I had a contract with a person from Slovenia, for her to do a service for me. There was a contract conducted in Slovenia and another conducted in Spain. The person in question is a Slovenian citizen, but had Spanish residency and status of Autonomo at the time of the signing of second (Spanish) contract.
The service of both contracts were paid in advance, yet that person did not fulfill the services (obligations) from her part of the contract. She closed the Autonomo and left Spain. What legal steps can I take to enforce the fulfillment of the contract or to get her to return the money and the damage she caused by not fulfilling the contract?
In which Spanish law is the obligation system stated and in which law do I find definitions of fraud?
