When an Arizona listing changes from Active to UCB or Pending, the seller has accepted an offer. The important difference is whether the property is still being marketed for backup offers.
In ARMLS terminology: UCB means Under Contract–Backups and is a sub-status of Active; the seller has accepted an offer and wants the property marketed for backup offers. Pending means an acceptable offer has been received and the property is no longer being marketed for sale. See the ARMLS status explanation.
What UCB means for a buyer
The primary buyer already has a contract. You may still have an opportunity to submit a backup offer, but you are not bidding against an unsold home. A backup contract has its own terms and should be reviewed carefully. Ask your agent to verify the current ARMLS status, contact the listing agent and explain how your position would work if the primary contract ends.
Do not assume that a UCB label reveals which contingency is open or how likely the primary transaction is to close. Those details may be confidential or may change as the transaction progresses.
What Pending means for a buyer
The property is under contract and the seller is not actively marketing it for additional offers. Consumer websites may display or remove the listing differently, so confirm the status through a current MLS source. You can tell your agent that you remain interested, but continue searching rather than planning around a transaction you do not control.
What the choice means for a seller
The listing broker and seller choose the appropriate status based on the accepted contract and the seller’s written marketing instructions, following ARMLS rules. UCB can keep the property visible for backup opportunities. Pending communicates that the home is no longer being marketed. Neither label lets a seller ignore the rights of the primary buyer or simply replace that contract with a better offer.
UCB is not the same as CCBS
ARMLS also uses CCBS—Contract Contingent on Buyer Sale—when the accepted offer is contingent on the buyer selling a property and the seller continues marketing for backup offers. The labels communicate different transaction circumstances, so ask for the exact status instead of using “contingent” as a catch-all.
A practical buyer checklist
- Confirm the live MLS status and when it was last updated.
- Ask whether the seller is inviting backup offers.
- Review a proposed backup contract, deadlines and earnest-money terms with your agent.
- Keep financing and inspection resources ready.
- Continue evaluating active homes until you control a primary contract.
A practical seller checklist
- Discuss the correct ARMLS status with the listing broker immediately after acceptance.
- Decide whether continued showings and backup marketing support your goals.
- Give required instructions in the proper form.
- Keep marketing claims consistent across the MLS and consumer sites.
- Update status promptly as the transaction changes.
Frequently asked questions
Can a seller accept a backup offer in UCB?
UCB signals that the seller is marketing for backups. Any backup agreement must respect the existing primary contract.
Is a UCB home available like an Active home?
No. It is already under contract. The backup position only becomes primary if the first contract ends according to its terms and the backup agreement takes effect.
Does Pending guarantee the sale will close?
No transaction is guaranteed until closing is complete. Pending describes marketing status, not certainty.
