Many courts in Georgia are not closed for Presidents' Day (Monday, February 18th). If you have a filing deadline that falls on Monday, call the court to see if it will br opened.
Extreme caution should be exercised for dispossessory answers that are due this Monday. Unlike regular court actions, opening a default in an dispossessory action is nearly impossible. As a result, a landlord may apply for a writ on Tuesday if an answer isn't filed timely. Once the judge grants the writ, it's only a matter of time before the Sheriff/Marshal comes to supervise the eviction.
