Starting August 12, 2025, Spain will require an electronic signature on valuation reports under Order ECM/599/2025. If your organization operates in real estate, finance, or legal advisory in Spain, now is the time to prepare. This new rule replaces the older Order ECO/805/2003 and aligns with both Spain’s digital strategy and the EU’s eIDAS regulation.
It’s not just a digital upgrade — it’s a legal shift towards traceability, integrity, and fraud prevention in real estate processes.

Who must use electronic signature on valuation reports?
The regulation applies to all professionals involved in the creation and review of property appraisals:
- Appraisers
- Technical engineers
- Reviewers or supervisors
Order ECM/599/2025 explicitly states:
“The obligation to electronically sign the valuation report is extended to all individuals who sign the appraisal, to ensure that everyone endorses its content.”
Only advanced or qualified electronic signatures are accepted — ensuring:
- Verifiable signer identity
- Protection against tampering
- Full legal audit trail
Paper-based reports and handwritten signatures will no longer be valid in the Spanish Land Registry.
Why electronic signature on valuation reports is now mandatory
Spain’s goal is to eliminate document manipulation and increase legal transparency in real estate operations. With these changes:
- You gain legal certainty
- You reduce administrative errors
- You speed up transactions
- You comply with both national and European digital trust laws
Practical example: A German bank financing a property in Málaga
Imagine a German bank financing a home in Málaga, Spain:
- The valuation report must be signed by a certified Spanish appraiser.
- The reviewing engineer and any other technical experts must also sign.
- All signatures must be advanced or qualified, compliant with eIDAS.
- The digital process must ensure traceability, integrity, and legal validity.
Without this, the report could be rejected, delaying the financing process and exposing the deal to legal risk.
