David Mendez did everything right.
He and his wife Laura had lived in their Frisco home for sixteen years. Their kids were grown, they had retirement accounts, they had a modest investment portfolio, and they had — finally, after years of meaning to — signed a revocable living trust. Their estate planning attorney walked them through it: the trust would let their assets pass to their daughters without probate, it would keep management seamless if either of them became incapacitated, and it would protect against the court supervision that a will alone cannot avoid.
The next step was funding the trust — transferring their assets into it so the trust actually controlled what it was supposed to control. The retirement accounts would need beneficiary designation updates. The investment accounts were straightforward. And the Frisco house — the largest single asset they owned, worth considerably more than they paid for it in 2009 — needed to be deeded into the trust by recording a new deed with Collin County.
That was when David called his mortgage servicer.
He had a sensible question: would transferring the property to his living trust trigger the due-on-sale clause in his mortgage? Most mortgages contain this language — a provision allowing the lender to demand full repayment if the property is transferred or sold. David had no intention of selling. He intended to remain in the home, continue paying the mortgage, and keep everything exactly as it was — except that the title would now be held by his revocable trust with himself and Laura as co-trustees.
The customer service representative he reached, after forty-five minutes on hold, told him that any transfer of title would trigger the clause and the bank could call the loan. She was not reading from the law. She was reading from a script that was, on this specific point, incorrect.
David called his estate planning attorney. The answer he got was different — and it came with a citation.
The Federal Law That Protects This Transfer
The Garn-St. Germain Depository Institutions Act of 1982 is not a Texas statute. It is a federal law, enacted by Congress, that governs when a lender may — and may not — enforce a due-on-sale clause on a residential mortgage. And it specifically addresses the scenario David was asking about.
Under 12 U.S.C. § 1701j-3(d)(6), a lender may not exercise a due-on-sale option 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 that carefully. Congress wrote this exemption specifically for what David and Laura were doing: transferring their home into a living trust — an inter vivos trust — where they would remain as beneficiaries and where no one's right to live in the property was changing. The transfer does not trigger the due-on-sale clause. It cannot. The lender is prohibited by federal law from exercising that option.
This exemption applies to residential real property loans secured by liens on properties with fewer than five dwelling units — which covers the overwhelming majority of Texas homesteads. It applies regardless of the lender's internal policies, regardless of what the mortgage document says, and regardless of what a customer service representative says over the phone. Federal law preempts conflicting loan terms and state regulations on this point.
The customer service representative who told David otherwise was not being dishonest. She was telling him what her training script said about generic property transfers — and nobody had flagged for her that Congress carved out an explicit exception for living trusts in 1982. That knowledge gap is common, and it has real consequences. Families who take the representative's answer at face value often leave their trust unfunded. And an unfunded trust is, functionally, no trust at all.
Why the Unfunded Trust Problem Matters in Texas
A revocable living trust only controls what is titled in its name. The document itself — however well-drafted — cannot reach assets the trust does not own. This is what estate planning attorneys call the unfunded trust problem, and it is one of the most common reasons Texas families end up in probate despite having signed a trust.
If David and Laura never transferred their Frisco home into the trust — because they were afraid of triggering the due-on-sale clause — then when one of them dies, the house would not pass through the trust. It would pass through their estate. If there is a will, the home would go through Collin County probate. If there is not, intestate succession rules would govern. Either way, their daughters would face a court proceeding, attorney fees, and months of delay — exactly what the trust was designed to prevent.
The house is almost always the largest asset a Texas family owns and the one most likely to be left out of the trust. Clients who confidently fund their bank accounts, investment portfolios, and business interests sometimes freeze at the home because of the mortgage. And because many mortgage servicers' customer service lines are not equipped to distinguish between a due-on-sale-triggering sale and a Garn-St. Germain-protected trust transfer, the freeze often persists.
An estate planning attorney who understands this will walk you through exactly what to say to your lender — and what documentation to send if the lender pushes back.
The Two Conditions for Protection
The Garn-St. Germain exemption has two requirements that must both be satisfied:
First, the trust must be an inter vivos trust in which the borrower is and remains a beneficiary. A revocable living trust where you are both the settlor and the initial trustee — the standard structure used in Texas estate planning — satisfies this automatically. You create the trust during your lifetime (inter vivos means "during life"), and you remain as the primary beneficiary with full rights to use and enjoy the trust property. The structure that caused David to call his lender in the first place is the structure Congress specifically protected.
Second, the transfer must not relate to a transfer of rights of occupancy. David and Laura are not transferring their right to live in the house. They are transferring bare legal title to a trust entity that they control. They will continue living there, paying the mortgage, maintaining the property, and exercising every right they have ever had as homeowners. Nothing changes from a practical standpoint except whose name appears on the Collin County property records and who would manage the asset if one of them became incapacitated.
