When more than one creditor has a claim against the same property, lien priority works chronologically: whoever perfected their claim first gets paid first, and everyone else lines up behind them in the order they filed. A senior lienholder collects in full before a junior lienholder sees a dollar, which is why a first mortgage carries a lower interest rate than a second one. The rule has exceptions that matter, and the mechanics of how you lock in a priority date are more technical than they look, but the chronological spine holds across American property law.1Internal Revenue Service. IRS Chief Counsel Advice 200922049 – Priority of Federal Tax Lien: First in Time, First in Right
For personal property secured under Article 9 of the Uniform Commercial Code, the formula is phrased slightly differently: “first to file or perfect.” Competing perfected security interests rank by whichever creditor filed a financing statement or perfected first, and that date sticks even if the loan itself closes later.2Legal Information Institute. PEB Commentary No. 30 Sections 9-309 and 9-322(a)(1) The underlying idea is the same: the clock starts when you put the world on notice, not when you handed over the money.
How a Creditor Locks In a Priority Date
Making a loan does not, by itself, give you priority. You have to take the formal step that puts your interest in the public record. That step is called perfection, and it creates constructive notice: anyone searching the records can find your claim.3Legal Information Institute. Perfection Until you perfect, you may have a contract with the borrower, but you don’t have a priority date the rest of the world has to respect.
Real Estate
For real property, perfection means recording a mortgage or deed of trust at the county recorder’s office where the property sits. The document needs a legal description sufficient to identify the parcel, and the timestamp on the recorded instrument fixes your place in line. An error in the legal description or the borrower’s name can undermine the filing and cost the lender its position.
Personal Property
For personal property such as equipment, inventory, or accounts receivable, creditors typically perfect by filing a UCC-1 financing statement with the secretary of state. The requirements are minimal: the debtor’s name, the secured party’s name, and a description of the collateral.4Legal Information Institute. UCC 9-502 Contents of Financing Statement A UCC-1 does not have to state the amount of the debt, and the debtor’s signature isn’t required. Getting the debtor’s exact legal name right is critical, though, because future creditors search by name. A misspelling can render the filing ineffective, which means the lien effectively doesn’t exist.
Fixtures
Some collateral sits on the border between personal and real property. Equipment bolted to a building may become a fixture that a real estate mortgage could cover. A creditor financing that equipment protects itself with a fixture filing, a specialized financing statement recorded in the real property records rather than with the secretary of state. The filing must describe the related real property and indicate it covers fixtures.5Legal Information Institute. UCC 9-334 Priority of Security Interests in Fixtures and Crops Skip the fixture filing and the equipment lender’s claim is generally subordinate to the mortgage holder.
Why “First in Time” Doesn’t Always Mean “First to Record”
States don’t all use the same system for resolving a priority fight. Three recording-statute frameworks exist in the United States, and which one applies can change who wins.
- Pure race: the first party to record wins, full stop. It doesn’t matter whether the second buyer knew about an earlier unrecorded deed. Only a handful of states use this approach.
- Notice: a later buyer who pays value without knowledge of an earlier unrecorded interest wins, even without recording first. The question is whether the later buyer had actual or constructive notice.
- Race-notice: a later buyer wins only if they both lacked notice of the prior interest and recorded first. This is the most common framework.
In notice and race-notice states, bona fide purchaser status is what the fight turns on. A bona fide purchaser pays value without reason to suspect problems with the seller’s title.6Legal Information Institute. Bona Fide Purchaser If a prior interest was already in the records, the later buyer had constructive notice of it and can’t claim that protection. The practical rule for anyone lending or buying: run the title search, then record immediately.
Liens That Jump the Line
Several categories of liens override the chronological rule. These super-priority liens can cut ahead of previously recorded interests, so a first-position lender isn’t always as safe as the recording date suggests.
Property Tax Liens
Local property tax liens are the most powerful exception. In virtually every state, a property tax lien automatically takes priority over all other liens and encumbrances, including a previously recorded first mortgage, with no filing requirement for the tax authority. This is why mortgage lenders almost universally require borrowers to escrow for property taxes: an unpaid tax bill becomes a lien that jumps ahead of the mortgage.
Purchase Money Security Interests
A purchase money security interest (PMSI) arises when a lender provides the money used to buy the very collateral securing the loan. Under UCC Article 9, a PMSI in non-inventory goods gets super priority over earlier-filed security interests as long as the creditor perfects before or within 20 days after the debtor takes possession.7Legal Information Institute. UCC 9-324 Priority of Purchase-Money Security Interests For inventory, the rules are stricter: the PMSI holder must perfect before delivery and send notice to existing secured creditors who have filed against the same type of collateral. The exception exists because the PMSI lender is the reason the collateral is in the debtor’s hands at all.
HOA Assessment Liens
Roughly 20 states give homeowners association assessment liens a limited super priority over first mortgages. The typical structure caps that priority at six months of unpaid common assessments. If a homeowner falls behind on dues and the HOA forecloses, the association can collect up to that capped amount ahead of the first mortgage. Some states allow up to nine months; others set different limitations. Mortgage lenders who assumed their first-recorded position was unassailable sometimes learn otherwise here.
Mechanics’ Liens
Mechanics’ liens protect contractors and suppliers who improve real property. In many states, these liens “relate back” to the date visible construction work began on the property rather than the date the lien was actually filed. If a contractor started a renovation in January and a mortgage was recorded in March, a mechanics’ lien filed months later may outrank the mortgage because its priority dates to January. Not every state does this. Some tie priority to when the specific claimant first provided labor or materials, and others use the recording date of a notice of commencement.
