Acceleration Clause
A provision in a promissory note, deed of trust, or credit agreement that allows the lender, upon the occurrence of a specified event of default, to declare the entire outstanding balance immediately due and payable. In Texas, acceleration of a real-property-secured loan generally requires both notice of intent to accelerate and notice of acceleration, and is subject to a four-year statute of limitations on subsequent enforcement.
An acceleration clause is a provision in a promissory note, deed of trust, or credit agreement that allows the lender, upon the occurrence of a specified event of default, to declare the entire outstanding loan balance immediately due and payable, bypassing the original installment schedule. Without an acceleration clause, a lender's only remedy for a missed installment would be to sue for that installment as it comes due, an inefficient mechanism that effectively forces the lender to wait through maturity. Acceleration is the gateway to most lender remedies, including foreclosure on collateral.
Two-step Texas notice rule
Texas common law has long required two separate notices to accelerate a debt secured by real property: (1) notice of intent to accelerate, informing the borrower that default exists and that acceleration will occur if the default is not cured by a specified date; and (2) notice of acceleration, declaring that acceleration has occurred and the entire balance is due. Holy Cross Church of God in Christ v. Wolf (Tex. 2001) restated that both notices are required and that each must be clear and unequivocal. Most modern deeds of trust include language addressing the two-step requirement either by waiver or by specification of the notice mechanism.
Statutory residential notice
For real property used as the debtor's residence, Section 51.002(d) of the Property Code adds a statutory 20-day cure period: the mortgage servicer must serve a notice of default with at least 20 days to cure before serving a notice of sale. The 20-day notice applies notwithstanding any agreement to the contrary and operates alongside the common-law notices of intent to accelerate and of acceleration. Federal Real Estate Settlement Procedures Act (RESPA) regulations may add further pre-foreclosure obligations on residential mortgage servicers.
Statute of limitations interaction
Section 16.035 imposes a four-year statute of limitations on foreclosure of a real property lien. Where a loan has an acceleration clause, the limitations period generally begins running on the date of acceleration (rather than the original maturity date). This creates a practical trap: an acceleration triggered too early, before the lender is ready to enforce, can start the clock prematurely and result in a barred claim. A lender may abandon a prior acceleration, and Section 16.038 lets the lienholder or servicer rescind or waive acceleration by written notice served on each obligor before limitations expires. The note is then treated as if it had never been accelerated.
Events triggering acceleration
Standard acceleration triggers include: (1) failure to pay principal or interest when due; (2) breach of any covenant after notice and cure period; (3) bankruptcy or insolvency of borrower or guarantor; (4) material misrepresentation in loan documents; (5) sale or transfer of collateral without consent ("due-on-sale" clauses); (6) cross-default on other indebtedness; (7) death or dissolution of guarantor; (8) material adverse change in financial condition.
Rescission and reinstatement
An acceleration may be rescinded by mutual agreement of the parties or, in some cases, by unilateral lender action under specific contractual rescission rights. Many deeds of trust grant the borrower a right to reinstate after acceleration but before foreclosure sale by paying all delinquent amounts plus costs. Rescission and reinstatement both restore the loan to its pre-acceleration installment schedule and reset the limitations clock.
For Texas lenders, acceleration is a powerful but procedurally exacting remedy. Disputes tend to turn on whether contractual notices were served in proper form and statutory notices, such as the residential 20-day notice, were given. Proof of service matters too, and a Section 51.002 notice sent by certified mail is served when it is deposited in the mail. The other recurring questions are when the four-year limitations period began to run and whether a prior acceleration was rescinded or abandoned. For Texas borrowers facing acceleration, the most common defenses involve insufficient notice, improper notice content, or waiver or abandonment of acceleration through the lender's prior conduct (accepting payments without insisting on strict performance).
