If you have assets in Italy, there is indeed a risk that these assets will be enforced by way of execution for all costs and interest included in the "precetto", as well as any further enforcement costs and fees. If, on the other hand, the creditor must enforce in Germany, the judgment must first be declared enforceable. This usually does not contain all the cost items listed in the "precetto", so that the creditor may not succeed in extending enforcement to these.
