Due-on-Sale Clause
Also called alienation clause, acceleration on transfer
Quick answer
A due-on-sale clause lets the lender demand full repayment if the property is transferred without consent. Federal law makes these clauses enforceable — but it also carves out a specific list of transfers a lender cannot accelerate on, which is where most legitimate estate and family planning happens.
Key facts
- Governing law
- Garn-St Germain Depository Institutions Act, 12 U.S.C. §1701j-3
- Protected transfers
- Includes transfer on death to a joint tenant or relative, transfer to a spouse or children, transfer incident to divorce, and transfer into a living trust where the borrower remains a beneficiary and occupancy does not change
- Scope of the protections
- The statutory exceptions apply to residential property of fewer than five dwelling units
- What it is not
- Not a due-on-encumbrance clause — placing a junior lien is treated separately
- Practical risk
- Acceleration is a lender option, not an automatic event; the exposure is real but discretionary
What it means
This clause has been standard in nearly all conventional loans since the Garn-St. Germain Depository Institutions Act of 1982, triggered by a sale or transfer of the property, though the Act carves out specific exceptions such as a transfer to a spouse or into certain living trusts.
Sellers structuring a subject-to or wraparound sale in California are relying on the existing lender not exercising this clause. Enforcement is inconsistent in practice, but it's a real, disclosed risk to the arrangement — not a loophole that has been closed or resolved.
Anyone considering a subject-to, wraparound, or informal assumption should understand this is precisely what's being risked, and should have the arrangement reviewed by a real estate attorney rather than relying on a template found online.
Why this matters when you are selling
This clause is the reason subject-to purchases, wraparound notes, and informal 'take over my payments' arrangements carry risk. In each of those the loan stays in the seller's name while the property changes hands, and the lender retains the contractual right to call the entire balance due. Whether a lender exercises that right is a business judgment — historically uncommon on a performing loan, and materially more attractive to the lender when the note's rate is far below the current market. Anyone structuring around this in a high-rate environment is taking a bet against the lender's incentive, and should say so plainly rather than describe the clause as theoretical.
The other half of the story matters more to ordinary families. Garn-St Germain protects the transfers people actually need: a house passing to a surviving joint tenant, a transfer to a spouse or children, a transfer required by a divorce decree, and the transfer of a residence into a revocable living trust where the borrower remains a beneficiary. These do not trigger acceleration, which is why moving a home into a trust for probate avoidance does not jeopardize the mortgage.
Common mistakes
Treating due-on-sale as an empty threat because 'lenders never call loans.'
Instead: It is discretionary, not unenforceable. A below-market note is exactly the asset a servicer has a reason to accelerate. Price the risk instead of dismissing it.
Avoiding a living trust out of fear of the clause.
Instead: Transfer of a residence into a revocable trust where the borrower remains a beneficiary is within the federal exceptions. The estate-planning benefit is available without triggering acceleration.
Assuming a deed transfer is invisible to the lender.
Instead: Deeds are public records and both servicers and insurers monitor them. Insurance changes are frequently what surfaces the transfer.
Questions people ask
Can I put my house in a living trust without triggering the due-on-sale clause?
Generally yes for a residential property of fewer than five units, where the borrower remains a beneficiary of the trust and the transfer does not change occupancy rights. This is one of the explicit exceptions in Garn-St Germain and it is the reason routine estate planning does not endanger the loan.
Does adding a child to title trigger it?
A transfer to a child is among the protected categories for residential property under the federal exceptions, but the details matter — including how title is taken and what happens to occupancy — and there are property tax consequences under Proposition 19 that are entirely separate from the loan question. Confirm both with counsel and a CPA before recording anything.
What actually happens if a lender enforces it?
The servicer demands payment of the full balance within a stated period. If it is not paid, the loan is in default and the nonjudicial foreclosure process becomes available. The practical cure is refinancing or selling — which is why an accelerated loan on a subject-to deal usually forces the outcome the parties were trying to avoid.
Bottom line
The due-on-sale clause is enforceable and discretionary at the same time, which is exactly what makes it dangerous to plan around casually. Ordinary family and estate transfers are protected by federal statute. Structures that leave a below-market loan in a seller's name while someone else takes the property are not protected, and in a high-rate environment the lender's incentive to act is at its strongest.
