Yes. North Carolina has a standard form for exactly this, the Back-Up Contract Addendum, Standard Form 2A1-T, and it attaches to an ordinary Offer to Purchase and Contract to put you in second position behind the deal already in place. You can walk away without penalty any time before the seller tells you in writing that you have moved up, which makes a backup offer much lower risk than most buyers assume.
Buyers ask this after losing a house they wanted, usually when the listing says under contract and they cannot accept that the search starts over. It is a fair instinct. Contracts do fall apart during due diligence, and when one does, the seller’s choice is between relisting and picking up a contract that is already signed.
What makes this workable in North Carolina is that the form was written by the North Carolina Bar Association and NC REALTORS together, and it handles the two things that would otherwise make a backup offer dangerous: when your money becomes committed, and when your clock starts running.
How the North Carolina backup form works
Form 2A1-T, revised July 2026, is an addendum. You write a normal offer on the standard contract and attach the addendum, which names the primary buyer by last name and states that your contract sits behind theirs.
Paragraph 1 makes the whole thing conditional. Neither you nor the seller has to perform until the primary contract is terminated. Paragraph 2 defines what counts as terminated, and it is specific: a written release signed by everyone in the first deal, a written notice from the seller exercising a right to terminate, a written notice from the primary buyer exercising a right to terminate, or a court judgment. Nothing informal counts.
Paragraph 7 is the hinge. If the primary contract does terminate, the seller must promptly give you two things: written notice that your contract has become primary, which the form calls the Notice of Primary Status, and written evidence that the first deal actually ended. Until that notice lands, you are not on the hook for anything.
What happens to your money and your deadlines
This is where the form earns its keep, and it is the part we walk buyers through line by line before they sign.
- Any initial earnest money deposit goes to the escrow agent under paragraph 1(d) of the standard contract even while you are in backup position, and is deposited promptly NC REALTORS and North Carolina Bar Association Standard Form 2A1-T, revised 7/2026
- Any additional earnest money is due by 5 p.m. on a date counted in days after the Notice of Primary Status is delivered to you Standard Form 2A1-T, revised 7/2026
- The due diligence fee becomes payable when the Notice of Primary Status is delivered, and must be delivered within two days after that Standard Form 2A1-T, revised 7/2026
- The due diligence period runs through 5 p.m. on the last day of a negotiated number of days following delivery of the Notice of Primary Status, not from the date you signed Standard Form 2A1-T, revised 7/2026
- The settlement date is likewise counted in days from delivery of the Notice of Primary Status Standard Form 2A1-T, revised 7/2026
Read that list again, because it answers the question buyers are really asking. Your inspection window and your closing date do not burn while you wait. They start when you move up. The form even tells you to write “See attached Form 2A1-T” in those blanks on the main contract rather than putting dates there.
The due diligence fee deserves a flag. In North Carolina that fee is paid to the seller and you generally do not get it back, which our post on closing costs for a buyer in Wilmington covers in more detail. In a backup contract it is not due at signing. It becomes due when you are told you are primary, and it has to be delivered within two days of that notice, so the money needs to be sitting ready rather than spent on something else.
How you get out, and how the deal dies on its own
Paragraph 9 gives you a clean exit. You may terminate the backup contract without liability by giving the seller written notice at any time before you receive the Notice of Primary Status, and your earnest money comes back. If you find a better house next weekend, you send a notice and you are done.
Paragraph 6 handles the ordinary outcome. If the primary contract closes, your backup contract is void and your earnest money is refunded. Paragraph 10 adds a hard stop: you fill in a date, and if you have not received the Notice of Primary Status by 5 p.m. on that date, the contract is null and void and your deposit is returned. The form puts the words “TIME BEING OF THE ESSENCE” in capitals in that paragraph, which tells you how literally it is meant.
Two more provisions worth knowing. Paragraph 4 says modifying the primary contract, including extending its deadlines, does not count as terminating it and does not move you up. A primary buyer who keeps asking for more time keeps you waiting. Paragraph 5 says you may not see the primary contract without written permission from both the seller and the primary buyer, though the seller does state the primary settlement date on the form, which at least tells you what you are waiting on. Paragraph 3 then has the seller indemnify you if they terminate the first deal wrongly and you rely on it.
Is a backup offer worth writing in this market?
Often, no. That is the honest answer, and it depends on the number of other houses you could buy instead.
New Hanover County had 1,251 active listings in September 2026, up 7.6 percent from a year earlier, and homes were taking 61 days to sell against 34 a year ago, per our New Hanover County market update. In a market with that much standing inventory and that much time on market, a buyer who ties up attention waiting on one address usually does worse than a buyer who keeps touring. The backup offer made far more sense in 2021.
Where we still use it is for property that is genuinely not replaceable: a specific lot on the water, a floor plan a builder no longer offers, the one house on a street you have decided on. For that, a backup costs you a signature and nothing else until the seller sends notice. Our property search is the better first move in most cases, and if you want help weighing the two, the Buyer Advantage Program is where we do that work with clients.
A backup contract is a real contract, and the paperwork does not protect you from the emotional cost of waiting. We have watched buyers stop looking because they were sure the first deal would collapse, and then it closed. The form also cannot be used for a short sale, which has its own addendum, and it gives you no visibility into the primary contract, so you are guessing about how likely that deal is to fail. If the primary buyer keeps extending deadlines you simply keep waiting, because extensions are not terminations. And North Carolina law makes the attorney, not your agent, the person who advises you on contract language, so have one read the addendum before you sign it. Our post on whether you need a real estate attorney in North Carolina explains why.
Related questions people also ask
Does the seller have to accept my backup offer?
No. A seller is free to ignore a backup offer, and some do, because signing one commits them to a second contract while the first one is still alive. Others welcome it, since a signed backup means they do not have to relist if due diligence goes badly. Your agent can ask the listing agent whether the seller will consider one before you spend time writing it.
Can I write a backup offer on more than one house at a time?
Nothing in the North Carolina form stops you from being in backup position on two properties, and because the buyer can terminate without liability before receiving notice that the contract has become primary, the exposure is limited. The practical risk is that two sellers send you that notice in the same week, at which point you would be bound on both unless you terminate one first. If you are considering it, talk to a North Carolina real estate attorney about sequencing, because the timing is where people get caught.
What happens to my earnest money while I am in backup position?
Under the North Carolina form, any initial earnest money deposit still goes to the escrow agent and is deposited promptly, even though your contract is in second position. You get it back if the primary contract closes, if you terminate before receiving the Notice of Primary Status, or if the deadline in the automatic termination paragraph passes without that notice. The money is held, not spent, and the escrow agent rather than the seller holds it.
Before you write a backup offer, ask the listing agent two questions: whether the seller will sign one, and what the settlement date on the primary contract is. Those two answers tell you whether waiting is worth it, and we are happy to make those calls for you and talk through whether this house is the one worth waiting on.
