Something to be careful about:
I know brother who got DFed and went through the reinstatement process just to speak to family and for no other reason. He had to attend meetings for about a year and fake genuine obedience to Watchtower to get reinstated. When he was reinstated he didn’t attend another meeting! The elders were so angry that they had been “duped” that they watched this brother for years and got him DFed years later (when he had moved to a different town) for something else.
So if you get reinstated just for family it’s probably best not to rub it in their faces. At least attend the odd meeting afterward and fade. All depending on your ultimate goal, of course, but it’s worth bearing in mind that elders can be vindictive if they think you have “played the system” as they would see it.
