What Happens to CPP After Divorce? Credit Splitting Explained

CPP is not divided after divorce in the same way as money sitting in a bank or investment account. Instead, Canada Pension Plan (CPP) credit splitting can change the pensionable earnings recorded for the years you and your former spouse or common-law partner lived together. That revised record can then affect each person’s current or future CPP benefits.

CPP credit splitting divides eligible CPP pension credits earned by both partners during the period they lived together. For each eligible year, their pensionable earnings are generally added together and divided equally between them. The resulting change is permanent and can increase one person’s CPP benefits while reducing the other’s.

What CPP Credit Splitting Actually Divides

Despite the name, a CPP credit split does not divide CPP payments already sitting in someone’s account. It changes the pensionable earnings recorded under CPP for eligible years of the relationship. Those earnings are important because they are used when CPP benefits are calculated.

Consider a simplified example. If one spouse had $60,000 of pensionable earnings in an eligible year and the other had $20,000, their combined pensionable earnings would be $80,000. A credit split would generally assign $40,000 to each person for that year, subject to the CPP rules and annual pensionable earnings limits. The higher earner loses credits while the lower earner gains them.

The same process is applied to eligible years during the period the couple lived together. A split can occur even when only one person contributed to CPP. However, not every calendar year spent together necessarily qualifies, so dividing one spouse’s entire lifetime CPP record in half would give the wrong picture.

Which Years Can Be Included in a CPP Credit Split?

The credit-splitting period is based on the years you lived together, but CPP excludes certain periods. Credits cannot be divided for a year when the couple’s combined pensionable earnings were no more than twice the Year’s Basic Exemption. Periods before either person reached 18 are also excluded.

CPP also excludes periods after either spouse or former partner reached 70. A period when one person was receiving a CPP or Quebec Pension Plan (QPP) retirement pension cannot be split, nor can a period when one person was considered disabled for CPP or QPP disability-benefit purposes.

Those exclusions are one reason the final split can look different from simply counting the number of years between the wedding and divorce. Once completed, a credit split appears on your CPP Statement of Contributions with the code “CS” beside affected pensionable earnings.

Who Can Get a CPP Credit Split After Divorce?

The rules depend on the type of relationship and when it ended. For a divorce or legal annulment on or after January 1, 1987, the former spouses generally qualify if they lived together for at least 12 consecutive months. Either former spouse can provide the information needed for the split, and there is no application deadline.

Older divorces have different rules. A divorce or annulment that occurred between January 1, 1978 and December 31, 1986 generally required at least 36 consecutive months of living together and a written application within 36 months. A late split can still be possible when the former spouse is alive and agrees in writing to waive that deadline. Divorces that occurred before January 1, 1978 do not qualify because CPP credit splitting did not yet exist.

A divorce agreement also does not automatically prevent CPP credits from being divided. Certain written agreements can prevent a split, including qualifying agreements made before June 4, 1986 and agreements covered by applicable legislation in Quebec, Saskatchewan, British Columbia and Alberta. Because the exception depends on the agreement and provincial law, the existence of a clause about CPP should not be treated by itself as proof that a split is blocked.

CPP Credit Splitting After Separation Without Divorce

You do not always need a divorce before CPP credits can be divided. Legally married spouses who separated on or after January 1, 1987 can generally request a split after they have lived apart for at least 12 consecutive months, provided they previously lived together for at least 12 consecutive months.

There is normally no deadline while both separated spouses are alive. If one spouse dies, however, the surviving separated spouse must generally apply within 36 months of the death.

Former common-law partners face a different deadline. For a common-law relationship that ended on or after January 1, 1987, the couple generally must have lived together for at least 12 consecutive months and then lived apart for at least 12 consecutive months. The application generally must be made within 48 months after they began living apart. If the former common-law partner is still alive, that person can agree in writing to waive the 48-month deadline.

These timing differences matter. A divorced person with a post-1986 divorce generally has no time limit, while a former common-law partner can lose access to a split by missing the applicable deadline unless the former partner agrees to waive it.

Does Credit Splitting Always Increase Your CPP?

No. A credit split can increase, decrease or leave a person’s CPP benefits unchanged, depending on the pensionable earnings recorded for both people during the eligible years and the rest of their CPP histories.

The lower earner during the relationship is more likely to gain pensionable earnings from the split, while the higher earner may lose them. However, CPP calculations contain other provisions, including rules that can exclude certain periods of low earnings. As a result, looking only at the difference between the spouses’ salaries does not tell you exactly how much either pension will change.

