Fault-Based Divorce and Asset Allocation

Status: Early discussion draft
Category: Justice & Safety → Family Law

What is the proposal?

Canada would end no-fault divorce as the default model and replace it with a system that assigns each spouse a percentage of responsibility for the breakdown of the marriage.

The percentages would work in a way similar to comparative negligence in a civil lawsuit. After hearing the evidence, a jury would assign responsibility between the spouses, with the two percentages adding up to 100 per cent.

That allocation of fault would then affect how the spouses' net family assets are divided.

How the process would work

A contested divorce would proceed through a formal jury process similar in structure to a trial. It could include:

1. jury selection;
2. opening statements;
3. preliminary legal and evidentiary issues;
4. testimony from both spouses and other witnesses;
5. documentary and expert evidence where relevant;
6. cross-examination;
7. closing arguments;
8. instructions from the judge; and
9. a jury verdict assigning a percentage of fault to each spouse.

The judge would control the law, rule on admissibility, protect privileged and irrelevant information, and translate the jury's fault findings into the final financial order.

Standard of proof

Because the proceeding would determine civil and financial consequences rather than criminal guilt, the proposed standard would be the balance of probabilities.

This means the jury would decide whether an allegation is more likely than not to be true. The proposal could later consider whether particularly serious allegations should require stronger corroborating evidence, but it would not use the criminal standard of proof beyond a reasonable doubt.

What could count as marital fault?

The exact categories remain to be developed, but possible forms of fault could include:

• adultery;
• physical, sexual, or serious emotional abuse;
• coercive or controlling conduct;
• abandonment without reasonable cause;
• deliberate financial deception;
• intentional or reckless depletion of family property;
• serious and repeated breach of agreed marital responsibilities;
• conduct that made continued cohabitation unsafe or intolerable.

Ordinary incompatibility, loss of affection, personality conflict, or a good-faith decision to leave an unhealthy marriage would not necessarily amount to serious fault.

How fault would affect property division

The present equalization calculation would provide a starting point. The jury's percentages would then adjust the division of net family assets.

For example, if one spouse were found 75 per cent responsible and the other 25 per cent responsible, the spouse carrying the greater share of fault could receive a smaller share of the divisible family property.

The exact formula is not yet settled. Future discussion must determine:

• whether fault should adjust only the equalization payment or all family assets;
• how large the maximum financial penalty should be;
• whether minor fault should have any financial effect;
• whether severe abuse or deliberate asset depletion should justify a much larger departure;
• whether prenuptial and marriage contracts could modify the system.

Issues involving children

Fault between spouses would not automatically determine parenting time or decision-making responsibility.

Questions involving children would remain governed by the child's safety and best interests. Evidence of abuse, violence, coercive control, neglect, or other harmful conduct could still be relevant, but a spouse would not gain parenting rights merely because the other spouse was assigned more responsibility for the marital breakdown.

Current Canadian context

Canada currently permits divorce on the basis of marriage breakdown, including one year of separation, adultery, or physical or mental cruelty. In practice, the one-year separation ground allows divorce without proving wrongdoing. Ontario generally equalizes the increase in spouses' net family property, subject to limited exceptions for unconscionable results and certain forms of financial misconduct.

This proposal would replace that general no-fault approach with a system in which marital conduct is formally tried and can materially change the financial outcome.

Arguments in favour

Supporters may argue that the proposal would:

• restore consequences for serious marital misconduct;
• prevent a spouse who caused the breakdown from receiving the same financial result as the other spouse;
• allow community judgment through a jury rather than leaving the decision entirely to one judge;
• create a detailed public process for testing allegations;
• discourage abuse, adultery, abandonment, and deliberate financial wrongdoing.

Arguments against

Potential objections include:

• divorce proceedings could become longer, more expensive, and more hostile;
• spouses could exaggerate or manufacture allegations for financial advantage;
• intimate and humiliating evidence could be exposed in open court;
• jury decisions could be inconsistent or influenced by cultural, religious, or gender bias;
• victims of abuse could face further trauma through cross-examination;
• settlement and cooperation could become more difficult;
• unequal access to lawyers and experts could distort the result;
• attaching money to blame could intensify conflict around children.

Questions still to be discussed

• Which specific acts should count as fault?
• Should a spouse be able to obtain an uncontested divorce without a jury where both parties agree on fault and property?
• Should every contested divorce require a jury, or only cases where fault would affect property?
• Should the jury consist of six, eight, or twelve people?
• Must the jury reach unanimity, or would a strong majority be enough?
• How should courts protect private medical, sexual, and family information?
• What limits should exist on the financial consequences of fault?
• Should family violence cases use additional procedural protections?
