About Hillary

Learn Hillary’s areas of practice.

Practice area

My practice focuses primarily on family law litigation, including complex marital dissolutions of high net worth estates that often involve business valuations and separate property tracing. I have broad experience with contested parenting matters, including establishing residential schedules and child support, as well as post-decree modifications of parenting plans, child support orders, and relocation actions. I also have experience litigating parentage cases and committed intimate relationship claims, as well as drafting, negotiating, enforcing and defending against prenuptial and postnuptial agreements.

Endorse Hillary
Litigation Attorney | Feb 18
Relationship: Co-worker
"I endorse this lawyer. Hillary has quickly developed an expertise in Washington civil litigation practice since moving here from Virginia, where she gained substantial civil litigation and employment law experience while working at a boutique civil litigation firm there for more than 10 years. As someone who practiced law for several years in another state before moving to Washington, I understand the challenges involved in starting anew. I appreciate how seamlessly Hillary has made the transition from Virginia to Washington practice. Hillary’s calm and thoughtful approach, combined with her strong advocacy skills, make her an outstanding choice for any potential client seeking a civil litigation or employment attorney."
