If you have been visited by a High Court Enforcement Officer who has been instructed to remove you from your home or place of business, this means that the case has already been sent to the High Court and a Writ of Possession has been issued.
You must leave the property by the date on your Notice of Eviction, which is usually 14 days unless otherwise specified by the court.
If you do not leave voluntarily the High Court Enforcement Officer is able to physically remove you.
If you are concerned about your living situation, there are various organisations that can offer you independent advice. You can find more information here.
