Just wondering how easy the Spanish Consumers Law is to uphold or might it still need legal action especially when a contract states;
changes which are deemed necessary or convenient by the Architect managing the building works may be made, provided they do not affect in a direct and essential manner the property and the building features are neither altered nor imply a quality decrease.
and a client cannot fault their actual property
Sorry to ask but Consumer Laws , although they appear to be in the interest of the purchaser , are not necessarily easy to implement and often the require threat of legal action.
Just interested to know
