Representation for Property, Support, & Custody Disputes

A divorce may require decisions about finances, parenting, personal safety, or all three. We identify issues that need immediate attention, explain your options, and develop a practical strategy for negotiation or court.

Our divorce representation includes:

  • Complex property division: We address community property, real estate holdings, business valuations, separate property claims, and reimbursement disputes.
  • Income and support: We negotiate and litigate spousal and child support matters, including income calculations for self-employed spouses and corporate executives.
  • Child custody and visitation: We represent parents in disputes involving parenting schedules, decision-making authority, and contested move-away requests.
  • Domestic violence proceedings: We represent people seeking protection and those responding to allegations in domestic violence restraining order hearings.
  • Post-judgment changes: We handle requests to modify support or custody orders after significant financial or living changes.

Prepared for Mediation & Divorce Litigation

We prepare every case for both out-of-court mediation and full trial presentation. Settlement may provide greater control over the final terms, but it isn’t appropriate for every dispute. When court intervention becomes necessary, we prepare the evidence, testimony, financial records, and legal arguments the judge may consider.

Before entering legal practice, Mark Irwin spent nearly 30 years in law enforcement as an investigator. That background informs how we gather evidence, assess conflict, and evaluate credibility in sensitive divorce and domestic violence matters.

Our attorneys have also served as court-appointed Minors’ Counsel, representing children’s interests in family law cases. This work gives us practical insight into how courts examine custody arrangements, parenting plans, and the best interests of children.

Clear Billing & Direct Communication

Our billing agreements account for attorney hours, court filing fees, and administrative costs. We discuss anticipated legal steps and cost considerations directly, without a hard sell or unrealistic promises. Our attorneys also maintain active memberships in the Orange County Bar Association Family Law Section and local advocacy foundations.
