To simplify your experience in finding the right attorney, here is the intake process so you know what to expect when calling our office.

During the intake process, we run a conflict check to ensure we have not previously spoken with the other party in your matter. If we determine that there is no conflict, our case intake manager will go over our option of hourly billing or a tailored fixed pricing structure and the price range should the potential client choose to retain us hourly. While some clients may prefer to be billed hourly, our fixed pricing model may better align with your matter by offering personalized pricing structures and client participation in pricing decisions. Our price caps provide financial certainty, empowering you to make informed decisions while shifting the risk away from unpredictable costs.

Why Do I Need to Hire an Experienced Family Lawyer?
Do-it-yourself (DIY) family law services can be enticing, often offering low-cost alternatives that seem too good to be true. Unfortunately, that's usually because they are too good to be true.
Having a Family Lawyer at Your Side Throughout Your Legal Dispute:
- Makes dealing with paperwork easier. Various types of legal cases, such as divorces, require a substantial amount of paperwork. Relying on a lawyer to help you file your case with the court can help you confidently proceed with your case.
- Takes the legal burden off your shoulders. Working with an experienced family lawyer enables you to focus on your health and well-being while your attorney focuses on handling the legal side of your case.
- Helps you obtain a better long-term outcome. In legal disputes such as divorce, it can be easy to get caught up in the short-term, such as your ex's behavior or whether you want to "get back" at them in some way during the divorce. A lawyer will help you make decisions that safeguard your long-term happiness and stability.
- Ensures your rights remain protected. Unfortunately, it's not uncommon for family law disputes to turn ugly. Horror stories about family law cases where one party acted out of turn or attempted to handicap another legally are a dime-a-dozen. An experienced family lawyer will advocate for your rights and best interests in and out of the courtroom, giving you the protection you need.
- Paves the way towards an amicable outcome. A family lawyer can help you look at your case more objectively and work towards an amicable resolution for your case. Our firm can also use a form of alternative dispute resolution (ADR), such as mediation, to resolve family law disputes can help both parties save time, stress, and money on their case.
