Yes. While selling a lot of co-ownership, the seller must present to the notary a certificate from the property administrator, which is dated less than a month, attesting that he is free of any obligation with regard to the unions.
Otherwise, the notary must notify the trustee that the co-owner has sold his property.
The trustee then has a period of 15 days after receiving this transfer notice to oppose the payment of funds to the seller within the limit of the sums that are due.
The notary can distribute the funds as soon as he has obtained an agreement between the trustee and the owner on the sums remaining due. If the parties fail to reach an agreement within 3 months of the opposition, the notary pays the sums that remain due to the trustee, unless there is a challenge to this opposition before the courts by one of the parties (art. 20, I, Law n°65-557 of July 10, 1965).
