"Desmembramento" is a very common practice in everyday life, but few people know what it really means.
Subdivision involves dividing a large tract of land into smaller lots ready for construction, making use of existing streets—without creating new ones. If it involves creating a new street, it is considered a land development, not a subdivision.
It depends on the municipality. Each city has a minimum size requirement for subdividing property—always check local laws before making any plans.
Only a professional licensed by CREA can measure and appraise the lot. From there, he or she prepares the site plan and descriptive report required for registration.
