How are oaths divided if some heirs are women who are barred from swearing?

Primary text

If some of those involved are women, who are entirely barred from the Qasamah, their status is disregarded. If the heirs consist of a son and a daughter, the son swears the entire fifty oaths. If the heirs consist of a full brother and a uterine sister, and a consanguine brother and a uterine sister, the oaths are divided between the two full brothers: three oaths for the uterine brother and eight for the other, totaling eleven. The remainder is then rounded up, resulting in the consanguine brother swearing thirty-seven oaths and the uterine brother swearing fourteen oaths.
