The institution which has provisionally received contributions from a legal and/or natural person shall not reimburse the amounts in question to the person who paid them until it has ascertained from the institution identified as being competent the sums due to it under Article 6(4) of the implementing Regulation.
Upon request of the institution identified as being competent, which shall be made at the latest three months after the applicable legislation has been determined, the institution that has provisionally received contributions shall transfer them to the institution identified as being competent for that period for the purpose of settling the situation concerning the contributions owed by the legal and/or natural person to it. The contributions transferred shall be retroactively deemed as having been paid to the institution identified as being competent.
If the amount of provisionally paid contributions exceeds the amount the legal and/or natural person owes to the institution identified as being competent, the institution which provisionally received contributions shall reimburse the amount in excess to the legal and/or natural person concerned.
