Could you please provide a reference for the highlighted quote above.
My understanding was that the Civil and Commercial Code only provided 50% for the spouse class in most cases (unless there are no other classes of heirs).
Section 1635. Surviving Spouse
The surviving spouse is entitled to the inheritance of the deceased in the class and according to the division as hereunder provided:
if there is an heir according to Section 1629 (1) surviving or having representatives as the case may be, such surviving spouse is entitled to the same share as an heir in the degree of children;
if there is an heir according to Section 1629 (3) and such heir is surviving or has representatives, or if in default of an heir according to Section 1629 (1), there is an heir according to Section 1629 (2) as the case may be, such surviving spouse is entitled to one half of the inheritance;
if there is an heir according to Section 1629 (4) or (6) and such heir is surviving or has representatives, or if there is an heir according to Section 1629 (5) as the case may be, such surviving spouse is entitled to two-thirds of the inheritance;
if there is no heir as specified in Section 1629, such surviving spouse is entitled to the whole inheritance.
