Buying a Home With Your Partner: Legal & Financial Guide - Uncategorized blog post featured image

Buying a home together is one of the biggest financial commitments you'll make as a couple. Whether you're married, common-law, or in another partnership arrangement, understanding the legal and financial implications protects both of you. Here's everything you need to consider.


Ownership Structures: Critical Decision

How you hold title has significant legal implications:

Joint Tenancy

Features:

  • Equal ownership (50/50 regardless of contribution)
  • Right of survivorship (automatically passes to survivor on death)
  • Cannot will your share to someone else

Best for:

  • Married couples
  • Partners who want automatic succession
  • Equal financial contributors

Tenants in Common

Features:

  • Ownership can be unequal (e.g., 60/40, 70/30)
  • Each share passes through estate (not automatically to partner)
  • Can specify different percentages

Best for:

  • Unequal contributions (one partner contributing more)
  • Blended families with children from previous relationships
  • Investment partners
  • Those who want estate planning flexibility

Financial Qualification: How It Works Together

Combined Income Benefits

Note: Both credit scores matter: lenders consider the lower score for rate purposes, and both scores for approval.

Down Payment Contributions

  • Document who contributes what
  • Keep records of all transfers
  • Important for potential separation
  • Consider a cohabitation agreement

Legal Protections: Know Your Rights

Married Couples

Default protections under family law:

  • Matrimonial home equally shared regardless of title
  • Both spouses have right to live in home
  • Must consent to sale or mortgage
  • Division on separation governed by family law

Consider a marriage contract if:

  • Significant assets from before marriage
  • Inheritance you want to protect
  • Unequal contributions
  • Children from previous relationships

Common-Law Partners

Fewer default protections:

  • Property rights vary by province
  • Title holder may have more rights
  • Contribution matters more legally
  • Common-law status definition varies

Cohabitation agreement strongly recommended:

  • Define what happens if you separate
  • Specify ownership percentages
  • Outline buyout procedures
  • Protect both parties' interests

What Your Agreement Should Cover

Essential Elements

  1. Initial contributions

- Down payment amounts from each
- Source of funds documentation

  1. Ongoing payments

- Who pays mortgage, taxes, insurance
- How maintenance costs are split
- What happens if one can't pay

Protect Your Partnership

Get pre-approved together and we'll guide you through the process.

Get Started
  1. Separation provisions

- How to determine property value
- First right of refusal to buy out
- Timeline for buyout or sale
- How equity is split

  1. Death provisions

- Life insurance requirements
- What happens to the property


Mortgage Responsibility: The Critical Point

Key understanding: Both parties are 100% responsible for the entire mortgage.

This means:

  • Lender can pursue either party for full amount
  • Your credit is affected by partner's payment behavior
  • You can't simply "walk away" from half the debt

Scenarios to Consider

Situation Implications
Partner stops paying You're responsible for full payment
Separation Mortgage continues until refinanced or sold
Partner's credit drops May affect renewal options
Partner's job loss You may need to cover temporarily

What If Things Change?

Separation Options

Option 1: Sell the property

  • Split proceeds per agreement/law
  • Cleanest break
  • Market timing considerations

Option 2: One partner buys out the other

  • Refinance required
  • Buying partner must qualify solo
  • Fair market valuation needed

Option 3: Continue co-ownership temporarily

  • Rare and usually problematic
  • Need very clear terms
  • Defined exit timeline

FAQ

Q: Can one person be on the mortgage but both on title?
A: Yes, but the title holder not on the mortgage is still considered to have an interest and may be required to sign mortgage documents.

Q: What if we contribute unequally to the down payment?
A: Document contributions clearly. Consider tenants in common with proportionate shares, or a cohabitation agreement specifying equity split.

Q: Do we need separate lawyers?
A: For a cohabitation or marriage agreement, yes—each party should have independent legal advice. For the purchase itself, one lawyer can represent both buyers.

Q: What happens if my partner has bad credit?
A: Their credit affects your joint application. Options include: improving credit before buying, one person buying alone, or using a co-signer. We can advise on your specific situation.

Q: Should we buy together if we're not married?
A: Many couples do—just ensure you have a cohabitation agreement. The lack of automatic legal protections makes this documentation even more important.
