About
Heather C. McAllister is a family law attorney in Houma, Louisiana, who represents clients in divorce, custody, spousal support, child support, and community property matters. Her practice is shaped by experience with child support enforcement, family court concerns, and the practical issues that affect parents, spouses, and children during major life changes. She works with clients who need guidance through difficult domestic matters, including support disputes, parenting arrangements, and property-related issues connected to divorce.
Ms. McAllister graduated with High Distinction from the University of Michigan, where she received Class Honors and became a member of the Golden Key National Honor Society. She earned her J.D. from the University of Georgia School of Law in Athens. During law school, she interned with the British House of Commons in London and with the United States Trade Representative in Washington, D.C., gaining exposure to legal and governmental work beyond traditional classroom study.
Ms. McAllister later worked as a prosecutor in Cuyahoga County’s Child Support Enforcement Unit in Cleveland, Ohio. In that role, she helped locate absentee parents, establish paternity, secure child support orders, and manage enforcement proceedings. That background gives her useful insight into support-related cases and the procedures families may face when financial responsibilities, parental rights, and court orders become contested. Her work in family law reflects careful preparation and attention to the facts behind each client’s situation.
Heather C. McAllister is active in the Terrebonne Parish legal community and participated in Leadership Terrebonne Class of 2010. She has served as a representative to the Louisiana State Bar Association House of Delegates and as a board member for South Louisiana Legal Services. She also maintains membership in the Louisiana State Bar, the Terrebonne Bar Association, and the Lafourche Bar Association, with inactive memberships in Ohio and Georgia.
