Am I Ready to File for Divorce?

Grounds for Divorce in Canada and the US

Canada has a single divorce law nationwide — the Divorce Act — and it recognizes one ground for divorce: breakdown of the marriage. Breakdown is proven three ways: living separate and apart for at least one year, adultery, or physical or mental cruelty. The overwhelming majority of Canadian divorces use the one-year separation route because it requires no proof of wrongdoing; the adultery and cruelty routes avoid the one-year wait but must be proven, which is slower and more contentious in practice. You can even be 'separated' while living under the same roof if you are genuinely living separate lives.

The United States has no federal divorce law — each state sets its own rules. Every state now offers no-fault divorce (often described as 'irreconcilable differences' or 'irretrievable breakdown'), and many states also retain fault grounds such as adultery, cruelty, or abandonment that can influence spousal support or property division. Some no-fault states, such as North Carolina, require a separation period of a year; others, like Nevada, impose no waiting separation at all. Because the ground you choose affects both timing and cost, it should be one of the first things you confirm.

Residency and Separation-Period Requirements

Before a court will hear your divorce, you must satisfy a residency requirement. In Canada, either spouse must have been ordinarily resident in the province or territory where you file for at least one full year immediately before the application. In the US, residency rules vary widely: most states require between three months and one year of residency in the state, and many also require a shorter period (often 90 days) in the specific county. Filing before you meet the requirement typically results in dismissal, so confirming the exact date you become eligible is essential.

Separately from residency, many jurisdictions require a period of separation before a no-fault divorce is granted. Canada's one-year separation is the classic example; US separation periods range from none to a year depending on the state. The separation clock generally starts the day the couple begins living separate and apart — which can include continuing to share a home while leading separate lives. Because this date anchors both eligibility and related property and support deadlines, writing it down accurately is one of the most valuable early steps you can take.

Practical, Financial, and Emotional Readiness

Legal eligibility is only half of readiness. Practically, you should know your household income and monthly expenses, have access to your own bank account and credit, gather three years of tax returns, and understand roughly what child support, spousal support, and property division could look like in your case. Full financial disclosure is mandatory in every Canadian province and US state, so getting organized early both protects you and speeds the process. If you suspect a spouse is hiding assets, preserving records before filing is far easier than reconstructing them later.

Emotional readiness carries no legal weight, but it shapes decision quality. Agreements signed in acute crisis are the ones most often revisited, so a support network, counselling, and a clear head improve the durability of what you negotiate. Finally, deciding early whether your divorce will be uncontested — where you and your spouse agree on parenting, support, and property — is what makes the fastest, cheapest path possible: an uncontested or joint divorce can cost a few hundred to a couple thousand dollars, while a contested divorce can run into the tens of thousands.
