“I cannot thank Jeremy Duffy enough for the amount of time, effort and detail he went into assisting me with my contested estate matter. The fact that I had to move interstate and work with someone long distance worried me initially, but Jeremy Duffy has proudly adopted being able to work digitally long distance, which made life a lot easier. I could continue living day to day with the confidence that Jeremy was looking after the estate matters in the background. I would not be where I am today if it was not for his assistance and I give my highest recommendation.”

Nigel Fredericks, ACT

“Jeremy was engaged review a share buy back agreement to ensure compliance with the Corporations Act and Australian Taxation Office requirements. Jeremy was thorough and through consulting with other specialist colleagues clearly highlighted many significant shortcomings and potential issues in the original document. Jeremy then reauthored the agreement to not only address the shortcomings but also to ensure that the document was clearly ordered and fit for purpose. Jeremy was responsive and completed the assignment under significant time pressures. Jeremy’s work was accepted without changes by the other parties. I would highly recommend Jeremy.” 

Vic Koehn, Qld

“My wife and I have instructed Jeremy Duffy on a number of occasions over the years with respect to wills and other estate planning matters. Most recently, I instructed Jeremy with respect to my wife’s estate, which involved successfully resolving a potential dispute, dealing with difficult superannuation issues and obtaining probate. I have always found Jeremy to be very efficient, responsive and effective. I can highly recommend Jeremy Duffy to anybody requiring estate planning services.”
