Denver Divorce And Family Law Lawyers

On Your Side Every Step Of The way

Crossing a Bridge
Getting a divorce can be a scary and frustrating process filled with uncertainty and doubt. No one gets married with the expectation that they will one day want a divorce, but the reality is that many marriages ultimately end in divorce.

In some cases both spouses will jointly come to the realization that their relationship is over and they need to seek legal services to pursue a divorce. In other cases, one spouse may want out of the marriage and may start the legal process to initiate a divorce case. And in other cases, a spouse may notice changes in his or her other spouse and their relationship that causes that spouse to want to explore his or her rights and options.

No matter what circumstances you find yourself in, we’re here to help. Our experienced Denver divorce lawyers can answer all the questions you may have about divorce in Colorado and guide you through all the issues that must be resolved in a divorce proceeding, including property division, alimony/spousal support, child custody/child support, and more.
Testimonials from Previous Clients

What our customers say about us

  • "I give them my highest possible recommendation."
    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.
  • "...she stood up when I was being advised by a different attorney to roll over and accept defeat"
    I'm so extremely grateful to Gavin. During an extremely discouraging custody battle, she stood up when I was being advised by a different attorney to roll over and accept defeat. The truth was there, and she beautifully presented the logical truth. Additionally, she personally ensured (due to multiple state involvement) my other lawyer was well versed in the situation to ensure no further manipulation to a long battle would happen. Absolutely 5/5 stars.

  • "Excellent Divorce Attorney"
    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.
  • "Very happy client"
    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.

Denver Divorce FAQ

How is property divided in Colorado divorce?
Property division in divorce, also known as equitable division, refers to the aspect of a divorce proceeding in which the court will divide a couple’s marital assets and liabilities. Equitable division does not mean equal division, only that assets and liabilities are fairly divided between spouses. We can help ensure that you receive a fair equitable distribution in your divorce, including securing marital assets that may hold significance to you, and protecting assets that qualify as separate property and therefore are not subject to equitable distribution.

How does alimony/spousal support work in Colorado divorce?
Alimony or spousal support refers to the payments that one spouse makes to another during and following divorce to help the recipient spouse pay for his or her living expenses, usually until such time as that spouse can become self-sufficient following divorce. If your spouse has been the breadwinner in your family, we will fight to make sure that you are not left without any means of support in the event you and your spouse get divorced.

How do parental responsibility (child custody) and child support work in Colorado?
If you and your spouse have children, the issues of child custody (now called “parental responsibility” in Colorado) and child support often become some of the most vigorously contested issues in divorce. Our experienced attorneys have a deep understanding of the state and federal laws governing matters of parental responsibilities and child support. We’ve also helped clients through multi-jurisdictional litigation for custody and support matters, where one spouse/parent has moved from Colorado and now lives in another state. Our firm will always look out for your and your children’s rights and interests.
