Final answer:
Transmutation between spouses typically requires a written document that expresses the intent to change the property's character, except for gifts of personal items of small value that might not require writing, depending on the jurisdiction.
Step-by-step explanation:
The conditions that must be met for transmutation, where writing is not required for gifts between spouses, vary depending on jurisdiction. Generally, transmutation refers to a change in the legal character or ownership of property, such as from separate property to community property or vice versa. When it comes to gifts between spouses, most days this can be done verbally or with a physical act of giving, with the exception being when the gift is real property, necessitating a written document. However, there could be additional conditions or formalities required by specific state laws. For example, California law generally requires a written document expressing the intent to change the property's nature unless it falls under specific exceptions allowed by the Family Code, like gifts of personal items of relatively small value.
