Real property: a new deed, recorded. The owner signs a deed conveying the property from themselves individually to themselves as trustee of the named trust, and the deed is recorded with the county. Three practical points travel with it. The title insurance policy and the homeowner's policy should be reviewed, because both name an insured. Some states charge a recording fee or a transfer tax and many exempt a transfer to a revocable trust from the latter, which is a question for the county. And in a state with a homestead exemption or a property-tax cap tied to ownership, whether the transfer disturbs it is a state-specific question that should be answered before the deed is signed, not after.
The mortgage question has a clean federal answer, and it is the single most useful fact on this page. Borrowers hesitate to deed a mortgaged house into a trust because loan documents contain a due-on-sale clause. The Garn-St Germain Depository Institutions Act settles it. Under 12 U.S.C. 1701j-3(d), "with respect to a real property loan secured by a lien on residential real property containing less than five dwelling units", a lender "may not exercise its option pursuant to a due-on-sale clause upon ... a transfer into an inter vivos trust in which the borrower is and remains a beneficiary and which does not relate to a transfer of rights of occupancy in the property."
Read the two limits precisely, because both do work. The property must contain fewer than five dwelling units, so a larger apartment building is outside the protection. And the borrower must be and remain a beneficiary of the trust, which covers the ordinary revocable living trust and does not plainly reach an irrevocable trust the borrower does not benefit from. Note also that the statute stops the lender calling the loan; it does not change who owes the debt, and it does not relieve anyone of telling their insurer.
Bank and brokerage accounts: change the registration. The account is re-registered in the name of the trustee, and at many institutions the internal mechanic is opening a new account and moving the assets, which means new account numbers, new automatic payments and new direct deposits. Expect to produce a certification of trust rather than the whole instrument. A brokerage transfer of this kind is a change of registration, not a sale, so it does not ordinarily realize gain, but confirming that with the custodian before the transfer is cheap.
Retirement accounts must not be retitled, and the bar is structural rather than punitive. Internal Revenue Code section 408(a) defines an individual retirement account as a trust created for the exclusive benefit of an individual or their beneficiaries, so another trust cannot occupy the owner's place; the account cannot be transferred, not merely taxed if it is. Attempting it means taking the money out, which is a distribution with the tax and, under age 59½, the penalty that follows. Employer plan accounts stay in the participant's name for the same kind of reason. What is available, and entirely different, is naming the trust as the beneficiary of the account. That is permitted, sometimes the right answer, and governed by its own rules about which trusts a plan may look through, so it is a decision to take advice on rather than a funding step.
Life insurance and annuities are not funded by retitling either, and the reason is worth separating from the retirement-account rule. A policy's death benefit goes to whoever is named on the beneficiary form, whoever owns the policy, so the routine question for a living trust is whether the trust should be the named beneficiary rather than whether the policy should be moved. Changing the owner of a policy to a trust is a different and deliberate act with transfer-tax consequences and a three-year clock attached, which is the irrevocable life insurance trust decision and not part of ordinary funding.
Business interests, vehicles and everything else. An interest in an LLC, partnership or closely held corporation is usually governed by an operating agreement, partnership agreement or shareholders' agreement that restricts transfers, so the document has to be read and consents obtained before any assignment is signed; the transfer itself is then an assignment plus an amendment to the entity's records. Vehicles and boats are retitled through the state motor-vehicle or licensing authority, and some owners deliberately leave a car out for liability reasons. Tangible personal property with no title document moves by a general assignment of personal property signed alongside the trust. And an interest that has not yet arrived, such as an inheritance the client expects, cannot be funded in advance.
Funding does not end. A new savings account, a refinance that requires the house to come out of the trust temporarily, an inherited brokerage account, a business started three years later: each begins in the individual's own name. This is why a pour-over will exists and why it is a backstop rather than a solution, since everything it catches goes through probate on the way in. A short annual review of what is titled where is the only reliable answer.
