What we do

Counsel on the issues that actually cross your desk.

Your Form 990 is due. A donor is asking about a restricted gift. Your board chair just resigned, and the bylaws are ambiguous about succession. A state regulator wants a copy of your last three fiscal years’ audits. You need counsel who won’t need a primer first.

Commonlight Legal is a boutique law firm serving 501(c)(3) public charities and private foundations, fiscal sponsors, charter schools, and private and independent schools across New York, Washington, D.C., Massachusetts, and Connecticut. We advise executive directors, board chairs, and senior leadership on governance, compliance, employment, advocacy, administrative law, and transactional questions that determine whether a mission-driven organization can sustain itself and grow.

How we work

Six practice areas, drafted for nonprofit realities.

Outside General Counsel

Fractional in-house counsel. Strategic Counsel Subscription (5–20 hrs/mo) or Fractional GC (25–40 hrs/mo). Board-meeting attendance included.

Explore OGC

Entity Formation & Governance

State formation, Forms 1023/1023-EZ/1024, bylaws, fiduciary-duty counseling, ongoing 990 and charitable-registration compliance.

Explore Formation

Employment & Labor

Policies, handbooks, classifications (employees, contractors, volunteers), wage-and-hour, dispute counsel — counseled by an attorney who's seen both sides.

Explore Employment

Advocacy & Lobbying Compliance

501(c)(3) advocacy limits, 501(h) elections, 501(c)(4) structures, federal and state lobbying registration. Advocate boldly and do it right.

Explore Advocacy

Charter & Independent Schools

Authorization, federal CSP grants, administrative appeals before the CT SDE and Superior/Appellate Court, special-education reimbursement.

Explore Schools

Litigation: Administrative Law

A focused niche practice. Charter-school administrative appeals today; expanding into adjacent nonprofit administrative-law matters. Not general civil litigation.

We represent nonprofits at risk through We The Action's Nonprofit Legal Defense Network and serve as board directors and trustees.
