Co-owning a home in British Columbia can be a smart way for small families to get into a better home sooner (more space, better school areas, more stability) by sharing the down payment, mortgage, and monthly costs. But co-ownership only works long-term when expectations are clear before you buy.
Below is a practical checklist of what your BC co-ownership agreement should typically cover—so you can walk into lawyer conversations prepared and reduce the risk of future disputes.

Why co-ownership agreements matter more for small families
With kids in the mix, “we’ll figure it out” isn’t a plan—because the home is also your family’s routine, sleep, and stability.
A written agreement helps prevent issues like:
- “I thought you were paying utilities.”
- “We didn’t agree to that renovation.”
- “My family needs to move—what happens now?”
- “Why is it split 50/50 when I paid more upfront?”

Co-ownership agreement checklist (BC)
Use this as a planning checklist. You don’t need every answer today—but you want every topic covered in the final agreement.
1) Ownership structure: joint tenancy vs tenants in common
Clarify upfront:
- Are you taking title as joint tenants or tenants in common?
- If tenants in common: what are the ownership shares (50/50, 60/40, etc.)?
- Hybrid ownership? Combination of both joint tenants and tenants in common
Why it matters: this impacts control, inheritance, and what happens when one party wants out.

2) Down payment + closing costs (document the exact split)
Include:
- Who contributes how much to the down payment
- How you’ll split closing costs (legal fees, inspection, appraisal, adjustments)
- What happens if someone can’t deliver funds on time
Pro tip: If contributions are unequal, your agreement should clearly explain how equity is calculated.
3) Mortgage responsibilities (the “monthly reality”)
Confirm:
- Who is on the mortgage
- Who pays what amount monthly
- Where payments come from (one joint account vs separate transfers)
- What counts as a missed payment and what happens next

4) Ongoing monthly costs: the common friction points
Spell out responsibility for:
- Property taxes
- Home insurance
- Utilities (hydro, gas, water, internet)
- Strata fees (if applicable)
- Routine services (garbage, lawn, snow, pest control—if applicable)
For families: agree on expectations around shared usage and what happens if costs spike.
5) Repairs, maintenance, and an emergency fund
Define:
- What counts as routine maintenance vs major repair
- Who chooses contractors
- Spending limits (example: over $500 requires both approvals)
- Whether you maintain a shared repair fund (recommended) and how much each party contributes monthly
6) Renovations: approval rules + who pays + who benefits
Include:
- What needs joint approval
- Whether improvements change ownership shares (often debated)
- What happens if one party wants a renovation and the other doesn’t
Renovations can increase value and stress—so write the rules down.
7) Use of the home (privacy and boundaries for families)
Agree on:
- Which bedrooms/spaces belong to which family
- Shared space rules (kitchen times, quiet hours, guests, smoking, pets)
- Storage zones, parking spots, outdoor space use
- If there’s a suite/unit: who lives where and whether swaps are allowed
The goal isn’t to be strict—it’s to keep daily life calm.
8) Decision-making: how you’ll make calls without fighting
Document:
- What requires unanimous agreement (selling, refinancing, major repairs/renos)
- What can be decided day-to-day
- Response timelines (example: 72 hours to approve urgent repairs)
9) What happens if someone can’t pay?
Include:
- How long a payment can be late before it’s a default
- Whether the other party can temporarily cover and how repayment works
- What happens if financial strain continues (sale trigger, buyout path, etc.)
10) Exit plan (buyout or sale): the most important section
Define:
- When a co-owner can trigger an exit
- How the home is valued (appraisal process)
- Buyout timelines and process
- What happens if buyout isn’t possible (sale process)
- How you decide listing agent, listing price, and price reductions
- Decide whether or not renting the space can be part of the agreement
A clear exit plan is what makes co-ownership feel safe.
11) Dispute resolution (keep it out of court if possible)
Add a step-by-step process, such as:
- Written notice of the issue
- Meeting within X days
- Mediation
- Arbitration or court (last resort)
This protects relationships and reduces legal costs.
Next step for BC families considering co-ownership
Before you shop seriously, get aligned on:
- your maximum monthly budget,
- your ideal living setup (separate vs shared), and
- your non-negotiables for privacy and kids’ routines.
