What the order actually reaches
Most orders cover more than showing up in person. They commonly reach calls, texts, email, social media, and messages passed through friends or relatives, and many also name a home, a workplace, a school, or a building. The scope varies a great deal from one order to the next, which is why the words on the paper matter more than what anyone told you in the hallway. Read it line by line, and ask about anything that is not obvious, including whether it covers a shared phone plan or a shared account.
The most common way people get into trouble
The protected person reaches out first. It happens often, it feels like permission, and it is not. In most places responding is still a violation, and a new case added to the original one is harder to resolve than the original one was. Save what you receive, send it to your lawyer, and do not answer. The same applies to turning up at a family event you were both invited to, and to letting a relative carry a message that you did not want to send yourself.
How an order gets changed
The protected person usually cannot cancel it, because it is the court's order rather than theirs. An informal agreement between the two of you changes nothing, however sincerely it was made. There is normally a process for asking a court to modify the terms, whether for a child exchange, a shared residence, or a shared workplace, and it runs through the court. In a first conversation we go through exactly what your order covers and which logistics have to be solved this week. We also look at whether asking for a modification is realistic in your situation.
