Commonly Asked Questions
Should I buy a U.S. property in my personal name if I am a Canadian citizen and Canadian resident?
Is owning U.S. property in a trust advisable for a Canadian resident?
My father owns a condo in Fort Lauderdale, Florida and is a resident of Montreal, Canada. Unfortunately, he can no longer go there as he now has Alzheimer’s and we need to sell the condo. Can he still sign the seller documents?
Attorney (executed while he was competent) or by a court-appointed legal representative. The Power of Attorney must be reviewed by the Florida title company to ensure it meets state requirements and is properly authenticated. If no valid Power of Attorney exists, you may
need to establish a tutorship/curatorship in Quebec and have the representative’s authority recognized in Florida. The process to have the representative’s authority recognized in Florida is through a guardianship petition in the county courthouse where the property lies. This petition can be onerous, expensive and time consuming, requiring Florida counsel to petition the court on your behalf. It also risks delaying the property sale, as the sale cannot close until the court has formally appointed the guardian, which can take several months. A Guardianship proceeding will also require notifying certain family members about the application, often requiring their signed consent or otherwise providing them with formal legal notice. If certain family members wish to interject, or disagree on who should act as guardian, this can further complicate and delay the process. For this reason, it is important that owners of US real estate sign a properly drafted Florida power of attorney while competent to do so. Owners should not rely on Canadian protection mandates or powers of attorney, as they likely do not meet the strict requirements of a Florida power of attorney, and would require a court petition nonetheless.
I have three rental properties in the U.S. but I reside in Toronto. I am worried about what happens if a tenant has a slip and fall in one of the properties and is severely injured or dies from the accident. Do I have liability if the property is in my name personally?
If I sell my U.S. property for a profit as a Canadian citizen and resident of Canada, do I have to pay capital gains tax to the IRS? Do I have to pay capital gains tax to the CRA?
