Home-Based Work Contract Spain (Contrato de Trabajo a Domicilio)

A Home-Based Work Contract Spain (Contrato de Trabajo a Domicilio) is an employment agreement governed by Article 13 of the Estatuto de los Trabajadores (Real Decreto Legislativo 2/2015 — ET) under which an employer (empresario) and an employee (trabajador a domicilio) agree that the employee will perform their work habitually at their own home (domicilio) or at another freely chosen place, outside the employer's business premises, without the supervision of the employer in their physical execution. Article 13 ET defines trabajo a domicilio as work performed by the worker at home or at a place freely chosen by them, without supervision by the employer, that does not primarily involve the use of information and communication technology (ICT) — this last characteristic is what distinguishes the Contrato de Trabajo a Domicilio from telework (teletrabajo) governed by Ley 10/2021 de Trabajo a Distancia.

The distinction between trabajo a domicilio (Article 13 ET) and trabajo a distancia or teletrabajo (Ley 10/2021) is fundamental in Spanish employment law. Article 13 ET — the traditional home work contract — applies to workers who perform manual, craft, or non-ICT professional tasks at home: garment stitching and textile work, handicraft assembly, jewellery work, bookbinding, envelope packaging, translation and writing using non-digital methods, or other piece-rate manual work. Ley 10/2021, by contrast, governs distance work performed using ICT — computer-based professional services, software development, customer service via digital platforms. Where the work primarily involves ICT use, Ley 10/2021 applies mandatorily; where it is manual or non-ICT-based work at home, Article 13 ET applies.

The Contrato de Trabajo a Domicilio is not merely a historical relic — Article 13 ET was updated by the Real Decreto-Ley 32/2021 (2021 Labour Reform) to reinforce equal treatment protections. Article 13.2 ET establishes explicitly that trabajadores a domicilio have the right to receive at least the same remuneration (retribución) established by the applicable collective agreement (convenio colectivo) for the same work performed in the employer's premises — the parity rule (principio de equiparación retributiva) prohibits paying home workers a lower rate than in-house workers for equivalent output.

Material and tool provision is a key obligation of the employer under Article 13.3 ET — the employer must provide the home worker with all necessary raw materials (materias primas), tools, and equipment required to perform the work. The costs of wear and tear of any tools or materials belonging to the worker are for the employer's account, and the employer must reimburse the worker for materials consumed. This provision distinguishes the employment relationship from a commercial service contract with an autónomo, where the service provider supplies their own tools.

Occupational health and safety protections for home workers are established by Article 13.4 ET in conjunction with Ley 31/1995 de Prevención de Riesgos Laborales (LPRL). The employer has a duty to conduct a risk assessment (evaluación de riesgos) of the work performed by the home worker — including the tools and materials used and the physical conditions of the work area. This requires the employer's health and safety service or prevention technician to assess risks in the home environment, with the worker's consent, and to adopt appropriate preventive measures. The Inspección de Trabajo y Seguridad Social (ITSS) monitors compliance with LPRL obligations for home workers.

Social security registration obligations under the Ley General de la Seguridad Social (RDL 8/2015) apply to home workers in the same manner as other employees — the employer must register the home worker with the TGSS under the employer's Código de Cuenta de Cotización (CCC) before work commences, and must make monthly social security contributions for the worker. The SEPE contract registration requirement under Article 16.1 ET applies equally to home work contracts.

A Home-Based Work Contract Spain is required whenever an employer engages a worker to perform habitual work at the worker's home using non-ICT methods, formalising an employment relationship (rather than a commercial arrangement with an autónomo) that is subject to the protections of Article 13 ET.

A Contrato de Trabajo a Domicilio is needed when a textile manufacturer (fabricante textil), garment producer, or craft workshop assigns sewing, embroidery, assembly, or finishing work to workers who perform these tasks at home — a common arrangement in Spain's garment-producing regions (Galicia, Valencia, Cataluña) where small home workers supplement factory production. The home work contract formalises the employment relationship, confirming social security registration and compliance with sector convenio pay rates.

The contract is required when a publisher, translation agency, or media company engages a worker to perform editing, proofreading, or non-digital translation tasks from home on an ongoing basis — where the work is repetitive, volume-based, and not primarily ICT-driven, the Article 13 ET framework applies rather than Ley 10/2021, and the worker must be registered as an employee rather than an autónomo.

A home work contract is needed when an artisan (artesano) or craftsperson performs piece-rate work for a single principal client as their primary economic activity — under the criteria developed by the Tribunal Supremo for distinguishing employment from self-employment (criterios de laboralidad under Article 1.1 ET), an artisan who works exclusively for one client, uses the client's materials, and has no commercial risk may be reclassified as an employee by the ITSS.

