Key takeaways
  • CPP credit splitting is available to separated or divorced spouses and former common-law partners who meet the 12-month tests.
  • Only credits earned during the time you lived together are divided, and the split is permanent.
  • Time limits can apply for common-law unions or if a former partner dies.
  • CPP credits are not part of equalization; they are dealt with by credit splitting instead.

If you have separated, you may have heard that you can share Canada Pension Plan credits with your former partner. This can matter most where one person earned much more than the other, or stayed home for years.

This article explains in plain language who can split CPP credits, what is and is not divided, how to apply, and how it differs from dividing a workplace pension. A lawyer can confirm how the rules apply to your agreement or order.

What CPP credit splitting is

The Canada Pension Plan records pensionable earnings, often called credits. Under the Act, those credits (unadjusted pensionable earnings) can be divided on application after a divorce or nullity, or after spouses or common-law partners have lived separate and apart for one year or more. The persons must have cohabited for a continuous period of at least one year.

Either spouse or former common-law partner can request the split. The aim is to share the pension credits built up while you lived together, so each person's own record reflects that shared period.

Who is eligible

For separated spouses who are still legally married, the split is available for separations on or after January 1, 1987, where you lived together at least 12 consecutive months and lived apart at least 12 consecutive months. Common-law unions that ended on or after January 1, 1987 follow the same 12-month tests, with some exceptions.

A new partner or a remarriage does not prevent you from applying.

What is not split

Not every period is divided. Credits are not split for periods before either person turned 18, after either turned 70, while either received a CPP or QPP retirement pension or was considered disabled, or for a year when both spouses' combined pensionable earnings were not more than twice the Year's Basic Exemption.

Only credits earned during the cohabitation period are divided, and the split is permanent.

One consequence to be aware of: a separated legal spouse who received an approved credit split in January 2025 or later, with the same deceased contributor, is not eligible for a survivor's pension, unless they reunited and lived together 12 months or more immediately before the death.

How to apply and the time limits

You can apply through My Service Canada Account by completing the online CPP Credit Split form and then mailing copies of the required documents, or you can apply on paper with form ISP1901. For a separation, one spouse's signature is required.

SituationTime limit
Divorce on or after 1987, or separation of spousesNo time limit, unless the spouse dies, then 36 months from the death
Common-law unionWithin 48 months of starting to live apart, unless the former partner is alive and agrees in writing to waive the limit

The Act similarly sets a four-year window for separated common-law partners, unless both agree in writing to a later application, and a three-year window after a separated spouse's death if they had lived apart for a year. Because the rules differ, check your own dates before assuming you have time.

Agreements and orders do not always control

Many people assume that a separation agreement or court order can waive CPP splitting. Generally, agreements and court orders are not binding on the Minister for a credit split. The exception is an agreement that expressly refers to the Act, shows an intention that there be no division and meets the listed conditions.

If your agreement says something about CPP, have a lawyer confirm whether it would actually stop a split.

How it differs from dividing a workplace pension

CPP is not divided through the property equalization process. CPP unadjusted pensionable earnings are excluded from net family property, whereas workplace pensions count as property valued in the equalization. Equalization applies to married spouses, not to common-law partners.

What to do next

Start by confirming your dates and gathering what you need, then decide whether to apply now or speak to a lawyer first, especially if you are common-law and the 48-month limit may be near.

Frequently asked questions

Is there a deadline to split CPP credits?

After a divorce or a separation of spouses, there is generally no time limit, unless your spouse dies, in which case it is 36 months from the death. For common-law unions, apply within 48 months of starting to live apart unless your former partner is alive and agrees in writing to waive the limit.

Can my spouse refuse to sign?

Either spouse or former common-law partner can request a split, and for a separation one spouse's signature is required. Details of how this works in your case are worth confirming with a lawyer.

Is the split permanent?

Yes. Only the credits earned during the cohabitation period are divided, and the split is permanent. A new partner does not prevent you from applying. How a later change in your situation affects things depends on your facts, so it is worth confirming with a lawyer.

Do I still divide my workplace pension if I split CPP?

They are separate. CPP credits are excluded from net family property, while workplace pensions count as property in the equalization. You may need to deal with both.
