File and terminate a lien

Middesk’s Lien Filing service enables you to file UCC liens with state authorities and terminate existing liens programmatically. This capability is essential for lenders, financing companies, and creditors who need to secure their interests in business assets or release those interests when obligations are satisfied.

Filing a UCC (Uniform Commercial Code) lien establishes a legal claim against a debtor’s assets as collateral for a loan or other financial obligation. This public record:

Secures your interest in business assets
Establishes priority among creditors
Provides legal protection for your financial interests
Creates a public record of the security agreement

When the debt is satisfied or the security interest is no longer needed, you can file a termination to release the lien and clear the debtor’s record.

Understand lien status

Liens and terminations progress through different states during the filing process:

Lien filing statuses

Status	Description	When it occurs
`created`	Lien request has been created	When you submit the filing request
`pending`	Middesk is processing the filing	When Middesk begins fulfillment
`filed`	Filing has been submitted to the state	After state submission
`open`	Filing has been reflected in state records	After Lien Reflection confirms the filing (if enabled)

Termination statuses

Status	Description	When it occurs
`created`	Termination request has been created	When you submit the termination
`pending`	Middesk is processing the termination	When Middesk begins fulfillment
`completed`	Termination has been filed with the state	After successful state submission

Once a termination is completed, the associated lien status changes to closed.

How to file a lien

Filing a lien is a straightforward process that involves submitting debtor and secured party information to Middesk. But you must first create the business in your Middesk account, which triggers the business verification process.

Create a business

Create the business in Middesk, if it doesn’t already exist. You can do this in the Dashboard or through the API.

$ curl -X POST https://api-sandbox.middesk.com/v1/businesses \
>   -u <YOUR_API_KEY>: \
>   -H "Accept: application/json" \
>   --data '{
>     "name": "Example Business Inc",
>     "addresses": [
>       {
>         "address_line1": "123 Main Street",
>         "city": "San Francisco",
>         "state": "CA",
>         "postal_code": "94105"
>       }
>     ],
>     "tin": {
>       "number": "123456789"
>     }
>   }'

The response includes a business_id that you’ll use to order the liens filing:

1 {
2   "id": "2c6bcf81-21c8-4f71-b6c0-1e738338dadf",
3   "object": "business",
4   "name": "Example Business Inc",
5   "status": "pending",
6   ...
7 }

Prepare the lien filing data

Before filing, gather the required information:

Debtor information, business or individual owing the debt (name, address)
Secured party information, your organization’s details as the creditor
Collateral description, description of assets securing the debt
Loan details, principal amount and terms
State-specific requirements, additional fields based on filing jurisdiction

File the lien

Once the business is verified and approved in your Middesk account, submit the lien filing using the Dashboard or a create a lien API call.

Required parameters:

debtors, array of debtor objects with name and address information.

Each debtor object should include at most one address. State-specific limits apply to the number of debtors per filing.
