Dear Muroms:
It seems an excessive charge for Notary fees to me and of course, they are subject to specification and you can claim on any excess.
You have a calculator here ( in Spanish though): https://www.ocu.org/inversiones/aspx/calculators/notary/?5
In 2010 , the Spanish Government included a reduction of 5% on fees charged by notaries and Property registrars in relation to documents where value is expressed such as deeds of house purchase.
This has been made in the recent decree of extraordinary measures to reduce the deficit.
This was the scale till then:
Until 6,010.12--------------------------------------------------90.15 euros
Between 6,010.13 and 30050.60 euros-------------------------- 4.5 per 1,000
Between 30,050.61 and 60,101.21 euro------------------------- 1.50 per 1,000
Between 60,101.22 and 150,253.03euros-------------------------- 1 per 1,000
Between 150,253.04 and 601,012.10 euros----------------------- 0.5 per 1,000.
Between 601,012.11 and 6,010,121.04 euros-------------------- 0.3 per 1,000
From 6,010,121.05: the amount that may be freely agreed by the parties.
