FAR and DFARS › DFARS Part 237: Service Contracting › Subpart 237.1

DFARS 237.106 Funding and term of service contracts.

The codified text (eCFR, as of 2026-10-02). Under the Revolutionary FAR Overhaul ↗, agencies follow class deviations with new text for many parts while the formal rules go through the Federal Register: check the solicitation and your contract's clauses, which rule.

In plain English

This DFARS section limits how long certain service contracts can run. Personal service contracts for experts or consultants cannot exceed one year, and severable services contracts may cross fiscal years only if the total period is one year or less. It matters because it caps contract duration and affects how you structure options or orders.

Applies to: DoD contracts for personal services of experts or consultants, and severable services

What it requires

  • Keep personal service contracts for expert or consultant services to no more than 1 year
  • Ensure the nature of duties is temporary (not more than 1 year) or intermittent (not cumulatively more than 130 days in 1 year)
  • Ensure a severable services contract, option, or order that crosses fiscal years does not exceed 1 year
