SANZ FERNÁNDEZ, A: “Le droit à la predilection dans l`anti-malade”, 1934 1. In the twelfth century, canon law, respected by civil law, prohibited compensatory protection on the grounds that, in most cases, it included a user agreement and because if the debt of a loan violated the prohibition of the interest pact. The Council of Tours established that the fruits of the funds donated in clothing could only be charged to the capital, so that the anti-crisis was only intended to amortize the debt. (2) The influence of canon law has determined the prohibition of anticrease, provided that the agreement of credit of fruits to the capital of the debt is authorized, provided that there was a question of “living pledge” (living clothes or shock absorbers) or “pledge” in the real estate field. They have thus left great doubts about the nature and effects of anticresis.
