## Holding
A transmutation writing must expressly show on its face that the property’s character or ownership is being changed; extrinsic evidence cannot supply the missing express declaration. The wife’s consent to another beneficiary for retirement accounts did not itself surrender her community ownership interest.
> [!note] Scope and later law
> No special terminology is indispensable, but the written expression must actually communicate the required change. Distinguish beneficiary consent from transfer of ownership.
