A donor agreement establishes the terms of a significant gift, including how the funds may be used, the reporting requirements the organization accepts, and what happens if the organization is unable to fulfill the purpose of the gift.

Restricted gifts are the highest-risk category. When a donor gives funds designated for a specific program, the organization has accepted a legal obligation to use those funds for that purpose. Misuse of restricted funds is a serious matter: in California, the Attorney General’s office has enforcement authority over nonprofit charitable assets. Most states have an equivalent oversight mechanism.

A well-drafted donor agreement also includes the IRS acknowledgment language required for donors claiming deductions on gifts over $250, which protects the donor and documents the organization’s compliance with federal tax law.

Volunteer agreements serve two purposes. They establish the expectations for the volunteer engagement, including role, schedule, and conduct standards. And they address the liability questions that arise when volunteers are injured during their service or when volunteers cause harm to third parties.

Liability waivers for volunteers vary in enforceability by state. California limits what can be waived in advance for future negligence. New York and Texas have their own standards. A generic waiver may not be enforceable in the state where the organization operates.

Furthermore, volunteer agreements should include confidentiality provisions covering any donor information, client data, or organizational information the volunteer will access in their role. Volunteers who handle sensitive information without a confidentiality agreement create exposure that is preventable.

Grant agreements with foundations, government agencies, and corporate funders are among the most legally consequential documents a nonprofit signs. They establish reporting requirements, allowable expenses, clawback provisions for unspent or misspent funds, and intellectual property ownership over materials created with grant funds.

The clawback provisions deserve particular attention. Many grant agreements allow the funder to demand return of grant funds if reporting requirements are not met, if the funded program does not achieve specified outcomes, or if the organization is found to have misrepresented its activities. Understanding these provisions before signing is essential for any organization managing significant grant funding.

Nonprofits sign vendor agreements for technology platforms, office supplies, event services, catering, printing, and dozens of other operational needs. Each one creates payment obligations, delivery expectations, and liability exposure.

The vendor agreements most likely to create significant problems are those involving technology platforms that handle donor data. Data processing agreements, HIPAA business associate agreements for health-related nonprofits, and privacy terms under state privacy laws including California’s CCPA must be reviewed before a nonprofit shares sensitive data with any vendor.

Nonprofits are employers in every legal sense that matters. Employment law applies equally to 501(c)(3) organizations and for-profit corporations. Employee classification, wage and hour compliance, at-will employment provisions, and anti-discrimination obligations are all fully applicable.

Contractor agreements require particular attention. The IRS and state tax agencies apply independent contractor classification tests that are separate from the organization’s intent. A worker classified as an independent contractor who should be classified as an employee creates significant tax liability and potential regulatory exposure.

Board governance documents are the legal infrastructure that protects the organization’s tax-exempt status and shields board members from personal liability. Conflict of interest policies, whistleblower protections, document retention schedules, and investment policies are all required or strongly recommended under IRS Form 990 guidelines.

State attorneys general in California, New York, and Massachusetts require certain governance documents as a condition of charitable registration. Failure to maintain current, signed conflict of interest policies can trigger regulatory scrutiny during state registration renewals.