Credit splitting can also help someone establish eligibility for CPP. A CPP retirement pension requires at least one valid contribution, and valid contributions can include credits received from a spouse or common-law partner after divorce or separation. The broader CPP eligibility rules still apply.

The part we would not do is assume that an equal split of pensionable earnings means the two former partners will eventually receive equal CPP pensions. Only eligible relationship-period credits are divided. Each person keeps the rest of their individual contribution history, and factors such as starting age can still change the pension they eventually receive.

Can a Separation Agreement Stop CPP Credit Splitting?

Generally, simply writing into a separation or divorce agreement that CPP credits will not be split does not necessarily stop the division. CPP is governed by federal legislation, and the credit-splitting rules determine whether an agreement can prevent a split.

There are exceptions. Qualifying agreements made before June 4, 1986 can prevent credit splitting. CPP rules also recognize agreements in Quebec, Saskatchewan, British Columbia and Alberta where provincial legislation permits spouses to agree not to split CPP pension credits, provided the applicable requirements are met.

Because this area depends on the date, province and wording of the agreement, we would not rely on a general waiver clause without checking whether it actually satisfies the CPP requirements. The current credit-splitting eligibility rules set out the agreement exceptions.

What Happens If You Are Already Receiving CPP?

Credit splitting can still matter when CPP benefits are already being paid. The split permanently changes the affected pensionable earnings record, so CPP benefits can be recalculated using the revised record.

That can result in one former partner’s pension increasing and the other’s decreasing. It is not a temporary transfer between monthly payments. The underlying CPP records have changed permanently.

This is different from CPP pension sharing between spouses. Pension sharing applies to spouses or common-law partners who are together and allows eligible CPP retirement pensions to be shared while the relationship continues. Credit splitting deals with pensionable earnings after a relationship has ended.

How Credit Splitting Can Affect a Future Survivor’s Pension

A rule that took effect in January 2025 created an important consequence for some separated but still legally married spouses. If a separated legal spouse has a CPP credit-split request involving the same contributor received and approved in January 2025 or later, that spouse is no longer eligible for a CPP survivor’s pension from that contributor.

There is an exception when the separated spouses reconcile and live together again for at least 12 months immediately before the contributor’s death. Otherwise, the credit split can affect more than the two retirement records. It can also remove a future survivor’s-pension entitlement for a separated legal spouse.

This rule is particularly important because divorced former spouses and former common-law partners already do not have the same survivor status as a current spouse or common-law partner. Anyone considering a credit split while still legally married should understand the survivor-benefit consequence alongside the potential change to their CPP record. The separate CPP survivor benefit calculation explains how that pension works when a person remains eligible.

How to Apply for CPP Credit Splitting

Either former spouse or common-law partner can request a credit split when the eligibility requirements are met. You do not need your former partner to submit a joint application simply because you are the person requesting the division, although special deadline waivers can require the former partner’s written agreement.

You can apply for CPP credit splitting online through My Service Canada Account. Supporting documents still need to be mailed when required. Alternatively, you can complete Form ISP1901, Application for a Canada Pension Plan Credit Split, and submit the form and supporting documents by mail.

Information about the period you lived together is shared with the former spouse or common-law partner because it affects the division. Both people can challenge the information used and appeal a decision about the credit split.

After the split is processed, checking your CPP contribution record is a useful final step. A “CS” notation identifies a year affected by credit splitting, allowing you to see which pensionable earnings were changed rather than waiting until retirement to discover the revised record.

Other Questions About CPP After Divorce

Can your ex refuse a CPP credit split?

For a divorce or annulment on or after January 1, 1987, a former spouse generally cannot prevent an otherwise valid split simply by refusing to cooperate. Different rules apply where a deadline waiver or a legally recognized agreement preventing a split is involved.

Can you request a credit split after remarrying?

Yes. Remarrying or entering a new common-law relationship does not prevent you from requesting an eligible CPP credit split from a previous relationship.

Does CPP credit splitting divide your RRSP or workplace pension too?

No. CPP credit splitting deals specifically with pensionable earnings under the Canada Pension Plan. RRSPs, workplace pensions and other family property follow their own legal and plan rules.

Can a CPP credit split be reversed later?

Credit splitting permanently changes the affected CPP earnings records. It is not a temporary pension-sharing arrangement that former spouses can simply cancel after the division has been completed.

Does a credit split affect CPP disability benefits?

It can. Because a credit split changes the CPP contribution record, it can affect eligibility for or the amount of current or future CPP benefits, including disability benefits. The result depends on the person’s revised contribution history and the eligibility rules for the particular benefit.
