Fla. Stat. § 736.08147

If a will or trust instrument granting income to the settlor’s or testator’s spouse for life is silent as to the time of distribution of income and the frequency of distributions, the trustee shall distribute all net income, as defined in chapter 738, to the spouse no less frequently than annually. This provision shall apply to any trust established before, on, or after July 1, 2007, unless the trust instrument expressly directs or permits net income to be distributed less frequently than annually.
