Guaranteed Loan Agreement Spain (Acuerdo de Préstamo con Aval)

A Guaranteed Loan Agreement Spain (Acuerdo de Préstamo con Aval) is a formal written contract under which a lender (prestamista) advances a principal sum of money to a borrower (prestatario), with repayment secured by a third-party guarantor (avalista or fiador) who assumes personal subsidiary or joint-and-several liability for the borrower's obligations, governed by the Código Civil (Real Decreto de 24 de julio de 1889) Articles 1822 through 1856 on the fianza (personal guarantee) and Articles 1740 through 1757 on the mutuo (loan contract).

The fianza under Article 1822 of the Código Civil is defined as a contract by which a person (fiador) undertakes to pay or perform what a third party (the debtor) is bound to pay or perform, if that third party does not do so. The fianza may be convencional (agreed between the parties), legal (required by law), or judicial (ordered by a court). In commercial lending practice in Spain, the personal guarantee most commonly takes the form of an aval solidario (joint-and-several guarantee) rather than a simple subsidiary guarantee (fianza subsidiaria), waiving the fiador's right to the beneficio de excusión under Article 1830 of the Código Civil — the right to require the creditor to exhaust remedies against the borrower's assets before pursuing the guarantor.

The Banco de España, operating under Ley 13/1994 de Autonomía del Banco de España and as part of the European System of Central Banks (SEBC), supervises credit institutions in Spain that extend guaranteed loans. Consumer credit is governed by Ley 16/2011 de Contratos de Crédito al Consumo, implementing Directive 2008/48/EC, which establishes maximum APR disclosure requirements (Tasa Anual Equivalente — TAE) and a 14-day withdrawal right for consumers. Business loans are subject to Ley 5/2015 de Fomento de la Financiación Empresarial when extended by credit institutions.

The avalista under Spanish law acquires the same obligations as the borrower once the guarantee is called, subject to the accessory nature of the fianza — Article 1847 of the Código Civil provides that the fianza is extinguished when the principal obligation it secures is extinguished. The guarantor benefits from the right of subrogation (beneficio de subrogación) under Article 1839 of the Código Civil, stepping into the creditor's position against the borrower upon payment of the debt. Where multiple guarantors exist, the beneficio de división under Article 1837 of the Código Civil entitles each to pay only their proportionate share, unless they have expressly waived it.

Notarisation requirements in Spain: a préstamo con aval exceeding €30,000 or involving real property as collateral may require formalisation before a Notario as a escritura pública under the Ley del Notariado (Ley de 28 de mayo de 1862), which confers enforceability through the executive title (título ejecutivo) provisions of the Ley de Enjuiciamiento Civil (Ley 1/2000, LEC) Article 517.2.4°. Simpler private loan agreements (documentos privados) are enforceable before the Juzgado de Primera Instancia for amounts up to €6,000 in verbal proceedings (juicio verbal) and above €6,000 in ordinary proceedings (juicio ordinario) under LEC Article 250.

The Agencia Tributaria (AEAT) applies the Impuesto sobre Transmisiones Patrimoniales y Actos Jurídicos Documentados (ITP-AJD) — Ley de 28 de mayo de 1962 — to loan agreements. Under Article 15 of the ITP-AJD Reglamento (Real Decreto 828/1995), loan agreements are generally exempt from Transmisiones Patrimoniales but subject to Actos Jurídicos Documentados if formalised as notarial deeds, with the tax paid by the lender following the Tribunal Supremo judgment of 16 October 2018 and the subsequent reform by Real Decreto-Ley 17/2018.

A Guaranteed Loan Agreement Spain is required whenever a private lender or credit institution advances money to a borrower whose creditworthiness alone is considered insufficient, and a third-party guarantor is needed to secure repayment — a common structure in Spain for business loans to Sociedades Limitadas (S.L.) whose sole administrator also acts as avalista solidario, required by lenders including Banco Santander, BBVA, CaixaBank, and Sabadell.

The agreement is needed when a natural person (autónomo) or legal entity seeks financing from another private individual or non-regulated lender (préstamo particular) and both parties want documented security through a third-party guarantor to reduce collection risk and establish clear terms before the Agencia Tributaria and the Registro Civil.

A préstamo con aval is required when a Sociedad de Garantía Recíproca (SGR) — mutual guarantee societies such as CERSA (Compañía Española de Reafianzamiento), Avalis, or Iberaval — issues a formal guarantee letter on behalf of an SME borrower seeking bank credit, requiring a formal loan and guarantee agreement incorporating the SGR's specific terms under Real Decreto 2345/1996 de Sociedades de Garantía Recíproca.

The agreement is needed when Spanish public bodies — including the Instituto de Crédito Oficial (ICO), the Empresa Nacional de Innovación (ENISA), or the Ministerio de Industria — extend subsidised loan lines to companies and require a personal guarantee (aval personal) from the company's directors or shareholders as a condition of the financing.

A Guaranteed Loan Agreement is required when family members or friends in Spain lend money to relatives for home purchase, business start-up, or debt consolidation, and wish to formalise the arrangement with a guarantor to create legally enforceable rights, avoid deemed gift classification by the AEAT under Ley 29/1987 del Impuesto sobre Sucesiones y Donaciones, and document the transaction for Modelo 600 filing with the relevant Comunidad Autónoma tax authority.

The agreement is also needed upon maturity extension or restructuring of an existing Spanish loan, where the lender requires the borrower to provide a new avalista or confirm the continuing liability of an existing guarantor under the novated terms, particularly where the original guarantee has expired by its terms or become insufficient following revaluation of the loan balance.

Under the Ley Cambiaria y del Cheque (Ley 19/1985), promissory notes and bills of exchange are governed in Spain. The Banco de España supervises banking under Ley 10/2014. The Comisión Nacional del Mercado de Valores (CNMV) regulates securities markets. The AEAT administers IVA (Ley 37/1992) and IRPF (Ley 35/2006). The Ley 3/2004 governs late payment in commercial transactions with statutory interest.
