Frequently Asked Questions

Everything You Need to Know Before Getting Started

Mediation is a voluntary process where a trained, neutral third party helps both sides communicate, understand each other’s interests, and reach a fair agreement, without a judge deciding the outcome for you.

Mediation is typically faster, less expensive, and more private than litigation. You and the other party stay in control of the outcome, rather than leaving decisions about your family or business to a judge.

Not necessarily. Many clients complete mediation without individual attorneys, though you’re always welcome to consult one. We can also work alongside your existing legal counsel throughout the process.

We handle divorce, unmarried paternity, child custody, child and spousal support, and general civil disputes. If you’re unsure whether your situation qualifies, schedule a consultation and we’ll walk you through it.

Yes. Sessions are available in person, by phone, or over Zoom, so you can resolve your matter from anywhere with the same level of service as a face-to-face meeting.

It depends on the complexity of your case. Some matters resolve in a single half-day session; others require a series of shorter sessions. We’ll outline a realistic timeline during your consultation.
