Letter of Agreement (LOA)
A Letter of Agreement (LOA) is a written document that outlines the terms and conditions agreed upon by two or more parties before or in place of a formal contract. In government contracting, it often serves as a preliminary understanding that defines scope, responsibilities, and expectations. An LOA may be binding or nonbinding depending on its language and intent.
What Is a Letter of Agreement?
A Letter of Agreement (LOA) is a written document that outlines the terms and conditions agreed upon by two or more parties before or in place of a formal contract. In government contracting, it often serves as a preliminary understanding that defines scope, responsibilities, and expectations.
An LOA may be binding or nonbinding depending on its language and intent.

How It Works in Government Contracting
Where it appears in the procurement lifecycle
An LOA may appear during early project discussions, interagency coordination, grant arrangements, or when work must begin before a fully executed contract is finalized.
Who uses it
Federal agencies, state and local governments, contractors, subcontractors, and partnering organizations may use LOAs to document mutual understanding.
Why it matters
It clarifies expectations and reduces risk before formal contract execution. It helps align scope, schedule, and cost assumptions.
Practical application
A government agency may issue an LOA to authorize preliminary services such as research, transition planning, or mobilization activities while the final contract is being processed.
Regulatory Framework
There is no single Federal Acquisition Regulation section dedicated solely to Letters of Agreement. However, LOAs may intersect with:
Federal Acquisition Regulation
FAR Part 16 covering contract types
FAR Part 43 covering contract modifications
Agency specific supplements such as DFARS or state procurement codes
The enforceability of an LOA depends on contract formation principles and the specific language used.
Why It Matters for Contractors
An LOA can authorize early work and accelerate project timelines.
Contractors must ensure the LOA clearly defines authority, funding status, and scope to avoid unauthorized commitments.
It can strengthen relationships by demonstrating alignment before formal contract award.
If poorly drafted, an LOA may create ambiguity about payment, liability, or binding obligations.
Common Misconceptions
An LOA automatically replaces a formal contract.
It does not.
All LOAs are legally binding.
Binding status depends on wording and intent.
An LOA guarantees future contract award.
It does not unless explicitly stated.
Frequently Asked Questions
Is a Letter of Agreement legally binding?
It can be. The binding nature depends on the language, signatures, and intent of the parties.
How is an LOA different from a Memorandum of Understanding?
An LOA typically contains more detailed operational terms. An MOU often reflects general intent without detailed obligations.
Can work begin under an LOA?
Yes, if the LOA explicitly authorizes work and funding. Contractors should confirm proper authority before starting.
Can an LOA be modified?
Yes. Modifications should be documented in writing and signed by authorized representatives.
