Who this applies to

New Mexico's rule binds every link in the payment chain: owners, contractors and subcontractors [2]. An "owner" under the Act includes a local public body or a state agency, other than the Department of Transportation [2], so the same prohibition reaches private and public work.

One category of project is outside the Act. It does not apply to construction contracts for residential property containing four or fewer dwelling units [2].

What the rule says

When making payments, an owner, contractor or subcontractor may not retain, withhold, hold back or in any other manner fail to pay amounts owed for work performed [2]. The retainage figure is therefore 0% [2], in both regimes.

With nothing held back, there is no retainage release to schedule. The statute's timing rules cover prompt payment, late-payment interest and final payment instead. Interest runs at one and one-half percent [2] of the undisputed amount per month, or fraction of a month, until payment is issued. For an owner's payment it starts on the 22nd day [2] after the payment was due; for payments from contractor to subcontractor and further down the chain it starts on the eighth day [2]. A local public body paying with grant money may instead take up to 45 days [2] after an undisputed request, if the contract and every page of the plans state the longer period conspicuously.

How to comply

This page states what the Act provides; it cannot decide whether a particular contract or project falls under it. The chapter text in the Sources below, the contract and a lawyer answer that.

What changed recently

Section 57-28-5 was enacted by Laws 2001, ch. 68, § 5 [2] and amended by Laws 2007, ch. 213, § 4 [1], effective June 15, 2007 [2]. The 2007 act removed the retainage provisions, renamed the Retainage Act the Prompt Payment Act, and repealed §§ 57-28-4, 57-28-6, 57-28-9 and 57-28-10 [1].
