Lauren E. Walchli

Lauren’s family law practice focuses on divorce, custody, support, guardianships and adoptions.  She provides effective and, when necessary, aggressive legal representation to her clients, who include high-asset individuals and small-business owners. Clients often need the assistance of an expert to testify on their behalf, whether it be an accountant, an appraiser, a custody evaluator, or a social worker. In litigated cases, Lauren routinely utilizes these experts to her clients’ advantage.

Lauren also works with clients who wish to avoid litigation and resolve their cases collaboratively. Every client has a unique situation, and in many instances a cooperative approach to distribute the assets or work out a parenting plan is better tailored to a family’s needs than litigation in the court system. When you meet with Lauren, the two of you will discuss your particular case in detail and determine the best, most cost-effective method to resolve it.

Lauren is well-versed in the compensation packages of local technology companies, including complex assets such as restricted stock units, stock options, and stock appreciation rights, which many employees have.  Understanding of such assets is imperative to adequate representation in a divorce, and can save you significant amounts of money. If you are a divorce client and you have these kinds of assets, Lauren will advise you of the best method to divide these assets in order to equally allocate the risks of market gains and losses, as well as the tax impacts, between you and your spouse.

As a practitioner of consumer bankruptcy law, Lauren also routinely advises financially-distressed people and small businesses.

Do not let her hard-to-pronounce, Swiss last name fool you: Lauren is proficient in Spanish and has represented Spanish-speakers throughout her legal career.

Lauren is admitted to practice law in Oregon state and federal courts.

When she is not working, she paints and kickboxes. She has deep roots in the Pacific Northwest. In 1841, some of her Métis (part-Native, part-European Canadian) and European ancestors settled in what is now Washington County and Clark County, Washington. Her family also farms a variety of crops in Hermiston, including the notorious watermelons.
