| Default ownership during marriage | All wages + acquisitions = community property (50/50) | Each spouse's earnings are their own; jointly titled property is shared |
| What 'separate property' means | Property owned before marriage, plus gifts and inheritances received during marriage | Property titled in one spouse's name acquired before or during marriage (subject to commingling rules) |
| Default split at divorce | 50/50 of community property; separate property keeps to its owner | Judge divides marital property equitably (often but not always 50/50) |
| Default split at death (intestate) | Surviving spouse keeps their community half; deceased spouse's half passes by intestacy | Surviving spouse claims elective share (~1/3 to 1/2) of decedent's estate |
| Islamic compliance challenge | Conflict with separation-of-property principle is automatic and immediate | Conflict surfaces mostly at divorce / death; daily ownership is closer to Islamic norms |
