Sales Contract Basics
Sales contracts involve transferring ownership of specific things for money. They're principal (stand alone), onerous (for valuable consideration), bilateral (both parties have duties), commutative (equal exchanges), consensual (perfected by agreement), and nominate (specifically defined by law).
Like all contracts, sales need consent, object, and price. The object must be legal and transferable. Price must be certain - fixed by agreement, reference to other things, court decision, or third party designation.
Distinguish sales from barter (property for property) and contracts for work (specially manufactured items). In mixed exchanges, compare values - if money exceeds property value, it's a sale.
Natural elements are automatically included unless excluded: warranties against eviction (losing the property to someone with better rights), hidden defects (undisclosed problems), unregistered encumbrances, and merchantability (reasonable quality).
Smart Tip: Always clarify whether you're buying existing items (sale) or commissioning custom work (contract for work) - different rules apply!
