Quick answer: the most common mistake is never recording a new deed into the trust's name for real estate. It's still the family's own responsibility, and skipping it means that property goes through full Kentucky probate regardless of the trust.

Signing ≠ funding
1. Real estate deed never recorded — the #1 mistake
Moving real estate into a trust requires a new deed, signed and recorded with the county clerk, naming the trust as owner. This is the step most often skipped. Left undone, that property remains a probate asset — subject to the executor fee and Kentucky's 6-month creditor claim period, which under KRS 396.011 doesn't even start until a personal representative is appointed to deal with it.
2. Financial accounts left titled individually
Bank and brokerage accounts don't join a trust automatically. Each one has to be retitled into the trust's name, or the institution needs a copy of the trust document plus a change-of-ownership form. Accounts opened after the trust was created are especially easy to forget.
3. Assets acquired after the trust was created
A trust only holds what's actually been transferred into it. A car, account, or property acquired afterward stays outside the trust unless someone deliberately adds it — which is why periodic review matters as much as the initial funding.
4. Treating dispensing with administration as a safety net
Kentucky's Petition to Dispense with Administration — personal property of $30,000 or less with a surviving spouse or children, or any size with no will, no debts, and unanimous heir agreement — is a genuine shortcut for modest or agreeable estates. It is not a backstop for a house left outside the trust by mistake in an estate that doesn't meet those specific conditions; that property requires full standard probate regardless of the unused trust document.
