Under K.S.A. 16-1803, the general contractor must pay subcontractors within 10 days after receiving payment from the owner, and if the owner doesn’t pay within 30 days of the invoice, interest at 1% per month accrues on late amounts. Your subcontract should mirror these statutory deadlines so that late payments automatically trigger the statutory interest and remedies without negotiation.

Kansas does not cap retainage by statute on private construction; retainage is negotiable between the GC and sub. On public works under K.S.A. 60-1112, retainage is generally governed by contract terms, commonly 5%. Your agreement should specify the exact retainage percentage, the release schedule (typically at substantial completion and final completion), and payment of statutory interest on withheld retainage.

While Kansas has not enacted a blanket statutory ban on pay-if-paid clauses, courts and statutes in most states treat "pay-when-paid" as a reasonable timing provision rather than an absolute condition. Check Kansas Statutes Annotated Chapter 60, Article 11 (Kansas Mechanic’s Lien Law) and Prompt Pay provisions at K.S.A. 16-1801 et seq. (Private Sector Prompt Payment Act) for specific restrictions, and make sure your subcontract states that payment from the owner is not an absolute condition precedent to your right to be paid.

Kansas does not require statutory lien waiver forms; waivers are enforceable if they clearly identify the project, amount, and date. Under K.S.A. 60-1111, a lien waiver is effective only to the extent of payment actually received, protecting subs from signing waivers for bounced checks. Never sign an unconditional waiver until payment has actually cleared your bank account, and make sure your waiver identifies the specific billing period and amounts to avoid losing lien rights on future work.

Kansas does not have a specific anti-indemnification statute for construction contracts; broad-form indemnity is generally enforceable if clearly worded. Subcontractors should negotiate express limits and rely on the Prompt Payment Act for late-payment remedies. Always read the indemnification clause carefully — even in states with anti-indemnity statutes, "broad form" indemnity for joint negligence is typically still enforceable.

Kansas requires filing a lien within 3 months of the last work or materials furnished, followed by foreclosure within 1 year of filing. Kansas requires subcontractors (not in direct privity with the owner) to serve a written Notice of Intent by certified mail within 75 days of first furnishing labor or materials to preserve lien rights. Send statutory notices by certified mail or another trackable method, keep copies of everything, and calendar the deadlines immediately upon each project’s completion.
