If you and a co-parent are transitioning to separate living arrangements, child support is a critical aspect that requires immediate attention. It’s imperative to remember that every child is entitled to financial support, which is non-negotiable from either parent.
Legal Obligations and Child Support
The law mandates that parents must provide essential life needs for their children. Moreover, the change in family dynamics due to parental separation should not compromise a child’s quality of life. Despite the best intentions, discussions surrounding child support can become contentious. In such situations, an experienced child support attorney can help mediate a fair arrangement. If an agreement is not possible, or if there’s a need to alter an existing support order, legal representation can be crucial.
Calculating Child Support: The Ontario Framework
The applicable child support guidelines depend on the legal framework. The Federal Child Support Guidelines generally apply under the Divorce Act; Ontario’s Child Support Guidelines generally apply under the Family Law Act. The applicable rules consider income, the number of children and the parenting arrangement. Your lawyer can identify the appropriate guidelines and tables. See the Department of Justice guide to determining which guidelines apply.
Child support calculations should account for the children who qualify under the applicable law. Support usually applies to dependent children under the age of majority and may continue for an adult child who remains dependent, including because of education, illness or disability. See the Department of Justice guidance on children requiring support.
Qualifying special or extraordinary expenses may be payable in addition to basic support. Section 7 addresses specified childcare, health and education expenses, as well as extraordinary extracurricular expenses. Whether an expense qualifies depends on criteria including necessity for the child and reasonableness in the family’s circumstances; not every additional expense is automatically included. See section 7 of the Federal Child Support Guidelines.
Challenges in Determining Child Support Payments
To navigate the complexities, a child support lawyer can collaborate with financial experts to assess income. Certain legal fees paid by a support recipient to establish, increase or enforce support, or defend against a reduction, may be deductible. A support payer cannot deduct fees to establish, negotiate, contest, reduce or terminate support. Ask a tax professional which fees qualify in your circumstances. See the CRA’s guidance on legal and accounting fees for support.
Modifying Child Support Arrangements
Child support payments may warrant adjustment if there’s a significant change in parental income, time spent with the child, or the child’s specific needs. A notable increase or decrease in a parent’s income, or changes in the child’s needs—like orthodontic treatment or higher education—can be grounds for modification.
It’s crucial to understand that a receiving parent’s new relationship status does not alter the contributing parent’s financial obligations towards the child. For advice tailored to your circumstances, consult a specialized child support attorney.
