About me

Tim Leighton counsels clients in Central Illinois and metropolitan Washington, DC as a lawyer and Certified Financial Planner™ practitioner on trust, estate, business planning, succession, transactions, charitable planning, and tax matters.

Most business clients are closely held enterprises and tax-exempt organizations. They rely on Tim for formation, transition, transaction, employment, and development needs. Tim also helps with strategies to recruit, retain, and reward key people. Through the Eleventh Judicial Circuit in Illinois, the National Arbitration Forum, and privately, Tim helps resolve business and financial disputes as mediator and arbitrator.

He helps clients find better ways to secure peace of mind and to preserve, protect, and grow assets. Tim serves families with meaningful net worths and others with dependency and guardianship concerns, such as school-aged children and people with disabilities. As trustee, he implements client priorities while managing substantial assets. Clients also rely on the firm for trust administration and probate.
