Criminal trespass in Philadelphia is charged when someone knowingly enters or stays on another person’s property without authorization. Depending on the facts, this can be classified as either a misdemeanor or felony. In some cases, people are charged with trespassing after being asked to leave or after entering a vacant building. A criminal defense lawyer in Philadelphia can help determine whether the entry was truly unauthorized, whether proper notice was given, and whether there is enough evidence to support the charge. Criminal trespass may seem minor, but a conviction can carry real consequences for your record and future.
