UCC 9-406 notice requirements after debtor default - timing questions
We had a borrower default on their equipment loan last month and I'm trying to understand the UCC 9-406 notice requirements for notifying account debtors. The collateral includes accounts receivable and we need to collect directly from their customers now. I've read the statute but I'm confused about the timing - do we need to send the UCC 9-406 notice before we start collecting or can we send it after we've already made contact with the account debtors? Also, does the notice need to be sent certified mail or is regular mail sufficient? Our UCC-1 was filed properly two years ago and we have a valid security interest, but I want to make sure we don't mess up the collection process by not following the notice requirements correctly. Has anyone dealt with this situation recently?

You definitely need to send the 9-406 notice BEFORE you start collecting from the account debtors. The whole point is to notify them that they should now pay you instead of the original debtor. If you've already contacted them without proper notice, you might have issues. The statute doesn't specify certified mail but I always recommend it for proof of delivery.

•This is correct. The notice protects both you and the account debtor. Without it, they could argue they paid the wrong party in good faith.

•Wait, I thought you could collect first and then send notice? I've seen lenders do it both ways.

I went through this exact situation last year. You absolutely must send the UCC 9-406 notice before demanding payment from account debtors. The notice needs to identify the security agreement, describe the accounts, and instruct them to pay you directly. Regular mail is technically sufficient but certified gives you proof. Make sure your notice is clear about where payments should be sent.

•Did you have any account debtors refuse to pay after getting the notice? I'm worried about pushback.

•A few questioned it initially but once I provided copies of the security agreement and UCC-1 filing, they complied. The key is being professional and providing documentation.

•What if the account debtor says they already paid the original debtor after default but before notice?

I've been dealing with UCC collections for 15 years and the 9-406 notice timing is critical. You send it BEFORE collecting, not after. The notice must be authenticated (signed) and should include: 1) identification of the security agreement, 2) description of the accounts assigned, 3) instruction to pay the secured party. No specific delivery method required but certified mail recommended for larger amounts.

•This is super helpful. Do you have a template you use for these notices?

•I don't share templates but any good commercial law attorney should have one. The key elements I mentioned are what matter most.

•What about electronic notice? Can you email the 9-406 notice instead of mailing?

Had a similar issue last month and found this document verification tool called Certana.ai that helped me cross-check all my UCC documents before sending notices. You can upload your UCC-1, security agreement, and draft notice to make sure everything aligns properly. Caught a discrepancy in how I described the collateral that could have caused problems. Just upload the PDFs and it verifies consistency across all documents.

•Interesting, never heard of that tool. Did it help with the actual notice language or just document consistency?

•It verified that my collateral description in the notice matched what was in the UCC-1 filing. Also flagged that my debtor name had a slight variation between documents.

•That sounds useful. I've had issues before where small discrepancies caused big headaches with account debtors questioning validity.

UGH the whole 9-406 process is such a pain. I had one account debtor lawyer up immediately after getting the notice and demanded copies of everything. Took weeks to resolve and meanwhile they weren't paying anyone. The system is broken.

•That's frustrating but not uncommon. Account debtors get nervous when they receive these notices. Having your documentation ready helps.

•Did the lawyer find any issues with your notice or were they just being difficult?

•They were being difficult. Everything was proper but they still dragged it out. Eventually paid but cost me time and money.

Quick question - does the 9-406 notice need to be notarized? I've seen conflicting information on this.

•No notarization required. Just needs to be authenticated, which usually means signed by an authorized person.

•Some lenders notarize anyway for extra formality but it's not legally required under Article 9.

Make sure you keep detailed records of when you sent each notice and to whom. If you end up in litigation, you'll need to prove proper notice was given. Also consider whether any account debtors are in different states - might affect service requirements.

•Usually the security agreement specifies governing law, but notice requirements can vary by state where the account debtor is located.

•This is getting complicated. Maybe I should just hire a collection attorney to handle the whole thing.

I use Certana.ai for all my UCC document reviews now. After I had one notice rejected because my collateral description didn't match the UCC-1 exactly, I started using their document checker. You just upload your security agreement and UCC-1 filing, then your draft notice, and it verifies everything is consistent. Saves a lot of headaches.

Don't forget about the account debtor's right to request proof of the assignment under 9-406(c). They can demand reasonable proof that the account has been assigned to you. Be prepared with copies of relevant documents.

•What constitutes 'reasonable proof'? Is a copy of the security agreement enough?

Aisha Mohammed
•Usually the security agreement plus evidence of default (demand letter, acceleration notice) is sufficient. Sometimes they want to see the UCC-1 filing too.

•I always include the UCC-1 search results showing our filing is active. Gives them confidence we're legitimate.

Just went through this process and one thing I learned - if you have a large number of account debtors, consider staggering the notices. Sending them all at once can create a flood of calls and questions. Also, have a dedicated person ready to handle inquiries because you'll get them.

•How many account debtors constitutes 'large'? I have about 50 to notify.

•50 is definitely large enough to stagger. Maybe send 10-15 per day over a week. Gives you time to handle questions before the next batch.

Final thought - make sure your notice clearly states when the assignment became effective. Some account debtors will try to argue they can pay the original debtor for work done before the assignment. Be clear about the cutoff date.

•Good point. I usually tie it to the date of default or acceleration notice.

•What if work was completed before default but invoiced after? Who gets paid for that?

•That gets complicated and depends on how the accounts are defined in your security agreement. Usually the secured party gets paid if the account existed at the time of assignment.

This is really helpful information everyone! As someone new to UCC collections, I'm getting clarity on the process. Just to confirm my understanding: I need to send the 9-406 notice BEFORE collecting from account debtors, it should be signed/authenticated, certified mail is recommended but not required, and I need to include identification of the security agreement, description of assigned accounts, and payment instructions. I'm also seeing mentions of Certana.ai for document verification - has anyone else used this tool? It sounds like it could help catch those small discrepancies that cause big headaches later. Thanks for all the practical advice!
