Yes, the Inheritance Act of 1965 gives common-law partners or cohabitees who meet certain preconditions equal rights to those of married spouses. If the common-law partners or cohabitees  were living together in a joint household, at the time the deceased died, and neither of them was married to someone else when one of them dies, then the one who survives is to receive the share he/she would have received if they had been married to one another.