Federal Tax Liens Are Not Automatic Super Liens
A common misconception deserves correcting. Federal income tax liens do not automatically jump ahead of previously recorded mortgages. Under the Internal Revenue Code, a federal tax lien arises when a taxpayer owes and fails to pay after demand.8Office of the Law Revision Counsel. 26 USC 6321 – Lien for Taxes But that lien is not valid against a holder of a security interest, a mechanics’ lienor, or a judgment lien creditor until the IRS files a notice of federal tax lien in the appropriate public records.9Office of the Law Revision Counsel. 26 USC 6323 – Validity and Priority Against Certain Persons
The ordinary first-in-time rule applies. If your mortgage was recorded before the IRS filed its notice, your mortgage holds priority. If the IRS filed first, the tax lien outranks you. Federal tax liens are powerful because they attach to all of a taxpayer’s property at once, but they don’t leapfrog earlier-perfected interests the way local property tax liens do. That distinction catches a lot of people off guard.
Subordination Agreements and Equitable Subrogation
Priority can be rearranged by agreement or, sometimes, by a court.
Voluntary Subordination
Lienholders can trade places through a subordination agreement. The common scenario is refinancing: a homeowner has a first mortgage and a home equity line of credit and wants to refinance the first mortgage. The new lender needs first position, but the HELOC was recorded earlier than the replacement loan. The HELOC lender signs a subordination agreement and voluntarily steps behind the new mortgage. The party giving up priority has to sign, and the agreement should be recorded so future creditors can see the modified order.
Equitable Subrogation
Priority can also shift without a signed agreement. Under the doctrine of equitable subrogation, a court can grant a refinancing lender the same priority position held by the old mortgage it paid off. This matters when the refinancing lender pays off a first mortgage without realizing an intervening lien exists. Without the doctrine, the intervening lienholder would get a windfall promotion from second to first simply because the refinancing lender replaced the original senior loan.
Courts applying equitable subrogation generally require the refinancing lender to show it intended first position and didn’t know about the intervening lien. Negligence in failing to search title can weigh against the lender, though many courts and the Restatement (Third) of Property treat a title search mistake as insufficient by itself to bar the remedy. The point is preventing unjust enrichment, not rewarding carelessness.
Judgment Liens
Not every lien is voluntary. When a creditor wins a money judgment, they can convert it into a lien against the debtor’s real property by filing a certified copy of the judgment abstract in the appropriate public records.10Office of the Law Revision Counsel. 28 USC 3201 – Judgment Liens The judgment lien’s filing date fixes its rank. A judgment lien recorded after an existing mortgage sits behind that mortgage; a judgment lien recorded before a later mortgage sits ahead of it.
Judgment liens typically last 6 to 20 years depending on the state, and most jurisdictions allow renewal. A prejudgment attachment can create a lien even before the case is decided, locking in a priority date while litigation is pending. These involuntary liens are particularly risky for property owners because they can appear without the owner’s participation.
How Bankruptcy Disrupts Priority
A bankruptcy filing can upend the priority framework. The moment the debtor files, an automatic stay freezes virtually all collection activity, including any attempt to create, perfect, or enforce a lien against estate property.11Office of the Law Revision Counsel. 11 USC 362 – Automatic Stay A narrow exception lets perfection continue if done within certain statutory windows, but creditors who haven’t perfected before the filing are in trouble.
The Trustee’s Strong-Arm Power
A bankruptcy trustee is treated as a hypothetical bona fide purchaser of real property and a hypothetical judicial lien creditor for personal property as of the filing date.12Office of the Law Revision Counsel. 11 USC 544 – Trustee as Lien Creditor and as Successor to Certain Creditors and Purchasers If a lien wasn’t properly perfected before the filing, the trustee can avoid it entirely and convert the secured claim into an unsecured one. A definite spot in the priority line becomes a spot at the back of a very long queue.
Preference Avoidance
Even perfected liens aren’t automatically safe. The trustee can claw back transfers made within 90 days before the filing, or one year for insiders, if the transfer allowed the creditor to receive more than they would have in a liquidation. Lien perfections that happened shortly before filing are within reach. Exceptions exist for transactions in the ordinary course of business and substantially contemporaneous exchanges, and the creditor carries the burden of proving them.13United States Department of Justice. Civil Resource Manual 58 – Avoidance Powers
Lien Stripping in Chapter 13
Junior lienholders face a particular threat in Chapter 13. If the property’s value has fallen below what the senior lienholder is owed, a junior mortgage can be stripped off entirely because the collateral provides no value to support it. The junior creditor’s claim is reclassified as unsecured and typically paid pennies on the dollar through the plan.
How the Money Actually Gets Distributed
When property is sold through foreclosure or judicial auction, the proceeds move down the priority waterfall in a fixed order. Administrative costs of the sale come off the top. The first-priority lienholder is paid until the debt is satisfied in full. Anything left flows to the second-priority claimant, and so on. Only after every valid lien is paid does a surplus return to the former property owner.
Junior lienholders are often wiped out. If the sale price doesn’t cover even the first mortgage, nothing reaches anyone below it. A junior lienholder whose lien is extinguished by a senior foreclosure doesn’t necessarily lose the right to collect, though. In many states the junior creditor can pursue a personal deficiency judgment against the borrower for the unpaid balance, though some states restrict or prohibit deficiency actions depending on the loan type and foreclosure method.
Who starts the foreclosure also changes the picture. When a junior lienholder initiates it, senior liens survive the sale and stay attached to the property. The buyer at that auction takes title subject to all senior encumbrances, which depresses the sale price and often makes a junior foreclosure economically pointless unless there’s substantial equity above the senior debt.
