Chip Wilson's missing prenup is now a governance problem

Few documents in a founder's life cost as little to sign and as much to skip. Chip Wilson, 71, founded Lululemon in 1998 and is now divorcing Shannon “Summer” Wilson after more than two decades of marriage; the couple reportedly never signed a prenuptial agreement, which leaves British Columbia's default property law, not a drafting table, to divide a combined fortune estimated at roughly $6.1 billion and the voting weight attached to it.

The equity is legible even though the proceedings are not. Chip holds about 8.6% of Lululemon, worth roughly $1 billion, while Summer, among the company's earliest employees and its founding lead designer, independently holds about 1%, worth roughly $100 million; the couple also owns a Point Grey waterfront home in Vancouver assessed at around $73 million and holds further assets through their family company, House of Wilson. The divorce, filed in the Supreme Court of British Columbia in April 2026, is not public, so its effect on that balance sheet can only be inferred.

British Columbia's Family Law Act supplies the default a prenup would have replaced: Section 81 gives each spouse an undivided half interest in family property, defined as the gain in value of assets during the marriage, regardless of use or contribution, while property brought into the marriage stays separate. The Wilsons married in 2002, four years after Lululemon was founded and two years after its first Vancouver store opened, which puts most of the company's assets in the shareable column.

For Lululemon, the division question is governance before it is law. The coverage in Inc. sketches two paths: transfer shares to Summer, which fragments ownership and voting control, or arrange a buyout that leaves Chip the shares and pays her in cash or other assets. For a company the coverage already calls turbulent, the first path changes who votes; the second leaves the cap table intact and puts the strain on a single founder's liquidity.

Family offices and RIAs inclined to read this as someone else's business might note what a prenuptial agreement would have priced: the one asset a household cannot diversify away, control of the operating company, signed while both spouses still wanted the same outcome. The Wilsons married after Chip founded the business and before it compounded, the exact window in which a marital agreement does the most work and gets signed the least. The choice now runs between fragmenting the cap table and draining the founder's balance sheet, and neither is the one a family office would pick on an unpressured afternoon.
