How Do You Clear a Collateral File Exception Before It Kills a Trade?

You clear a collateral file exception by delivering the document the agency’s custodial rulebook requires, in the form that rulebook requires, before the certification deadline runs. Each of the three rulebooks read here names its own narrow substitutes. Ginnie Mae accepts a clarification for a defect it does not treat as material. Freddie Mac certifies on a seller’s affidavit where a recorder’s office does not record assignments, and on a certified copy while the original sits at the recorder’s office. Fannie Mae’s Requirements for Document Custodians allow certification of an intervening endorsement with a missing name or title in some cases. Those substitutes, and the lost-note instruments the sections below walk through, are the rulebooks’ own terms. Freddie Mac’s handbook tells the custodian: “You must not certify a Mortgage for which you have identified data or document discrepancies until all exceptions have been corrected.” Ginnie Mae’s manual puts the cure on the issuer: “It is the Issuer’s responsibility to correct or resolve defects, or to provide the document custodian with adequate clarification for those defects that are not considered material.” Fannie Mae’s custodian, on finding an error, “must notify the Seller immediately” and work with the seller to resolve it. A side letter, an indemnity, or a promise to deliver later appears in none of those provisions as a cure. In our view, where the document is gone for good, the deadlines in the rulebooks run whether the exception clears or not, and the trade has to answer for that before settlement.

This article reads the custody rulebooks of all three agencies. For Fannie Mae they are Selling Guide topics A3-3-04, A3-3-05, and E-2-01 (each dated May 4, 2022) and the Requirements for Document Custodians (Version 15.0, August 2025, which we call the RDC). They also include the Document Custodian Certification Job Aids the RDC incorporates (Version 4.0, August 2025). For Freddie Mac they are Guide Sections 6301.4, 8107.1, and 3602.2 and the Document Custody Procedures Handbook (February 2026). For Ginnie Mae they are Mortgage-Backed Securities (MBS) Guide Chapters 11 and 13 and Chapters 3 and 7 of the Document Custody Manual (Appendix V-01 to the MBS Guide). On the allonge and lost-note questions the article reads the uniform text of Uniform Commercial Code (UCC) Sections 3-204 and 3-309 and the enactments of Delaware, Ohio, Minnesota, and New York. We read each of them whole. The agencies’ eNote custody rules, Fannie Mae’s repurchase topics, and Freddie Mac’s Section 6301.2 on note endorsement were not read for this article and are not covered here.

What is a collateral file exception, and who raises it?

A collateral file exception is the custodian’s finding that a required document is missing, nonconforming, or mismatched to the loan data, and the custodian raises it because it cannot certify until the exception is cured. Fannie Mae defines the documents in question: “Custodial documents are the legal mortgage documents an approved document custodian takes into physical custody when Fannie Mae purchases or securitizes a loan.” Its Selling Guide adds that “The document custodian is acting on behalf of the seller/servicer and Fannie Mae when certifying loan documents and data at the time of acquisition by Fannie Mae.” Under the RDC, when the custodian finds that a Required Document “is missing, is inconsistent with Fannie Mae’s requirements, or is inconsistent with the Loan Data that was transmitted to Fannie Mae, it must notify the Seller immediately,” and if it “discovers errors as part of the certification process prior to Fannie Mae’s purchase of the Mortgage Loans, the Document Custodian must work with the Seller to resolve the issues.”

Freddie Mac’s Guide makes the exception a condition precedent to funding in terms. Under Section 6301.4(a), “Settlement cannot occur until delivery is complete,” and delivery is complete only when, among other things, “The Notes and all other required documentation are delivered to and certified by the Document Custodian.” The handbook then bars the certification while an exception is open, in the sentence quoted above, and Section 6301.4(a)(i) gives the consequence: if the seller does not complete a Guarantor or MultiLender Swap delivery “by 8:00 PM Eastern Time on the day immediately preceding the scheduled Settlement Date, Freddie Mac has the right, in its sole discretion, to cancel or postpone the settlement or funding until delivery has been completed,” and the seller indemnifies Freddie Mac for the cancelation or postponement.

Ginnie Mae runs the same gate at the pool level. Its custodian must “Notify the Issuer of any documents received that require correction or completion before certification can be made,” and an issuer must obtain an initial certification for every single-family pool type “before issuing the related security,” by which the custodian certifies that it has received “the minimum loan, pool, or loan package documents required to allow a Ginnie Mae security to be issued.” The issuer’s duty is stated in the manual and again in MBS Guide Chapter 11, which puts it this way: “Issuers are responsible for correcting or resolving any defects found during the certification process.”

