Protecting Your Rights & Advocating For Your Interests

High Net Worth Divorce Attorney

Helping You Protect What You Value Most

Gavin Halligan

The Right Representation Matters

When executives, entrepreneurs, business owners and other high net worth individuals divorce, immediate attention is required. These matters involve multifaceted, diverse, high (and frequently hard to value) assets and income streams.

High Asset Divorce requires legal experience beyond dealing with the ‘typical’ divorce case because of its complexity. 

Attorneys who deal with high net worth divorces must thoroughly understand the many issues surrounding business valuation, complex alternative investments, multiple trusts, overseas accounts and holdings, real estate, taxes, inheritance, retirement benefits, stock options, and the possible effects of prenuptial agreements.

On Your Side Every Step Of The Way

The stakes are high in High Asset Divorce and the outcomes can have immense, long lasting impacts on quality of life, distribution of assets, support, and more – for years. Perhaps for generations.

Halligan LLC has the experience needed to handle the complexities of High Asset Divorce. We also have a long history of working successfully with professionals – our own and our clients’ – in business valuation, business and estate planning, and more that uniquely places us in position to help our clients through the most overwhelming financial issues.

What Our Clients Say About Us


Gavin was always available and had a complete grasp of the process. She was thorough and understood the finer points of the law such that she stayed one step ahead of opposing counsel.

Michael on Avvo


Ms. Halligan and her team did an outstanding job representing me during my divorce. I give them my highest possible recommendation. My divorce had some complicating factors including children, a variety of assets types, and partial ownership of a business which needed to be addressed. Gavin and her team were always knowledgeable and prepared for every step in the process. They were also personable and empathetic which made me feel like they really understood my concerns and priorities while professionally steering me to make decisions that were in my long term best interest.

Karl on Avvo


Divorce and custody battles are exhausting and unfamiliar territory for first time divorcees! After having fired 2 other attorneys who I felt were not representing my interests, I found Gavin Halligan. Gavin has been a game changer for me. Gavin Halligan listens, offers sound advice, always returns my calls/emails, and most importantly, represents ME. Gavin has fought hard for my custody rights and has helped me gain the custody I so desperately desired. As a father, you already start in the negative for child custody during a divorce. You must have a strong attorney who knows the law and the system to gain the custody you desire for the relationship you deserve as a parent. Gavin Halligan will help you through this troubling time and make sure your rights are not lost in unnecessary compromises. Gavin’s expertise, professionalism, and strong representation of my interests gave me hope that I would achieve my parenting rights as a father. She continues to help me gain valuable time with my child and I can’t thank her enough for that! I highly recommend Gavin Halligan if you are looking for representation during a divorce or child custody battle.

Help With Every Aspect of Your Divorce

If you have children, the allocation of parental responsibilities and child support are centrally important. We understand how the Uniform Child Custody Jurisdiction and Enforcement Act (UCCJEA) impacts child custody jurisdiction. We also specialize in multi-jurisdictional litigation for divorce and custody, which can happen when a spouse lives in one state but must go through divorce litigation in a different state.

Because different jurisdictions may have different laws about custody, child support, and other aspects of divorce, a knowledgeable and effective attorney is crucial to ensure your and your children’s interests are fully and fairly represented.

Colorado is an equitable division state and the court will divide the marital estate according to equity principles. “Equitable” is not the same as “equal.” When determining how to divide marital property, the court will take into consideration all relevant factors, such as the economic circumstances of each spouse at the time of dividing the property, the contribution of a spouse as a homemaker, the value of each spouse’s separate property, any increases or decreases in this property, and depletion of separate property.

When a married couple decides to separate or to seek a divorce, the law provides a mechanism for both spouses to continue to enjoy a similar standard of living as they begin their new lives apart from one another. This is especially important when spouses have vastly different income and financial resources, so that one spouse is not unfairly burdened by a reduction in his or her standard of living just because his or her marriage has ended.

Divorce cases involving complex, diverse, or high-value assets and income, including businesses, trusts, separate property, and hidden assets, can be very complicated and require expert guidance. Retirement accounts, offshore bank accounts, royalties, deferred compensation, bonuses, inheritances, and gifts can add another layer of complexity. We are also experienced with receiverships, which is an extremely rare but sometimes necessary process when a party is hiding or dissipating assets.

Our firm has extensive experience working with high-asset divorce and out-of-state divorce issues. Divorce is a challenging experience for everyone, those involved in high-asset divorces face additional complexities in protecting assets, dividing businesses, and much more. Professional and entrepreneurs, of course, face the same challenges.

Out-of-state divorce, of course, adds layers of complications. Out-of-state divorce and custody cases are difficult, factually complex, and often emotionally volatile. We can and will take you through all the ramifications.

Growing a company can be profoundly challenging, even when your family is intact and your spouse is behind you. Divorce makes the entrepreneurial journey even more fraught. Our family law team has substantial experience leading business owners through the divorce process. We can help you get the clarity you need and ensure a fair outcome.

Client Testimonials

    I am so thankful to have had Gavin, Laura, and the rest of Halligan LLC in my corner during a very difficult process. At the end of the day, I can honestly say that I got almost everything I desired including a great parenting plan that will allow me to have as much time with my son as possible.

    I give them my highest possible recommendation. My divorce had some complicating factors including children, a variety of asset types, and partial ownership of a business which needed to be addressed. Gavin and her team were always knowledgeable and prepared for every step in the process.

    Simply put, Gavin made my ex-wife's lawyer look like a guy who got his degree from a mail order catalog! Though he supposedly had been in practice for 30 years, Gavin mopped the floor with him! She countered every demand that my ex and her lawyer made with law that backed my position and she gave me awesome advice on how to respond to their attempts at extortion. In the end, my ex ended up with less than she had before she got greedy.
