A mortgage affidavit is a sworn, notarized statement in which you confirm specific facts about a property or a mortgage loan under penalty of perjury. You’ll run into one during a home purchase, a refinance, or any situation where a lender or title company needs verified proof of something the rest of the paperwork can’t establish on its own. Because the statement carries the same legal weight as testimony given in court, a knowingly false claim can trigger federal penalties of up to $1,000,000 and 30 years in prison.1Office of the Law Revision Counsel. 18 USC 1014 Loan and Credit Applications Generally
How It Differs From the Note and the Deed
A mortgage affidavit isn’t a contract. Your promissory note is a promise to repay money. Your deed of trust or mortgage gives the lender a security interest in the property. An affidavit does neither. It’s a declaration of existing facts, made under oath, that other parties can rely on as if you had testified in court.
That difference matters. When you sign an affidavit, you aren’t agreeing to future terms. You are personally vouching for the accuracy of every statement in the document. Lenders, title companies, and closing attorneys use these sworn statements to fill gaps that other documents leave open: a name discrepancy in the chain of ownership, a question about how you plan to use the home, a missing original note from a prior servicer. Each gets a sworn answer that becomes part of the permanent loan record.
The Types You’re Likely to See
“Mortgage affidavit” is a catch-all. Several distinct versions show up at different points in a real estate transaction.
Affidavit of Title
This is the one most homebuyers encounter. The seller signs it at or before closing to confirm ownership and disclose anything that could cloud the title. A typical affidavit of title includes sworn statements that the seller is the sole owner of record, that no other buyer has been promised the property, that no undisclosed liens or assessments exist, and that the seller has not filed for bankruptcy. If a known issue exists, such as an existing mortgage being paid off at closing or an easement affecting the property, the affidavit identifies it and explains how it’s being handled.
Occupancy Affidavit
Lenders price loans according to how you plan to use the property. Owner-occupied homes default far less often than investment properties or second homes, so rates and underwriting standards differ. Borrowers claiming a primary residence often sign a separate occupancy affidavit at closing swearing to that intent. Fannie Mae, for example, requires owner-occupants to move in within 60 days of closing and remain for at least one year.2Fannie Mae. Owner Occupant Certification Falsely claiming a home as your primary residence to shave a rate is one of the most common forms of mortgage fraud.
Lost Note Affidavit
Promissory notes get lost, destroyed, or misplaced, especially when loans have been sold between lenders. When the original can’t be located, the lender or servicer must file a lost note affidavit before enforcing the loan or completing a transaction involving it. Under the Uniform Commercial Code, the party claiming the right to enforce a lost instrument has to prove the terms of the original and show the loss wasn’t the result of a voluntary transfer.3Legal Information Institute. UCC 3-309 Enforcement of Lost, Destroyed, or Stolen Instrument The affidavit typically includes details about the borrower, the original loan amount, the interest rate, and the circumstances of the loss. Courts also require adequate protection against the risk that someone else appears later with the original note, which usually means the lender provides an indemnification guarantee.
Name and Signature Affidavit
If your name appears differently across documents, whether from a maiden name, a legal name change, or a typo in an older recorded document, a name affidavit confirms that the different versions all refer to you. A signature affidavit does the same job for variations in how you sign. Both are common and usually straightforward.
When One Gets Required
Home purchases. Almost every closing includes at least one affidavit. The seller provides an affidavit of title, and the buyer may sign an occupancy affidavit if claiming the property as a primary residence. Name discrepancies in the title chain bring in a name affidavit.
Refinances. If you’re refinancing a first mortgage while keeping a home equity loan or line of credit in place, the new lender will require first lien position. The holder of the second lien has to agree to stay behind. Fannie Mae requires a recorded subordination agreement whenever subordinate financing remains during a refinance,4Fannie Mae. Subordinate Financing and the process often pulls in sworn statements about the existing liens and their terms.
