To hang around with them, you'd think it was entirely amicable and you'd wonder why they even split - they seem to have a better relationship than many married couples I know. The only sticking point seems to be the finances, especially now that NCP has finally decided to take more time with the kids. At least they do a good job of keeping it away from the children. With no child support being paid, at least there's no doubt it isn't about the money so I guess that's a good sign.
There was no equalization done, NCP left with what he came into the marriage with and anything he purchased during the marriage, same for CP. The only things really accumulated during the marriage were things the CP inherited or was given by family when they downsized which pretty much furnished their home. The only assets between them are the house, CP has assumed the mortgage since the split, NCP was given a furnished house that is mortgage free. The house was previously inhabited by only one person ergo, only has one bed, dresser etc. IMO, it isn't too much at all to expect him to purchase furniture, even used furniture for the kids and supply them with some clothing as well for their time with him. But that's my opinion and I'm a little biased having watched her for years work her butt off to provide for them and rarely ever ask him for anything.
I agree he shouldn't be in the CP's house unless invited and she should get her keys back or have the locks changed. If things disappear she won't bother to fight over it but would like to head things off before they go in that direction.
The neutral drop off and pick up spot for the bus is a good idea and may be managable. The only concern with that I guess would be what happens if the bus doesn't come (they live in the country, it's happened a bunch of times) but as long as they have a place to get indoors to it should work out. I'll definately suggest it to her.
CP and the kids live a very modest life and are quite happy doing so, the kids are not lacking for anything unless you include an x-box or iphones, like all kids seem to want these days. I think things always seem so amicable between them because she refuses to engage with him over anything, especially money. She is very happy that he's decided he wants to spend more time with the children and they want that too. It should be a win-win situation for all but I can see her frustration in having to even try to explain to him that he can't have all he's asking for.