None of this bears on whether the borrower owes the debt, and nothing in the rulebooks read here says it does. The exception is a question about whether the custodian can certify and the buyer can fund. In our view it is a question for pre-bid diligence, not for the credit file. In our view it sits apart from any compliance representation the seller gives in a master loan purchase agreement (MLPA) on the same loan.

Which exception categories cure before funding, and which do not?

An exception cures before funding when the document the rulebook requires can still be produced in the form it requires. An endorsement cures while the endorser exists, and an allonge cures when it is affixed. A missing assignment is a timing problem for two agencies and not a custodial document for the third. A lost note is the category that may not cure at all.

A defective or missing endorsement cures if the entity that must sign still exists. All three agencies require an unbroken chain. Fannie Mae’s custodial exhibit calls for the original note endorsed in blank and without recourse, with “no break in the chain of endorsements,” and the RDC requires every intervening endorsement to carry the prior noteholders’ signatures. Freddie Mac’s handbook tells the custodian what to do when a signature is missing: enter the discrepancy and wait for the seller, but “If the endorsing institution is no longer in business and the Seller cannot obtain the signature, do not certify the Note.” Ginnie Mae “requires that the chain of endorsements from the originator of the loan to the pooling Issuer of the note be complete.” That row has two conditions, an institution no longer in business and a signature the seller cannot obtain, and the same chapter addresses an endorser that has been renamed or succeeded: an endorsement may say that the endorser is the “successor in interest to” or “successor by merger to” the preceding endorser, and for a break “due to a name change, merger, acquisition, or other event not identified in the endorsement itself” the handbook requires the seller to provide documentation for the note file, “such as a letter or notice from the regulator, state corporation commission, or similar authority.” An originator that merged out of existence has a successor who can sign. One that dissolved without a successor does not, and neither of the other two rulebooks addresses that case.

An allonge cures where the jurisdiction allows one, and every rulebook read here says how it fails. Freddie Mac’s custodian may certify a note carrying an allonge only if “The allonge is permanently affixed to the Note (taping or pasting the allonge to the Note are not acceptable)” and it references the borrower’s name, the property address, and the original principal balance. Fannie Mae’s RDC requires that “The allonge must be permanently affixed to the related note and clearly identify the note by referencing at least the amount of the note, combined with either the name of the borrower(s), or the address of the security property.” Ginnie Mae’s manual allows allonges “as long as they are enforceable and meet the requirements of the jurisdiction in which the mortgaged property is located,” and the allonge “must be an original, must clearly reference the note, and must be firmly affixed to the note.” Affixation is the point of the exercise: under UCC Section 3-204(a), “For the purpose of determining whether a signature is made on an instrument, a paper affixed to the instrument is a part of the instrument.” Fannie Mae and Freddie Mac also permit facsimile endorsements on conditions: Fannie Mae “may permit facsimile endorsements of notes if the endorsing entity provides a corporate resolution authorizing facsimile signatures,” and Freddie Mac accepts a facsimile where the seller’s documents support it and the signature was applied in ink by a seller employee using a stamp, and it rejects endorsements generated by machine.

A missing intervening assignment is a timing problem for Freddie Mac and Ginnie Mae, and it is not a Required Document under the RDC’s general list for Fannie Mae. The RDC says the custodian “is required to hold only the following documents” and then lists them; security instruments that carry no promise to pay, “intervening assignments, title policies, insurance or guaranty certificates (except as outlined above), are not Required Documents.” Freddie Mac tolerates no gap: “There may be no gap in the assignment chain: assignments of the Security Instrument must begin with the original mortgagee and continue unbroken to: (i) the Seller, (ii) the current Servicer, if there is a Concurrent Transfer of Servicing, or (iii) MERS,” which Fannie Mae’s RDC expands as the Mortgage Electronic Registration System and Freddie Mac’s handbook names as the mortgagee of record on registered loans, and Freddie Mac does not accept an assignment to blank. The custodian holds the assignments with the note unless the mortgage is registered with MERS or the servicer has shown that it holds them. A servicer may elect to hold the assignments for MERS-registered mortgages and certify that chain itself. Four rows of the handbook’s assignment chart bar certification: two rows for assignments not delivered say “Do not certify until resolved,” a broken chain says “Do not certify until corrected,” and an assignment to blank says “You may not certify.” But an assignment sitting at the recorder’s office is not one of those rows. Guide Section 6301.4(a)(ii) provides that “If a recorder’s office has not yet returned a recorded Intervening Assignment to the Seller/Servicer, the Seller/Servicer must deliver a certified copy of the assignment sent for recordation to the Document Custodian,” and the handbook lets the custodian “certify the Note based on a Seller-certified copy of the assignment or related documentation.” Ginnie Mae allows the same accommodation at initial certification, where the issuer “may use a blanket certification which certifies that all intervening assignments for mortgages located in the same recording jurisdiction have been transmitted for recordation,” but the accommodation expires at final certification: “The assignments must have been recorded and the chain of assignments must be complete,” and “Copies of the intervening assignments are acceptable only if the originals have been lost and if they clearly show evidence of recordation.”

