Unparalleled Legal Expertise for Business Owners at Halligan LLC

As a business owner going through a divorce in Colorado, I found myself in need of a family law attorney who could navigate the complexities of my case with an astute understanding of both family law and business ownership. Gavin Halligan and the team at Halligan LLC exceeded all my expectations. ...Gavin demonstrated an impressive depth of knowledge specific to Colorado divorce law, particularly as it pertains to the division of assets and businesses. She was able to meticulously dissect the intricate web of my business finances to ensure a fair division of assets. Her understanding of the interplay between business ownership and divorce law was, quite frankly, remarkable. Throughout the process, Gavin's communication was consistently clear, straightforward, and tailored to my understanding. She took the time to explain the legal jargon and ensured I was fully aware of all potential outcomes. Her strategic approach and expert negotiation skills allowed us to avoid a lengthy and expensive trial, for which I am extremely grateful. Every interaction I had with the team at Halligan LLC was a testament to their professionalism and efficiency. They made the process as seamless as possible, constantly keeping me informed about my case. Gavin Halligan's expertise is evident in her mastery of both family law and the specific challenges that come with business ownership in a divorce setting. I wholeheartedly recommend her services to anyone in a similar situation. Her five-star performance made a difficult process significantly easier for me, and I am certain she will do the same for others.

Extremely happy in all phases of my divorce. Available when needed and always polite. Took the time to answer all my questions and most importantly always listened.

Amazing Service!

Gavin and her team took on my divorce and custody jurisdiction case at the last minute right before Christmas. They were attentive, helpful, and responded to every email and concern I had being that I was out of state. And when I tell you I was losing my mind, I was losing it. They were patient with ...me and calmed me down while helping me get my paperwork in order to ensure I was doing things the right way. Their diligence and dedication to learning my case allowed them to understand my situation from every angle. Ben (the lawyer assigned to my case) was professional and very hands on. He was invested in helping me and his tenacity to ensure the court understood my situation showed throughout the entire process. Their honesty and transparency allowed for me to consider all possible outcomes, but still gave me hope because they worked as hard as they could for my children and I. In the end, they were able to win my case in Colorado and jurisdiction remained in my home state. I recommend Halligan LLC to anyone that wants to feel like more than just a client. Gavin and her team make me feel like I am now part of their family. Thank you!!! A million times!

Gavin Halligan will represent YOUR interests

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.

Relationship: Supervised lawyer

"I hired Gavin less than a year ago to join The Burnham Law Firm. In that short time frame, she has become an indispensable asset to the firm. She is an exceptional strategist who is passionate about her clients and their children. Her work product (not just effort), her exceptional mind and focused drive required me to make her the firm's Senior Associate with managerial responsibilities and will be the attorney overseeing the Denver office when that permanent location opens in the Fall of 2014. Bottom line: When Gavin is on a case, everything is covered, nothing the opposing party does can be hidden, and her tenacity is underscored only by her professionalism and commitment to be great."
