UCC 1-201(b)(35) definition causing filing headaches - anyone else confused?
I've been wrestling with UCC 1-201(b)(35) for weeks now and it's driving me crazy. We're trying to file a UCC-1 for some manufacturing equipment but the definition requirements under 1-201(b)(35) are making our collateral description a nightmare. Our legal team says we need to be more specific about the security interest scope but every time we revise the description to match what we think 1-201(b)(35) requires, the filing gets kicked back. Has anyone dealt with this specific definitional issue? I'm starting to wonder if there's something fundamental I'm missing about how this section applies to equipment collateral. The SOS portal keeps rejecting our filings and I'm running out of time before our loan closing date.

UCC 1-201(b)(35) trips up a lot of people because it's defining "security interest" itself, not just collateral descriptions. Are you sure the rejections are actually about the collateral description and not something else like debtor name formatting? The portal error messages can be misleading sometimes.

•You might be right - the error just says "insufficient collateral description" but maybe it's interpreting our description wrong because of how we're structuring it under the 1-201(b)(35) framework.

•This is exactly why I always double-check my understanding of these definitions before filing. The security interest definition in 1-201(b)(35) is foundational but it doesn't directly dictate collateral description format.

OMG yes! I had the same issue last month with 1-201(b)(35) confusion. Spent hours trying to make our collateral description match what I thought the definition required. Turns out I was overthinking it completely.

•What was the solution? I'm desperate at this point.

•I ended up using Certana.ai to cross-check my UCC-1 against the loan documents. Uploaded both PDFs and it flagged that my collateral description was actually fine - the problem was a tiny debtor name discrepancy I never would have caught manually.

•Interesting tool mention. How does it handle the definitional aspects like 1-201(b)(35)?

Look, 1-201(b)(35) is just defining what constitutes a security interest in general terms. It's not prescriptive about collateral descriptions on your UCC-1. You're probably getting rejected for something much simpler like formatting or debtor name issues.

•But our lawyer specifically said we needed to consider 1-201(b)(35) when drafting the collateral description. Now I'm more confused than ever.

•Your lawyer might be overthinking it too. The definition in 1-201(b)(35) establishes what IS a security interest, but your UCC-1 collateral description just needs to reasonably identify the collateral. Two different things.

Wait are we talking about the same 1-201(b)(35)? I thought that was about something completely different... let me look this up

•UCC 1-201(b)(35) defines 'security interest' - it's pretty fundamental to Article 9 filings.

•Oh right, I was thinking of a different subsection. Thanks for clarifying!

I've seen this exact confusion before. The definition in 1-201(b)(35) creates the legal foundation for what you're doing, but it doesn't change the practical requirements for UCC-1 collateral descriptions. You still just need to reasonably identify your collateral - all equipment, manufacturing equipment located at [address], specific serial numbers, whatever works for your situation.

•So I've been overthinking this whole thing? The rejections might not even be related to 1-201(b)(35) at all?

•Probably. Post your exact error message and maybe we can figure out what's really going wrong.

•This is why I always verify everything before filing. So many people get stuck on definitional issues when the real problem is usually something basic.

THE FILING SYSTEM IS DESIGNED TO CONFUSE PEOPLE! These definitional requirements like 1-201(b)(35) make everything unnecessarily complicated. Why can't they just make it simple?

•I mean, it's complicated because secured transactions are complicated. But I agree the portal error messages could be clearer.

•No excuse for bad error messages in 2025. These systems should be user-friendly by now.

Had a similar issue recently and tried that Certana tool someone mentioned earlier. It actually helped me spot inconsistencies between my security agreement language and UCC-1 description that I never would have caught. The 1-201(b)(35) stuff is important conceptually but probably not your immediate filing problem.

•Did the tool specifically help with definitional compliance or just general document consistency?

•More about consistency. It compared my docs and flagged where things didn't align properly. The definitional stuff is more about legal interpretation than filing mechanics.

This thread is making me feel better about my own filing confusion last week. I spent way too much time researching definitions when I should have been focusing on basic filing requirements.

•We've all been there! The key is separating legal theory from practical filing requirements.

•Exactly. Now I know to focus on the basics first before diving into definitional analysis.

For what it's worth, I've never had a UCC-1 rejected specifically because of 1-201(b)(35) compliance issues. Usually it's debtor names, missing info, or collateral descriptions that are too vague. Your rejection is probably about something more straightforward.

•That's reassuring. I'll go back and check the basic elements more carefully.

•Good approach. Start with the obvious stuff before worrying about complex definitional issues.

UPDATE: I used Certana to check my documents and found the real issue - there was a middle initial discrepancy between our debtor name on the UCC-1 and the actual business registration. Had nothing to do with 1-201(b)(35) at all. Sometimes you just need fresh eyes on the documents.

•Oh sorry, different person with similar issue! But sounds like we had the same root cause - overthinking definitions when it was really about basic accuracy.

•This is exactly what happened to me too. The tool caught stuff I completely missed while I was focused on the wrong things.

I'm new here but dealing with a very similar situation! Reading through this thread has been incredibly helpful - I was also getting stuck on UCC 1-201(b)(35) thinking it directly impacted my collateral description format. Sounds like I should step back and check the basic filing elements first (debtor names, addresses, etc.) before assuming it's a definitional compliance issue. Has anyone found a good checklist for the most common UCC-1 rejection reasons? I don't want to make the same mistake of overthinking the complex stuff while missing something simple.

•Welcome to the community! You're definitely on the right track - focus on the basics first. I don't have a specific checklist handy, but from what I've seen in this thread and my own experience, the most common issues are: debtor name discrepancies (even tiny things like middle initials), incorrect addresses, vague collateral descriptions, and formatting problems. The definitional stuff like 1-201(b)(35) is important for understanding the legal framework but rarely causes actual filing rejections. Maybe @Millie Long or @Debra Bai have a good checklist they could share since they seem to have dealt with this before?
