Marte Timmers is a strong advocate and seasoned diplomat who specializes in helping high-net worth families to preserve their wealth by reaching resolution in even the most complex of cases.

For more than 20 years, Marte has been helping high-net worth families navigate both the financial and psychological challenges that arise when a divorce is on the horizon. Specializing in cases with $5+ million in assets, she has successfully resolved multiple cases with more than $100 million in assets. She understands the complexities of high-net worth cases involving trusts, closely held businesses, and significant tax implications, as well as the unique challenges that arise where generational wealth is concerned.

She is well versed in high-conflict business and financial disputes as well as parenting issues including difficult relocation cases, alienation, substance abuse, and mental illness. She understands the devastating effect that mental health issues can have on families and is knowledgeable about the support available to families with these issues. Marte also assists clients in drafting and reviewing marital agreements and cohabitation agreements.

Earlier in her career, she served as a judicial clerk for the United States Court of Appeals for the Fourth Circuit and as a magistrate judge in the Denver Juvenile Court. As a former magistrate judge, Marte is astute at anticipating both sides of a case and in predicting likely outcomes for cases that are decided under principles of equity. This ability to see all sides of a case gives her a leg up in effectively advocating for her clients in court and in assessing each case for settlement purposes.

An excellent listener, Marte is deeply committed to helping her clients reach resolutions that reflect their goals and values. She understands that out-of-court settlements provide clients with much more certainty and flexibility than court-decreed orders. While skilled in all aspects of litigation, she is also trained in collaborative law and is able to help parting spouses resolve matters amicably, avoiding costly and contentious litigation.

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.
