Nesting in Massachusetts for custody cases involves somewhat a unique situation where the idea that the children would remain in the former marital home and the two parties would live somewhere else for a period of time.  So, for example, it could be a joint legal and joint physical custody situation where the mother might be in the household Monday, Tuesday and father Wednesday, Thursday and alternating weekends and each of the parents has a different place to live when they are not at the home and they would not be in the home together.

There are certainly some advantages with it.  A lot of times it is difficult for divorcing couples to be able to do something like this in terms even sharing peanut butter or little things like that to if people become involved with another relationship, etc.  Sometimes people feel that this can be best for the children because it is keeping the consistency and in the same household.  It is fairly rare in Massachusetts but you do see it occurring sometimes.
