If there are NO current orders...and if the kids are in daycare or school...then there is nothing stopping you from seeing them there. Probably would make the ex go ballistic and she would probably try to get the daycare or school to refuse you access (which she canNOT do, only a judge can)...so you have to weigh the options that would be best for the kids, since they would be present. But.....if you do try to see them there, make sure you take someone with you (preferably a family member, NOT a GF) AND some kind of recording device, preferrably a camcorder. To prove that your intent is ONLY to see the children and that you were calm, cool, and collected.....vs. the ex's 'response'.
