The project aims to: contribute to an effective application of EU family law for cross-border couples; offer e-learning courses and materials concerning twins Regulations; create a cross-border network of EU legal professionals specialized in twins Regulations and improve their cooperation. The project will develop on MOODLE platform a pilot course for at least 200 professionals from the partner countries. After the pilot, trainees will be invited to role play in cross-professional and cross-border activities. Then, the course will be enriched and revised to become a Massive On line Course (MOOC) available on self platform EDUOPEN. The MOOC will be attended by at least 500 professionals from all European countries and it will remain available free of charge for at least two years after the project closure.
