If a child's mother has sole custody then the courts have decided this and there is a reason for it. Generally, if the mother is a good mother (fit mother) then the children will be looked after by her with the father having partial custody to see his children. If the father is unfit, then the mother would have full custody. If you are the child asking the question and are upset because your mother has house rules and you don't always agree with them then this is not a good reason to want to live with your father. Your mother gives you these responsibilities so you will learn good characteristics that will make your life a whole lot simpler. You may not see that now, but will in the future. If this is the father asking the question and you have partial custody the courts have deemed it this way for a reason. If the mother is unfit and the father wants to take full custody then you should retain a lawyer asking for full custody.
That's up to the interpretation of the judge. see link
When the issue pertains to unmarried couples the law presumes the mother to have full legal custody of the child(ren). The father must establish paternity before custody, child support or visitation rights can be addressed by the court.
