Divorce Information

Family Law Services Offered in Walnut Creek & Contra Costa County

The Walnut Creek Office provides a variety of different legal services designed to help those who need help with any subsection of family law. Some of the services include the following.

  • Divorce – If you’re thinking you want to get a divorce or your spouse has suggested a divorce, you need to know what to expect. The lawyers at the Walnut Creek law office can discuss your situation and give you personalized advice to help you move forward.
  • Child Custody and Child Support – Determining child custody and support can be complicated and stressful. Let the attorneys answer any questions you might have and provide the help you need to get the custody or support of your children figured out.
  • Property Division – Along with child support and custody decisions, property division can be extremely problematic during a divorce. Are you entitled to half of the home, even if your name isn’t on it? How are the savings accounts or other financial accounts going to be shared? The law firm can help answer all of these and any other questions you might have.
  • Financial Protection – Are you worried about how much child support you need to pay? Are you concerned you may be required to pay alimony? Let a lawyer from the Walnut Creek office discuss what could happen if you get divorced and how your finances may be split during the divorce.
  • Business and Family Law Issues – Business owners may be worried about their business if they divorce. Employees who have stock options as part of a start-up might worry about whether their spouse receives some of their stock in the divorce. The law firm has experience handling issues like these and can talk to you about what to expect.
  • Post-Divorce Assistance – Unfortunately, just because the divorce is final doesn’t mean your issues end. If you’re having trouble collecting alimony or child support, or if your spouse is not adhering to the divorce decree, you might have options. A lawyer will be able to let you know if anything can be done about the issues you’re having and, if so, what needs to be done for you to get the help you need.

No matter what issue you’re having, if it’s a family law topic, the law firm of Kaspar & Lugay in Walnut Creek can help you get the answers to questions you might have and can help you with any legal procedures that need to be accomplished. You can call them for a consultation to learn more about how they can help you.

Walnut Creek Divorce Attorneys

At Kaspar & Lugay, LLP, we provide families with effective solutions and staunch legal advocacy throughout the divorce process.

  • Divorce for Professionals. For those in positions that require professional certifications – attorneys, doctors, CPAs, etc. – there is often more at stake when it comes to divorce. Our skilled and financially savvy team (our founding partner is also a CPA, and our other partner has significant financial litigation experience) knows how to navigate the unique challenges of divorce for professionals.
  • High Asset Divorce. If you are a high earner or have a significant amount of wealth and assets (many people in the greater Bay Area do), it’s possible you’ll need a forensic accountant as well as the expertise and diligence of experienced attorneys who regularly deal with high asset divorce. Let our experience work to your benefit.
  • International Divorce. Whether you or your spouse moved for work, or for other reasons, international divorce can be quite complex and you’ll need somebody who is adept at understanding the nuance and scope of your unique situation.
  • Legal Separation. Many wonder what the “real” difference between separation and divorce is (tax implications, rights and responsibilities, etc.). Simply moving out of the house is not being legally separated. Learn what you can expect during this process.
  • Uncontested Divorce. Uncontested divorce means there is full alignment in terms of division of assets during a divorce. This is extremely rare where children and/or assets/property are involved. If this sounds like you, here’s some info that may help.
  • Out of State (Interstate) Divorce. Much like international divorce, those who live in separate states may be subject to inconsistent rules, procedures and protocol in different jurisdictions. Move-away orders can be complex, and our team has had incredible success in finding winning solutions for parents and children.

Walnut Creek & Contra Costa County Child Custody & Support Attorneys

A child’s best interests must remain at the forefront in any custody and support dispute. We tenaciously protect the rights of our clients and their children in child custody and visitation matters as well as child support proceedings.

  • Child Support ModificationsCalifornia child support orders are based on numerous factors, including both parents’ financial situations and circumstances at the time of their divorce. At Kaspar & Lugay, LLP, we understand circumstances change and our expertise allows us to assist you in seeking a modification to your existing child support order.
  • Custody & Care of Special Needs Children. At our family law firm, you will work with a lawyer who recognizes and understands all that you are going through as you seek a stable future for yourself and your special needs child.
  • Interstate Child Custody Disputes. Child custody is very often the most highly emotionally charged aspect of a divorce or separation. While our firm cannot promise to remove the painful dilemmas associated with an interstate or international child custody dispute, we can offer clear direction.

Walnut Creek Property & Asset Division Lawyers

In a high net worth divorce in Contra Costa County, as well as in households of more modest means, our attorneys draw on our experience in high-stakes litigation and our finance and tax backgrounds to obtain the most favorable property division settlement or judgment possible.

  • Startups: Early Employees, High Level Employees & RSUs. Startup founders going through divorce tend to face more complex issues during property division proceedings because their stake in the company could be worth a considerable amount of money or very little if the company fails.
  • Startups: Employees & RSUs/Equity. For employees going through divorce, understanding the vesting and distribution schedule of their RSU grant becomes incredibly important because these schedules not only determine when the employee is awarded equity, but how much that equity is worth.
  • Startups: Founders & RSUs. At Kaspar & Lugay LLP in Walnut Creek, California, we help startup founders and business owners alike handle the challenge of valuating and dividing community property, including RSUs, in divorce settlements.
  • Personal and Inherited Property in Divorce. We enter each California divorce case we handle with determination to understand every nuance and find the best strategic approach.

Our lawyers are accomplished in knowing how, and where, to look for hidden assets and hidden income in an asset search.

Client Testimonials

The best law firm for divorce in the bay area. Both Brent and Arvin are incredibly well versed in your rights and what is FAIR. They have gone out of their way to help me obtain a divorce from a very difficult situation. They were always professional, insightful and right on the money when it came to what you could expect. They held my hand through some of the more difficult areas and made sure I was well represented both in the courtroom and through many email exchanges with the defendant. I would highly recommend using them for both mediation (which mine started out as) and for full reprensentation. 


I was referred to Kaspar & Lugay law firm by a family member. From the first time I walked into their office, they have been very kind and courteous to me. I was primarily represented by Arvin Lugay in my divorce (and is currently ongoing) and don’t think I would have won my first case without him. He worked diligently day and night to make sure that we would be prepared in all our hearings. Arvin pays attention to every detail about the case and we both worked in a collective effort on the different strategies. He has helped me and family tremendously and I could not ask for a better lawyer than him. He is highly experienced and focuses on a really smart approach to every situation.”


Brent is the best attorney I have ever worked with. My complex divorce landed in the best, most capable hands you can imagine. Everything about my divorce became effortless- Brent is brilliant at handling all the details and guiding through with expertise. I had NO stress, which is hard to imagine in my situation. He is steady as a rock, knows his stuff, and is EXACTLY the person you want in your corner when you need an attorney.
