Some of the estate planning strategies in this website depend on the ownership of assets. Alaska, Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, Washington and Wisconsin have community property systems. (Alaska’s is elective.) Under such a system, each spouse usually has a one-half interest in property acquired during marriage. If you live in a community property state, bear this in mind as you read over the different sections on estate planning as to how the information relates to your situation.
