BC Spousal Support Calculator — Spousal Support Advisory Guidelines. The Spousal Support Advisory Guidelines provide a framework for calculating the amount and duration of spousal support in British Columbia. The guidelines are not binding law but are widely used by BC lawyers and courts as a starting point. The without child support formula applies when the spouses do not have dependent children and calculates support based on the difference in the parties' incomes and the length of the relationship. The with child support formula applies when there are dependent children and child support is also being paid. Both formulas produce a range of monthly amounts and a range of duration, giving parties room to negotiate. Compensatory support recognises economic disadvantage caused by the roles one spouse took during the relationship. Non-compensatory support addresses financial need. Duration of spousal support may be time-limited or indefinite, with indefinite support more likely in long relationships where the lower-income spouse has limited ability to become self-sufficient. Spousal support paid under a written agreement or court order is generally deductible to the payor and taxable to the recipient. Andrew Liggett has provided spousal support advice to BC payors and recipients since 1991. This calculator provides estimates only and is not a substitute for legal advice. Spousal support entitlement must first be established before amount and duration are calculated. Independent legal advice from a BC family lawyer is strongly recommended before relying on any estimate or agreeing to any spousal support amount.
