SD · PRIVATE CONSTRUCTION CLAIMS
Prepare a verified, itemized statement.
Section 44-9-15 generally requires filing within 120 days after the last covered work, skill, services, materials, or machinery.
Notices to check before filing
Review the commencement and notice provisions that apply to your role; filing the final statement does not answer every earlier-notice question.
Where and how to file in South Dakota
Ordinary improved-premises claims are filed with the county register of deeds. The statute identifies a different office for the special claim category it references.
A filing mistake to avoid
An invoice total alone does not supply the statement’s first and last dates, parties, property identification, and itemized account.
Prepare your project records
Assemble the first and last contribution dates, owner and contracting-party addresses, itemized account, and property description.
- Identify who hired you and whether the property is privately owned.
- Confirm your notice obligations and the event that starts each time limit.
- Verify the owner and property description using appropriate records.
- Reconcile invoices, payments, credits, and disputed amounts.
- Keep filing and service receipts, and calendar any enforcement deadline.
After the claim is filed
Filing does not guarantee payment or establish that a disputed claim is valid. Preserve the filed document and delivery evidence. If payment arrives, arrange the required release or satisfaction. If the balance remains unpaid, seek advice about enforcement before its separate deadline expires.
Help with your unpaid construction account
The Credit App offers administrative mechanics lien preparation and a recording attempt for $249. Confirm your state, project, notices, and timing before ordering. The service uses the information you provide; it does not determine legal sufficiency, verify ownership, or represent you in an enforcement action.
