The work of a family law firm

• Divorce and dissolution of marriage
• Child custody, parenting time and child support
• Division of complex marital and community property
• Spousal maintenance
• Mediation and alternative dispute resolution
• Estate planning

Family law is among the most personal areas of legal practice, requiring not only technical skill but also judgement, discretion and sensitivity. Arizona is a community property state, meaning that property acquired during a marriage is generally owned jointly, which makes the division of assets in a divorce a particularly important and sometimes intricate exercise, especially where business interests, investments or significant estates are involved. Experienced counsel helps clients understand their rights, protect their interests and, where possible, reach resolutions that reduce conflict and cost. When litigation is unavoidable, seasoned trial lawyers are essential to presenting a client's case effectively before the court.

The firm's combination of trial experience and dispute resolution capability allows it to tailor its approach to each client's circumstances, pursuing settlement or mediation where appropriate while remaining fully prepared to advocate in the courtroom. This flexibility is especially valuable in high-conflict or high-value matters, where the stakes for families and their finances are considerable.

The financial dimension of family law deserves particular emphasis. In cases involving business interests, professional practices, retirement assets, real estate and other substantial holdings, the accurate identification, valuation and division of property can be as demanding as any commercial dispute. Experienced family lawyers work closely with financial and valuation experts to ensure that a client's interests are properly protected and that settlements or judgments reflect the true value of the marital estate. This depth is a hallmark of a leading family law practice, and it is central to the reputation that Karp & Manzi, PLC has established in Arizona.
