Before a lender can foreclose, it must typically accelerate the loan — declaring the entire balance due. A defective or missing Notice to Accelerate can be a complete defense. Learn acceleration requirements, breach letters, and how to challenge improper acceleration.
Get Free Case ReviewAcceleration is the lender's act of declaring the entire unpaid principal balance of the loan immediately due and payable, rather than continuing to accept monthly installment payments. Under an installment promissory note, the borrower normally pays in monthly installments over the loan term (typically 30 years). When the borrower defaults, the lender may "accelerate" the note — calling the full balance due at once. Acceleration is a condition precedent to foreclosure in virtually every jurisdiction. Without proper acceleration, the lender cannot foreclose because no single missed payment justifies seizing the entire property — only the accelerated full balance does.
Why Acceleration Matters in Foreclosure Defense
If the lender failed to properly accelerate the loan before filing foreclosure, the foreclosure complaint is premature and subject to dismissal. If acceleration never occurred, the statute of limitations may continue running on each missed installment — limiting the lender's recovery and potentially barring foreclosure on older defaults.
Nearly every mortgage promissory note and deed of trust contains an acceleration clause. This contractual provision grants the lender the option (not the obligation) to accelerate the debt upon default. Standard language appears in Fannie Mae/Freddie Mac uniform instruments, typically paragraph 6 or 7 of the note and paragraph 22 of the mortgage/deed of trust. Key language: "If Borrower defaults by failing to pay... Lender may require immediate payment in full of the principal balance remaining due..." The word "may" is critical — acceleration is optional. The lender can choose to accelerate upon any default or can elect to accept late payments without accelerating. The acceleration clause also typically contains a cure provision allowing the borrower to reinstate before a certain deadline.
Most mortgages and deeds of trust require the lender to send a breach letter or Notice of Intent to Accelerate before accelerating the loan. Under the standard Fannie Mae/Freddie Mac mortgage (paragraph 22), the lender must: (1) give the borrower written notice specifying the default, (2) state the action required to cure the default, (3) provide a date by which the default must be cured (typically at least 30 days), (4) inform the borrower that failure to cure will result in acceleration and foreclosure, and (5) advise the borrower of the right to reinstate and to assert defenses in court. This notice is separate from any Notice of Default (NOD) or Notice of Sale. The breach letter is the first step — a contractual requirement that must be satisfied before the lender can accelerate.
| Document | Purpose | Required By | Timing |
|---|---|---|---|
| Breach Letter / Notice of Intent to Accelerate | Warns borrower of default and right to cure before acceleration | Mortgage contract (paragraph 22) | Before acceleration; typically 30+ days before |
| Notice of Default (NOD) | Formally records the default and begins non-judicial foreclosure timeline | State statute (non-judicial states) | After breach letter; before Notice of Sale |
| Notice of Sale (NOS) | Announces the foreclosure auction date | State statute | After NOD; before auction |
If the lender cannot produce the breach letter or proof of mailing, acceleration was ineffective. Demand production of the breach letter in discovery. Sometimes lenders cannot produce it — especially if the loan changed servicers.
The letter must strictly comply with contract requirements — correct default amount, correct cure deadline, correct borrower address. A letter with wrong amounts, insufficient cure time, or sent to wrong address is defective and may invalidate acceleration.
Only the note holder can accelerate. If a servicer accelerated without proper authority from the holder, or if the entity that sent the breach letter was not the holder, acceleration may be void. See: Standing to Foreclose.
Once the loan is accelerated, the statute of limitations begins running on the entire debt. If the foreclosure was filed after the SOL expired, it is time-barred. Some states also recognize "deceleration" — where the lender voluntarily abandons acceleration, restarting the SOL. See: SOL Guide.
