Halligan LLC

Halligan LLC is a Denver firm that practices family law and nothing else, with Gavin Halligan leading alongside Timothy Dudley, Ethan Sumida and Chip Dunn.

The work covers divorce, including higher net worth and business-owner cases, common-law marriage, later-life divorce, division of property where the assets are hard to value or hard to find, child support and custody, interstate and multistate custody, marital agreements, post-decree modifications, temporary and emergency orders, and appeals.

Colorado's recognition of common-law marriage makes that first item more consequential for same-sex couples than it sounds. Couples who lived as married before 2015 can have their relationship recognized as beginning earlier than any license, which changes what counts as marital property and how long the marriage is treated as having lasted. The firm says it is committed to guidance that respects your identity and values your family, and it handles interstate matters, which matters when a family has moved between states whose recognition rules differed at the time.

Billing is issued twice monthly with itemised descriptions, and the firm is explicit that it litigates when a situation calls for it and applies judgment about when aggression would be counterproductive.