The recorded security instrument and the title policy are program-specific, and for two of the three agencies they are not on the custodial list. Fannie Mae’s delivery instruction is blunt: “Do not staple one document to another and do not include any mortgages, deeds of trust, title insurance policies, or appraisals.” The RDC makes the security instrument a Required Document “ONLY if the security instrument includes the promise to repay the principal amount borrowed and sets forth all other terms of the note.” Freddie Mac’s handbook has its custodian verify the note, its endorsements, and the assignments of the security instrument. Its delivery and verification lists do not include the security instrument itself or the title policy, and no title policy appears anywhere in the handbook. Ginnie Mae is the outlier. Within 12 months of issuance the issuer must deliver, for final certification, the “Original security instrument securing repayment of the indebtedness, signed by the mortgagor and recorded,” on which “A copy is acceptable only if the original has been lost and if it clearly shows evidence of recordation,” and for the title policy, “A copy of the Mortgagee’s title insurance policy is acceptable.” Ginnie Mae also carves out one class of issuer, which the manual calls an “R&W Issuer,” a term the chapters read here do not define: its custodian “may provide final certification of pools prior to receipt of the original recorded security instrument, title policies, original recorded intervening assignments, original recorded loan modification agreement, and original recorded NY CEMAs,” the last being New York consolidation, extension, and modification agreements, though the custodian “should have copies of the documents sent out for recordation, however, with a certification from the Issuer that the documents have been sent for recording,” and those issuers “must still procure the recorded security instrument, title policy and intervening assignments” in the ordinary course.

What will a custodian accept in place of a missing note?

A custodian accepts a lost note affidavit only where the agency authorized it: Fannie Mae by a single loan waiver, Freddie Mac by a written approval, waiver, or term of business, and Ginnie Mae never. Ginnie Mae accepts a lost instrument bond instead, in the form it prescribes, and only after initial certification or for three loan types.

Fannie Mae’s RDC puts the authorization first. Where the original note is missing “and the Seller has exhausted all reasonable means of obtaining the original note,” or where a replacement note cannot be signed by the borrowers, “Fannie Mae may authorize the Seller to substitute a Lost Note Affidavit, or similar substitute documentation for a missing note.” A loan delivered for initial certification without the original note requires the custodian to verify that a single loan waiver is in the file, and the Job Aids state the certification outcome in a table: a note that is not the original is “Fail Loan - Unless a Lost Note Affidavit (LNA) is included,” and an LNA “is acceptable only if the Lender has obtained Fannie Mae’s approval to submit LNAs (by presence of a copy of a Single Loan Waiver (SLW))” and the lender has exhausted all reasonable means of obtaining the original.

Freddie Mac’s handbook lists what the affidavit must be. “The LNA must be an original document, signed in ink by an officer of the Seller,” the officer’s signature must be notarized, the affidavit must carry the borrower names, original principal amount, security-instrument recording information, and note date, “A complete copy of the entire missing Note must be attached to the LNA, showing all required signatures and endorsements complete to the Seller,” and, in the handbook’s terms for a term of business (TOB) and a single loan exception (SLE), “The Seller must provide a document from Freddie Mac that approves use of the LNA, either copy of an email from Freddie Mac, a TOB, or an SLE that identifies the specific Mortgage or Mortgages to which it applies.” On the servicing side, Guide Section 8107.1(d) requires a servicer that learns a note is lost to “promptly conduct a thorough and diligent search of its premises and business records and make diligent inquiry of any party that has had physical responsibility for the Note, such as a Document Custodian or foreclosure counsel,” and it makes the servicer “responsible to Freddie Mac for the original Note even if it did not have physical possession of the Note at the time of loss.” The servicer then asks Freddie Mac for permission to create the affidavit, and the section lists four responses Freddie Mac may give, the last of which is “A repurchase request, if the request is not granted.”

