Implied Renewal of a Lease Agreement: 2026 Guide

Tacit renewal is one of the most significant mechanisms in the field of lease agreements, often raising questions among both landlords and tenants. It is a legal concept that takes effect automatically, extending the term of a lease agreement once its initial term has expired, without the need for a new express agreement between the parties.

Its application can significantly affect the rights and obligations of both parties, influencing factors such as the term of the lease, the rent, and even the landlord’s ability to reclaim the property.

In this updated guide, we’ll take a detailed look at what the law says, what requirements must be met, how long this arrangement can last, and what the implications are for landlords and tenants. We’ll also provide practical tips on how to avoid automatic renewal when it’s not desired.

What is tacit renewal?

Tacit renewal is a legal concept that allows for the automatic extension of a lease agreement once its initial term has expired, provided that neither party expresses a desire to terminate it.

Unlike a voluntary extension, in which both parties agree to renew the lease, tacit renewal takes effect without the need for a new express agreement. It is sufficient for the tenant to continue occupying the property and paying rent, and for the landlord to accept this, for the lease to be renewed under the same terms or with the modifications provided for by law.

What does the law say about automatic renewal?

In Spain, tacit renewal is governed by Article 1566 of the Civil Code, which provides that: "Upon expiration of the lease, if the tenant continues to occupy the leased property for more than fifteen days with the landlord’s acquiescence, the contract shall be deemed renewed for the term specified in the preceding articles, and so on."

In addition, the Urban Leasehold Act (LAU) also addresses this situation in Article 9, which applies to residential leases. According to this provision, if the tenant remains in the property after the term ends and the landlord does not object, the lease is automatically renewed for one-year terms (in residential leases) or as initially agreed (in leases for non-residential use).

What are the requirements for its existence?

Expiration of the initial contract term

The lease agreement must have reached its original expiration date without having been expressly renewed through a new agreement between the parties. This applies both to fixed-term leases (for example, one year) and to those without a fixed term but where the landlord decides to terminate the agreement.

The tenant's continued use and enjoyment of the property

The tenant must continue to occupy the residence or premises after the contract’s expiration date, thereby demonstrating their intention to remain. This continued use is primarily evidenced by the payment and acceptance of rent in the months following the expiration date, the maintenance of utilities (electricity, water, etc.) in the tenant’s name, and the tenant’s lack of intention to vacate the property.

Implied consent of the landlord

The landlord must not actively oppose the continuation of the lease. This implied consent is presumed when the landlord collects rent for the period following the expiration of the lease, when the landlord does not take legal action to recover the property (such as filing an eviction lawsuit), and when the landlord does not communicate in writing their decision not to renew the lease before its expiration.

No provision to the contrary in the original contract

Some leases include clauses that explicitly exclude tacit renewal, thereby stipulating that the lease will definitively end on a specific date without the possibility of automatic extension. In such cases, the tenant’s continued occupancy of the property could be considered unlawful occupation rather than tacit renewal.

When does it apply?

In residential lease agreements, this applies when the tenant continues to live in the property after the initial term has expired, or if the landlord fails to give notice of their intention not to renew the lease with the legally required advance notice (typically 30 days for residential leases).

For leases of non-residential properties (commercial spaces, offices, etc.), this applies if the tenant continues to conduct business on the premises and the landlord does not demand eviction, and when there is no automatic termination clause at the end of the lease term.

In verbal leases or leases without a fixed term, if the tenant has been occupying the property for some time without a written lease and the landlord accepts the rent payments, it may be understood that there is a tacit lease that is renewed annually.

This does not apply when the landlord provides written notice of their intention not to renew the lease (via certified mail, email with a read receipt, etc.), if the lease contains an express clause prohibiting automatic renewal, or in cases where the landlord evicts the tenant due to their own need (such as reclaiming the property for their own use).

How long can a tacit renewal last?

The duration of tacit renewal varies depending on the type of contract. In residential lease agreements, pursuant to Article 9 of the LAU, the contract is renewed for successive one-year terms unless either party expresses a desire to terminate it, which means that, in theory, the contract could continue indefinitely if the landlord does not take steps to terminate it.

For leases of non-residential properties (commercial spaces, warehouses, etc.), the terms of the original lease agreement apply; if there is no express agreement, the Civil Code (Art. 1566) provides that the lease shall be renewed on an annual or monthly basis, depending on the frequency of rent payments (for example, if rent is paid monthly, the lease shall be renewed on a month-to-month basis).

There is no maximum term, but the landlord can always terminate the lease by giving the required notice. In practice, many tacitly renewed leases last between 1 and 5 years before either party decides to terminate them.

Difference between tacit extension and renewal

Legal consequences and main implications

For the tenant, tacit renewal entails the right to remain in the dwelling without the need for a new lease, the maintenance of the original terms and conditions—except for rent increases based on the CPI or as agreed—and protection against sudden evictions, since the landlord must comply with the required notice periods.

For the landlord, it is more difficult to reclaim the property if they do not act in a timely manner; they have the option to increase the rent as agreed in the initial lease (although in some cases the LAU limits such increases); and they run the risk that the tenant may acquire long-term rights, especially in primary residences.

The tax and registration implications are that a tacitly renewed lease does not need to be registered with the Land Registry, but it remains valid, and the rental income received must be reported on the landlord’s income tax return.

How to Avoid Automatic Renewal

If the landlord does not wish for the lease to be automatically renewed, they must provide advance notice of non-renewal by sending a certified notice (certified fax, email with read receipt) at least 30 days before the lease expires (for residential properties). For commercial properties, the notice period may be longer (please refer to the original lease agreement).

You should not accept payments after the due date; if the tenant attempts to pay after the termination date, the landlord must refuse the payment or accept it "with reservations," stating that it does not imply an extension.

You may initiate eviction proceedings if necessary; if the tenant does not vacate the property, the landlord may file a lawsuit to evict the tenant upon the expiration of the lease.

The original lease may stipulate that there will be no automatic renewal, requiring the tenant to vacate the premises upon expiration.
