"Practising family law is more than a career – it's my calling. I thrive on helping people move forward. I have and will go to the Supreme Court of Canada to achieve a fair and positive result for my client."

Canadian lawyer top 25, Lorne MacLean, QC
Lorne MacLean, KC (King’s Counsel) is the founder of top-rated MacLean Law and one of Canada’s most experienced and highly rated family lawyers dedicated to family law and divorce in British Columbia.

MacLean was been chosen as a top 25 Canadian Lawyer and a BC Leading Business BIV BC 500 winner in the field of complex and high net worth divorce and family law. His firm was just selected by Canadian lawyer Magazine and Lexpert as a 2023 and 2024 Family law Firm of The Year Awardee of Excellence.

He has set the highest record for interim spousal and child support at over $100,000 a month, the highest record for permanent spousal and child support at over $116,000 a month, the highest fines record, set the precedent for international Mareva injunctions, the highest special costs record at $1.5 million, and one of the largest retroactive child support awards in favour of a husband, dismissals of a wife’s spousal support in a high net worth long marriage and he won the leading Canadian case on child custody and the maximum contact principle and so much more.

Lorne has successfully protected clients’ rights since 1983 in the field of high net worth and complex family law disputes, dealing with issues such as spousal and child support, property division, child custody and parenting time and responsibilities disputes, guardianship and access, and marriage-like relationships.

He has earned a reputation as a tough yet thoughtful advocate for his clients. Lorne MacLean’s K.C. designation is an honour that recognizes his exceptional merit and contribution to the BC legal profession.

Lorne has had the rare honour of making two appearances before the Supreme Court of Canada on behalf of the appellants in complex family law cases. Young v. Young remains the leading case on child custody in Canada and Leskun v. Leskun established key principles to be applied to spousal support decisions and when support can be reviewed. MacLean has even more wins on SCC leave applications in cases involving family businesses and express trusts.

He also successfully represented Juanita Nott in Canada’s first frozen embryo custody dispute. Lorne’s infamous high net asset victory includes a record 2019 victory in Devathasan v Devathasan where over $116,000 of combined child and spousal support was awarded along with $20,000 million of property, over $6,000,000 of lump sum support and $1.5 million of special costs. See the Vancouver Sun article here.

Other major wins include a 2019 win in the BC Court of Appeal in Li v. Rao – a high profile multimillion dollar void marriage family case and Lightle v. Kotar where spousal support was nearly tripled and a stock broker’s book of business was deemed family property for the first time.

Acting for a doctor father in a long marriage, MacLean skillfully cross examined his spouse in a substantial spousal support claim and exposed serious credibility issues. The result was a complete dismissal of the spousal support claim and even better, the husband obtained hundreds of thousands form his spouse in retroactive spousal support.

In addition to his courtroom work, Lorne MacLean has published prolifically on numerous topics relating to BC family law and BC divorce. He is a video and blog author and frequent guest on radio and television shows, including Judge Harvey Brownstone’s popular legal education show “Family Matters.

A sought-after resource for both Canadian and US magazines and newspapers, he has also served as a guest lecturer at the UBC Law School and has lectured and been interviewed about his multiple innovations in the efficient delivery of client-based services that increase clients’ participation in – and reduce clients’ costs of their cases. He also provides considerable free family law information to the general public.

Lorne MacLean lives life to the fullest, loves running and weight lifting, jazz music, strategy games, and travelling with his family. He especially loves to find the “hidden gems” in the cities he visits on his world travels. Along with keeping his mind sharp, Lorne is avid about keeping physically healthy with bootcamps and cross-fit, half marathons and biking.

Xu v Hu, 2021 BCCA 2 2020 Lorne MacLean KC and Susanna Chen won an important multimillion-dollar family law appeal where the son in law of their client sought $50 million at trial. The claim was restricted at trial to 25% of the equity in a multimillion-dollar Shaughnessy home. On Appeal by MacLean Law the BC Court of Appeal held the 3 certainties required for an “express trust” were not met. MacLean Law argued he should receive zero and won a total victory.

Devathasan v. Devathasan, 2020 BCCA 209 Canadian record property division, support and special costs award upheld on appeal. Our client applied for an order that the underlying appeal be dismissed as abandoned for the failure of the appellant to comply with the conditions of an order extending time for the filing and serving of the notice of appeal, and filing of the appeal record and transcripts.

