I shall start from a very recent but important document: the causa mortis (succession) document of my paternal grandfather who deceased on 7th March 2000 AD, with the document being compiled on the 5th of June 2000AD which lists my father and his surviving four siblings as their heirs. This document is important as it summarises the inheritance through my grandfather and thus provides documentation to explain how this inheritance came about. Of interest is the field known as tal-Katina, l/o Qrendi.
The document explains how Antonio, my late grandfather, owned 5/24 of this field which approximates to 20.8 % of the field, which has an area of 17,840 metres squared (so roughly, 3716.667 metres squared). It is also explained that this field, in its totality, is rented to third parties for Lm4 (EUR9.32) per year.
The document then explains how this came to be owned by Antonio: On the 23rd of June 1963 he bought one half of five sixths (1/2 of 5/6 == 5/12) whilst he was married to his wife Nicholina nee Borg. Then he subsequently redeemed from the parish church of Zurrieq the perpetual due of holy mass to the worth of 8 shillings on the 1st of November 1964.
Ok, hold it.
How did Antonio own 5/24 when he had bought 5/12? Why half? Is it because the other half belongs to his wife? I think not, as the description before this statement states that at the time of his death, Antonio owned the following which belong to the communcal acquisitions existing between him and his late wife. So the ownership of the 5/24 includes that of his wife.
So a look at the original document wherein the purchase was made beckons...
