The answer
The answer can arise from agreement, current occupation, safety planning, an exclusive-possession order or another legal order, not merely title or who paid more. Alberta describes exclusive possession as an interim arrangement until the couple or court decides occupation and property division; it does not itself determine final ownership.
Calgary-specific context
Calgary applicants may need to follow Alberta's Family Justice Strategy before court steps.
What to do next
Document current occupants, safety, children, pets, access and costs and obtain family-law advice before changing locks or removing belongings.
