Questão jurídica principal
Who was passively legitimated as owner of the sold apartment unit at filing date: seller or journal-entered buyers?
Decisão extraída
The journal entry of the transfer made the seller no longer authorized to dispose of the unit; the buyers had to be sued, even if the main register still showed the seller.
Fundamentação extraída
For certainty in litigation, the decisive date is the journal entry, not the later main-register entry. After journal entry, the seller has already made the dispositive declaration and lost disposition power; the buyer has a protected expectancy, although ownership arises only upon main-register entry with retroactive effect.
