What is the difference between ASL and co-ownership?
When you acquire a property, you may encounter complex legal structures such as the Free Syndical Association (ASL) or the co-ownership syndicate. Although these two entities aim to manage common areas, their legal regimes, operating methods, and implications for owners differ significantly. Understanding these distinctions is essential to avoid unpleasant surprises, particularly regarding charges,
What is a co-ownership?
Condominium ownership is governed by the law of July 10, 1965. It concerns a built building or a group of buildings whose ownership is divided among several persons, into lots comprising a private part (apartment, cellar, parking space) and a share of common areas (hall, roof, staircases). The syndicate of co-owners is a private legal entity whose mission is to manage the building, administer the common areas, and collect charges. Each co-owner
What is a Free Syndical Association (ASL)?
The ASL is governed by the ordinance of July 1, 2004 (Articles L. 315-1 et seq. of the Urban Planning Code). It is a legal entity under private law formed by owners of land or buildings, for the purpose of creating, managing, and maintaining common facilities (roads, green spaces, networks, lighting). Unlike co-ownership, the ASL is not linked to the ownership of private lots. It is often created in the context of subdivisions, planned development zones
The fundamental differences between ASL and co-ownership
1. Legal nature and purpose
The condominium has the purpose of managing a built building and its common areas. The ASL, on the other hand, has the purpose of managing common facilities for several separate properties (land or individual houses). The ASL does not manage common areas within the meaning of the 1965 law, but so-called "common" assets which may be land or structures.
2. Membership and exit
In a condominium, membership in the syndicate is automatic and inseparable from ownership of a unit. You cannot "leave" the condominium without selling your property. In an ASL, membership is initially free, but once the land is sold with a clause of membership in the ASL, it becomes perpetual and attached to the plot. Exiting is almost impossible without amending the articles of association or dissolving the association.
3. Decision-making and voting
In a condominium, voting is based on shares (surface area of the unit). Decisions are taken by simple majority, absolute majority or double majority depending on their importance. In an ASL, voting is generally based on the principle of "one vote per owner" or on a weighting provided for in the articles of association (often linked to the land area). The majority rules are freely set by the articles of association, which offers great flexibility but also a risk of deadlock.
4. Charges and recovery
In co-ownership, charges are allocated according to shares and recovery is regulated by law (possibility of seizure, legal mortgage). The syndicate has strong coercive powers. In an ASL, charges are allocated according to the bylaws (pro rata to area or flat rate). Recovery is less regulated: the ASL can take legal action to obtain payment, but does not have the same privileges as a co-ownership syndicate (no legal mortgage).
5. Tax regime
The co-ownership is not taxable on its income (except in certain cases). The ASL may be subject to corporate tax if it carries out a lucrative activity (e.g., renting equipment). In practice, most ASLs are non-profit and therefore non-taxable, but caution is required.
When do we talk about ASL and when about co-ownership?
The distinction is sometimes blurred, particularly in "residences" with common areas (parking, garden) and collective facilities (heating, swimming pool). If the building is constructed and divided into private lots with common areas, it is a condominium. If you have a detached house with land, and you share a road or green space with your neighbors, it is likely an ASL. Caution: there are also "condominium ASLs" (or management ASLs) that manage
What are the risks for an owner?
The main risk for an owner is not knowing which regime they are subject to. In an ASL, the bylaws may provide for very high charges, unfavorable voting rules, or an impossibility to exit
