Cross-Border Family Law for Washington Residents. Divorce, custody, support, or property that crosses the 49th parallel needs a plan that works on both sides of the border. A Washington court cannot issue binding orders regarding real estate located in British Columbia, and U.S. custody agreements are not automatically recognized across the border. Sea to Sky Law represents Washington state residents in the B.C. Supreme Court and has decades of experience in both the B.C. Provincial Court and the B.C. Supreme Court. Common cross-border challenges include B.C. property and asset division, cross-border child custody and parent relocation under the Hague Convention on International Child Abduction, enforcing and modifying support orders across the border, and parallel divorce proceedings where jurisdiction must be decided (forum non conveniens). We are a British Columbia law firm. We advise on B.C. law and work alongside your U.S. attorney on cross-border matters; for questions only about Washington law we will point you to a Washington lawyer. Consultations are by phone or secure video. Serving clients across British Columbia since 1991.
