In custody cases, a lot of the time for lawyers if you either take notes of what has happened during parenting time with drop off and pickups that is helpful. I sometimes ask clients for a timeline as a starting point; which can give me a better grasp of what is going on in the relationship with the other parent. The good things, the bad things, the strengths and weaknesses of both parties and what some of the concerns are.  So, if you are organized and you are able to take notes or have an idea of terms of the time, that can be helpful thing for custody and parenting cases.