If both conditions are met — and they almost always are in a standard Texas living trust structure — the lender has no right to call the loan.

12 steps every Texas family should take to protect their legacy
Knowing the law protects you does not automatically make your lender's processing department aware of it. In practice, transferring a Texas home into a living trust involves several steps, and handling them correctly from the start prevents headaches later.
The deed itself. A new deed must be recorded in the county where the property is located — in David and Laura's case, the Collin County Clerk's office. The deed transfers title from David and Laura Mendez, as individuals, to "David Mendez and Laura Mendez, as co-trustees of the Mendez Family Revocable Living Trust." The deed must comply with Texas recording requirements and should be drafted by an estate planning attorney familiar with Texas property law.
Notifying the lender — not required, but advisable. No Texas or federal law requires you to notify your mortgage servicer before making this transfer. The Garn-St. Germain Act's protection is not contingent on advance notice. But many Texas estate planning attorneys recommend sending the servicer a copy of your trust certificate — a shortened document confirming the trust's existence and the trustees' authority — along with a brief written notice of the transfer. This creates a paper trail and reduces the chance of a servicer claiming later that it was unaware of the transfer. If the servicer raises an objection, you or your attorney can respond with the Garn-St. Germain citation. Most servicers, when presented with the federal statute, accept the transfer without further objection.
Title insurance. If you purchased title insurance when you bought your home, review your policy. Some title insurers issue policies to named individuals and may require a simple endorsement when ownership changes to a trust. This is typically straightforward and inexpensive, and your estate planning attorney can advise whether your specific policy requires it. The goal is to ensure that the trust is properly insured against title defects going forward.
The homestead exemption — do not miss this step. Texas's homestead exemption under Tex. Tax Code § 11.13 provides significant property tax savings to owner-occupied residences. When you transfer your home to a trust, Collin County (or your home county) will see a new owner in its records — the trust — and may remove the homestead exemption automatically. You will need to refile with the county appraisal district to confirm that the trust qualifies. The trust document must contain specific language allowing the trustee to claim homestead rights on behalf of the beneficiaries who occupy the property. An estate planning attorney drafting the trust for Texas will include this language; a form trust downloaded from the internet may not. WG Law has a detailed guide on this specific issue in our post on the tax break Texas homeowners nearly lose when transferring their home to a trust.
Investment and second properties — a different analysis. The Garn-St. Germain exemption covers residential real property with fewer than five units. If you own rental property or a second home and want to transfer it into your trust, the federal protection still applies to residential structures. However, commercial loans and some investment-property loans are governed by different frameworks, and your loan documents may contain provisions beyond what the federal residential-mortgage statute addresses. Have your attorney review the specific loan documents before transferring commercial or investment property into a trust.
The Circle Closes: What Happened to David and Laura
After speaking with their estate planning attorney, David and Laura recorded the deed transferring their Frisco home to the Mendez Family Revocable Living Trust. Their attorney drafted a short letter to the mortgage servicer, enclosed a copy of the trust certificate and a citation to 12 U.S.C. § 1701j-3(d)(6), and noted that the transfer fell within the statutory exemption from the due-on-sale clause. The servicer updated its records without objection.
David refiled for the homestead exemption with Collin County. The exemption was reinstated within six weeks. Their property tax bill continued unchanged.
Two years after the trust was funded, Laura was diagnosed with an autoimmune condition requiring surgery and a six-week recovery. Because the trust owned the home and David was named as successor trustee for the period of incapacity, he could manage all trust assets — including the property — without any court proceedings. There was no need for a guardianship, no emergency court appearances, no break in David's ability to manage their financial life while Laura recovered.
That is what the trust was designed to do. And it could only do it because the trust was funded.
The Real Risk Is Leaving the Trust Unfunded
The due-on-sale clause is not the danger in a standard Texas living-trust transfer. The danger is being misinformed about the due-on-sale clause and leaving the trust unfunded as a result.
A family that sets up a living trust but never transfers their home into it has spent money on a document that will fail at the moment it was supposed to work. Their estate plan will route the house — their largest asset — through probate anyway. Their daughters will deal with the process the trust was supposed to eliminate. And the opportunity to prevent that outcome was lost not to legal complexity, but to a customer service script that omitted one federal statute.
Texas living trusts, when properly funded and properly drafted, are among the most effective estate-planning tools available to Texas families. The funding step — the part where assets are actually titled into the trust — is where many plans succeed or fail. For a home with a mortgage, that step requires knowing what the law actually says.
