Marte Timmers has been practicing law for more than 20 years and focusing on family law for more than a decade. She is a former juvenile court magistrate judge appointed by the chief presiding judge for the Denver Juvenile Court.

In that role, Marte presided over child support enforcement and parenting time cases, contempt matters, and some adoptions. As a result, Marte knows firsthand how the bench may view a case and how to advocate effectively for her clients. That rare perspective and experience prove invaluable in building the strongest cases for her clients and in helping them navigate litigation matters and all aspects of the court process. Marte also served as a judicial clerk for the United States Court of Appeals for the Fourth Circuit. In these roles, she gained clear insight into the judicial process and how best to argue on her clients’ behalf.

While skilled in all aspects of litigation, Marte is also trained in collaborative law and is able to help parting spouses resolve matters amicably, avoiding costly and contentious litigation. A savvy, skilled negotiator, Marte also has a strong record of achieving favorable settlements for clients through mediation.

She is well versed in high conflict business and financial disputes as well as parenting issues including difficult relocation cases, alienation, and substance abuse and mental illness and their effect on families. She also assists clients in drafting and reviewing marital agreements and cohabitation agreements. Marte’s ability to connect with people along with her skill in resolving complicated business, tax, and trust-related disputes enables her to help people in all aspects of their legal processes.

Over the course of her career, Marte has established effective working relationships with the mental health community and a wide variety of experts including business valuation experts, accountants, and parental responsibility evaluators in Colorado.

Clients truly appreciate Marte’s compassion and sensitivity in handling family matters and the fact that she is always available to them to answer questions, address their concerns, and creatively strategize to resolve family issues.
