the 12-month term ends, if the tenant remains in the property and continues paying rent without the landlord immediately objecting, the contract automatically converts into an "indefinite term" lease. At this point, the landlord loses the right to the denúncia vazia. The tenant becomes protected by the "5-year rule" (denúncia cheia) and cannot be removed without just cause until five full years have elapsed.

The "12-Month Early Termination Exemption" Clause

Because a 30-month commitment is extremely long for modern tenants (especially expats or transient professionals), Brazilian landlords routinely include a standard compromise clause.

The customary lease agreement is set for 30 months to protect the landlord's eviction rights, but includes an explicit exemption clause that kicks in after the first 12 months of occupancy. Once the tenant completes the first continuous year of the lease with perfect payment history, they are granted the unilateral right to break the 30-month lease and leave at any time without paying any early termination penalty, provided they issue a 30-day written notice.

Change of Ownership: Averbação (Registration)

If you intend to sell the rental property while a tenant is inhabiting it, the new buyer can typically serve a 90-day eviction notice upon closing to take possession of the home.

However, the tenant can thwart the new buyer from terminating their remaining lease term if two conditions are met:

1. The lease includes an explicit "Vigência Requirement Clause" (stating the contract survives a sale).
2. The lease was formally registered (Averbado) in the Real Estate Registry Office (Cartório de Registro de Imóveis) connected to the property's title matrix.

If registered, the lease is impenetrable, and any new owner must respect the tenant's remaining months on the contract.
