Community property is a statutory estate in Texas. All property acquired after marriage, whether purchased or earned, is jointly owned by the husband and wife. Income on separate property is considered community property. An increase in value of separate property is not community property. For example, if a spouse has a house worth $150,000 at the time of marriage and its value increases to $300,000, the increase is not community property. However, once community efforts, credit, or funds are used to increase the value or improve the property, community property rights accrue.
