Recording and enforcing a Connecticut lien

Recording the lien

Record with the town or city clerk. Electronic recording is not generally available, so build mailing time into the deadline. The lien must be notarized. The lien claim must be sworn to under oath.

After recording

A copy of the recorded lien must be served on the property owner within 30 days of recording. To keep the lien alive it must be enforced by lawsuit within 1 year after the lien is recorded.

Wrongful lien exposure

Connecticut has no dedicated wrongful-lien penalty statute, but an inflated or baseless lien can still be challenged and removed at the claimant's expense.
