Canadian billionaire Father cohabits with much younger immigrant woman, Mother, for 10 years.

They have three children together.

They are not married.

Father pays $35,000 Canadian per month in child support.

Mother wants more.

Challenging Quebec province and other Canadian law that denies property division and alimony to common law partners or mere cohabitants, Mother sues for both.

Florida law also generally precludes a cohabitant from claiming an interest in the other partner’s property or seeking alimony or support other than for children in common.

This case has generated a lot of media attention in Canada.
