Jacob Koller is a member of Simmons Perrine Moyer Bergman. He practices primarily in the area of family law, which includes representing individuals in all aspects of domestic relations, including dissolution of marriage, child custody and visitation, child support, premarital agreements and related matters. In addition, Mr. Koller’s practice includes representing individuals in other circumstances affecting the family unit, such as adoption, guardianships and conservatorships.

Mr. Koller’s family law practice includes the following:

Mediation. Mediation, which is a form of alternative dispute resolution, has become an important component in resolving family law cases. Mr. Koller is a trained lawyer mediator, having completed a 40-hour training in 2009. As a mediator, he acts as a neutral to aid parties and their attorneys in settling their disputes without the need for court intervention.

Appellate Advocacy. In some cases, the decision of the trial judge is challenged on appeal. Mr. Koller has experience handling the prosecution and defense of appeals, both in cases for which the firm was trial counsel and in cases brought to him that have been tried by lawyers outside of our firm.

Litigation. Mr. Koller believes the best result in any family law matter is a negotiated settlement. When this is not possible, however, it becomes necessary to have a trial before a judge. Mr. Koller is experienced in the preparation and prosecution to trial of complex financial – including high net worth marital estates, large farm and livestock operations and business interests – and custody matters. He is a 2008 graduate of the American Family Law Trial Advocacy Institute, which is an advanced trial training program for attorneys specializing in the practice of family law.

Collaborative Law. Mr. Koller is trained in the practice of collaborative law and a founding member of the Collaborative Lawyers of Eastern Iowa. Collaborative Law is a non-adversarial process that views the issues arising from a divorce as a series of battles to be solved rather than fought. The end goal is to meet the legitimate needs of everyone involved in a restructured family. Both parties have independent lawyers present during negotiation to provide legal advice in an educational context, thereby empowering the clients to make informed decisions about their lives and their children’s lives. Mr. Koller is also a member of the International Academy of Collaborative Professionals.
