About Kylie

Kylie Costigan joined Estate First Lawyers in 2010 and is a Special Counsel. Kylie is a dedicated estate practitioner, having predominantly focussed from the outset of her career on the areas of estate planning law and estate administration law. She brings a rigorous and thorough approach to her work, yet still aims to make this often complex area of law accessible for her clients. She aims to clear any misunderstandings to ensure that clients’ affairs are structured in the best way to ensure a smooth transition of wealth from her clients to their intended beneficiaries.

Education & Credentials

Kylie is one of only thirty-eight Queensland Law Society Accredited Specialists in Succession law and a registered Trust and Estate Practitioner with the international organisation STEP (Society of Trust and Estate Practitioners). In 2019 Kylie was also one of the first Qld lawyers to receive her accreditation in Collaborative law in the estate planning field.

She holds a Bachelor of Laws with Honours from the University of Queensland and a Graduate Diploma in Practical Legal Education and Training from the University of Queensland.


Kylie has been practicing in the area of estates for over 15 years.

She enjoys a challenge and likes to find suitable and sometimes innovative solutions to the complex problems which our modern society causes in estate planning, especially for blended families, disabled and vulnerable beneficiaries and parents of young children. Kylie does this by preparing the right Will and the right structures supported by the right ancillary documentation.

Kylie also specialises in estate administration and has a particular interest in guiding and helping clients in this area as they deal with the grief process. Kylie brings the firm’s core values of professionalism combined with care to the forefront, assisting clients in navigating the myriad of tasks and compliance requirements involved in administering an estate on behalf of a passed loved one. Kylie is willing to assist her clients with both the big and the small things and to provide guidance and a human touch in this challenging time.

Kylie regularly presents on estate and succession-related topics to lawyers, financial advisers and accountants, including the QLD Law Society Succession Conference, the QLD Law Society Symposium Conference and LexisNexis Professional Development

"I can wholeheartedly recommend Estate First Lawyers. Kylie was very professional and friendly and explained any questions or concerns I had. The Estate First team were very efficient and courteous and it was a pleasure dealing with them."

"We made our appointment with Estate First Lawyers and began a journey of learning. Right from the start, our lawyer, Kylie, was friendly, confident, and most professional, putting us at ease and really personalising what she was explaining to our own situation. Every situation is unique and Kylie made us feel unique."



"I would like to thank you Kylie for your guidance and support throughout this lengthy and complicated process. I valued your professional advice and support around some of the tricky aspects of our family’s estate and appreciated the way you were able to keep us on track to complete and follow their wishes."
