Irwin & Irwin is a family law firm based in Fullerton, California. We handle complex divorce cases involving businesses, retirement accounts, real estate, separate property claims, reimbursement issues, and long-term support concerns. Our attorneys are licensed to practice law in California, and our work is focused exclusively on family law.
Family law matters are deeply personal. Divorce, child custody, support, domestic violence restraining orders, and property division can affect nearly every part of a person’s life. We understand that our clients often come to us during one of the most stressful chapters they have faced. Our role is to provide clear guidance, honest advice, and strong advocacy from the first consultation through resolution.
With nearly 50 years of combined experience, our team brings practical legal knowledge, courtroom preparation, and compassion to every case we accept.
Irwin & Irwin was founded by Mark Irwin and Kelly Irwin. As husband and wife, they built the firm with a shared commitment to helping families move through difficult legal matters with dignity and direction.
Mark Irwin is a former police officer. That background gives him a practical understanding of conflict, safety concerns, family crisis situations, and the importance of preparation. Kelly Irwin brings thoughtful legal guidance and a client-centered approach to complex family law issues. Together, they lead a firm that values honesty, communication, and careful case strategy.
We do not believe clients should be left guessing about the legal process. We explain what is happening, what options may be available, and what risks should be considered before major decisions are made.
Every family law case is different. Some matters can be resolved through negotiation or mediation. Others require strong courtroom advocacy. We prepare each case with both possibilities in mind.
When settlement is appropriate, we work to resolve disputes efficiently and with as little stress as possible. When court involvement is necessary, we are prepared to advocate for our client’s rights and position before the judge.
Our approach is straightforward:
No attorney can promise an outcome. What we can do is bring preparation, experience, and steady guidance to the process.
Our firm assists clients with a wide range of California family law matters, including:
