Historically, divisible estates were the norm in most of Europe in Late Antiquity and the Early Middle Ages. By the time the High Middle Ages rolls around, England and France switch to a system of primogeniture, granting all the lands to the oldest son. However, in Germany, divisibility remained the norm. This resulted in a tendency of lands in the Holy Roman Empire to proliferate as compared to France or England.

I don't know any specifics about Hungary, but I presume that the general norm is as in Germany rather than England/France.

They aren't widely used. Parents prefer to divide property between children by donating it while they are alive.
