Recording and enforcing a South Dakota lien
Recording the lien
Record with the register of deeds for the county. 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
South Dakota does not require a separate notice after the lien is recorded, though most claimants send one anyway to prompt payment. To keep the lien alive it must be enforced by lawsuit within 6 years after the lien is recorded.
Wrongful lien exposure
South Dakota has no dedicated wrongful-lien penalty statute, but an inflated or baseless lien can still be challenged and removed at the claimant's expense.
Practitioner notes for South Dakota
Lien filing deadline: file statement of lien within 120 days after last furnishing labor or materials (SDCL §44-9-15). Statement must be verified by oath and filed with the register of deeds (SDCL §44-9-16). Foreclosure/enforcement: SD mechanic’s lien enforcement is tied to bringing an action; a common limitation is 6 years (general actions on record/obligation limitations), so this sheet encodes 72 months as a placeholder; confirm exact foreclosure limitation and any shorter lien-duration rules in SDCL §44-9-23 and related sections.
Statutory sources: SDCL §§ 44-9-15, 44-9-23, 15-2-13. Read the South Dakota lien statute.
