When to use a general supporting affidavit
General supporting affidavits are used to put facts before the court when:
- You're responding to a motion brought by the other party
- You're filing your own non-urgent, non-variation motion (e.g., motion for contempt, motion for case management)
- The matter doesn't fit Form 14A (ON), Form F1 (BC), Form 49 (AB), or NB Rule 60 specialized affidavits
- You need to put updated facts before a case conference or settlement conference
Structure that judges expect
- Court heading + file number + style of cause
- Opening declaration identifying you, your city, your role in the matter
- Brief background — your relationship to the parties (1-2 paragraphs)
- Chronological account of relevant events — each dated, first-person, with named witnesses
- Specific exhibits referenced as you go ('A true copy of the text thread is attached and marked as Exhibit A')
- Brief relief context — how these facts support what the motion is asking for
- Jurat — sworn before a commissioner
What evidence belongs in a supporting affidavit
The court will weigh dated, first-person observations supported by documentary exhibits. The most useful types:
- Text messages between the parties (screenshots with full thread context, dated)
- Email correspondence (full original, including headers)
- Schedules showing missed or successful exchanges
- School records (report cards, attendance, communications)
- Medical records (with consent or court order)
- Police reports / incident numbers
- Photographs (with date metadata)
- Financial documents — tax returns, pay stubs, bank statements for relevant accounts
Frequently asked
How many paragraphs is too many?
Most family-court affidavits run 10-30 numbered paragraphs (3-10 pages). Some jurisdictions have page caps without leave. Quality beats volume — a tight 12-paragraph affidavit with 6 well-marked exhibits is more persuasive than a 40-paragraph narrative.
Should I include legal argument in my affidavit?
No. Affidavits are evidence. Legal argument goes in your factum or oral submissions at the hearing. Mixing the two confuses judges and weakens both. If you're tempted to write 'this proves...', stop — that's argument.
What if some of my evidence is hearsay?
Either get the original witness to swear their own affidavit, or rephrase as direct observation ('I observed bruising on my son's arm when I picked him up' instead of 'his teacher told me about bruising'). Some hearsay exceptions exist but they're advanced — for self-rep practice, stick to direct observation.
