How We Handle Family Law Matters

We Handle Every Type of
Family Law Situation

No two families are exactly alike. Whether you're facing divorce, child custody issues, support disputes, parenting plan modifications, prenuptial agreements, orders of protection, or other family law concerns, we help you understand your options and create a clear path forward.

What Does a Family Law Attorney Do?

Family law attorneys help individuals and families navigate legal matters involving divorce, child custody, child support, parenting plans, maintenance, adoption, prenuptial agreements, orders of protection, and other family-related issues.

When Should I Contact a Family Law Lawyer?

The earlier, the better. Many people wait until a situation becomes more complicated than necessary. Speaking with an attorney early can help you understand your rights, avoid costly mistakes, and make more informed decisions.

Can Family Law Matters Be Resolved Without Going to Court?

Often, yes. Many family law disputes are resolved through negotiation, mediation, collaborative processes, or settlement discussions. However, when agreements cannot be reached, court intervention may become necessary.

Here's How We Handle
Family Law Cases

Most people come to us feeling overwhelmed, uncertain, and unsure where to begin. Our process is designed to reduce confusion, provide clear answers, and help you make confident decisions throughout every stage of your case.

Working With Us

Here's What You Can Count On

Family law cases run long. The right working relationship matters as much as the right legal strategy. These are the standards we hold ourselves to, every day, from your first call through your final order.

Communication Standard

We respond to every client message within one business day, often the same day. When your attorney is in court, the team responds first so you always know we have heard you.

Who Makes The Decisions

We explain your options in plain English, give you our recommendation, and tell you the tradeoffs. We never settle, file a motion, or commit you to anything without your written authorization.

Billing Transparency

Every invoice is itemized so you see exactly what we did and what it cost. If a strategic choice will add meaningful cost, we tell you before we do the work.

Documentation Rhythm

After every hearing, negotiation, or strategic decision, you get a written summary of what happened, what was decided, and what comes next. You always have a record to re-read when the moment is calmer.

Reviews

Trusted During Difficult Times

Real clients on what it's like to have us in their corner.

"I have had the pleasure of knowing and working with Attorney Olivia St. Clair Long for almost a decade. I cannot say enough positive things about her as a person, how she practices law, and her character. I team up with her so I do not have to go against her, and her work is second to none! While Olivia will fight hard for her clients, she is also able to switch over to settlement mode with the same tenacity and in the interests of gaining the legal relief her clients request. Being in her field of law is quite emotional. I am impressed at how compassionate Olivia is with her clients, especially given the high stress matters she is retained therein"
"I had an excellent experience working with the team at O. Long Law, during a very challenging time in my life. The attorneys and paralegals were knowledgeable, compassionate, and always took the time to explain every step of the divorce process clearly. They handled my case with professionalism and made me feel confident that my best interests were being protected. Communication was consistent and timely, which helped reduce a lot of my stress. I would highly recommend this firm to anyone in need of reliable and supportive legal representation."
"Jessica was my representing attorney for my prenup. After being initially intimidated by the idea of a prenup, I felt comfortable talking with her. She is amazingly intelligent and personable. She went line-by-line through the draft prenup, explained everything to me, and made edits based on my feedback. She even thought ahead on things that I wouldn’t have even considered. I would recommend her to any of my friends needing representation."
"Olivia gave me advice in a high-conflict divorce situation - pro bono publico- and offered sound, clear and loving guidance. It was so clear to me that she is infinitely knowledgable and clear-headed. Strongly recommend. If you are part of a queer family, recommendation is even stronger, though I'm certain she'd represent everyone with care and honor."
