Lease Agreement Termination: Notice Periods and Rules in 2026


Lease Agreement Termination: Notice Periods and Rules in 2026

Landlords and tenants have different rights when it comes to ending a lease. Confusing termination by notice (denúncia), opposition to renewal and termination for breach is the number one cause of avoidable conflicts.

The essentials in 30 seconds
  • There are three ways to end a lease: opposition to renewal, termination by notice (denúncia) and termination for breach (resolução por incumprimento).
  • Communication must always be in writing and sent by a means that proves receipt.
  • The notice period depends on the length of the lease — getting the calculation wrong can force you to accept another renewal cycle.
  • Termination for non-payment has its own requirements and is the route that leads to eviction.

The problem

“I want my house back” is not enough. The way a lease is ended — and the notice period — determines whether the exit is peaceful or ends up in court (where you will need a tenancy lawyer).

The three ways to end a lease

  • Opposition to renewal (oposição à renovação) — the landlord notifies that they will not renew, with the legal notice.
  • Termination by notice (denúncia) — in open-ended leases, with specific notice periods and grounds.
  • Termination for breach (resolução por incumprimento) — when the tenant does not pay, the route that leads to eviction.

Golden rules

  • Communication must be in writing and by a means that proves receipt.
  • The notice period depends on the length of the lease.
  • Termination for non-payment has its own requirements.

The cost of getting the notice wrong

A badly calculated notice period can force the landlord to keep the tenant for another renewal cycle — months of income tied up in a tenancy they already wanted to end.
