Yevamos 11:7

Continuing the case of a woman who remarried too quickly, so she doesn’t know which husband fathered her child: If one husband was a kohein and one was a Yisroel, the child must marry a woman who is fit to marry a kohein; he may not become impure for a corpse, but if he does, he does not receive lashes. He may not eat terumah but if he does, he need not repay it and pay an extra fifth; he does not receive a share from the threshing floor; he may sell terumah to kohanim and keep the money; he does not receive sanctified items from the Temple; he doesn’t offer sacrifices; he may give his own offerings to any kohein he chooses; he need not give the portions of shoulder, cheeks and abomasum; his first-born animals graze until they develop a blemish; he must follow the stringencies of both a kohein and a Yisroel. If both husbands were kohanim, the son acts as an onen (bereaved) if they die (i.e., refraining from performing the Temple service, etc.) and they act as an onen for him if he dies. He may not become ritually unclean for them, nor they for him. He doesn’t inherit from them but they do inherit from him. He is exempt from penalty if he strikes or curses one of them. He works each family’s duty shift but he does not receive a portion of the sacrifices from those shifts (because he might not be entitled to it). If both families work the same shift, he takes a portion.

Yevamos 12:1

Performing chalitzah requires a panel of three judges but they can be three lay people. Chalitzah is valid when performed with a shoe but not with a cloth slipper; it is valid when performed with a sandal that has a heel but not when performed with a sandal without a heel; it is valid when performed with a shoe that has straps below the knee but not when performed with a shoe that has straps above the knee.
