Texas is a community property state much like most of the rest of the southwest. That means that technically it is also a separate property state. All assets that are brought in to the marriage are separate property assets which means that if there is a divorce then those assets are the individual who brought them into the marriage. To the extent that those assets appreciate then the appreciated portion would then become community property.
Property that is received by inheritance after the marriage is an exception to the rule that all property acquired after the date of the marriage is community property. Inherited property, regardless of when it is inherited before or after the divorce remains separate property.