Title defects and record corrections. Property records aren’t always clean. A deed may have a misspelled name. A deceased prior owner’s estate may not have been properly settled. A satisfaction of mortgage may never have been recorded even though the loan was paid off years ago. Affidavits can resolve these problems by providing sworn factual statements that fill the gaps, often faster and cheaper than going to court.
Foreclosure and loan enforcement. When a lender can’t locate the original note, a lost note affidavit is required before foreclosure or any other enforcement action can proceed. Courts scrutinize these closely because the consequences for the borrower are severe.
What’s Inside One
Contents vary by type, but every mortgage affidavit includes a core set of elements: the affiant’s full legal name and address; the property’s legal description, address, and parcel number; a description of the affiant’s relationship to the property or transaction; the specific factual statements being sworn to; a declaration that everything in the document is true and correct under penalty of perjury; the affiant’s signature; and a notary block.
For an affidavit of title, the factual statements focus on ownership, liens, and encumbrances. For an occupancy affidavit, they center on intent to use the property as a primary residence and the timeline for moving in. For a lost note affidavit, they cover the terms of the missing note, the circumstances of the loss, the steps taken to find it, and the indemnification promise. Every statement must rest on the affiant’s personal knowledge, not secondhand information or assumptions.
How Notarization Actually Works
An affidavit without notarization is generally just a statement on paper. Notarization is what gives it legal force. What the notary does, though, is narrower than most people think. The notary confirms your identity, witnesses your signature, and administers an oath or affirmation. The notary doesn’t verify that your statements are true, doesn’t review the document for accuracy, and takes no responsibility for the content.
Mortgage affidavits typically require a jurat, which is stricter than a simple acknowledgment. With an acknowledgment, you can sign beforehand and confirm to the notary that the signature is yours. A jurat requires you to sign in the notary’s physical presence and verbally swear or affirm that the contents are true. A silent nod doesn’t count. The notary then completes a certificate confirming the oath was administered and the document was signed in front of them.
Most states now permit remote online notarization, where you appear via live video rather than in person. Whether your lender or title company will accept a remotely notarized affidavit depends on the transaction and the parties involved, so ask before assuming you can handle everything from your laptop.
What Happens If a Statement Is False
This is where mortgage affidavits carry real teeth. Because the document is sworn under oath, a false statement isn’t a paperwork issue or a simple breach of contract. It can be a federal crime.
Federal law makes it a crime to knowingly submit a false statement to influence the action of a federally insured financial institution, which covers virtually every mortgage lender in the country. The maximum penalty is up to $1,000,000 in fines and up to 30 years in prison.1Office of the Law Revision Counsel. 18 USC 1014 Loan and Credit Applications Generally For transactions involving HUD or FHA loans, additional statutes apply with their own penalties.5U.S. Department of Housing and Urban Development. Criminal Statutes Those maximum figures are reserved for the most egregious cases. Even a single false statement on an occupancy affidavit, though, can result in the lender calling the entire loan balance due immediately.
Occupancy fraud is the most common way borrowers get tripped up. Claiming a property as your primary residence when you actually intend to rent it out or keep it as a second home might save you a fraction of a point on your rate. The savings are trivial next to the risk. Lenders monitor for this after closing, and the consequences range from loan acceleration to criminal prosecution. The affidavit you signed is the evidence they’ll use.
Recording Fees and Practical Costs
Not every mortgage affidavit gets recorded with the county. Those that affect the public record, like an affidavit correcting a title defect or a name affidavit clearing up a chain-of-title issue, typically do. Recording fees vary by jurisdiction and are usually charged per page or as a flat rate. Expect anywhere from a few dollars to around $25 per page depending on your county. Your title company or closing attorney handles the recording as part of closing, and the fee shows up on your closing disclosure.
Beyond recording, the main cost is the notarization itself, which in most states runs between $5 and $25 per signature. When you’re working with a title company or closing attorney, notarization is usually bundled into closing costs rather than billed separately. The document itself is free; your lender or title company provides the form.
