Cutting off toxic family members?

I will be leaving next month and my family has a tendency of trying to include themselves in my life when I don't want them too - for example in my last place they kept calling and calling until I got my number changed then used law enforcement to harass me until I had to threaten them with legal action through an attorney.. my family csnt move on and live their lives their extremely toxic and dysfunctional and I don't want them included in my new life ( they figure their suppose to) when I say I don't want them included talking about no contact. Since we have been back, they have created more problems and drama. Every day, all-day drama, drama, arguments, arguments, problematic etc
