How to force the sale of a jointly owned house (Partition and Sale) in Hamilton

💡

Under Ontario’s Partition Act, if a co-owner refuses to sell a jointly owned property in Hamilton, you can apply to the Superior Court of Justice for an order forcing the sale. The initial court filing fee for this application is approximately $356 CAD.

Co-owning real estate in Hamilton is a common way to enter the housing market, whether with a sibling, a business partner, or an unmarried romantic partner. However, when relationships break down or financial goals change, one owner might desperately want to cash out while the other outright refuses to list the property. This creates a deeply stressful legal stalemate.

You are not trapped in this co-ownership forever. 🔓 In Ontario, the law generally recognizes that no one should be forced to remain in a joint property investment against their will. Through a legal mechanism known as a “Partition and Sale,” you can ask a judge to intervene and order the property to be sold on the open market, with the profits divided appropriately.

While the right to force a sale is very strong, the legal procedure requires strict adherence to the Ontario Rules of Civil Procedure. We will guide you through exactly how this litigation works in the local Hamilton jurisdiction and what steps your legal team will take to get your investment unlocked.

Step-by-Step Process in Hamilton

Litigation should always be a last resort, but if your co-owner is completely unreasonable, you must take formal action. 🏫 The process runs through the civil courts and requires compiling undeniable evidence of your ownership and your attempts to resolve the matter privately.

Step 1: Attempting a Negotiated Buyout

Before filing a lawsuit, your law firm will typically send a formal demand letter to the co-owner. This letter will lay out their options: either buy out your share at fair market value, allow you to buy their share, or agree to list the house voluntarily with a Hamilton real estate agent. Often, the mere threat of a costly court battle is enough to bring a stubborn co-owner to the negotiating table.

You will need a professional appraisal to establish the current fair market value of the home. 📈 Do not rely on automated online estimates; courts and opposing lawyers require a certified report from an accredited local appraiser.

Step 2: Filing the Notice of Application

If negotiations fail, your real estate litigation lawyer will draft a Notice of Application under the Partition Act. In Hamilton, this legal document is filed at the Superior Court of Justice, located at the John Sopinka Courthouse on Main Street East. The application formally requests that a judge order the sale of the property.

You must also file an affidavit. 📄 This is a sworn statement detailing the history of the property purchase, who has been paying the mortgage and property taxes, and why the relationship between the owners has broken down.

Step 3: The Court Hearing

The co-owner (the respondent) will have a chance to file their own responding affidavit, attempting to explain why the sale should not happen. However, under Ontario law, there is a “prima facie” right to a partition and sale. This means the judge will almost always grant your request unless the other owner can prove “malice, oppression, or vexatious intent” on your part.

Simply not wanting to move, or claiming it is a bad time in the Hamilton real estate market, is generally not a valid legal excuse to block the sale. 👨‍⚖️

Step 4: The Order for Sale and Accounting

Once the judge grants the order, they will set specific terms. They will usually appoint a neutral real estate broker to list the property and sign the closing documents if the other owner continues to be uncooperative. The house is then sold, and the mortgage is paid off.

The final step is the “accounting.” 💰 If you paid for all the major roof repairs and property taxes for the last five years while the other owner paid nothing, your lawyer will argue that you should receive a larger share of the final net proceeds to reimburse you for those carrying costs.

How Much Does it Cost in Hamilton?

Forcing a sale through the Superior Court is a highly procedural form of litigation that requires experienced legal counsel. Be prepared to fund the lawsuit upfront, though sometimes you can request that your legal costs be paid out of the final sale proceeds.

Expense CategoryEstimated Cost (CAD)
Superior Court Filing Fee (Application)$356
Professional Property Appraisal$400 – $800
Lawyer’s Fees (Uncontested/Settled)$3,000 – $6,000
Lawyer’s Fees (Fully Contested Hearing)$7,000 – $15,000+

Remember that you will also have to pay standard closing costs once the house finally sells, such as real estate agent commissions and the discharging of the mortgage. 💳

How Long Does the Process Take?

Civil litigation timelines in Ontario rely heavily on the availability of court dates. If the other owner realizes they will lose and agrees to a settlement after receiving the Notice of Application, the matter can be resolved in 2 to 3 months.

If they stubbornly fight the application all the way to a formal hearing at the Hamilton courthouse, securing a hearing date and getting the final judgement typically takes anywhere from 6 to 12 months. ⏳️

Frequently Asked Questions (FAQ)

Can this be used for a matrimonial home during a divorce?

No. If you are legally married, the sale of the matrimonial home falls under the Family Law Act, not the Partition Act. You must resolve the sale through family court proceedings in Hamilton.

What if the other owner stops paying the mortgage during the lawsuit?

You must ensure the mortgage is paid to avoid foreclosure by the bank. Keep meticulous records of any extra payments you make. During the final accounting phase, your lawyer will ask the judge to deduct those missed payments from the other owner’s share of the profits.

Do I have the right to buy their half before it hits the market?

Yes, courts generally prefer this. A judge will often grant a right of first refusal, allowing one co-owner to purchase the other’s interest at the appraised fair market value before the property is listed publicly.

Can they block the sale by claiming they have nowhere else to live?

Generally, no. Personal inconvenience or financial hardship of one owner does not override the other owner’s absolute right to liquidate their investment under Ontario law.

What if my co-owner has completely disappeared?

You can still apply for a Partition and Sale. Your law firm will file a motion for substitute service or to dispense with service entirely, proving to the court that you have made every reasonable effort to locate them.
