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 in West Virginia specifically, leaving even a small asset unfunded can trigger a commission on the entire 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. Transfers to one's own revocable trust are generally exempt from West Virginia's real-estate excise tax, so cost isn't the reason people skip it — it's simply forgotten.
2. The mistake that costs more here than elsewhere
Left undone, that unrecorded property remains a probate asset, requiring a personal representative to be appointed. Under W. Va. Code § 44-4-12a(b), that representative is entitled to an additional 1% commission — not just on the small leftover asset, but on all property that isn't subject to administration and is includable for computing the federal estate tax. That includes the rest of the trust. A single forgotten asset can end up putting a commission on a trust corpus that was otherwise properly funded.
3. 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.
4. Treating the Small Estate Act as a safety net
West Virginia's Small Estate Act — $50,000 or less in personal property, or $100,000 or less in real property — is a genuine shortcut for modest, unfunded assets. It is not a backstop for a house or a sizeable account left outside the trust by mistake; those amounts still require a personal representative, with the associated commission rules.
