Mechanic’s lien claims are attached to a real estate property, while credit scores are attached to an individual or business entity.
While it’s unlikely that the recorded mechanic’s lien claim would be directly linked to any individual’s personal credit report, it’s also quite likely that owners or general contractors who issue payments in a delinquent manner will incur damage to their credit scores. Any bill that is turned over to a collection agency will damage credit scores.
A foreclosure action to perfect a mechanic’s lien claim will almost certainly damage the credit score of the property owner. Mechanic’s lien claims are publicly recorded declarations of a debt owed by the property owner, so it’s quite likely that credit rating agencies will become aware of any unresolved mechanic’s law claim.
