Lien Deadlines: The Date on the Calendar Is Not the Date to Act

The state with the longest filing window has the shortest enforcement window. Owners can shorten your deadline with a document you never see. And in a dozen states somebody else can start a 30-day clock on you. Read this before you trust a number.

The state most dangerous to read casually

RHODE ISLAND GIVES YOU 200 DAYS TO FILE. That is the longest filing window in the country.
Rhode Island then gives you 40 DAYS TO ENFORCE, the shortest in the country, and you must get both the complaint and a notice of lis pendens in within it.
Longest window on one clock, shortest on the other. Anyone who reads the 200 and relaxes has read exactly the half that will not save him.
The general rule this illustrates: every state runs TWO clocks. One to file the lien, one to enforce it. They are unrelated in length and a long first clock tells you nothing about the second.

The owner can shorten YOUR filing deadline, and nothing obliges him to tell you

Alaska	120 days becomes 15 once a Notice of Completion is recorded
California	90 days becomes 30 for anyone other than the general contractor
Nevada	90 days becomes 40
Arizona	120 days becomes 60
Massachusetts	120 days becomes 90
Utah	180 days becomes 90
How it happens	Someone else records a document at the county. Your deadline moves on the day it is recorded, not on the day you find out.
What to do about it	On any job where the money is slow, check the recorder before you rely on the long number. Alaska is the extreme case: 120 days to 15 is not a trim, it is a different deadline.

After you file, somebody else can start a clock on you

30 days from a written demand	Illinois, Indiana, Iowa, Nebraska, New Jersey, North Dakota, South Dakota
60 days	Georgia (a recorded Notice of Contest), Ohio (a notice to commence suit), Tennessee (a written demand)
90 days	Mississippi (a recorded Notice of Contest)
Ohio is the widest of the lot	Six years becomes 60 days, and it is not only the owner who can do it. A MORTGAGEE, any other person with an interest, or a contractor who has posted a bond can all serve the notice. Miss it and the lien is void and the property wholly discharged. Your debt survives; your security does not.
Indiana matches that reach	Any party with an interest, expressly including a mortgagee or another lienholder, can require you to foreclose within 30 days.
Pennsylvania is the odd one out and worth knowing	Most states can force you to SUE on a lien you already hold. Pennsylvania can force you to CREATE it: an owner or contractor may file a rule requiring you to file your claim within 30 days of notice of the rule, or be forever barred.
Six states record the opposite in terms	Alabama, Massachusetts, Montana, New Hampshire, New Mexico and Utah each state that nobody can make you move sooner. For the rest we have not established it either way, so assume it can happen and diarize accordingly.

Filing the lien is not the finish. These states need a second step or it dies

Kentucky	Post a copy to the owner within 7 days of filing. The statute says the lien is DISSOLVED if you do not. Filing perfectly and skipping the letter loses it as completely as never filing.
Wisconsin	Serve a copy of the claim on the owner within 30 days of filing
Delaware	Certified mail to everyone else holding a lien on the property, within 10 days of filing
Arkansas	Suit is not enough. You need a lis pendens filed inside the same 15 months or the lien stops existing
North Dakota	Suit is not enough. No lis pendens and the lien is deemed satisfied
District of Columbia	A notice of pendency within 10 days of filing suit. Winning the race to sue and forgetting this loses it just the same
Louisiana	A notice of pendency inside the year, or the recorded privilege stops binding third parties and a buyer or lender takes free of it
Vermont	You must also cause the property to be attached in the action, not merely sue
Georgia	File notice of the action with the superior court clerk within 30 days of starting it
Oregon	Ten days' written notice to the owner and any mortgagee BEFORE you sue

Some states make you act BEFORE the filing deadline, so the real date is earlier

Colorado	A notarized Notice of Intent served on the owner and the principal contractor at least 10 days before you record, with an affidavit of service filed alongside the lien. No notice, no lien. Count back 10 days from the deadline and that is your date.
Arkansas	Ten days' notice to the owner before you file. Treat day 110 of the 120 as the cut-off, not day 120.
Georgia	The lien document itself must carry the expiry statement and the owner's right to contest. Leave either out and the lien is invalid however well you met the 90 days.
Mississippi	The 180-day expiry wording must appear on the face of the lien in 12-point bold, or it cannot be filed at all.
The pattern	A filing deadline is the last day the paperwork can land, not the day to start. Where a precondition exists, the precondition is your deadline.

Four states you cannot count from your last day on site

Texas	The clock runs from the 15th of the month, not from when you finished
Louisiana	Everything turns on whether a Notice of Termination gets filed. Filed: 30 days for a subcontractor, 60 for a general contractor. Not filed: 6 months and 7 months from substantial completion or abandonment
Tennessee	A remote contractor's lien runs 90 days from serving its own Notice of Lien, and a prime contractor's runs a year from completion
Hawaii	45 days, but from a DEFINED date of completion: two newspaper publications seven days apart plus an affidavit filed with the circuit court. If nobody ever publishes one, the date is deemed a year after work actually finished, so your 45 days may not have started yet

Built from a 51-jurisdiction dataset in which every row was read against the statute it cites and stamped with the date and the source. Where a state gives different deadlines to a general contractor, a subcontractor, a supplier and a laborer, the SHORTEST that can apply is the one shown, so the deadline checker can only ever tell you to move sooner than reality, never later. Bonded jobs, public work and federal contracts run on separate regimes (Miller Act and the state Little Miller Acts) that this does not cover. Use this to spot that you have a problem, not to calculate your date, and get advice before a deadline you cannot recover.