Ginnie Mae refuses the affidavit. At initial certification, “Neither a lost instrument bond nor a lost note affidavit may substitute for a missing pooled note,” and the issuer “must obtain the borrower’s original signature on a copy of the pooled note, or the pool may not be certified.” The manual then opens one door, for three loan types, NY CEMAs among them: “for NY CEMAs, loan modifications, and Re-Performing loans a lost instrument bond with limited liability, in the form prescribed by Ginnie Mae, is permitted as indicated below,” and only where the bond was obtained from an unaffiliated insurance or surety company and comes with the power of attorney and certification the surety requires. What the bond stands in for is narrower than the loan: on a NY CEMA it “may substitute for a prior note listed in” the consolidated note’s Exhibit A, in an amount at least that of the missing note, and on a modified or re-performing loan it may substitute for “the note executed at the time the loan was made,” for the full amount of that note. For a missing consolidated note itself, at initial certification, “Neither a lost instrument bond nor a lost note affidavit is acceptable”; at recertification the custodian verifies that the consolidated note is an original “or that a lost instrument bond with limited liability that meets the requirements in Appendix I of this manual has been provided,” and the final-certification check on the prior consolidated notes listed on Exhibit A reads, “If a consolidated note is missing, verify that a lost instrument bond is present.” The manual closes the door on everything else at initial certification: “Substitution of a different form will not be accepted. Lost note affidavits are not acceptable.” The manual’s missing-document procedure in Chapter 7 allows the bond generally (“If any original note is missing, it may be replaced by a lost instrument bond”) and repeats the refusal (“A lost note affidavit is not acceptable”), and at recertification, “In the absence of the promissory note, for purposes of recertification, all documents required for final certification plus a lost instrument bond are required.” In our view a buyer who assumes the affidavit travels between programs meets the refusal at the next certification, because the instrument one agency accepted is the instrument the next refuses.

Why is a lost note indemnity not a substitute for the note?

A lost note indemnity is not a substitute for the note because an indemnity allocates a loss between two parties, while the note gives its holder the right to enforce the debt against a third. Freddie Mac’s Guide draws the same line: “Servicer acknowledges that creating an LNA does not relieve Servicer of any representation or warranty relating to enforceability of the Note and agrees to indemnify Freddie Mac under Section 8101.1(d) for any loss, damage or expenses that arise because the original Note is unavailable.” The affidavit itself must “State that, at the time that the Note was lost or destroyed, Servicer was entitled to enforce the Note” and must “Satisfy the requirements of applicable law to enforce the debt obligation in the State in which the Mortgage Premises is located,” and for each such state the servicer must hold “a legal analysis from either Servicer’s in-house counsel or outside counsel that the form of LNA used is as valid and enforceable as the Note would be if it were present.” The agency, in other words, treats the affidavit as a state-law question with the servicer’s own representation to Freddie Mac standing behind it. In our view the agency’s acceptance of the affidavit settles nothing between the seller and a non-agency buyer of the seller’s loan; what their sale agreement says about the note is a separate question.

Enforceability of a lost note is a state-law question, and the states have not adopted one text. The current uniform text of UCC Section 3-309 lets a person not in possession enforce the instrument if, among other conditions, that person was entitled to enforce it when possession was lost or “has directly or indirectly acquired ownership of the instrument from a person who was entitled to enforce the instrument when loss of possession occurred.” Minnesota enacts that text in Section 336.3-309 of its statutes. Delaware enacts the earlier uniform text in Section 3-309 of Title 6 of its Code, which requires that “the person was in possession of the instrument and entitled to enforce it when loss of possession occurred.” On their face those words describe the party that held the note when it went missing rather than a later purchaser. How a Delaware court would apply them to a purchaser is a question the statute does not answer, and this article does not either. Ohio carried that earlier language in Section 1303.38 of its Revised Code from August 19, 1994, and has carried the amended text, with the acquired-ownership prong, since September 28, 2016. New York’s Article 3 has no Section 3-309; its Section 3-804 permits the owner of a lost instrument to sue, but “The court shall require security, in an amount fixed by the court not less than twice the amount allegedly unpaid on the instrument, indemnifying the defendant.” Even under the amended uniform section, “The court may not enter judgment in favor of the person seeking enforcement unless it finds that the person required to pay the instrument is adequately protected against loss that might occur by reason of a claim by another person to enforce the instrument,” though “Adequate protection may be provided by any reasonable means.” In our view the state in which the property sits, not the form of the affidavit, decides what a lost-note loan is worth to a buyer.

