A.  A spouse’s undivided interest in property otherwise classified as separate property under Article 2341 remains his separate property regardless of the acquisition of other undivided interests in the property during the existence of the legal regime, the source of improvements thereto, or by whom the property was managed, used, or enjoyed.

B.  In property in which an undivided interest is held as community property and an undivided interest is held as separate property, each spouse owns a present undivided one-half interest in that portion of the undivided interest which is community and a spouse owns a present undivided interest in that portion of the undivided interest which is separate.
