What distinguishes a separate property regime from community property?

A separate property regime allows each spouse to maintain individual ownership and control over their assets, distinguishing it from community property, where assets acquired during the marriage are jointly owned by both spouses. In a separate property system, individuals can own property independently, meaning that any assets they bring into the marriage or acquire individually during the marriage remain their personal property.

This framework emphasizes individual rights and autonomy when it comes to property ownership, which is critical in marital agreements and discussions regarding asset division during divorce. It contrasts with community property systems, where there is typically a presumption that all property acquired during the marriage is jointly owned, regardless of which spouse purchased it.

The other options don't accurately reflect the nature of a separate property regime. Joint ownership of assets during marriage and mandatory registration in joint names do not pertain to separate property, and the idea that only one spouse can inherit property contradicts the fundamental principles of asset rights in marriage. Thus, individual ownership and control represented in option B are key characteristics that correctly define a separate property regime.
