Naomi de Costa is a Special Counsel and the Queensland leader of Maurice Blackburn’s Wills and Estates Law practice area. She is a Queensland Law Society Succession Law Accredited Specialist and trust and estate lawyer who is based in Cairns and sees clients in all of the firm’s Queensland offices of Brisbane, Browns Plains, Caboolture, Gold Coast, Ipswich, Mackay, Rockhampton, Strathpine, Sunshine Coast, Townsville and Toowoomba. The prestigious Doyles Guide lists Naomi as a recommended Wills litigation lawyer in Queensland.

Naomi has 10 years’ experience in Will and estate law, and acts for clients in Will disputes matters in the areas of family provision, enduring powers of attorney and statutory Wills. A passionate and driven lawyer, who likes working closely with clients to achieve the best result for them, Naomi is justifiably proud of her ability to combine technical expertise with straightforward and plain spoken advice to her clients.

“Succession law is a technical area of the law, but one that affects everyday people. I enjoy the challenge of being able to find the right legal solution to fit the complex situations of each family and the disputes that can arise as a result. I try to communicate with my clients in plain English, even in circumstances where their matter might be difficult or complicated,” says Naomi.

Naomi’s depth of experience in Wills and estates law shows itself in a number of areas: from her ability to quickly provide clear and accurate advice, to her understanding of and compassion for the family disputes and dynamics that so often go hand in hand with a Will dispute. She is also aware of client confidentiality and most of her cases settle without the need to go to court.

“Will disputes is an area that a lot of legal practitioners dabble in – I’m proud to be an accredited specialist, with a decade of experience in Will disputes under my belt.

“I also practiced for many years in estate planning, including Will drafting. I think that experience is very useful in Will disputes – an understanding of the nature and process of Will drafting is integral in being able to advise on how any Will dispute should be approached.”

In any dispute, Naomi is determined that all parties should be treated fairly and with respect, while remaining committed to finding solutions to any injustice experienced by her client.

“Wills disputes can be pretty challenging as usually the litigants involved are parents and their children, or brothers and sisters. Every so often, we are involved in settling a Will disputes matter where the parties can heal their relationships once the dispute is over. That can’t always be done, but I think it’s important to always remember that Will disputes aren’t just about law – they’re about people. In finding a solution to Will disputes we need to look at the whole picture, rather than just a set of papers.”