How does an open exception interact with the delivery deadline and the repurchase trigger?

An open exception does not move the deadline, and the repurchase trigger runs on its own clock. In the material read here, Ginnie Mae’s consequences flow from the deadline and Freddie Mac’s from a declined lost-note request or a designated defect. Ginnie Mae requires that every pool “receive a Final Certification by an Approved Document Custodian within 12 months of the issue date of the related MBS,” and “The transfer of any MBS Program Pool to a new Issuer or to a new Document Custodian does not impact the deadline for Final Certification of the relevant pool.” The manual says the same thing from the custodian’s side: “If a pool or loan package is transferred to a new Issuer or to a new document custodian before final certification, the transfer does not extend the final certification deadline.” A pool that misses the deadline cannot pass to a new issuer, because “A pool or loan package that is past due for final certification may not be transferred to a new Issuer,” and it costs money, because Chapter 11, Part 9 requires an issuer with pools past due for final certification or recertification to post a letter of credit “equal to 100 percent of the aggregate remaining principal balance (RPB)” of the loans preventing certification. The requirement attaches once the issuer crosses the thresholds in that part: any pool issued more than three years earlier and not finally certified, or more than 19 past-due pools together with two percentage tests. The same part adds that “Issuers must repurchase defective mortgages according to the timeframes set forth in the Guaranty Agreements and the Guide”; the Guaranty Agreement was not read for this article. Where a document goes missing after final certification, “the Issuer must replace the missing document(s) within 90 days of the date of the written notice from the document custodian,” and if the problem is not resolved in that time, “The affected pools will be decertified, and the loan file will have to be corrected and the pool finally certified or recertified.” Ginnie Mae holds the issuer, not the custodian, for the result: “Ginnie Mae holds the Issuer responsible for any and all losses arising from defective or missing MBS Program Pool or loan documents.”

Freddie Mac’s repurchase clock is a separate instrument from its certification gate. In the Guide sections and the handbook read here, two routes, in Section 8107.1(d) and in Section 3602.2(a), can reach a custodial failure, and neither names the custodial exception itself. A lost-note request that Freddie Mac declines can be answered with “A repurchase request, if the request is not granted,” under Section 8107.1(d). And Section 3602.2(a) lets Freddie Mac require repurchase “if Freddie Mac has designated any loan-level deficiency that breaches a term contained in the Purchase Documents in effect at the time of Mortgage purchase as resulting in a Significant Defect (as such term is defined in Section 3401.1(a)),” after which “The Seller/Servicer must repurchase Freddie Mac’s interest in the identified Mortgage within 60 days of the date of Freddie Mac’s request or within such other time frame as specified by Freddie Mac.” Section 3401.1 was not read for this article, so the article makes no claim about which custodial failures Freddie Mac designates. Section 3602.2 also requires repurchase wherever “the repurchase is required under the terms of the Purchase Documents,” and its subsection (b) carries a separate track for servicing violations, with its own notice and correction period and a repurchase right for any servicing-related representation and warranty. This article does not analyze either. Before purchase, the consequence is the one in Section 6301.4: delivery is not complete, settlement cannot occur, and Freddie Mac may cancel or postpone the funding. Fannie Mae’s side is stated as a seller obligation rather than a clock: the seller/servicer “is responsible for the safekeeping of all documents required by Fannie Mae to be held by the document custodian and for all losses incurred by Fannie Mae because the document custodian it selected failed to perform its fiduciary responsibilities,” and Fannie Mae’s repurchase topics were not read for this article.

Practitioner takeaway

In our view the exception list is not one list, and what clears it is not on the exception report. It turns on which program the loan is bound for, which version of that program’s rulebook governs on the certification date, and what the agency has put in writing for the particular loan. It turns as well on what the seller’s own sale agreement says about the documents and the note. A seller that knows what the custodian is actually certifying reads its exception report with those facts in hand. A seller that does not learns the answers at settlement, from the party that cannot fund, and that is the work.
