Common Custody Mistakes in BC Divorce: What Judges See Parents Get Wrong

Family lawyers in British Columbia see the same mistakes damage custody cases over and over. Most aren't dramatic — they're quiet misjudgments that seem reasonable in the moment but create serious problems in court. Understanding what judges consistently view as red flags helps you avoid undermining your own position.

Treating Parenting Time as Your Right Instead of the Child's Need

The most fundamental mistake parents make is framing custody as something they deserve. Under Section 37 of BC's Family Law Act, the court's sole consideration is the best interests of the child — not what's fair to the parents.

A parent who argues "I should get 50/50 because it's my right" misses the point entirely. The court wants to hear why a specific arrangement serves the child's developmental needs, emotional stability, and safety. Successful parents frame their proposals around the child: "This schedule maintains the child's school routine and proximity to both households" beats "I deserve equal time."

Using Vague Language in Your Agreement

Agreements that say "reasonable and generous parenting time" or "holidays to be shared as agreed" are guarantees of future conflict. Every undefined term becomes a dispute waiting to happen.

Courts prefer — and experienced family lawyers insist on — specificity: exact days and times for regular parenting, named holidays with alternating-year assignments, defined summer vacation blocks with selection deadlines, and precise transition locations and times. A five-page agreement with clear terms prevents more conflict than a two-page agreement with flexible language.

Badmouthing the Other Parent

Section 37(2)(f) of the Family Law Act evaluates each parent's willingness to foster the child's relationship with the other parent. Judges take this factor seriously. If you're telling the child negative things about their other parent, posting about your ex on social media, or undermining the other parent's authority during their parenting time, the court will weigh it against you.

This cuts both ways — documenting the other parent's alienating behaviour (through saved messages, screenshots, or your child's counsellor) can support your position. But the parent who rises above conflict consistently looks better than the one who engages in it.

Moving Without Following Relocation Rules

Parents sometimes assume they can move and adjust the parenting schedule afterward. Under BC's Family Law Act, a move that significantly impacts the child's relationship with the other parent requires 60 days' written notice. Do not assume that a nearby move automatically qualifies as relocation; if the move does qualify, failing to give notice can lead to a court application.

Withholding Financial Disclosure

Both parents are under a strict statutory obligation to provide full financial disclosure in any child support proceeding. This means the three most recent personal income tax returns, the three most recent CRA Notices of Assessment, and current pay stubs or business records. Hiding income, delaying disclosure, or providing incomplete information doesn't work — courts can impute income based on earning capacity and order retroactive support. It also damages your credibility on every other issue.

Making Unilateral Major Decisions

If you're a guardian, your parental responsibilities are set by agreement or order and may be shared or allocated. Enrolling the child in a new school, changing their doctor, booking major medical procedures, or signing them up for religious instruction without consulting the other parent can conflict with those responsibilities and courts may view it unfavorably.

If you genuinely believe the other parent will unreasonably withhold consent, apply to court for sole decision-making authority on the specific issue — don't act unilaterally.

Ignoring the Mandatory Pre-Court Steps

In designated BC Provincial Court registries, you must complete the Early Resolution Process before filing a custody application: needs assessment, Parenting After Separation course, and at least one attempt at consensual dispute resolution. Skipping these steps may mean you cannot file the application at that registry — wasting time and creating the impression that you don't take the process seriously.

Using the Child as a Messenger

Asking your child to relay schedule changes, deliver support cheques, or communicate your frustrations to the other parent puts the child in an impossible position. Courts view this as harmful to the child's well-being and evidence of poor judgment. All communication about logistics should happen directly between parents — preferably in writing.

Failing to Document

If the other parent is consistently late for pickups, missing parenting time, or violating the agreement in other ways, you need a record. Verbal complaints months later carry little weight compared to a contemporaneous log with dates, times, and specifics. Keep a simple written record — not to build ammunition, but to provide accurate evidence if you ever need to seek a variation.

Getting the Fundamentals Right

Most custody mistakes stem from not understanding what BC courts actually evaluate and value. The British Columbia Child Custody & Parenting Plan Guide walks you through the best interests factors, required agreement elements, and communication protocols that experienced family lawyers recommend — so you're building your case on a solid foundation from day one.