The agreement is required when a company wishes to formalise an existing home work arrangement that was previously undocumented — the Article 13 ET written contract requirement is mandatory, and undocumented home workers may claim employment status retroactively through the Juzgado de lo Social, with consequent social security and back-pay obligations for the employer.

A Contrato de Trabajo a Domicilio is also needed when a worker requests to perform manual or non-ICT work from home as an accommodation for disability, chronic illness, or mobility impairment — such requests are considered under the reasonable accommodation obligation (ajustes razonables) of Ley General de Derechos de las Personas con Discapacidad (Real Decreto Legislativo 1/2013), and the home work contract formalises the agreed arrangement.

Under the Estatuto de los Trabajadores (ET) RDL 2/2015, Spanish employment law governs contracts, dismissals, and working conditions. The Tesorería General de la Seguridad Social (TGSS) administers social security contributions. The Servicio Público de Empleo Estatal (SEPE) manages unemployment benefits. The Inspección de Trabajo y Seguridad Social enforces labour compliance. The Juzgados de lo Social hear employment disputes under the Ley Reguladora de la Jurisdicción Social (Ley 36/2011).

A valid Home-Based Work Contract Spain under Estatuto de los Trabajadores Article 13 must contain the following essential elements to comply with the ET's mandatory provisions and protect both the employer and the home worker.

Identification of Parties: Full legal name, DNI/NIE/NIF, and address of the employer (empresario) and the home worker (trabajador a domicilio), together with the employer's TGSS CCC and the worker's Social Security Number (NSS). The home worker's work address (domicilio de trabajo) — typically their home address — must be specified as the primary work location.

Description of Work: A precise description of the work to be performed at home — the specific tasks, the product to be produced or service to be delivered, and the technical specifications or quality standards required. The method of measuring output — by piece (destajo), by hour (por horas), or by assignment — must be specified, as this determines how the Article 13.2 ET remuneration parity obligation is calculated and verified.

Remuneration and Pay Parity: The agreed rate of pay — whether hourly, piece-rate (por pieza), or output-based — confirmed to be at least equal to the remuneration established by the applicable collective agreement (convenio colectivo) for the same work performed at the employer's premises. Article 13.2 ET requires that home workers receive at least the same pay as comparable in-house workers for equivalent work — this is mandatory and cannot be waived by either party. The payment frequency (monthly, bi-weekly) and payment method must be stated.

Material and Tool Provision: An inventory of all raw materials (materias primas), tools, machinery, and supplies that the employer will provide to the home worker, together with the procedure for delivery and collection. The employer's obligation to bear the cost of materials consumed, wear and tear of employer-provided tools, and damage to materials occurring without the worker's negligence must be addressed. Any security deposit (fianza) for valuable tools or materials must be agreed and documented.

Work Volume and Schedule: The agreed minimum and maximum work volume per period — pieces per week, pages per month, etc. — and any deadlines for delivery of completed work. For Article 13 ET home work, the concept of a fixed daily schedule is less applicable than for office work, but the agreed workload must be realistic and compliant with the maximum working time limits of Article 34 ET on an annualised basis.

Occupational Safety: The employer's obligation to conduct a risk assessment of the home work activities under Article 16 LPRL and to adopt appropriate preventive measures. The worker's obligation to maintain the work area in safe conditions and to notify the employer of any work-related accident or occupational disease through the standard accident notification procedure (parte de accidente) under the LGSS.

SEPE Registration and Social Security: Confirmation that the contract will be registered with the SEPE within 10 working days under Article 16.1 ET and that the worker will be registered with the TGSS under the employer's CCC before work commences. Home workers are registered under the Régimen General de la Seguridad Social — not the Régimen Especial de Trabajadores Autónomos (RETA) — confirming their employee status.

Forms-legal.com provides this Home-Based Work Contract Spain template as a practical reference. Employers must distinguish carefully between genuine Article 13 ET home work employment contracts and commercial agreements with autónomos — misclassification (falsos autónomos) is a priority enforcement target of the Inspección de Trabajo y Seguridad Social (ITSS), with sanctions including back social security contributions, fines, and regularisation orders.

Under the Estatuto de los Trabajadores (RDL 2/2015) Article 13, home-based workers have full employment rights. The Ley 31/1995 LPRL requires risk assessments even in the home. The Tesorería General de la Seguridad Social (TGSS) administers contributions. The Inspección de Trabajo y Seguridad Social (ITSS) monitors falsos autónomos. The Juzgados de lo Social resolve home work employment disputes.
