If the official agreement states that child’s parent is to see her every other Sunday, just two days a month, then your ex cannot be keeping that child more than that (unless you both agree). If your child isn’t returned and being kept longer, you call police and your lawyer.
If grandparents are elderly, there is a concern about current pandemics and spreading the virus. Yes there is custody agreement but there are exceptions. Call your lawyer and ask if you are supposed to be delivering kids to grandparents during pandemics endangering everyone
Does your CO state that you must deliver your child to grandparents and pick her up? Why? CO says mom/dad are to see the kid TWO days a month. Why are you the one driving them around those two measly days. I’d say if mom/dad don’t show to pick the kid up, then the kid stays home. Not driving them to grandparents.
I am all for facilitating children’s relationship with the other parent. But they don’t seem to do their part at all. They barely exercise their two days a month visitation
