By Anthony C. Adamopoulos, Divorce Mediator, Collaborative Divorce Attorney and Divorce Arbitrator
Before you begin the divorce process, there is one practical reality to understand: there are two very different starting points in Massachusetts divorce—and the one you choose will shape everything that follows.
Section 1B: The Litigation Starting Point
A divorce under Section 1B begins when one spouse files a Complaint for Divorce as the Plaintiff. This initiates a formal legal process that is, by its nature, adversarial—even when both parties hope to eventually settle.
Section 1A: The Agreement Starting Point
By contrast, a Section 1A divorce begins after the spouses have already reached agreement. Instead of starting as adversaries, they begin as participants in a shared resolution process.
Using Mediation or Collaborative Divorce to Reach Agreement
In mediation, the parties work together—with the help of a neutral mediator—to resolve three core issues:
- Parenting and child support
- Spousal support
- Division of assets
Once agreement is reached, attorneys finalize the documents and file a Joint Petition for Divorce under Section 1A, leading to an uncontested hearing.
Collaborative Divorce follows a similar non-adversarial path, with each spouse represented by specially trained counsel and supported by neutral professionals.
The Bottom Line
Section 1B starts a divorce as a legal conflict.
Section 1A completes a divorce as a mutual agreement.
Understanding this distinction can help you choose a path that protects your finances, your family, and your future.
