The neighbourhood

Duensing Law's office is at 393 University Avenue, Suite 2000, on University Avenue in downtown Toronto. The building itself served as a Superior Court of Justice location until January 2020, when the court's civil operations moved to 330 University Avenue and its criminal and family matters moved to 361 University Avenue, both close by. Estate matters are now heard alongside the court's bankruptcy and commercial lists on the 9th floor at 330 University, a short walk from the firm's door, which is a useful proximity for a practice built around estate litigation and probate administration.

Frequently asked questions

Does Duensing Law prepare wills and powers of attorney?
Yes. The firm drafts wills, powers of attorney, and trusts, and reviews and updates existing wills, tailoring the documents to each client's circumstances rather than working from a generic template.
Can Duensing Law help if family members are disputing a will or an estate?
Its estate litigation practice covers will and estate disputes, including questions of validity, undue influence, and capacity, along with dependant support claims, fiduciary accounting, and applications to remove an executor.
Does Duensing Law handle real estate closings in Toronto?
Yes, the firm acts on residential and commercial real estate transactions, including purchase and sale agreements, mortgages, title insurance, and transfers of ownership.
Is there a German speaking lawyer at Duensing Law?
Founder Matthias Duensing is fluent in German, and the firm can notarize documents and provide English to German translations for German speaking clients.
Does Duensing Law offer notary and commissioner of oaths services?
Yes. The firm administers oaths, affirmations, and statutory declarations and certifies true copies of documents. Clients need to appear in person with valid identification, since these services can't be done remotely.
How much does it cost to have a will prepared at Duensing Law?
It depends on how complex the estate plan is. The firm says a flat fee is common for straightforward wills, though there's no single price for every client, and it recommends a consultation before quoting a cost.
