Tannis Arnold

I am Tannis Arnold, co-director and founder of West Coast Legal, a Perth-based family law firm. I completed a Bachelor of Laws degree at Notre Dame University in Western Australia. I have also worked for Legal Aid Western Australia and completed a clerkship at the Office of the Director of Public Prosecutions. Prior to practicing law, I worked with families and children in the education industry. I have a Diploma of Teaching and a Bachelor of Education Degree. This expertise compliments my skills when working within the area of Family Law. I have experience with cases ranging from complex property settlements for married and de facto couples and proceedings concerning the care of children as well as divorce and child support issues. When not working my interests include promoting justice within the community through voluntary work and spending time with my family.

Teresa Sutherland

I’m Teresa Sutherland, co-principal and director of West Coast Legal, one of the leading boutique Family Law firms in Perth. I have a Bachelor of Laws degree from South Africa and was admitted to the Supreme Court of Western Australia in February 2016, after I completed my Bachelor of Laws equivalence studies at Edith Cowan University. I joined West Coast Legal in February 2016. Since my admission, I have practiced exclusively in Family Law and accrued extensive experience in all areas of Family Law, with a particular interest in both simple and complex property settlement matters. I am passionate about resolving my clients’ matters in a supportive and collaborative manner to ensure efficiency and effectiveness. Family Law can be stressful and that is why I believe in partnering with my client to resolve their matter with compassion and diligence. I focus on mediation rather than litigation as it is more cost effective and less stressful. However, should a matter call for it and require Court intervention, I will be right there alongside you. In my spare time, I enjoy volunteering and giving back to the community and spending quality time with family, friends and my Labrador, Bailey.

I have seen Tannis several times for legal advice for the last 2 years. Until early this year I finally decided to go through with my legal separation.

Tannis was so understanding and accommodating. During this emotional and stressful process she made it easy for me. I highly recommend Tannis and the team.
