Child Support in BC: Complete Guide to Calculations, Special Expenses, and Enforcement

child support

When parents separate or divorce, one of the most critical issues is ensuring children receive adequate financial support. Understanding BC’s child support system can help protect your children’s future and your parental rights.

Can Parents Agree to Waive Child Support?

The short answer is: No.

This is one of the most misunderstood aspects of family law. Under both the Divorce Act and BC’s Family Law Act, child support is the child’s right, not the parents’ right to waive. Courts consistently hold that parents cannot bargain away their children’s entitlement to financial support.

Why This Rule Exists

  • Children’s needs transcend parental agreements
  • Society has an interest in preventing children from becoming dependent on public assistance
  • Parents’ circumstances and attitudes may change over time
  • Children cannot advocate for themselves in legal proceedings

How Child Support is Calculated in BC

The Federal Child Support Guidelines

BC follows the Federal Child Support Guidelines, which create uniform support amounts across Canada. The calculation considers:

  1. Payor’s gross annual income
  2. Number of children requiring support
  3. Province of residence
  4. Custody arrangements

Basic Calculation Method

Step 1: Determine the payor’s annual gross income (before taxes and deductions)

Step 2: Consult the Federal Child Support Tables for BC

Step 3: Find the amount corresponding to income and number of children

Special Circumstances in Income Calculation

Fluctuating Income

When annual income varies significantly:

  • Three-year average: Courts typically use the average of the past three years
  • Pattern analysis: Look for trends in income increases or decreases
  • Future projections: Consider whether current income reflects ongoing earning capacity

Self-Employment and Business Income

For business owners or self-employed individuals:

  • Net business income forms the basis for calculation
  • Add back non-essential business expenses
  • Consider company benefits and perks as income
  • Gross up dividends to reflect pre-tax equivalent

International Income: China and Other Countries

Key considerations for overseas income:

  • Convert foreign currency using Bank of Canada rates
  • Include all sources of income (salary, bonuses, benefits)
  • Consider tax equalization if employer pays foreign taxes
  • Apply same calculation principles regardless of work location

Income Imputation: Dealing with Deliberate Underemployment

When a parent deliberately reduces income to avoid support:

Courts can impute income based on:

  • Previous earning history
  • Education and qualifications
  • Available employment opportunities
  • Age and health considerations

Example: A professional who quits to work minimum wage jobs will likely have income imputed at professional levels.

Section 7 Special Expenses: Beyond Basic Support

What Qualifies as Special Expenses?

Under Section 7 of the Guidelines, parents share extraordinary expenses:

Childcare Costs

  • Daycare and after-school care
  • Nannies and babysitters for work-related care
  • Summer day camps

Healthcare Expenses

  • Medical treatments not covered by insurance
  • Dental work beyond basic coverage
  • Vision care and glasses
  • Prescription medications
  • Therapy and counseling

Educational Expenses

  • Private school tuition, if agreed
  • University and college costs
  • Educational tutoring
  • Special needs education

Extracurricular Activities

  • Sports teams and equipment
  • Music lessons and instruments
  • Art classes and supplies
  • Must be reasonable given family income

The “Necessary and Reasonable” Test

Courts apply two criteria:

  1. Necessary: Required for the child’s health, education, or development
  2. Reasonable: Affordable given the family’s financial circumstances

Proportional Sharing

Special expenses are shared based on each parent’s income:

  • Parent A earns $60,000, Parent B earns $40,000
  • Total family income: $100,000
  • Parent A pays 60%, Parent B pays 40%

Out-of-Province Education: Additional Considerations

University Outside BC

When children attend university outside BC, additional costs include:

  • Tuition and fees
  • Residence or accommodation costs
  • Transportation (flights home for holidays)
  • Higher living expenses in expensive cities

Planning tip: Start discussing post-secondary education costs early, ideally in separation agreements.

Duration of Child Support: How Long Do You Pay?

Common Misconceptions

Many parents believe support ends at 18 or 19. This is incorrect.

Actual Duration Under Canadian Law

Support continues until the child:

  • Graduates from post-secondary education, or
  • Becomes financially self-sufficient, or
  • Reaches age of majority and chooses not to pursue further education

Adult Children and Support

Support for adult children depends on:

  • Educational pursuits: Full-time students generally receive continued support
  • Financial independence: Part-time work doesn’t automatically end support
  • Living arrangements: Children living independently may still qualify
  • Special needs: May require lifelong support

Enforcement Through FMEP: BC’s Powerful Collection System

What is FMEP?

The Family Maintenance Enforcement Program (FMEP.gov.bc.ca) is BC’s free government service for collecting unpaid support.

FMEP’s Enforcement Powers

Administrative remedies:

  • Garnish wages directly from employers
  • Seize bank accounts and investments
  • Intercept tax refunds and government benefits
  • Report to credit bureaus
  • Suspend driver’s licenses
  • Refuse passport renewals

Court-based remedies:

  • Contempt of court proceedings
  • Asset seizure and sale
  • Default hearings

International Enforcement

Cross-border collection capabilities:

  • Reciprocal enforcement agreements with many countries
  • Arrest warrants for contempt can be executed internationally
  • China enforcement: Limited but improving through Chinese courts

Modifying Child Support: When Circumstances Change

Material Change in Circumstances

Support can be modified when there’s a material change such as:

  • Significant income increase or decrease (typically 20%+)
  • Change in parenting arrangements
  • Child’s needs change substantially
  • New children in either household

The Process

  1. Attempt negotiation first
  2. File court application if agreement impossible
  3. Provide updated financial disclosure
  4. Attend court hearing if necessary

The Real Cost of Raising Children

Research shows that raising a child to age 18 costs approximately $250,000-$300,000 in Canada. This includes:

  • Housing (largest expense)
  • Food and clothing
  • Healthcare
  • Education
  • Childcare
  • Transportation
  • Recreation and activities

Child support guidelines aim to ensure both parents contribute proportionally to these essential costs.
