The ShieldVIN Guide
A working reference for banks, credit unions, and asset-backed lenders on collateral risk — the questions underwriting and portfolio teams actually ask, answered first, with sources. Not a blog: pages are kept current, and each carries a visible updated date.
- What is a collateral clearinghouse?
The category, defined: a private network where lenders check an asset's identifier against every other member's claims before money moves — a credit bureau for collateral.
- Is there a MERS for auto loans?
No — and the gap is wider than 'no MERS'. What MERS actually does, what ELT, NMVTIS, and the Coast Guard registry cover, and what none of them checks.
- How lenders verify a vehicle isn't already financed: five methods compared
Title records, ELT, history reports, UCC search, clearinghouse check — what each can see, how fast, and which ones can catch another lender's brand-new loan.
- Duplicate financing: how the same VIN gets funded twice
The mechanics — dealer-channel double-flooring, application timing, and innocent refinance overlaps — and why every lender's file looks perfect.
- Auto loan portfolio due diligence: the collateral checklist
The widely-cited checklists review credit files, servicing, and the tape — and almost all stop before the collateral. The steps that verify the vehicles themselves.
- What is a lien tape?
The collateral-identity columns of a loan tape — and how to Sweep one against the outside world before you buy.
- Double-pledged collateral in a portfolio purchase
The same vehicles, pledged to multiple lenders at once — how it happened at portfolio scale, and how a buyer detects it before funding.
- Does NMVTIS show liens?
No — and the misconception matters. What the national title system actually contains, what a clean NMVTIS report does and doesn't tell a lender.
- Powersports, RV and marine: where titling is weakest
Some states title boats, some only register them; many don't title off-highway vehicles at all. Every gap in titling is a gap in lien visibility.
