The split custody with child support formula should be used where each of the parties has the primary residence of one or more children of the marriage as defined by s. 8 of the Child Support Guidelines. This formula should be used whenever the parties have split custody, whether the payor is paying child support in the set-off amount prescribed by the Guidelines or another amount. CSG s. 8; SSAG §8.7
This formula is similar to the basic with child support formula, save that from each party’s individual net disposable income is deducted:
The information required to perform this calculation is:
In this formula, the calculation for quantum is designed to leave the recipient with 40 to 46 percent of the parties’ combined individual net disposable incomes, net of all taxes, deductions, benefits and credits, including those relating to the payment and receipt of spousal support, and double the full table amount of child support. SSAG §8.7
Duration is initially indefinite, duration not specified, however the formula generates a range for duration which can be used to shape duration through subsequent processes of review and variation. The range for duration is determined by selecting the longest results from two tests for the low end of the range and two tests for the high end of the range. The longest test from each becomes the low end of the range and the high end of the range for the duration of spousal support. SSAG §8.7
Payments range from the amount that would leave the recipient with 40 percent (low end of the range) to 46 percent (high end of the range) of the parties’ combined individual net disposable incomes. A notional amount of child support for the children in the care of the party plus the actual table amount of child support for the children in the care of the other party must be deducted from each party’s income in calculating individual net disposable income. SSAG §8.7
The range for duration is the range between the longest of the results produced by the low end of the range tests and the longest of the results produced by the high end of the range tests. SSAG §§8.5.4, 8.7
The low end of the range tests are:
NOTE: Where the youngest child is in school at the date of separation, the applicable test will be 0.5 years per year of cohabitation.
The high end of the range tests are:
The maximum duration spousal support will be payable for is indefinite, duration not specified when:
NOTE: Duration is to include any period in which support or its equivalent was paid on an interim basis pending a final determination of the issue. In other words, the number of months during which interim support or its equivalent was paid should be deducted from the results produced by the formula for duration. SSAG §5.3
In cases where the payor is a step-parent to some or all children of the marriage, the basic, shared custody or split custody with child support formulas will apply to determine the amount and duration of spousal support as usual, subject to two modifications. SSAG §8.8
The custodial payor formula should be used where spousal support is to be paid by the party with the children’s primary residence, whether or not the party receiving spousal support is actually paying child support. SSAG §8.9
This hybrid formula, based on the with child support formula, requires the deduction of the grossed up table amount of notional child support, plus the grossed up amount of any contributions to the children’s special expenses, from the payor’s gross income and the deduction of the grossed-up table amount of child support, plus any contributions to the children’s expenses, from the recipient’s gross income. SSAG §8.9
The information required to perform this calculation is:
The formula for quantum is based on the parties’ gross incomes, less a grossed up amount of child support attributed to each party. SSAG §8.9
Duration in this formula is based on the length of the time the parties lived together, including any periods of cohabitation prior to the marriage. SSAG §8.9
The maximum amount payable is reached when length of cohabitation reaches 25 years, 37.5 percent (low end of the range) of the adjusted gross income difference to 50 percent (high end of the range). The high end of the range for amount may be limited at a lower amount as a result of the “equalization of net income cap” which will ensure that the recipient will not receive an amount of support that would leave him or her with more than 50 percent of the parties’ net disposable income. SSAG §§8.9
Spousal support will be payable for a length of time equal to 0.5 years (low end of the range) to 1.0 years (high end of the range) per year of cohabitation. SSAG §8.9
The maximum duration spousal support will be payable for is indefinite, duration not specified when:
NOTE: Duration is to include any period in which support or its equivalent was paid on an interim basis pending a final determination of the issue. In other words, the number of months during which interim support or its equivalent was paid should be deducted from the results produced by the formula for duration. SSAG §5.3
NOTE: The Advisory Guidelines allow an exception to extend the calculation of duration, and possibly the calculation of quantum, under the custodial payor formula where the parties’ relationship was shorter and the children are younger where the exception is necessary to assist the recipient of spousal support in fulfilling his or her parenting role. SSAG §12.9
The adult children formula applies only where all children of the marriage are at or above the age of majority and child support is wholly determined under s. 3(2)(b) of the Child Support Guidelines. This formula should not be used if there are any children for whom support is being paid under ss. 3(1) or (2)(a) of the Guidelines. SSAG §8.10
This hybrid formula, based on the with child support formula, requires the deduction of the grossed up amounts each party actually contributes to the support of the children, however the amount of support is determined, from the gross incomes of each party.
The information required to perform this calculation is:
Payor’s Gross Income, determined in accordance with the Child Support Guidelines
Amount of Payor’s Contributions to the Children’s Support
Recipient’s Gross Income, determined in accordance with the Child Support Guidelines
Amount of Recipient’s Contributions to the Children’s Support
Available Credits, Benefits and Deductions relating to the children’s special expenses
Age of Recipient
Length of Cohabitation, calculated from date of marriage to date of separation, plus any period of cohabitation before marriage
In this formula, quantum is based on the parties’ gross incomes less the amount of each party’s actual contributions to the children’s support. SSAG §8.10
Duration is based on the length of the time the parties lived together, including any periods of cohabitation prior to the marriage. SSAG §8.10
This formula requires the adjustment of the parties’ gross incomes to subtract the grossed up amount of each party’s actual contributions to the children’s support.
Payments range from 1.5 percent (low end of the range) to 2.0 percent (high end of the range) of the difference between the parties’ adjusted gross incomes per year of cohabitation. SSAG §8.10
The maximum amount payable is reached when length of cohabitation reaches 25 years, 37.5 percent (low end of the range) of the adjusted gross income difference to 50 percent (high end of the range). The high end of the range for amount may be limited at a lower amount as a result of the “equalization of net income cap” which will ensure that the recipient will not receive an amount of support that would leave him or her with more than 50 percent of the parties’ net disposable income. SSAG §8.10
Spousal support will be payable for a length of time equal to 0.5 years (low end of the range) to 1.0 years (high end of the range) per year of cohabitation. SSAG §8.10
The maximum duration spousal support will be payable for is indefinite, duration not specified when:
NOTE: Duration is to include any period in which support or its equivalent was paid on an interim basis pending a final determination of the issue. In other words, the number of months during which interim support or its equivalent was paid should be deducted from the results produced by the formula for duration. SSAG §5.3
