Form F30: Affidavits in Supreme Court family cases

What the general affidavit form is for, what Rule 10-4 requires and how affidavits fit into applications.

An affidavit is evidence, not argument. Form F30 is the general Supreme Court family affidavit form. The facts must be sworn or affirmed, and Rule 10-4 controls form, identification, exhibits and how affidavits are used.

What is Form F30?

Form F30 is the general Affidavit used in BC Supreme Court family proceedings. Rule 10-4 requires an affidavit used in a family law case to be filed. It must be in the first person, identify the deponent by name, address and occupation, state any required relationship to a party, and use consecutively numbered paragraphs.

The top-right identification

Except for affidavits of service, the first page identifies the deponent, the sequential number of that person’s affidavit in the case and the date it was made. That numbering matters when an application record contains several affidavits from the same person.

Facts versus submissions

An affidavit should set out admissible evidence. It is generally a poor place for rhetoric, insults, legal argument or long narratives unrelated to the orders being sought. Clear chronology, direct knowledge and properly identified exhibits make the evidence easier for the court and the other side to understand.

Exhibits

Documents relied on through an affidavit may need to be attached and properly marked as exhibits under the Rules and commissioning requirements. A large volume of exhibits can increase application-record size and legal cost, so relevance matters.

Swearing or affirming

The affidavit must be sworn or affirmed before an authorized commissioner. Do not sign the jurat as if it were an ordinary declaration before the commissioning step is completed.

Affidavits in the October 2026 application process

For ordinary Rule 10-6 applications, supporting affidavits are part of the material generally served before the application package is filed. Responding affidavits follow the relevant F32 response timetable. This makes early evidence organization important because service now comes before the ordinary filing stage.

Cost planning

Affidavit drafting is an area where limited-scope legal review can be valuable. A lawyer may be able to help remove irrelevant material, identify evidentiary gaps and make sure the affidavit actually supports the legal orders requested without taking over the entire case.
