What Is a UCC-1 Lien?
A UCC-1 is a Uniform Commercial Code filing. When a company wants to establish a legal claim on personal property used as collateral, it files a UCC-1 with the state. The filing is public record. It tells future buyers and lenders that someone else has a claim on that property.
In residential solar, UCC-1 filings appear in two situations. Solar lease agreements often include a UCC-1 fixture filing that claims the solar panels as equipment belonging to the leasing company. Some solar loan products also file UCC-1s as a security interest in the equipment.
Most homebuyers do not know this is happening. It does not always surface in a standard title search until a real estate attorney or title company specifically looks for it.
What Happens at Resale
When a home with a UCC-1 solar lien goes to market, buyers and their lenders encounter a complication. The solar equipment is claimed by a third party. To close the transaction, one of three things has to happen.
First, the buyer agrees to assume the solar lease, taking over the monthly payments and the ongoing obligation to the solar company. Not all buyers are willing to do this, and some lenders will not allow it.
Second, the seller pays off the lease balance at closing. Depending on how much of the lease remains, this can run into tens of thousands of dollars and reduces the seller's net proceeds significantly.
Third, the deal falls apart. Buyers walk, realtors lose commissions, title companies flag the issue, and the transaction stalls.
