Marital Dissolution
A divorce decides how a family's life is restructured: who the children live with, how property built over years is divided, and what support looks like going forward. We represent spouses through dissolution and the disputes that follow, with particular depth where a closely held business, real estate, or significant assets are on the table.

Divorce and marital dissolution lawyers for Bellevue and Seattle families
Oseran Hahn represents spouses in dissolution and the family-law disputes that surround it. Washington is a no-fault, community-property state, which shapes everything: property acquired during the marriage is generally divided in a way the court considers just and equitable, support follows statutory factors, and parenting is decided by the children's best interests. We handle the division of property and debt, spousal maintenance, child support and parenting plans, and the relocation and modification fights that come later, with real strength in divorces involving a business or complex assets.
A dissolution is the legal unwinding of a marriage, and in Washington the law sets the framework while the facts decide the outcome. We litigate the division of community and separate property, the part of a divorce that often matters most. We handle spousal maintenance, both pursuing and defending it under the statutory factors. We build and contest parenting plans and child support, where the children's best interests govern. We bring particular depth to divorces involving a closely held business or significant assets. And we handle the relocation, modification, and enforcement disputes that arise long after the decree is entered.
Dividing property and debt
In most divorces the hardest fights are about money and property. Washington is a community-property state, so assets and debts acquired during the marriage generally belong to both spouses, while property owned before the marriage or received by gift or inheritance is usually separate, and the court divides everything in the proportions it finds just and equitable (RCW 26.09.080 and RCW 26.16). The work is in the characterization: tracing separate property that's been commingled, valuing a home, a retirement account, or a business, and accounting for one spouse's contributions or waste. We build the financial picture carefully, because how property is characterized and valued usually drives the entire result.
Spousal maintenance
Maintenance, what many still call alimony, is one of the least predictable parts of a Washington divorce, because the statute lists factors rather than a formula (RCW 26.09.090). Courts weigh the length of the marriage, each spouse's financial resources and earning capacity, the standard of living established during the marriage, and the time one spouse may need to become self-supporting, among others. The result can range from nothing to long-term support after a lengthy marriage. We pursue maintenance for a spouse who needs it and contest unwarranted or excessive claims for the one who would pay, and we frame the request around the factors a court actually applies.
Parenting plans and child support
When children are involved, the parenting plan is the heart of the case. Washington requires a plan that sets the residential schedule, allocates decision-making, and provides for resolving future disputes, all measured against the children's best interests (RCW 26.09.187). Child support is more structured, calculated from both parents' incomes under the statewide support schedule (RCW 26.19), though deviations and the treatment of variable or self-employment income leave plenty to litigate. We work to build parenting plans that hold up and reflect the children's actual lives, and we get the support calculation right, because errors in income or credits compound month after month.
Divorce involving a business or complex assets
Divorces involving a closely held business, professional practice, or significant assets are their own kind of case, and they're where our firm's depth shows. We handle the valuation of a business or professional practice, the division or buyout of an ownership interest without wrecking the company, the tracing of separate and community contributions to an asset, and the treatment of executive compensation, stock, and deferred income. Our business and real estate lawyers work alongside the family-law team, so the valuation and the deal structure are handled by people who do that work daily. For a business owner, protecting the enterprise through a divorce is often as important as the division itself.
Relocation, modification, and enforcement
A divorce decree is rarely the end of the matter, because lives change. We litigate relocation cases when one parent wants to move with the children, which Washington governs through a specific notice-and-objection process and its own set of factors (RCW 26.09.405 through .560). We handle modifications of support, maintenance, and parenting plans when circumstances shift substantially (RCW 26.09.170 and RCW 26.09.260), and we enforce orders through contempt when the other side won't comply. We also litigate the enforceability of prenuptial and postnuptial agreements, which our estate-planning group drafts, when a marriage that had one comes apart.
Sixty years counseling Pacific Northwest families and business owners, with a family-law practice that handles divorce with discretion and a firm-wide bench that brings real depth to the business and property questions a high-asset divorce turns on. We work to resolve these cases without needless conflict, and we litigate hard when the other side or the stakes require it.
We bring business depth to divorce.
When a closely held company or complex assets are in play, valuation and structure decide the outcome. Our business and real estate lawyers work the case with the family-law team, which most family-law firms can't offer.
We resolve without scorching the earth.
Most divorces should settle, and dragging children and finances through a trial rarely serves anyone. We negotiate firmly toward a fair resolution, and we keep the courtroom ready for the cases that genuinely need it.
We handle the matters that come after.
Relocation, modification, and enforcement disputes surface for years after a decree. We know the file and the history, so we can move quickly when life changes and the orders need to change with it.

What clientsask us first.
How is property divided in a Washington divorce?
Washington is a community-property state, so most assets and debts acquired during the marriage are owned by both spouses and subject to division, while property you owned before the marriage or received by gift or inheritance is generally separate. The court divides everything in the way it finds just and equitable, which is not always fifty-fifty (RCW 26.09.080). Much of the fight is over characterization and value: tracing separate property, valuing a home or business, and accounting for contributions, which is where careful financial work changes the outcome.
Will I have to pay, or can I receive, spousal maintenance?
It depends on the factors, because Washington has no maintenance formula. Courts weigh the length of the marriage, each spouse's resources and earning capacity, the standard of living during the marriage, and the time needed to become self-supporting (RCW 26.09.090). A long marriage with a large income gap is the strongest case for substantial maintenance; a short one between two earners may produce none. We assess where your facts fall and build the case for or against support around the factors a judge actually applies.
How are parenting plans and child support decided?
The parenting plan sets where the children live, how decisions get made, and how disputes are resolved, all based on the children's best interests (RCW 26.09.187). Child support is calculated from both parents' incomes using Washington's statewide schedule (RCW 26.19), with room to argue over income, especially self-employment income, and deviations. We focus on building a parenting plan that reflects your children's real lives and getting the support numbers right, because small errors in income or credits add up significantly over time.
I own a business. What happens to it in a divorce?
It becomes one of the central questions, and how it's handled matters enormously. The business has to be valued, its community and separate components traced, and then divided, usually by awarding it to the owner-spouse and offsetting the other spouse's share with other assets or a structured payment rather than splitting ownership. This is where our firm's business and real estate experience matters: we value and structure the outcome to protect the company's operations while treating both spouses fairly. Protecting the enterprise through the divorce is often as important as the dollar division.
Can I move out of the area with my children after divorce?
Maybe, but Washington has a specific relocation process you must follow. The relocating parent has to give formal notice, and the other parent can object, after which the court weighs a defined set of factors centered on the children's interests and the effect of the move (RCW 26.09.405 through .560). Relocation is one of the most contested areas of family law, and the outcome is fact-specific. Whether you're seeking to move or opposing a move, the notice requirements and timing are strict, so it's important to involve a lawyer early.
We have a prenup. Does it control the divorce?
Often, but not automatically. Washington enforces prenuptial and postnuptial agreements, but only if they are both substantively fair and were entered into fairly, with full disclosure and a real opportunity to understand them, under the standards drawn from cases like Bernard. A one-sided agreement signed without disclosure or counsel can be set aside. We assess whether your agreement holds up, enforce it where it does, and challenge it where it doesn't, coordinating with the estate-planning group that handles these agreements on the front end.
