Family Law Mediation

Clients experiencing a dissolution of marriage, custody or support litigation and deciding what steps to take during this process are often the most stressful and emotional events and decisions of one’s life. The cost of going to court and pursuing an adversarial path is often extremely expensive and emotionally taxing on parties. Often parties have very little control over their own lives when their case is decided in a courtroom. Understanding this adversarial process, Ms. Keenan-Rivero not only offers individual representation for family law litigants but also offers comprehensive mediation services by acting as a neutral third-party mediator. When dealing with family law issues, mediation often benefits couples by offering a resolution alternative that is often less costly and faster than litigation. It also frequently leaves couples with a better understanding of the complexity of their dissolution, parentage, support, and/or custody matters, and often results in a more favorable outcome for everyone concerned. Mediation is a voluntary process where the parties work together individually or with their own individual attorney with Ms. Keenan-Rivero a neutral third party. Ms. Keenan-Rivero brings her twenty years of family law experience to assist parties as a mediator in devising a settlement that is mutually acceptable to both parties. The mediation process often gives the parties the freedom and opportunity to formulate more creative solutions to complex issues, is less stressful and a process where parties are able to focus more effectively on their children’s and individual needs.

Lawyers as mediators are knowledgeable with the legal boundaries, what the courts commonly find acceptable, and are familiar with court procedure and settlements. If a legal issue needs to be addressed in mediation, a family law attorney or mediator with a legal background like Ms. Keenan-Rivero is most suited for the task. Divorce and custody litigation carries an old stigma of two people battling it out in the courthouse. Not all cases take this course. In fact, many family law cases avoid the courtroom by reaching settlements through the mediation process.

Ms. Keenan-Rivero advocates for rational and pragmatic solutions to family law issues and helps clients pursue the appropriate legal method to obtain an amiable resolution or favorable outcome whether she is the attorney of record going to court, the attorney handling and attending mediation with her clients, or acting as the neutral third party mediator assisting parties in reaching settlement agreements.
