If you've ever sent a letter of support request to a partner and gotten back something so generic it could've been written for any grant on the planet — these templates are for you.

Letters of support can be one of the most powerful parts of your grant proposal. They show reviewers that your project has real community backing, real partnerships, and real commitment. But most letters of support are puff pieces — vague, impersonal, and forgettable.

The secret? Write them yourself, then hand them to your partners to personalize and sign. These templates make that process fast, easy, and foolproof.

This download includes three fully customizable Word document templates:

1. Community Support Letter For organizations, leaders, or community stakeholders endorsing your project. This template walks you through establishing community need, applicant credibility, and a strong closing — all with fill-in-the-blank prompts so nothing gets missed.

2. Working Partnership Letter The most detailed template in the pack — designed for active collaborators with specific roles in your project. Covers everything reviewers want to see: partner qualifications, specific responsibilities, financial arrangements, in-kind contributions with dollar values, referral commitments, joint reporting obligations, mutual benefit, and sustainability beyond the grant period. If money is moving between organizations, this template makes sure it's documented clearly.

3. Legislator / Elected Official Letter A template designed for you to draft on behalf of an elected official and send to their office for review and signature. Includes prompts for constituent connection, policy alignment, and applicant credibility — plus tips on briefing the legislative aide and building a relationship that can lead to future appropriations.

Every template includes:

• Fill-in-the-blank prompts in bold teal so you never miss a detail

• Gray italic coaching notes that guide you through each section (delete before sending)

• A "How to Use These Templates" instruction page

• Quick tips on length, who should sign, and when to start collecting letters

• Reminders to include project name, applicant name, funder name, and signer contact information in every letter

Who is this for?

Grant writers, nonprofit development staff, program managers, and anyone who's ever chased down a letter of support the week before a deadline. Whether you're submitting your first proposal or your fiftieth, these templates save you time and make your letters stronger.

Format: Microsoft Word (.docx) — fully editable so you can customize for any grant, any partner, any project.
