About Ballantyne Family Law

Ballantyne Family Law does family law and nothing else, helping people with everything from a straightforward divorce to a separation tangled up in hard parenting or money questions. The team's aim is representation that's compassionate and thoughtful while keeping costs in check.

The team is trained in collaborative law. Depending on what a file needs and how complicated it is, the firm may suggest the collaborative process, negotiation, mediation or arbitration, with the goal of helping clients make sound choices that protect their financial security and their family relationships. When a matter is urgent, or nothing else has worked, the lawyers go to court for their clients at the Ontario Court of Justice, the Superior Court or the Court of Appeal.

Karen Ballantyne has practised family law since 2003. Nadine Waldman, called to the Bar in 2008, can work with clients in French as well as English, and Lily Chapnik, called in 2022, trained as a social worker as well as a lawyer. Law clerk Bonnie Frieday, whose background includes court reporting, legal research and legal writing, helps clients prepare their financial statements and put together simple divorce applications, and consultations are booked through Bonnie.

When parenting or financial issues call for it, the firm can retain outside professionals on a client's behalf. Its regular collaborators range from mediators, therapists and child psychologists to business valuators and tax specialists, along with lawyers in related fields like estates, criminal and real estate law. The office is in midtown Toronto, at 10 Alcorn Avenue, Suite 201.

Practice areas

Cohabitation agreements and marriage contracts

Couples planning to live together or marry can have the firm negotiate a cohabitation agreement or marriage contract that's fair to both partners. The lawyers work through what each partner has to do so the contract can be enforced if the relationship later ends.

Parenting and support

Parenting issues are a focus of Karen Ballantyne's practice. The firm helps parents negotiate a schedule built around a child's age, development and particular needs, makes sure children's financial needs are covered, and works out whether a client is entitled to spousal support.

Property claims for married and common-law spouses

Married spouses' property rights are set by provincial legislation, while common-law spouses can't claim equalization but may have trust claims or claims based on a joint family venture. The firm's lawyers guide clients through both sets of rules.

Litigation and arbitration

When a dispute won't settle, the firm represents clients in litigation or arbitration, and it has handled separation and divorce cases across southern Ontario. Karen Ballantyne and Nadine Waldman have each appeared at every level of the Ontario courts, the Court of Appeal included.

The neighbourhood

The firm works from Suite 201 at 10 Alcorn Avenue, a brick and stucco building that was completely restored in 1991. Homes stood on the site between 1902 and 1925, and from 1925 to 1950 the address belonged to two hardware companies, Walkers and Sons Ltd. Wholesale Hardware and Whites Hardware. Inside, the lobby pairs terrazzo floors with mahogany detailing, and both it and many of the suites look out on a sunny interior courtyard.

The building sits just west of Yonge Street in midtown Toronto, a two-minute walk from Summerhill subway station, with a bus stop about a minute away.