Held: Application granted, appeal dismissed as abandoned. A single justice in Chambers has jurisdiction to dismiss an appeal as abandoned due to failure to meet the conditions of an extension of time order, pursuant to s. 10(2)(e) of the Court of Appeal Act. The appellant has a long history of noncompliance with court orders. His argument that he is unable to meet the conditions of the order for extension of time were previously rejected and the appellant has simply made choices not to comply with the order. The appellant has no reasonable explanation for his noncompliance with the order that would change the balance of the interests of justice. In the end result the multimillion dollar property awards, record setting $116,000 a month spousal and child support award, the multimillion dollar lump sum award and the record $1.5 million special costs award were all upheld.

Devathasan v. Devathasan, 2020 BCCA 115 The appellant applied under s. 9 of the Court of Appeal Act to vary the conditions established by a single justice in granting his application for an extension of time to commence his appeal. The conditions require the appellant to pay a minor portion of the sums owing to the respondent under the order appealed.

Held: Application successfully dismissed. The appellant did not meet the criteria for a variation established in Haldorson v. Coquitlam (City), 2000 BCCA 672.

Devathasan v. Devathasan, 2019 BCCA 436 The appellant applies for an extension of time to appeal an order concerning the division of assets and spousal and child support. He has not complied with the order.

Held: Application granted, subject to conditions that would bring the appellant in partial compliance with the order under appeal. One of the highest awards for conditions in BC and cited as a top 5 BC Appeal decision.

Li v Rao, 2019 BCCA 265 Lorne MacLean, KC won at trial and in the BC Court of Appeal on a multimillion dollar international divorce case. Appeal from dismissal of application to strike a claim for division of property and spousal support under Family Law Act. Appellant argued the judge erred in concluding that a party to a marriage that is declared void ab initio is a “spouse” within the meaning of the Family Law Act.

Held: Appeal dismissed. The judge did not err in interpreting the definition of “spouse”. Parties to a marriage that is declared void ab initio remain entitled to division of family property and spousal support under the Family Law Act.

Devathasan v. Devathasan, 2019 BCSC 661 Record breaking international divorce and family law Trial judgment with client obtaining 20 million plus of family property, $100,000 a month spousal support, nearly $17,000 child support for 1 child, retroactive and lump sum support of roughly $6 million and 100% indemnity for special costs in the amount of 1.5 million.

Solis v. Tibbo Lenoski, 2015 BCCA 531 The appellant father applies for a stay of proceedings on a judgment of this Court pending his application for leave to appeal to the Supreme Court of Canada. The appeal concerns the interpretation of Article 13(b) of the Hague Convention. The father had removed his twin boys from their habitual residence with their mother in Mexico. One of the boys, D, has autism and is undergoing intensive autism treatment in Vancouver. The father claimed that the unavailability of appropriate autism therapy in Mexico engaged the grave risk of harm exception in Article 13(b). The chambers judge ordered the boys to be returned to Mexico and this Court upheld that decision.

Held: Application allowed. With respect to the merits of the appeal, there is a sufficient likelihood that the Supreme Court of Canada might grant leave to appeal. As for irreparable harm, the findings of fact of the chambers judge suggest that D may suffer serious harm if he is returned to Mexico and any such harm would likely be irreparable given the time-sensitive nature of his treatment. Finally, the balance of inconvenience favours granting a stay.

Dominak v. Lockhart, 2014 BCCA 432 Successfully acted for a senior family lawyer who was alleged to have reached a settlement by way of letters between counsel. Appeal from an order staying family law proceedings on the basis that an enforceable settlement agreement had been reached. The appellant argued that the parties had not agreed on the issue of the division of family assets and there was no binding agreement. The chambers judge excluded the first two pages of the letter proposing the settlement as “campaign talk”, and found an “objectively reasonable” settlement in the terms set out on the third page only.

Held: appeal allowed. There was no binding agreement. The parties had not agreed on the important issue of the division of assets. The chambers judge failed to consider all of the evidence of all of the material facts and to determine the entire scope of the settlement.

Moradkhan v. Mofidi, 2013 BCCA 132 Lorne MacLean, KC successfully obtained a new trial after a previously unrepresented husband had failed to have lucrative real estate holdings to be valued by a certified business expert such that the value used initially was only half of the true value resulted in substantially increased monies for the husband.
