Quick answer: the single most common mistake is signing the trust but never retitling assets into it — especially real estate. An unfunded trust leaves the estate in full Florida probate. See what that would cost in the Florida probate vs living trust calculator.
1. Real estate never deeded into the trust
Florida real estate requires a new deed transferring the property from the individual owner's name into the trust's name, and that deed must be properly recorded with the county. A trust document alone, however carefully drafted, does not move title on its own — this is consistently the single biggest funding gap.
2. Homestead property titled incorrectly
3. Financial accounts left titled individually
Bank and brokerage accounts need to be either retitled into the trust's name or given trust beneficiary designations. Accounts left in an individual's name pass outside the trust and typically land back in the probate estate.
4. Assets acquired after the trust was created
A trust only covers what's actually transferred into it. A new account, vehicle, or newly purchased property acquired after the trust was signed needs its own separate transfer — the trust doesn't automatically absorb future acquisitions.
5. Assuming summary administration is a safety net
If unfunded assets are non-exempt personal property or real estate under $150,000 in value, summary administration is available — but that's a consolation for a funding mistake, not the intended outcome of setting up a trust. Larger unfunded assets go through full formal administration, fee schedules and mandatory creditor period included.
