Stokes v Heck, 2023 ABCA 392023

Counsel of Record: Marcus M. Sixta & Camille Boyer 

Case Summary: After years of conflict and legal battles, the wife in this case, represented by Marcus Sixta and Camille Boyer, secured a significant win in court. She was granted exclusive rights to list and access a property, which she successfully sold for more than what her husband had estimated. The court rejected her husband's attempt to stay or set aside the order, noting that he wouldn't suffer irreparable harm. The decision eased the wife's considerable debt and allowed her to receive overdue child support from the sale proceeds, ultimately favouring her in both property and financial matters.

Stokes v Heck, 2023 ABKB 582023

Counsel of Record: Marcus M. Sixta & Camille Boyer 

Case Summary: Despite numerous attempts by the husband to challenge and delay the sale of a jointly-owned recreational property, with which the wife had been solely responsible for, Marcus Sixta and Camille Boyer were able to achieve success and have him found in contempt of court for repeatedly disregarding court orders. Financial penalties were deemed insufficient, leading the court to take the exceptional step of ordering the husband's imprisonment until he complied.

J.D. v S.G, 2021 BCSC 5102021

Counsel of Record: Marcus M. Sixta

Case Summary: Marcus Sixta effectively advocated for the claimant wife who had been solely responsible for the mortgage on the family home, despite no longer living in it. Recognizing the significant emotional and financial toll on her and their children, the court authorized the sale of the home without requiring her husband's consent. The husband's claims of financial hardship were scrutinized and dismissed, further justifying the court's decision to alleviate the wife's burden of carrying the mortgage alone.
