I want to file a lean on a house from a promissory note. Can I?

No, your deadline to file the mechanics lien has passed if the note is "old."

You should file a collection lawsuit.

Without knowing more, you may be able to file a breach of a promissory note and if that note is secured by real property, a lis pendens recorded against the property may be in order. Contact a lawyer in your area.

Nope, a mechanics lien is intended to create a security interest in real property for work that improved that real property (e.g., labor, materials, equipment). A promissory note wouldn't qualify. What you're looking for is a "deed of trust" securing the promissory note.
