Buying property with a partner, whether a spouse, friend, family member, or business associate, can be an exciting step. For many Albertans, entering into a joint mortgage is the only practical way to purchase real estate in today’s market. However, sharing ownership of a property also entails legal and financial obligations that should not be overlooked.

Before committing to a joint mortgage, it’s essential to understand the legal framework, risks, and protections available under Alberta law. This blog outlines the key considerations for anyone considering co-owning property in the province.

What Is a Joint Mortgage?

A joint mortgage is a home loan taken out by two or more people who share the responsibility for repaying it. All parties listed on the mortgage are equally liable for the debt, regardless of how the property’s ownership is divided.

In Alberta, joint mortgages are commonly used by:

  • Married or common-law couples buying a family home
  • Parents helping adult children get into the housing market
  • Siblings pooling funds to invest in real estate
  • Friends or business partners purchasing property together

While the financial appeal is strong, especially in a challenging real estate market, the legal implications of joint ownership can be complex.

Joint Tenancy vs. Tenancy in Common

When two or more people buy property together in Alberta, they must decide how they will hold legal title to the property. There are two primary options:

1. Joint Tenancy

Under joint tenancy, all owners have an equal interest in the property, and the right of survivorship applies. This means that if one owner dies, their share automatically passes to the surviving owner(s), regardless of what their will says.

Joint tenancy is most common among married or long-term partners because it aligns with shared ownership and estate planning goals.

2. Tenancy in Common

With tenancy in common, each owner can hold a different percentage of ownership (e.g., 60/40 or 70/30), and there is no right of survivorship. If one owner dies, their share passes according to their will or intestacy rules.

This structure is typically used by co-investors or non-spousal partners who want to retain independent control over their share of the property.

Mortgage Liability: Equal Responsibility, No Matter the Share

A critical legal point for joint mortgage holders in Alberta is that liability for the mortgage is joint and several. This means that each person on the mortgage is responsible for the full amount of the loan, not just their share of it.

For example, if one party defaults on payments, the lender can pursue the other for the entire balance. This can lead to significant legal and financial consequences if one co-owner becomes insolvent or refuses to contribute.

Therefore, it’s vital to have a clear agreement in place that outlines who is responsible for making payments, how costs are shared, and what happens if one person wants out.

Drafting a Co-Ownership Agreement

One of the best ways to protect your interests when entering a joint mortgage is to create a co-ownership agreement. This legal document outlines the rights, obligations, and expectations of each party.

A well-drafted agreement should cover:

  • Ownership shares (e.g., 50/50 or otherwise)
  • Contribution to down payment, mortgage, taxes, and maintenance
  • What happens if one party wants to sell or exit
  • Dispute resolution processes
  • Buyout terms in case of breakdown or default

While not required by law, a co-ownership agreement is strongly recommended, especially in arrangements involving friends, siblings, or business associates. It helps prevent misunderstandings and provides a legal framework for resolving conflicts.

What Happens If the Relationship Breaks Down?

One of the most common issues with joint mortgages arises when the relationship between co-owners deteriorates. Whether due to divorce, disagreement, or financial stress, a communication breakdown can lead to disputes over the property.

Some potential scenarios include:

  • One party wants to sell the home, while the other does not
  • One party stops contributing to mortgage payments or expenses
  • One party moves out and expects to be bought out
  • One party wants to refinance or change the mortgage terms

If there is no co-ownership agreement in place, the matter may need to be resolved through negotiation, mediation, or, ultimately, litigation in the courts.

Selling the Property or Buying Out a Co-Owner

If one party wishes to leave the arrangement, several options are available:

1. Sell the Property

This is the most straightforward solution. The property is sold, and the proceeds are divided according to ownership shares.

2. Buyout by One Party

If one party wants to retain the property, they may offer to buy out the other party’s interest. This usually involves refinancing the mortgage to remove the departing party from the loan and land title.

The buyout value is typically negotiated based on market value and outstanding mortgage balance, and a lawyer should oversee the transaction to ensure fair terms.

Legal Implications of Missed Payments or Foreclosure

If mortgage payments are missed, all parties suffer the consequences—even if only one person is at fault. A missed payment can impact all co-borrowers’ credit scores and potentially lead to foreclosure proceedings.

In Alberta, foreclosure is a legal process that allows a lender to recover the balance of a loan by forcing the sale of the property. The process is court-supervised and can take anywhere from months to years, depending on the circumstances.

To prevent foreclosure, co-owners should closely monitor payments and ensure timely contributions are made. Financial difficulties should be addressed promptly, and at the first sign of trouble, consulting a lawyer is crucial.

Tax Considerations for Joint Property Owners

Owning property with another person may also have tax implications, especially if the property is not your principal residence.

Some issues to consider:

  • Capital gains tax may apply if the property is sold, and it was not your primary residence
  • Rental income from jointly owned property must be reported and split according to ownership shares
  • Land transfer tax exemptions may not apply in all joint ownership situations

Consulting with a tax advisor or lawyer familiar with Alberta real estate law is wise when planning a co-ownership arrangement.

Getting Legal Advice Before You Sign

A real estate lawyer plays an essential role in reviewing mortgage documents, advising on title registration options, drafting co-ownership agreements, and resolving disputes or breakdowns.

Even if you trust your co-owner completely, legal advice can help prevent future misunderstandings and provide clarity on what happens in unexpected circumstances such as death, divorce, or financial hardship.

Plan Ahead to Protect Your Interests

Joint mortgages offer a practical path to homeownership and real estate investment, but they also create shared legal and financial responsibilities. Whether you’re buying with a spouse, family member, or friend, taking the time to understand your rights and obligations can save considerable stress and cost down the road.

Before you sign a joint mortgage in Alberta, speak with a real estate lawyer to review your options, discuss the best form of ownership, and ensure that proper legal agreements are in place. With the right legal foundation, co-owning property can be a successful and rewarding experience.
