Adopting Due Diligence: How to Begin Your Donor Due Diligence Strategy

September 13, 2025 (6 min read)
Donor due diligence best practices include monitoring negative news, watchlists, and legal documents for red flags.

When a donation offer lands on your desk, the instinct is to say yes. But in the fundraising space, it is important to ask the question, "Is the gift safe?"

Reputational threats, funding from opaque sources, and increasing donor scrutiny have changed the rules of engagement. Development officers and prospect researchers now face a new reality: every donor relationship is either a potential risk or a reputational asset.

A robust due diligence search should be at the top of any fundraiser’s priority list. In this article, we’ll outline why due diligence is important, go over some common challenges to the due diligence process and give you best practices for risk management with donor due diligence tools.

Why due diligence is important for nonprofits

Managing risk and compliance for a nonprofit involves getting the full picture of any potential donor or partner. Just as for-profit institutions must ensure that their partners and employees are fulfilling the legal and ethical standards of practice, nonprofits need to do this as well. And, they must check that the donations they receive come from viable, trustworthy sources. 

Problems with basic donor vetting

Many nonprofits and university advancement teams still rely on basic vetting: a quick Google search, a name-check against the major watchlists. But modern threats are more sophisticated. Consider: 

  • A high-net-worth donor whose wealth stems from controversial industries that conflict with your mission 
  • A cryptocurrency donation routed through anonymous wallets, making source validation nearly impossible 
  • A family foundation board member with ties to ESG controversies or legal disputes 

Any one of these could turn a seemingly generous gift into a public liability. And once donor trust is broken, it’s incredibly difficult to rebuild.

Donor risk lessons from the headlines

Several high-profile cases show just how fast things can go wrong: 

Sackler Family & Tufts University 

Tufts faced backlash for accepting millions from the Sacklers, owners of Purdue Pharma. Despite removing the Sackler name from campus, the reputational damage lingered. 

Jeffrey Epstein & MIT 

Despite Epstein’s criminal history, MIT accepted donations totaling $850,000. The fallout led to resignations and deeply shook the institution’s credibility. 

Martin Shkreli & Community Solutions 

After accepting a $15,000 donation from Shkreli, who was later arrested for securities fraud, the nonprofit returned the funds and publicly disavowed the association. 

Each case underscores the same truth: no gift is worth sacrificing public trust. 

Best practices for building safer donor relationships

The solution is a smarter approach. This begins with a risk map which is a structured framework for helping to identifying potential threats such as reputational, financial, and compliance risks before they surface. It's almost like a GPS for navigating donor relationships with confidence.  

Ask Donors Questions Before Accepting a Gift:

  • Does the donor’s history align with our mission? 
  • Can we verify where the money is coming from? 
  • Are there any legal, ethical, or media red flags? 
  • Could this relationship raise concerns among our stakeholders? 

When vetting becomes a strategic habit, organizations protect their ability to fundraise and grow with integrity.

Monitor negative news

After the initial searches have been conducted, remember that circumstances may change. Ongoing efforts to continually vet donors, like monitoring news alerts, can help ensure that your thoroughly checked sources are still viable and accurate throughout time.

Donor tracking tools will often set alerts for donors and affiliations to ensure fundraisers can stay up to date on media mentions for potential issues that might build into larger public stories or donor scandals. For instance, a nonprofit might set up an alert for each major donor’s name and see that one of their larger contributors was recently charged with embezzlement. This would give them the opportunity to sever the relationship and remove the donor from all future outreach campaigns to combat any negative association before it gets out of hand.

Check for regulatory infractions

Beyond wanting to avoid donors whose public actions don’t align with the nonprofit’s ethos, there is also the question of legality. In some rare cases, donors might be caught up in sanctioned businesses or be on watch lists, making it illegal to conduct business with them.

Legal liability checks are important and can be done with the help of due diligence tools that will watch these lists, as well as arising legal cases, to steer clear from anyone who might put the nonprofit in harm’s way. Fundraising employees can also manually check the sanctions lists at places like the SEC website for immediate access.

What's at stake if you don't conduct due diligence

Failure to vet donors stands as an organizational liability bearing potential risks. 

  • Reputational crises can lead to lost donor trust and damage years of brand-building 
  • Major gift reversals or withdrawals can derail long-term campaigns 
  • Legal issues can implicate board members and halt programs in progress 

After its founder’s scandal, one cancer nonprofit saw donations fall from $47M to under $17M in just three years. The price of overlooking donor risk is steep. 

First steps: where to begin today

If you’re unsure about where to start, begin here: 

  1. Run a donor gap analysis: Review your top 25 donors. Note when they were last vetted and identify any due diligence blind spots. 
  2. Build a risk map: Define your thresholds for donation size, funding source opacity, and reputational risk. Assign tiers accordingly. 
  3. Adopt tools that scale: Don’t rely on manual searches, rather, use platforms that combine broad data access with workflow automation, such as built-in alerts and reporting. 

Prospect researchers and development professionals need fast, reliable tools to reduce research blind spots. That’s where platforms like Nexis® for Development Professionals step in.
