Anonymized constellations from real estate mandates in Mallorca and Spain.
Situation: A property was marketed as a house, but only a garage was registered in the land registry.
Approach: We reviewed notarial declarations, rezoning options and required building permits before signing.
Result: The clients identified significant cost risk early and could decide safely.
Situation: Before purchase, planned refurbishments in the owners' association were not yet transparent.
Approach: We requested meeting minutes and clarified relevant points directly with the community.
Result: Financial consequences were realistically assessed and included in the purchase decision.
Situation: For an older building, it was unclear whether an ITE inspection and measures were imminent.
Approach: We reviewed documentation on building condition and potential mandatory measures in advance.
Result: Clients gained clarity on effort, timeline and budget before proceeding.
Regularly refined content from LinkedIn posts on real estate and inheritance law in Spain.
Before signing, the arras contract, land registry status, encumbrances and liability risks should be reviewed legally.
A notarial declaration alone does not replace urban-planning and land-registry legalization of residential use.
For estates connected to Spain, precise coordination between inheritance law, registry issues and tax handling is essential.
