Legal Question in Family Law in California

Most courts will consider the custodial day on a school day to begin and end either at the beginning or end of the school day, so as to eliminate calculation of fractional days, particularly since the time spent splitting hairs on that issue will usually cost far more than the difference it makes in a child support calculation and there really is no way to conclusively establish who has "custody" of a child who is in school. I do not practice Family Law in San Diego County, however, so I can not be sure that the local practice is the same as I have described. If they do follow that practice, you would be considered to have custody ten days a month in your example.

In San Diego County the courts calculate the actual hour spent with the child. For example a visit from 8 am to 8 pm is 12 hours. Overnight sleeping hours and school hours are the same as all other hours. Good Luck, Pat McCrary
