Practical use cases

1

Co-owner in Pamiers: party wall with neighbour

Mr. Dupont, a co-owner in Pamiers, owns a lot with exclusive use of a piece of land. A wall separates his property from the neighbour's. The neighbour wishes to purchase the party wall rights. The co-ownership regulations state that the ground is common property.

Practical application:

Mr. Dupont cannot receive the price alone. He must share it with all co-owners. Advice: check the co-ownership regulations before any transaction.

2

Purchaser in Saint-Gaudens: undeclared party wall

Mrs. Martin buys a house in Saint-Gaudens. A wall separates her garden from that of the neighbour. The sale deed does not mention the party wall. The neighbour claims half the price for having acquired party wall rights.

Practical application:

If the wall is on common property, the price must be shared. Mrs. Martin must check the co-ownership regulations and the sale deed. If in doubt, consult a lawyer.

3

Property developer: building a wall on the boundary

A developer builds a building in Toulouse. The boundary wall is a party wall with the neighbour. The neighbour transfers his party wall rights. The developer pays the price to a single co-owner.

Practical application:

Risk of nullity of the transfer if the ground is common property. The developer must ensure that the seller has the right to receive the price alone. Better to reach an agreement with the co-owners' association.
