Protecting Partnership Interests in Real Estate Held in One Name

THC Lawyers successfully represented Yan Fang in establishing her 50% beneficial interest in a Toronto investment property registered solely in her business partner’s name. In Fang v. Yin, 2024 ONSC 985, the Ontario Superior Court of Justice found that the parties had entered into a real estate partnership and that the registered owner held the property in trust for that partnership. The decision was affirmed on appeal in Fang v. Yin, 2025 ONCA 682.

The case illustrates how written agreements, financial records, and contemporaneous communications can establish a partner’s rights despite sole legal title resting with another person. It also demonstrates the remedies available where a partner denies the arrangement, increases mortgage debt without authorization, and interferes with the other partner’s use of the property.

An investment partnership later denied

Ms. Fang and Mr. Yin agreed to acquire and redevelop a property on Victoria Park Avenue for rental to students. Mr. Yin was an experienced general contractor. Ms. Fang was a recent immigrant and student who knew his sister. Although the property was purchased in Mr. Yin’s name alone, the arrangement contemplated contributions towards acquisition and construction and a sharing of the investment’s returns.

The venture began with several participants. Following another investor’s withdrawal, Ms. Fang and Mr. Yin signed a further joint purchase agreement reflecting Ms. Fang’s 50% interest. The agreement contemplated a C$500,000 mortgage and proportionate contributions to the project’s costs. Ms. Fang provided substantial funds for the acquisition and construction.

The relationship subsequently deteriorated. Mr. Yin took the position that Ms. Fang had merely lent him money and occupied the property as a tenant. He attempted to remove her through landlord and tenant proceedings. Ms. Fang commenced litigation to establish her ownership rights and later discovered that additional mortgages had been registered without her consent.

The evidence established the partnership

The Court assessed the substance of the parties’ arrangement by examining their agreements, communications, contributions, and conduct. The evidence showed that they had intended to carry on a business together for profit, with Ms. Fang holding a 50% interest and the parties sharing costs and revenues.

Mr. Yin argued that the later joint purchase agreement was ineffective because his sister, another named participant, had not signed it. The Court found that this did not defeat Ms. Fang’s claim. Even if the document could not be enforced as a fully executed written agreement, the parties’ conduct established a partnership on the relevant terms. The absence of one signature did not erase the arrangement they had put into practice.

Contemporaneous WeChat messages were particularly important. They recorded discussions about Ms. Fang’s ownership share, contributions, access to accounts, and responsibility for expenses. Bank records supported the transfers and withdrawals used to fund the project. Other documents and communications showed the parties dividing rooms and parking spaces and treating Ms. Fang as a landlord entitled to rental income.

The competing loan and tenancy explanations lacked comparable support. There was no loan agreement setting out repayment terms or interest, and no lease establishing the alleged tenancy. The Court found that Mr. Yin’s position conflicted with the documentary record and his own earlier communications. That record supported Ms. Fang’s account of the investment.

Sole legal title did not defeat beneficial ownership

Having found a partnership, the Court determined that the property was partnership property and that Mr. Yin held it in trust for the partnership. Ms. Fang accordingly held a 50% beneficial interest even though her name did not appear on title.

The distinction matters for investors whose contributions and rights are not reflected in the land register. Registered title identifies the legal owner, but the agreements and circumstances between participants may establish additional beneficial interests. Here, Ms. Fang’s claim succeeded on evidence of the partnership and its terms. A contribution of money alone should not be assumed to establish the same result in every property dispute.

The decision also shows the practical risks of leaving ownership arrangements incompletely documented. Clear terms addressing title, financing, access to records, and exit rights can reduce uncertainty. Where a dispute arises, preserving the original agreements and the communications explaining payments and management decisions can be critical.

Unauthorized mortgages required an accounting

The Court found that the parties had agreed to permit a C$500,000 mortgage. Mr. Yin nevertheless obtained financing beyond that amount without Ms. Fang’s consent, including a later registered mortgage with a face value of C$1,413,750. The Court found breaches of the partnership agreement, fiduciary duty, and trust obligations.

It declared that Mr. Yin was solely responsible for mortgage debt exceeding the agreed C$500,000. That declaration allocated responsibility between the partners; it did not declare the lender’s mortgage invalid. The Court also confirmed that Ms. Fang had paid her share of construction costs and owed no further contribution towards those costs.

A final monetary award required additional evidence. The registered face amount did not establish the current mortgage balance, and the parties’ rental income, carrying costs, and other adjustments had to be reconciled. The Court therefore directed an accounting before an Associate Judge. Establishing ownership and liability resolved central issues, while the reference would determine the financial balance between the partners.

Summary judgment and protection of the property rights

The Court resolved the partnership issues through summary judgment because the documentary evidence permitted a fair determination without a full trial. Unsupported denials did not create a genuine issue requiring trial when measured against the contemporaneous record. For the disputed allegations of assault and harassment, however, the judge heard oral evidence from both parties in a mini-trial before making findings.

Following those findings, the Court granted a permanent injunction preventing interference with Ms. Fang’s use and enjoyment of the property, including access by her family and tenants. The certificate of pending litigation remained in place pending the accounting and any partition and sale motion. The judge identified a buyout or a possible later sale proceeding as potential ways to end the parties’ difficult situation; the decision itself did not order an immediate sale.

The result upheld on appeal

Mr. Yin’s appeal was dismissed in Fang v. Yin, 2025 ONCA 682, leaving the summary judgment and related relief in place. Ran He represented Ms. Fang both on the successful summary judgment motion and as respondent on appeal.

For property investors, the case demonstrates the importance of evidence showing the arrangement the parties actually made and performed. For a partner facing exclusion from an investment, effective relief may require more than a declaration of ownership. In this case, recognition of the beneficial interest, allocation of unauthorized debt, an accounting, and protective orders worked together to address the dispute.
