Quick answer: the most common mistake is never recording a new deed into the trust's name for real estate. North Dakota adds a second, easy-to-miss version: forgetting mineral, oil, or gas interests, which need the same treatment.

Signing ≠ funding
1. Real estate deed never recorded — the #1 mistake
Moving real estate into a trust requires a new deed, signed and recorded, naming the trust as owner. This is the step most often skipped. Left undone, that property remains a probate asset — subject to the full District Court process, regardless of the trust document sitting in a drawer.
2. Mineral, oil, and gas interests left unfunded — North Dakota's own risk
Mineral, oil, and gas interests are classified as real property and need their own conveyance into the trust's name, separate from the trust document itself and separate from any surface-land deed. A family that funds the house but forgets the mineral interest underneath it leaves that interest exposed to probate.
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 affidavit as a safety net
North Dakota's small estate affidavit — $100,000 or less in personal property, net of liens — is a genuine shortcut for modest, unfunded assets. It's not a backstop for a house, a mineral interest, or a sizeable account left outside the trust by mistake; those require full probate.
