Direct answer
The published DTV framework allows the legal spouse and children under 20 of a DTV holder or principal applicant to seek dependant status. Each dependant has a separate application and decision, and the file must establish the principal's DTV basis, the legal family relationship, parental authority where relevant and adequate financial support.

Documents and practical preparation
Marriage and birth records should be official, legible and consistent with passports. Divorce, custody, adoption, name changes or travel without one parent may require additional orders or consents. Translation and legalisation treatment depends on the document country and handling post, so timing must allow for civil-document preparation.
Limits and decisions to check
A partner who is not a legal spouse does not automatically fit the dependant category, and a child who has reached the published age limit needs an independent route. The principal's approval does not guarantee a family member's approval, and each entry and stay remains controlled by that person's visa and immigration record.
TVC's practical assessment
Family files fail when the relationship is treated as obvious. A decision-maker sees documents, not family history. We build a clean chain from the principal's DTV to each relationship, explain unusual civil events and align the family's filing sequence rather than submitting disconnected applications.
Can a spouse or child rely on the principal applicant's bank evidence?
Do not assume either that one balance covers the whole family or that every post requires a separate identical balance. Washington's DTV checklist allows family bank evidence with relationship evidence and a sponsorship letter in the circumstances it describes. Confirm the handling post's current requirements for each dependant before arranging funds. Financial eligibility is separate from TVC's professional-fee discount.
