Difference between plot segregation and plot division in Spain
A plot segregation is the procedure by which pieces of land are extracted and converted in single and independent smaller plot. It should not be confused with a plot division as in the segregation the original plot continues to exist, but in the division it disappears.
Esentially, when segregating a plot, we consider the initial land the parent or the matrix land. One or more parts of the matrix are extracted, resulting in new smaller plots. The matrix, by losing pieces, will evidently end up with a smaller size, but it'll remain the same land, which won't be removed from the registry. After the segregation process, the matrix can be called the primitive plot or rest plot.
When dividing a plot: the land that originally exists in the registry is deleted, creating several new ones. In this case, the parent or matrix and original plot will disappear.
