Executors and Estate Administration – Are Trust Companies a good option?
Choosing an executor is a critical decision. Before choosing who should manage your estate when you die the most important task is to ask if the person contemplated is up to the job. The ideal executor will follow your wishes, know how to administer the estate, be honest and fair, and be prepared to do the job in a timely and proper fashion.

Can a Non-Resident Apply for Probate?
Section 5 of the Estates Act (the “Act”) states “Letters of Administration shall not be granted to a person not residing in Ontario”. The statute appears to be a definite and full answer to our question. But, when answering a legal question, a thorough reading of the statutes and secondary sources dealing with the question together with a full review of how judges interpret the statute is necessary. As the Armstrong case demonstrates, reading only one section of the Act could lead to an erroneous conclusion.

I contacted Mr Wagner for assistance in drafting a will. Despite the fact that Mr Wagner is a Litigator and does not draft wills, he took the time to introduce me to another lawyer. During that conference call , he provided us with extremely valuable advice to avoid future litigation. I greatly appreciate the time and expertise that he provided free of charge. Thank you again Mr Wagner

Our estate case was being handled by the firm. Brad Phillips was thorough in his investigation and Charles Wagner gave us direction through the case. The team handling our case - Brad & Aaron, were insightful, thoughtful and hardworking for the entire duration. I believe that they genuinely felt empathetic towards our case.

March 20, 2019 after contemplating making this call for many weeks I finally contacted Wagner Sidlofsky seeking advice on how to proceed with obtaining a copy of my fathers will. When I called the receptionist who was very pleasant, asked for some information and told me I would receive a call as soon as someone was available. Within 30 minutes I had the pleasure of speaking to Mr. Charles Wagner. I explained what I was after and throughout our conversation he asked questions of me that I really hadn't thought about. I appreciated the time he took to give me food for thought excellent advice. Mr. Wagners' compassion, professionalism and honesty is very much appreciated. Consoling someone crying on the phone, who he had never met. I am so glad I made the call to this law firm and I am grateful for the conversation that I had with Mr. Wagner.I would definitely contact this law firm again should I require any legal services.Thank you Charles Wagner. You made sense of it all.Kind RegardsJoanne
